2022-02-25Merge tag 'samsung-dt-pinctrl-5.18' of ↵Arnd Bergmann1-22/+22
git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into arm/dt Samsung pinctrl DTS and driver changes for v5.18 Conversion of Samsung pinctrl bindings to dtschema followed up with alignment of DTS files to the dtschema. The entire work consists of three parts but everything should be merged at once to avoid dtschema check errors: 1. Samsung pinctrl driver change necessary to accept new DTS (driver depends on node names and this has to be adjusted because of dtschema). 2. Conversion to dtschema which brings requirement of different naming of the GPIO nodes. 3. DTS commits depending on driver (1) above, which convert all GPIO pin bank names to new naming, required by dtschema. This also includes few cleanups around DTS which are here to avoid any merge conflicts. The Samsung pinctrl driver changes are backwards compatible. However the DTS changes (renaming nodes) could cause problems in out-of-tree or other project implementations of the driver. * tag 'samsung-dt-pinctrl-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: (28 commits) arm64: dts: exynos: use dedicated wake-up pinctrl compatible in ExynosAutov9 ARM: dts: s5pv210: align pinctrl with dtschema ARM: dts: s3c64xx: align pinctrl with dtschema ARM: dts: s3c24xx: align pinctrl with dtschema arm64: dts: exynos: align pinctrl with dtschema in ExynosAutov9 arm64: dts: exynos: align pinctrl with dtschema in Exynos7 arm64: dts: exynos: align pinctrl with dtschema in Exynos5433 ARM: dts: exynos: align pinctrl with dtschema in Exynos542x/5800 ARM: dts: exynos: align pinctrl with dtschema in Exynos5410 ARM: dts: exynos: align pinctrl with dtschema in Exynos5260 ARM: dts: exynos: align pinctrl with dtschema in Exynos5250 ARM: dts: exynos: align pinctrl with dtschema in Exynos4412 ARM: dts: exynos: align pinctrl with dtschema in Exynos4210 ARM: dts: exynos: align pinctrl with dtschema in Exynos3250 ARM: dts: s3c64xx: drop unneeded pinctrl wake-up interrupt mapping ARM: dts: exynos: simplify PMIC DVS pin configuration in Peach Pi ARM: dts: exynos: override pins by label in Peach Pi ARM: dts: exynos: simplify PMIC DVS pin configuration in Peach Pit ARM: dts: exynos: override pins by label in Peach Pit ARM: dts: exynos: simplify PMIC DVS pin configuration in Odroid XU ...

The RTC on Maxim max77686 PMIC can wakeup the system from suspend to RAM. Add a generic property for this. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com> Link: https://lore.kernel.org/r/20210420164943.11152-7-krzysztof.kozlowski@canonical.com
2021-03-07ARM: dts: exynos: correct PMIC interrupt trigger level on P4 Note familyKrzysztof Kozlowski1-1/+1
The Maxim PMIC datasheets describe the interrupt line as active low with a requirement of acknowledge from the CPU. Without specifying the interrupt type in Devicetree, kernel might apply some fixed configuration, not necessarily working for this hardware. Additionally, the interrupt line is shared so using level sensitive interrupt is here especially important to avoid races.

The Maxim fuel gauge datasheets describe the interrupt line as active low with a requirement of acknowledge from the CPU. The falling edge interrupt will mostly work but it's not correct.

2020-11-22ARM: dts: exynos: switch Atmel mxt reset GPIO to active low on P4 NoteMartin Jücker1-1/+1
The reset GPIO logic of the Atmel maxtouch driver was changed to be active low at around the same time P4 Note device tree was accepted into the kernel. Adjust the configuration so that the touchscreen is in a usable state.
