2022-02-22pinctrl: renesas: Add generic support for resizable busesGeert Uytterhoeven
The VIN_DATA_PIN_GROUP() macro and vin_data{12,16,} unions are used to define multiple VIN data groups with different numbers of lanes, while referring to a single array of data pins, thus saving memory. However, the same feature would be useful for other resizable buses, like MMC, SDHI, QSPI, LCD, BSC, ... Rework the mechanism for generic use: - Use the new SH_PFC_PIN_GROUP_SUBSET() helper to remove the need for bus-specific unions, - Rename VIN_DATA_PIN_GROUP() to BUS_DATA_PIN_GROUP(), - Rename the macro parameters to better reflect their purposes, - Move the macro up, where it belongs. Update all individual pin control drivers for the above changes.

2022-02-22pinctrl: renesas: Add generic support for pin group subsetsGeert Uytterhoeven
It is fairly common for the pins in a pin group to be a subset of the pins in another pin group. Add a macro for defining a pin group that refers to a subset of an array of pins. This allows pin groups to share pin data, and thus save memory.

The second video-in channel on RZ/G1C has only 12 data lanes, but the pin control driver uses the vin_data union, which is meant for 24 data lanes, thus wasting space.

If some bits in a pin Pull-Up control register (PUPR) control pin pull-down instead of pin pull-up, there are two pinmux_bias_reg entries: 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. On encountering the second entry, where puen is NULL, the for-loop terminates early, causing the remaining bias registers not to be saved/restored during PSCI system suspend. Fortunately this does not trigger on any supported system yet, as PSCI is only used on R-Car Gen3 and RZ/G2 systems, which all have separate pin Pull-Enable (PUEN) and pin Pull-Up/Down control (PUD) registers. Avoid this ever becoming a problem by treating pinmux_bias_reg.puen and pinmux_bias_reg.pud the same. Note that a register controlling both pull-up and pull-down pins would be saved and restored twice, which is harmless.

2021-07-27pinctrl: renesas: Fix pin control matching on R-Car H3e-2GGeert Uytterhoeven
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 Uytterhoeven
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).

2021-07-13pinctrl: renesas: rcar: Avoid changing PUDn when disabling biasGeert Uytterhoeven
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.
