[RFC PATCH v1 4/9] pinctrl: renesas: add R906G032 driver

Ralph Siemsen
2022-08-09T13:01:41Z

Pinctrl/pinconf driver for Renesas RZ/N1 (R906G032) SoC.

This is quite rudimentary right now, and only supports applying a
default pin configuration as specified by the device tree.

TODO:

- iterate over subnodes, so we can handle groups of pins with
different bias/strength settings

- use the regmap_update_bits for level1/level2 register updates
--> does not exist for regmap_ranges, consider adding?

+ * The hardware manual describes two levels of multiplexing, but it's more

+ * the multiplexing for Ethernet MDIO signals.
+ *
+ * Level 1 functions go from 0 to 9, with level 1 function '15' (0xf) specifying
+ * that level 2 functions are used instead. Level 2 has a lot more options,
+ * going from 0 to 61. Level 3 allows selection of MDIO functions which can be
+ * floating, or one of seven internal peripherals. Unfortunately, there are two
+ * level 2 functions that can select MDIO, and two MDIO channels so we have four
+ * sets of level 3 functions.
+ *
+ * For this driver, we've compounded the numbers together, so:
+ * 0 to 9 is level 1
+ * 10 to 71 is 10 + level 2 number
+ * 72 to 79 is 72 + MDIO0 source for level 2 MDIO function.

+ * 88 to 95 is 88 + MDIO1 source for level 2 MDIO function.
+ * 96 to 103 is 96 + MDIO1 source for level 2 MDIO_E1 function.
