The Aspeed pinconf data structures are split into 'conf' and 'map' types, where the 'conf' struct defines which register and bitfield to manipulate, while the 'map' struct defines what value to write to the register and bitfield.

2020-09-15pinctrl: renesas: Reintroduce SH_PFC for common sh-pfc codeGeert Uytterhoeven
Most, but not all, Renesas pin control drivers use the "sh-pfc" pin control framework. As of commit 8449bfa9e6a9f7ec ("pinctrl: sh-pfc: Collect Renesas related CONFIGs in one place"), the code for this framework is always built when Renesas SoC pin control support is enabled, regardless of whether the enabled pin control drivers need it or not. Fix this by reintroducing the CONFIG_SH_PFC symbol to control inclusion of the "sh-pfc" framework and its dependencies, and selecting it when needed. This reduces kernel size of a typical RZ/A1 or RZ/A2 kernel by more than 6 resp. 11 KiB.

2020-09-15pinctrl: Rename sh-pfc to renesasGeert Uytterhoeven
The drivers/pinctrl/sh-pfc subdirectory was originally created to group pin control drivers for various Renesas SuperH and SH-Mobile platforms. However, the name "sh-pfc" no longer reflects its contents, as the directory now contains pin control drivers for Renesas SuperH, ARM32, and ARM64 SoCs. Hence rename the subdirectory from drivers/pinctrl/sh-pfc to drivers/pinctrl/renesas, and the related Kconfig symbol from PINCTRL_SH_PFC to PINCTRL_RENESAS. Rename the git branch in MAINTAINERS, too, for consistency. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://lore.kernel.org/r/20200909131534.12897-3-geert+renesas@glider.be

2020-09-15pinctrl: rza1: Switch to using "output-enable"Geert Uytterhoeven
For pins requiring software driven IO output operations, the RZ/A1 Pin Controller uses either the "output-high" or "output-low" DT property to enable the corresponding output buffer. The actual line value doesn't matter, as it is ignored. Commit 425562429d4f3b13 ("pinctrl: generic: Add output-enable property") introduced a new DT property for this specific use case. Update the RZ/A1 Pin Controller DT bindings and driver to use this new property instead. Preserve backwards compatibility with old DTBs in the driver, as this comes at a very small cost. Notes: - The DT binding examples already used the new property, - There are no upstream users of the old properties.

2020-09-12pinctrl: devicetree: Keep deferring even on timeoutThierry Reding
driver_deferred_probe_check_state() may return -ETIMEDOUT instead of -EPROBE_DEFER after all built-in drivers have been probed. This can cause issues for built-in drivers that depend on resources provided by loadable modules. One such case happens on Tegra where I2C controllers are used during early boot to set up the system PMIC, so the I2C driver needs to be a built-in driver. At the same time, some instances of the I2C controller depend on the DPAUX hardware for pinmuxing. Since the DPAUX is handled by the display driver, which is usually not built-in, the pin control states will not become available until after the root filesystem has been mounted and the display driver loaded from it.

2020-09-07pinctrl: cherryview: Preserve CHV_PADCTRL1_INVRXTX_TXDATA flag on GPIOsHans de Goede
One some devices the GPIO should output the inverted value from what device-drivers / ACPI code expects. The reason for this is unknown, perhaps these systems use an external buffer chip on the GPIO which inverts the signal. The BIOS makes this work by setting the CHV_PADCTRL1_INVRXTX_TXDATA flag. Before this commit we would unconditionally clear all INVRXTX flags, including the CHV_PADCTRL1_INVRXTX_TXDATA flag when a GPIO is requested by a driver (from chv_gpio_request_enable()). This breaks systems using this setup. Specifically it is causing problems for systems with a goodix touchscreen, where the BIOS sets the INVRXTX_TXDATA flag on the GPIO used for the touchscreen's reset pin. The goodix touchscreen driver by defaults configures this pin as input (relying on the pull-up to keep it high), but the clearing of the INVRXTX_TXDATA flag done by chv_gpio_request_enable() causes it to be driven low for a brief time before the GPIO gets set to input mode. This causes the touchscreen controller to get reset. On most CHT devs with this touchscreen this leads to: [ 31.596534] Goodix-TS i2c-GDIX1001:00: i2c test failed attempt 1: -121 The driver retries this though and then everything is fine. But during reset the touchscreen uses its interrupt pin as bootstrap to determine which i2c address to use and on the Acer One S1003 the spurious reset caused by the clearing of the INVRXTX_TXDATA flag causes the controller to come back up again on the wrong i2c address, breaking things. This commit fixes both the -121 errors, as well as the total breakage on the Acer One S1003, by making chv_gpio_clear_triggering() not clear the INVRXTX_TXDATA flag if the pin is already configured as a GPIO. Note that chv_pinmux_set_mux() does still unconditionally clear the flag, so this only affects GPIO usage.
