2020-12-04pinctrl: mtk: Fix low level output voltage issueZhiyong Tao
This patch is used to fix low level output voltage issue. A pin is changed from input pull-up to output high. The Dout value of the pin is default as 0. If we change the direction of the pin before the dout value of the pin, It maybe produce a low level output voltage between "input pull-up" and "output high".

2020-10-07pinctrl: mediatek: Free eint data on failureEnric Balletbo i Serra
The pinctrl driver can work without the EINT resource, but, if it is expected to have this resource but the mtk_build_eint() function fails after allocating their data (because can't get the resource or can't map the irq), the data is not freed and you end with a NULL pointer dereference. Fix this by freeing the data if mtk_build_eint() fails, so pinctrl still works and doesn't hang. This is noticeable after commit f97dbf48ca43 ("irqchip/mtk-sysirq: Convert to a platform driver") on MT8183 because, due this commit, the pinctrl driver fails to map the irq and spots the following bug: [ 1.947597] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000004 [ 1.956404] Mem abort info: [ 1.959203] ESR = 0x96000004 [ 1.962259] EC = 0x25: DABT (current EL), IL = 32 bits [ 1.967565] SET = 0, FnV = 0 [ 1.970613] EA = 0, S1PTW = 0 [ 1.973747] Data abort info: [ 1.976619] ISV = 0, ISS = 0x00000004 [ 1.980447] CM = 0, WnR = 0 [ 1.983410] [0000000000000004] user address but active_mm is swapper [ 1.989759] Internal error: Oops: 96000004 [#1] PREEMPT SMP [ 1.995322] Modules linked in: [ 1.998371] CPU: 7 PID: 1 Comm: swapper/0 Not tainted 5.9.0-rc1+ #44 [ 2.004715] Hardware name: MediaTek krane sku176 board (DT) [ 2.010280] pstate: 60000005 (nZCv daif -PAN -UAO BTYPE=--) [ 2.015850] pc : mtk_eint_set_debounce+0x48/0x1b8 [ 2.020546] lr : mtk_eint_set_debounce+0x34/0x1b8 [ 2.025239] sp : ffff80001008baa0 [ 2.028544] x29: ffff80001008baa0 x28: ffff0000ff7ff790 [ 2.033847] x27: ffff0000f9ec34b0 x26: ffff0000f9ec3480 [ 2.039150] x25: ffff0000fa576410 x24: ffff0000fa502800 [ 2.044453] x23: 0000000000001388 x22: ffff0000fa635f80 [ 2.049755] x21: 0000000000000008 x20: 0000000000000000 [ 2.055058] x19: 0000000000000071 x18: 0000000000000001 [ 2.060360] x17: 0000000000000000 x16: 0000000000000000 [ 2.065662] x15: ffff0000facc8470 x14: ffffffffffffffff [ 2.070965] x13: 0000000000000001 x12: 00000000000000c0 [ 2.076267] x11: 0000000000000040 x10: 0000000000000070 [ 2.081569] x9 : ffffaec0063d24d8 x8 : ffff0000fa800270 [ 2.086872] x7 : 0000000000000000 x6 : 0000000000000011 [ 2.092174] x5 : ffff0000fa800248 x4 : ffff0000fa800270 [ 2.097476] x3 : ffff8000100c5000 x2 : 0000000000000000 [ 2.102778] x1 : 0000000000000000 x0 : 0000000000000000 [ 2.108081] Call trace: [ 2.110520] mtk_eint_set_debounce+0x48/0x1b8 [ 2.114870] mtk_gpio_set_config+0x5c/0x78 [ 2.118958] gpiod_set_config+0x5c/0x78 [ 2.122786] gpiod_set_debounce+0x18/0x28 [ 2.126789] gpio_keys_probe+0x50c/0x910 [ 2.130705] platform_drv_probe+0x54/0xa8 [ 2.134705] really_probe+0xe4/0x3b0 [ 2.138271] driver_probe_device+0x58/0xb8 [ 2.142358] device_driver_attach+0x74/0x80 [ 2.146532] __driver_attach+0x58/0xe0 [ 2.150274] bus_for_each_dev+0x70/0xc0 [ 2.154100] driver_attach+0x24/0x30 [ 2.157666] bus_add_driver+0x14c/0x1f0 [ 2.161493] driver_register+0x64/0x120 [ 2.165319] __platform_driver_register+0x48/0x58 [ 2.170017] gpio_keys_init+0x1c/0x28 [ 2.173672] do_one_initcall+0x54/0x1b4 [ 2.177499] kernel_init_freeable+0x1d0/0x238 [ 2.181848] kernel_init+0x14/0x118 [ 2.185328] ret_from_fork+0x10/0x34 [ 2.188899] Code: a9438ac1 12001266 f94006c3 121e766a (b9400421) [ 2.194991] ---[ end trace 168cf7b3324b6570 ]--- [ 2.199611] Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b [ 2.207260] SMP: stopping secondary CPUs [ 2.211294] Kernel Offset: 0x2ebff4800000 from 0xffff800010000000 [ 2.217377] PHYS_OFFSET: 0xffffb50500000000 [ 2.221551] CPU features: 0x0240002,2188200c [ 2.225811] Memory Limit: none [ 2.228860] ---[ end Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b ]--- Fixes: 89132dd8ffd2 ("pinctrl: mediatek: extend eint build to pinctrl-mtk-common-v2.c") Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Acked-by: Sean Wang <sean.wang@kernel.org> Link: https://lore.kernel.org/r/20201001142511.3560143-1-enric.balletbo@collabora.com [rebased on changed infrastructure] Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2020-02-21pinctrl: Use new GPIO_LINE_DIRECTIONMatti Vaittinen
Use newly added GPIO defines GPIO_LINE_DIRECTION_IN and GPIO_LINE_DIRECTION_OUT instead of using hard-coded 1 and 0. Main benefit is to make it easier to see which values mean IN and which OUT. As a side effect this helps GPIO framework to change the direction defines to something else if ever needed. Please note that return value from get_direction call on pinctrl-axp209 driver was changed. Previously pinctrl-axp209 might have returned value 2 for direction INPUT.

2020-02-14pinctrl: mediatek: Backward compatible to previous Mediatek's bias-pull usageLight Hsieh
Refine mtk_pinconf_set()/mtk_pinconf_get() for backward compatibility to previous MediaTek's bias-pull usage. In PINCTRL_MTK that use pinctrl-mtk-common.c, bias-pull setting for pins with 2 pull resistors can be specified as value for bias-pull-up and bias-pull-down. For example: bias-pull-up = <MTK_PUPD_SET_R1R0_00>; bias-pull-up = <MTK_PUPD_SET_R1R0_01>; bias-pull-up = <MTK_PUPD_SET_R1R0_10>; bias-pull-up = <MTK_PUPD_SET_R1R0_11>; bias-pull-down = <MTK_PUPD_SET_R1R0_00>; bias-pull-down = <MTK_PUPD_SET_R1R0_01>; bias-pull-down = <MTK_PUPD_SET_R1R0_10>; bias-pull-down = <MTK_PUPD_SET_R1R0_11>; On the other hand, PINCTRL_MTK_PARIS use customized properties "mediatek,pull-up-adv" and "mediatek,pull-down-adv" to specify bias-pull setting for pins with 2 pull resistors. This introduce in-compatibility in device tree and increase porting effort to MediaTek's customer that had already used PINCTRL_MTK version. Besides, if customers are not aware of this change and still write devicetree for PINCTRL_MTK version, they may encounter runtime failure with pinctrl and spent time to debug. This patch adds backward compatible to previous MediaTek's bias-pull usage so that Mediatek's customer need not use a new devicetree property name. The rationale is that: changing driver implementation had better leave interface unchanged.

register value MediaTek's smartphone project actual usage does need to know current value (in mA) in procedure of finding the best driving setting. The steps in the procedure is like as follow: 1. set driving setting field in setting register as 0, measure waveform, perform test, and etc. 2. set driving setting field in setting register as 1, measure waveform, perform test, and etc. ... n. set driving setting field in setting register as n-1, measure waveform, perform test, and etc. Check the results of steps 1~n and adopt the setting that get best result. This procedure does need to know the mapping between current to register value. Therefore, setting driving without mapping current is more practical for MediaTek's smartphone usage.

This will affect how the system power management is handled: a pin controller will not suspend before all of its consumers have been suspended. This was necessary for the ST Microelectronics STMFX expander and need to be tested on other systems as well: it makes sense to make this default in the long run. Right now it is opt-in per driver. - Drive strength can be specified in microamps. With decreases in silicon technology, milliamps isn't granular enough, let's make it possible to select drive strengths in microamps. Right now the Meson (AMlogic) driver needs this. New drivers: - New subdriver for the Tegra 194 SoC. - New subdriver for the Qualcomm SDM845. - New subdriver for the Qualcomm SM8150. - New subdriver for the Freescale i.MX8MN (Freescale is now a product line of NXP). - New subdriver for Marvell MV98DX1135. Driver improvements: - The Bitmain BM1880 driver now supports pin config in addition to muxing. - The Qualcomm drivers can now reserve some GPIOs as taken aside and not usable for users. This is used in ACPI systems to take out some GPIO lines used by the BIOS so that noone else (neither kernel nor userspace) will play with them by mistake and crash the machine. - A slew of refurbishing around the Aspeed drivers (board management controllers for servers) in preparation for the new Aspeed AST2600 SoC. - A slew of improvements over the SH PFC drivers as usual. - Misc cleanups and fixes" * tag 'pinctrl-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (106 commits) pinctrl: aspeed: Strip moved macros and structs from private header pinctrl: aspeed: Fix missed include pinctrl: baytrail: Use GENMASK() consistently pinctrl: baytrail: Re-use data structures from pinctrl-intel.h pinctrl: baytrail: Use defined macro instead of magic in byt_get_gpio_mux() pinctrl: qcom: Add SM8150 pinctrl driver dt-bindings: pinctrl: qcom: Add SM8150 pinctrl binding dt-bindings: pinctrl: qcom: Document missing gpio nodes pinctrl: aspeed: Add implementation-related documentation pinctrl: aspeed: Split out pinmux from general pinctrl pinctrl: aspeed: Clarify comment about strapping W1C pinctrl: aspeed: Correct comment that is no longer true MAINTAINERS: Add entry for ASPEED pinctrl drivers dt-bindings: pinctrl: aspeed: Convert AST2500 bindings to json-schema dt-bindings: pinctrl: aspeed: Convert AST2400 bindings to json-schema dt-bindings: pinctrl: aspeed: Split bindings document in two pinctrl: qcom: Add irq_enable callback for msm gpio pinctrl: madera: Fixup SPDX headers pinctrl: qcom: sdm845: Fix CONFIG preprocessor guard pinctrl: tegra: Add bitmask support for parked bits ...
2019-06-27pinctrl: mediatek: Update cur_mask in mask/mask opsNicolas Boichat
During suspend/resume, mtk_eint_mask may be called while wake_mask is active. For example, this happens if a wake-source with an active interrupt handler wakes the system: irq/pm.c:irq_pm_check_wakeup would disable the interrupt, so that it can be handled later on in the resume flow. However, this may happen before mtk_eint_do_resume is called: in this case, wake_mask is loaded, and cur_mask is restored from an older copy, re-enabling the interrupt, and causing an interrupt storm (especially for level interrupts). Step by step, for a line that has both wake and interrupt enabled: 1. cur_mask[irq] = 1; wake_mask[irq] = 1; EINT_EN[irq] = 1 (interrupt enabled at hardware level) 2. System suspends, resumes due to that line (at this stage EINT_EN == wake_mask) 3. irq_pm_check_wakeup is called, and disables the interrupt => EINT_EN[irq] = 0, but we still have cur_mask[irq] = 1 4. mtk_eint_do_resume is called, and restores EINT_EN = cur_mask, so it reenables EINT_EN[irq] = 1 => interrupt storm as the driver is not yet ready to handle the interrupt. This patch fixes the issue in step 3, by recording all mask/unmask changes in cur_mask. This also avoids the need to read the current mask in eint_do_suspend, and we can remove mtk_eint_chip_read_mask function. The interrupt will be re-enabled properly later on, sometimes after mtk_eint_do_resume, when the driver is ready to handle it.

2019-06-26pinctrl: mediatek: Ignore interrupts that are wake only during resumeNicolas Boichat
Before suspending, mtk-eint would set the interrupt mask to the one in wake_mask. However, some of these interrupts may not have a corresponding interrupt handler, or the interrupt may be disabled. On resume, the eint irq handler would trigger nevertheless, and irq/pm.c:irq_pm_check_wakeup would be called, which would try to call irq_disable. However, if the interrupt is not enabled (irqd_irq_disabled(&desc->irq_data) is true), the call does nothing, and the interrupt is left enabled in the eint driver. Especially for level-sensitive interrupts, this will lead to an interrupt storm on resume. If we detect that an interrupt is only in wake_mask, but not in cur_mask, we can just mask it out immediately (as mtk_eint_resume would do anyway at a later stage in the resume sequence, when restoring cur_mask).

It is not easy to merge the 2 copies (or move mtk_eint_suspend/resume to mtk-eint.c), as we need to dereference pctrl->eint, and struct mtk_pinctrl *pctl has a different structure definition for v1 and v2 (which is what paris variant uses).

2019-04-08pinctrl: add drive for I2C related pins on MT8183Zhiyong Tao
This patch provides the advanced drive for I2C used pins on MT8183. The detail strength specification description of the I2C pin: When E1=0/E0=0, the strength is 0.125mA. When E1=0/E0=1, the strength is 0.25mA. When E1=1/E0=0, the strength is 0.5mA. When E1=1/E0=1, the strength is 1mA. For I2C pins, there are existing generic driving setup and the above specific driving setup. I2C pins can only support 2/4/6/8/10/12/14/16mA driving adjustment in generic driving setup. But in specific driving setup, they can support 0.125/0.25/0.5/1mA adjustment. If we enable specific driving setup for I2C pins, the existing generic driving setup will be disabled. For some special features, we need the I2C pins specific driving setup. The specific driving setup is controlled by E1E0EN. So we need add extra vendor driving preperty instead of the generic driving property. We can add "mediatek,drive-strength-adv = <XXX>;" to describe the specific driving setup property. "XXX" means the value of E1E0EN. So the valid arguments of "mediatek,drive-strength-adv" are from 0 to 7.
