* arm64: dts: exynos: move XTCXO clock frequency to board in Exynos Auto v9Krzysztof Kozlowski2022-05-042-1/+4
| | | | | | | | | | | The external oscillator - XTCXO - is an input to the SoC. It is defined in the Exynos Auto v9 SoC DTSI, because all boards will provide it and clock controller bindings expect it, however the actual frequency of the clock should be determined by the board.

* arm64: dts: exynos: add a specific compatible to MCTKrzysztof Kozlowski2022-04-042-2/+4
| | | | | | | | | | | One compatible is used for the Multi-Core Timer on most of the Samsung Exynos SoCs, which is correct but not specific enough. These MCT blocks have different number of interrupts, so add a second specific compatible to Exynos5433 and Exynos850.

| | | | | | | | | | | | | The aliases for typical blocks which are disabled by default in DTSI (like I2C, UART and MMC) should be defined in the board DTS. The board should add aliases only for enabled blocks according to its specific order. On Exynos850, move aliases of enabled blocks to E850-96 board and remove unused ones.

Also they expected to have exactly one pin controller capable of external wake-up interrupts. It seems however that newer ARMv8 Exynos SoC like Exynos850 and ExynosAutov9 have differences: 1. No multiplexed external wake-up interrupt, only direct, 2. More than one pin controller capable of external wake-up interrupts.

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 ...

| | | | | | | | | | | | | | | | | It's not possible to reboot or poweroff Exynos7420 using PSCI. Instead we need to use syscon reboot/poweroff drivers, like it's done for other Exynos SoCs. This was confirmed by checking vendor source and testing it on Samsung Galaxy S6 device based on this SoC. To be able to use custom restart/poweroff handlers instead of PSCI functions, we need to correct psci compatible. This also requires us to provide function ids for CPU_ON and CPU_OFF.
