About Intel Keem Bay: ------------------- Intel Keem Bay is a computer vision AI accelerator SoC based on ARM CPU. Documentation of Keem Bay: Documentation/vpu/vpu-stack-overview.rst. Pinctrl IP: ---------- The SoC has a customised pinmux controller IP which controls pin multiplexing and configuration. Keem Bay pinctrl IP is not based on and have nothing in common with the existing pinctrl drivers. The registers used are incompatible with the existing drivers, so it requires a new driver. Add pinctrl driver to enable pin control support in the Intel Keem Bay SoC. Co-developed-by:

Chen-Yu Tsai authored
The original binding submission for MT8195 pinctrl described the possible drive strength values in micro-amps in its description, but then proceeded to list register values in its device tree binding constraints. However, the macros used with the Mediatek pinctrl bindings directly specify the drive strength in micro-amps, instead of hardware register values. The current driver implementation in Linux does convert the value from micro-amps to hardware register values. This implementation is also used with MT7622 and MT8183, which use real world values in their device trees. Given the above, it was likely an oversight to use the raw register values in the binding. Correct the values in the binding. Also drop the description since the binding combined with its parent, pinctrl/pincfg.yaml, the binding is now self-describing.

1.Rename the original "dmicx" ABIs to "dmic-ifx", since these devices have only one DMIC module which has multiple input interfaces. The original naming is easy to make users mistakenly think that the device has multiple dmic modules. Currently, in the mainline, no other devicetree out there is using the "sfc" ABI, so we should be able to replace it safely. 2.Rename the original "ssix-ce0" ABIs to "ssix-ce", since the X2000 have only one ce pin. The original naming is easy to make users mistakenly think that the device has multiple ce pins. Currently, in the mainline, no other devicetree out there is using the "ssix-ce0" ABIs, so we should be able to replace it safely. 3.Split the original "sfc" ABI into "sfc-data", "sfc-ce", "sfc-clk" to increase the flexibility when configuring the pins. Currently, in the mainline, no other devicetree out there is using the "sfc" ABI, so we should be able to replace it safely. 4.There is more than one compatible string in the match table, so renaming "ingenic_xxxx_of_match[]" to "ingenic_xxxx_of_matches" is more reasonable, and remove the unnecessary commas in "ingenic_gpio_of_matches[]" to reduce code size as much as possible.

Casting a small array of u8 to an unsigned long is *never* OK: - it does funny thing when the array size is less than that of a long, as it accesses random places in the stack - it makes everything even more fun with a BE kernel Fix this by building the unsigned long used as a bitmap byte by byte, in a way that works across endianess and has no undefined behaviours. An extra BUILD_BUG_ON() catches the unlikely case where the array would be larger than a single unsigned long. Fixes: 1490d9f8 ("pinctrl: Add STMFX GPIO expander Pinctrl/GPIO driver") Signed-off-by:

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. Signed-off-by:
