2024-03-14gpio: rockchip: Use gpio alias id as gpio bank idJonas Karlman
The U-Boot driver try to base the gpio bank id on the gpio-ranges prop and fall back to base the bank id on the node name. However, the linux driver try to base the bank id on the gpio alias id and fall back on node order. This can cause issues when SoC DT is synced from linux and gpioX@ nodes has been renamed to gpio@ and gpio-ranges or a SoC specific alias has not been assigned. Try to use the gpio alias id as first fallback when a gpio-ranges prop is missing to ease sync of updated SoC DT. Keep the current fallback on node name as a third fallback to not affect any existing unsynced DT.

2024-03-01pinctrl: qcom: stub support for special GPIOsCaleb Connolly
Most platforms have a handful of "special" GPIOs, like the MMC clock/data lanes, UFS reset, etc. These don't follow the usual naming scheme of "gpioX" and also have unique capabilities and registers. We can get away without supporting them all for now, but DT compatibility is still an issue. Add support for allowing these to be specified after the other pins, and make all pinmux/pinconf calls for them nop.

Introduce a basic pinctrl driver for the SPMI PMIC GPIOs. This is necessary to make proper use of upstream DT bindings specifically on the dragonboard410c where they're used to switch between USB host and device modes. Only support for driving the pins as output low or high is enabled for now. To minimise duplicated code and allow for sharing common DT data, the pinctrl driver is initialised as a child of the existing GPIO driver.

Some platforms hard reset when attempting to configure PMIC GPIOs. Add support for quirks specified in match data with a single quirk to skip this configuration. We rely on the GPIO already be configured correctly, which is always the case for volume up (the only current user of these GPIOs). This is not expected behaviour but appears to be due to a U-Boot specific bug. This quirk at least allows for the volume buttons to be used on platforms where this bug is apparent.

2023-10-22pinctrl: sunxi: add new D1 pinctrl supportAndre Przywara
For the first time since at least the Allwinner A10 SoCs, the D1 (and related cores) use a new pincontroller MMIO register layout, so we cannot use our hardcoded, fixed offsets anymore. Ideally this would all be handled by devicetree and DM drivers, but for the DT-less SPL we still need the legacy interfaces. Add a new Kconfig symbol to differenciate between the two generations of pincontrollers, and just use that to just switch some basic symbols. The rest is already abstracted enough, so works out of the box.

2023-10-22pinctrl: sunxi: remove GPIO_EXTRA_HEADERAndre Przywara
U-Boot's generic GPIO_EXTRA_HEADER is a convenience symbol to allow code to more easily include platform specific GPIO headers. This should not be needed in a DM world anymore, since the generic GPIO framework handles that nicely. For Allwinner boards we still need to deal with non-DM GPIO in the SPL, but this should become the exception, not the rule. Make this more obvious by removing the definition of GPIO_EXTRA_HEADER, and just force every legacy user of platform specific GPIO to include the new sunxi_gpio.h header explicitly. Everyone doing so should feel ashamed and should find a way to avoid it from now on. Signed-off-by: Andre Przywara <andre.przywara@arm.com> Tested-by: Samuel Holland <samuel@sholland.org>
2023-10-22pinctrl: sunxi: remove struct sunxi_gpioAndre Przywara
So far every Allwinner SoC used the same basic pincontroller/GPIO register frame, and just differed by the number of implemented banks and pins, plus some special functionality from time to time. However the D1 and successors use a slightly different pinctrl register layout. Use that opportunity to drop "struct sunxi_gpio", that described that MMIO frame in a C struct. That approach is somewhat frowned upon in the Linux world and rarely used there, though still popular with U-Boot. Switching from a C struct to a "base address plus offset" approach allows to switch between the two models more dynamically, without reverting to preprocessor macros and #ifdef's. Model the pinctrl MMIO register frame in the usual "base address + offset" way, and replace a hard-to-parse CPP macro with a more readable static function. All the users get converted over. There are no functional changes at this point, it just prepares the stages for the D1 and friends.

This driver adds support for the gpio features of the GPIO/PFC module in the Renesas RZ/G2L (R9A07G044) SoC. The new `rzg2l-pfc-gpio` driver is bound to the same device tree node as the `rzg2l-pfc-pinctrl` driver as the same hardware block provides both GPIO and pin multiplexing features.

A follow-up to commit 842fb5de424e ("drivers: use devfdt_get_addr_size_index_ptr when cast to pointer") and commit 320a1938b6f7 ("drivers: use devfdt_get_addr_index_ptr when cast to pointer"). In addition to using the *_ptr variants of these functions where the address is cast to a pointer, this also changes devfdt_get_addr_*() to dev_read_addr_*() in a few places. Some variable and field types are changed from fdt_addr_t or phys_addr_t to void* where the cast was happening later. This patch fixes a number of compile warnings when building a 32bit U-Boot with CONFIG_PHYS_64BIT=y. In some places, it also fixes error handling where the return value of dev_read_addr() etc. was checked for NULL instead of FDT_ADDR_T_NONE.
