2020-11-10pinctrl: qcom: Move clearing pending IRQ to .irq_request_resources callbackMaulik Shah
When GPIOs that are routed to PDC are used as output they can still latch the IRQ pending at GIC. As a result the spurious IRQ was handled when the client driver change the direction to input to starts using it as IRQ. Currently such erroneous latched IRQ are cleared with .irq_enable callback however if the driver continue to use GPIO as interrupt and invokes disable_irq() followed by enable_irq() then everytime during enable_irq() previously latched interrupt gets cleared. This can make edge IRQs not seen after enable_irq() if they had arrived after the driver has invoked disable_irq() and were pending at GIC. Move clearing erroneous IRQ to .irq_request_resources callback as this is the place where GPIO direction is changed as input and its locked as IRQ. While at this add a missing check to invoke msm_gpio_irq_clear_unmask() from .irq_enable callback only when GPIO is not routed to PDC.

2020-11-10pinctrl: amd: use higher precision for 512 RtcClkCoiby Xu
RTC is 32.768kHz thus 512 RtcClk equals 15625 usec. The documentation likely has dropped precision and that's why the driver mistakenly took the slightly deviated value.

2020-11-05pinctrl: mcp23s08: Use full chunk of memory for regmap configurationAndy Shevchenko
It appears that simplification of mcp23s08_spi_regmap_init() made a regression due to wrong size calculation for dev_kmemdup() call. It misses the fact that config variable is already a pointer, thus the sizeof() calculation is wrong and only 4 or 8 bytes were copied. Fix the parameters to devm_kmemdup() to copy a full chunk of memory.

2020-10-26pinctrl: intel: Set default bias in case no particular value givenAndy Shevchenko
When GPIO library asks pin control to set the bias, it doesn't pass any value of it and argument is considered boolean (and this is true for ACPI GpioIo() / GpioInt() resources, by the way). Thus, individual drivers must behave well, when they got the resistance value of 1 Ohm, i.e. transforming it to sane default. In case of Intel pin control hardware the 5 kOhm sounds plausible because on one hand it's a minimum of resistors present in all hardware generations and at the same time it's high enough to minimize leakage current (will be only 200 uA with the above choice).

2020-10-26pinctrl: intel: Fix 2 kOhm bias which is 833 OhmAndy Shevchenko
2 kOhm bias was never an option in Intel GPIO hardware, the available matrix is: 000 none 001 1 kOhm (if available) 010 5 kOhm 100 20 kOhm As easy to get the 3 resistors are gated separately and according to parallel circuits calculations we may get combinations of the above where the result is always strictly less than minimal resistance. Hence, additional values can be: 011 ~833.3 Ohm 101 ~952.4 Ohm 110 ~4 kOhm 111 ~800 Ohm That said, convert TERM definitions to be the bit masks to reflect the above. While at it, enable the same setting for pull down case.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This time very little driver changes but lots of core changes. We have some interesting cooperative work for ARM and Intel alike, making the GPIO subsystem more and more suitable for industrial systems and the like, in addition to the in-kernel users. We touch driver core (device properties) and lib/* by adding one simple string array free function, these are authored by Andy Shevchenko who is a well known and recognized core helpers maintainers so this should be fine. We also see some Android GKI-related modularization in the MXC drivers. Core changes: - The big core change is the updated (v2) userspace character device API. This corrects badly designed 64-bit alignment around the line events. We also add the debounce request feature. This echoes the often quotes passage from Frederick Brooks "The mythical man-month" to always throw one away, which we have seen before in things such as V4L2. So we put in a new one and deprecate and obsolete the old one. - All example tools in tools/gpio/* are migrated to the new API to set a good example. The libgpiod userspace library has been augmented to use this new API pretty much from day 1. - Some misc API hardening by using strn* function calls has been added as well. - Use the simpler IDA interface for GPIO chip instance enumeration. - Add device core function for counting string arrays in device properties. - Provide a generic library function kfree_strarray() that can be used throughout the kernel. Driver enhancements: - The DesignWare dwapb-gpio driver has been enhanced and now uses the IRQ handling in the gpiolib core. - The mockup and aggregator drivers have seen some substantial code clean-up and now use more of the core kernel inftrastructure. - Misc cleanups using dev_err_probe(). - The MXC drivers (Freescale/NXP) can now be built modularized, which makes modularized GKI Android kernels happy" * tag 'gpio-v5.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (73 commits) gpiolib: Update header block in gpiolib-cdev.h gpiolib: cdev: switch from kstrdup() to kstrndup() docs: gpio: add a new document to its index.rst gpio: pca953x: Add support for the NXP PCAL9554B/C tools: gpio: add debounce support to gpio-event-mon tools: gpio: add multi-line monitoring to gpio-event-mon tools: gpio: port gpio-event-mon to v2 uAPI tools: gpio: port gpio-hammer to v2 uAPI tools: gpio: rename nlines to num_lines tools: gpio: port gpio-watch to v2 uAPI tools: gpio: port lsgpio to v2 uAPI gpio: uapi: document uAPI v1 as deprecated gpiolib: cdev: support setting debounce gpiolib: cdev: support GPIO_V2_LINE_SET_VALUES_IOCTL gpiolib: cdev: support GPIO_V2_LINE_SET_CONFIG_IOCTL gpiolib: cdev: support edge detection for uAPI v2 gpiolib: cdev: support GPIO_V2_GET_LINEINFO_IOCTL and GPIO_V2_GET_LINEINFO_WATCH_IOCTL gpiolib: cdev: support GPIO_V2_GET_LINE_IOCTL and GPIO_V2_LINE_GET_VALUES_IOCTL gpiolib: add build option for CDEV v1 ABI gpiolib: make cdev a build option ...

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>

msmgpio irqchip was not using return value of irq_set_irq_wake() callback since previously GIC-v3 irqchip neither had IRQCHIP_SKIP_SET_WAKE flag nor it implemented .irq_set_wake callback. This lead to irq_set_irq_wake() return error -ENXIO.

2020-09-29pinctrl: imx: Use function callbacks for SCU related functionsAnson Huang
Use function callbacks for SCU related functions in pinctrl-imx.c in order to support the scenario of PINCTRL_IMX is built in while PINCTRL_IMX_SCU is built as module, all drivers using SCU pinctrl driver need to initialize the SCU related function callback, and no need to check CONFIG_PINCTRL_IMX_SCU anymore, hence stub functions also can be removed.
