2021-08-13pinctrl: renesas: Add RZ/G2L pin and gpio controller driverLad Prabhakar3-0/+1187
Add support for pin and gpio controller driver for RZ/G2L SoC. Based on a patch in the BSP by Hien Huynh <hien.huynh.px@renesas.com>.

2021-07-27pinctrl: renesas: Fix pin control matching on R-Car H3e-2GGeert Uytterhoeven2-19/+14
As R-Car H3 ES1.x (R8A77950) and R-Car ES2.0+ (R8A77951) use the same compatible value, the pin control driver relies on soc_device_match() with soc_id = "r8a7795" and the (non)matching of revision = "ES1.*" to match with and distinguish between the two SoC variants. The corresponding entries in the normal of_match_table are present only to make the optional sanity checks work. The R-Car H3e-2G (R8A779M1) SoC is a different grading of the R-Car H3 ES3.0 (R8A77951) SoC. It uses the same compatible values for individual devices, but has an additional compatible value for the root node. When running on an R-Car H3e-2G SoC, soc_device_match() with soc_id = "r8a7795" does not return a match. Hence the pin control driver falls back to the normal of_match_table, and, as the R8A77950 entry is listed first, incorrectly uses the sub-driver for R-Car H3 ES1.x. Fix this by moving the entry for R8A77951 before the entry for R8A77950. Simplify sh_pfc_quirk_match() to only handle R-Car H3 ES1,x, as R-Car H3 ES2.0+ can now be matched using the normal of_match_table as well.

2021-07-13pinctrl: renesas: r8a77995: Add bias pinconf supportGeert Uytterhoeven3-9/+316
Implement support for pull-up (most pins, excl. DU_DOTCLKIN0) and pull-down (most pins, excl. JTAG) handling for the R-Car D3 SoC, using some parts from the common R-Car bias handling, which requires making rcar_pin_to_bias_reg() public. R-Car D3 needs special handling for the NFRE# (GP_3_0) and NFWE# (GP_3_1) pins. Unlike all other pins, they are controlled by different bits in the LSI pin pull-up/down control register (PUD2) than in the LSI pin pull-enable register (PUEN2).

When disabling pin bias, there is no need to touch the LSI pin pull-up/down control register (PUDn), which selects between pull-up and pull-down. Just disabling the pull-up/down function through the LSI pin pull-enable register (PUENn) is sufficient.

2021-03-24pinctrl: renesas: Add support for R-Car SoCs with pull-down only pinsGeert Uytterhoeven2-19/+34
Currently, the common R-Car bias handling supports pin controllers with either: 1. Separate pin Pull-Enable (PUEN) and pin Pull-Up/Down control (PUD) registers, for controlling both pin pull-up and pin pull-down, 2. A single pin Pull-Up control register (PUPR), for controlling pin pull-up. Add support for a variant of #2, where some bits in the single pin Pull-Up control register (PUPR) control pin pull-down instead of pin pull-up. This is the case for the "ASEBRK#/ACK" pin on R-Car M2-W, M2-N, and E2, and the "ACK" pin on RZ/G1M, RZ/G1N, RZ/G1E, and RZ/G1C. To describe such a register, SoC-specific drivers need to provide two instances of pinmux_bias_reg: a first one with the puen field filled in, listing pins with pull-up functionality, and a second one with the pud field filled in, listing pins with pull-down functionality.

2021-01-14pinctrl: renesas: Add I/O voltage level flagUlrich Hecht2-2/+23
This patch adds config macros describing the voltage levels available on a pin. The current default (3.3V/1.8V) maps to zero to avoid having to change existing PFC implementations.

2021-01-14pinctrl: renesas: Implement unlock register masksUlrich Hecht2-11/+19
The V3U SoC has several unlock registers, one per register group. They reside at offset zero in each 0x200 bytes-sized block. To avoid adding yet another table to the PFC implementation, this patch adds the option to specify an address mask instead of the fixed address in sh_pfc_soc_info::unlock_reg.

2021-01-12pinctrl: renesas: checker: Restrict checks to Renesas platformsGeert Uytterhoeven1-0/+4
When DEBUG is defined (e.g. if CONFIG_DEBUG_PINCTRL=y), the Renesas pin control driver runs sanity checks against the pin control tables. This may cause lots of output on the console, and can be annoying in ARM multi-platform kernels. Fix this by only running the checks when running on SuperH, or on a DT platform supported by the Renesas pin controller driver.
