[PATCH v3 2/3] pinctrl: add driver for Amlogic Meson SoCs

[Beniamino Galvani <b.galvani@xxxxxxxxx>]

This is a driver for the pinmux and GPIO controller available in
Amlogic Meson SoCs. At the moment it only supports Meson8 devices,
however other SoC families like Meson6 and Meson8b (the Cortex-A5
variant) appear to be similar, with just different sets of banks and
registers.

GPIO interrupts are not supported at the moment due to lack of
documentation.

+/*
+ * The available pins are organized in banks (A,B,C,D,E,X,Y,Z,AO,
+ * BOOT,CARD for meson6 and X,Y,DV,H,Z,AO,BOOT,CARD for meson8) and
+ * each bank has a variable number of pins.
+ *
+ * The AO bank is special because it belongs to the Always-On power
+ * domain which can't be powered off; the bank also uses a set of
+ * registers different from the other banks.
+ *
+ * For each of the two power domains (regular and always-on) there are
+ * 4 different register ranges that control the following properties
+ * of the pins:
+ *  1) pin muxing
+ *  2) pull enable/disable
+ *  3) pull up/down
+ *  4) GPIO direction, output value, input value
+ *
+ * In some cases the register ranges for pull enable and pull
+ * direction are the same and thus there are only 3 register ranges.
+ *
+ * Every pinmux group can be enabled by a specific bit in the first
+ * register range of the domain; when all groups for a given pin are
+ * disabled the pin acts as a GPIO.
+ *
+ * For the pull and GPIO configuration every bank uses a contiguous
+ * set of bits in the register sets described above; the same register
+ * can be shared by more banks with different offsets.
+ *
+ * In addition to this there are some registers shared between all
+ * banks that control the IRQ functionality. This feature is not
+ * supported at the moment by the driver.
