2024-01-24pinctrl: exynos: Add pinctrl support for Exynos850Sam Protsenko
Add pinctrl support for Exynos850 SoC. It was mostly extracted from corresponding Linux kernel code [1]. Power down modes and external interrupt data were removed while converting the code for U-Boot, but everything else was kept almost unchanged.

2024-01-16pinctrl: qcom: make compatible with linux DTsCaleb Connolly
The pinctrl and GPIO drivers are currently heavily incompatible with upstream. Most Qualcomm pinctrl blocks feature "tiles" of pins, each at it's own address. Introduce support for these by allowing the soc driver to specify per-pin register offsets similarly to the Linux driver. Adjust the GPIO driver to handle these too, and finally enable support for all pins with the same numbering as used in Linux.

2024-01-09pinctrl: exynos: Refactor handling the pin related dt propertiesSam Protsenko
All pin related dt properties (pin-function, pin-pud and pin-drv) are handled in a very similar way. Get rid of that code duplication by extracting the corresponding data knowledge into an actual data structure (array), and then just iterating over it. No functional change, it's a refactoring commit. Signed-off-by: Sam Protsenko <[email protected]> Signed-off-by: Minkyu Kang <[email protected]>
2024-01-09pinctrl: exynos: Support different register types in pin banksSam Protsenko
Get rid of hard-coded register offsets and widths. Instead provide a way for pinctrl drivers to specify different pin bank register offsets and widths. This in turn makes it possible to add support for new SoCs that have registers with offset/width values different than generic ones already available in pinctrl-exynos driver. Offset constants (now unused in pinctrl-exynos.c) are moved to pinctrl-exynos7420 driver, which is the single user of those constants. The design of this patch follows Linux kernel pinctrl-exynos driver design, in terms of added data structures and types. This patch doesn't add support for any new SoCs and shouldn't introduce any functional changes. Signed-off-by: Sam Protsenko <[email protected]> Signed-off-by: Minkyu Kang <[email protected]>
2024-01-09pinctrl: exynos: Rework pin_to_bank_base() to obtain data by nameSam Protsenko
Rework pin_to_bank_base() function to obtain bank data structure by bank name instead of getting bank base address by pin name, and rename it to get_bank() to reflect this change. This in turn leads to the extraction of parse_pin(), so the caller has to use it before calling get_bank(). No functional change. This is a refactoring commit which prepares pinctrl driver code for handling different sizes of register fields, which will be added next.

2023-10-22sunxi: add Allwinner R528/T113 SoC supportAndre Przywara
This adds the remaining code bits to teach U-Boot about Allwinner's newest SoC generation. This was introduced with the RISC-V based Allwinner D1 SoC, which actually shares a die with the ARM cores versions called R528 (BGA, without DRAM) and T113s (QFP, with embedded DRAM). This adds the new Kconfig stanza, using the two newly introduced symbols for the new SoC generation and pincontroller. It also adds the new symbols to the relavent code places, to set all the hardcoded bits directly. We need one DT override: The ARM core version of the DT specifies the CPUX watchdog as "reserved", which means it won't be recognised by U-Boot. Override this in our generic sunxi-u-boot.dtsi, to let U-Boot pick up this watchdog, so that the generic reset driver will work. Signed-off-by: Andre Przywara <[email protected]>
2023-10-22pinctrl: sunxi: add Allwinner D1 pinctrl descriptionAndre Przywara
Apart from using the new pinctrl MMIO register layout, the Allwinner D1 and related SoCs still need to usual set of mux values hardcoded in U-Boot's pinctrl driver. Add the values we need so far to this list, so that DM based drivers will just work without further ado. Signed-off-by: Andre Przywara <[email protected]>
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 <[email protected]> Tested-by: Samuel Holland <[email protected]>
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 pinctrl features of the GPIO/PFC module in the Renesas RZ/G2L (R9A07G044) SoC. A multi-function `rzg2l-pfc` driver is defined for UCLASS_NOP, which binds the `rzg2l-pfc-pinctrl` UCLASS_PINCTRL driver dynamically. We also define common macros and functions for the PFC in <renesas/rzg2l-pfc.h>. This makes it easy to add an additional UCLASS_GPIO driver for the GPIO functionality of this module in a follow-up patch.

2023-10-01pinctrl: renesas: Add support for 1.8V/2.5V I/O voltage levelsMarek Vasut
Currently, the Renesas pin control driver supports pins that can switch their I/O voltage levels between either 1.8V and 3.3V, or between 2.5V and 3.3V. However, some SoCs have pins that can switch between 1.8V and 2.5V. Add support for this by replacing the separate SH_PFC_PIN_CFG_IO_VOLTAGE capability and voltage level flags by a 2-bit field, to cover three possible I/O voltage switching options.
