pinctrl: sunxi: add support for the Allwinner H6 main pin controller The Allwinner H6 SoC has two pin controllers, one main controller (called CPUX-PORT in user manual) and one controller in CPUs power domain (called CPUS-PORT in user manual). This commit introduces support for the main pin controller on H6. The pin bank A and B are not wired out and hidden from the SoC's documents, however it's shown that the "ATE" (an AC200 chip co-packaged with the H6 die) is connected to the main SoC die via these pin banks. The information about these banks is just copied from the BSP pinctrl driver, but re-formatted to fit the mainline pinctrl driver format. The GPIO functions are dropped, as they're impossible to use -- except a GPIO&IRQ only pin (PB20) which might be the IRQ of ATE.

pinctrl: sunxi: Correct number of IRQ banks on H6 main pin controller The H6 main pin controller has four banks of interrupt-triggering pins. The driver as originally submitted only specified three, but had pin descriptions referencing a fourth bank. This results in a out-of-bounds access into .irq_array of struct sunxi_pinctrl. This however did not result in a crash until v4.20, with commit a66d972465d1 ("devres: Align data[] to ARCH_KMALLOC_MINALIGN"), which changed the alignment of memory region returned by devm_kcalloc(). The increase likely moved the out-of-bounds access into the next, unmapped page.

pinctrl: sunxi: add support for the Allwinner H6 main pin controller The Allwinner H6 SoC has two pin controllers, one main controller (called CPUX-PORT in user manual) and one controller in CPUs power domain (called CPUS-PORT in user manual). This commit introduces support for the main pin controller on H6. The pin bank A and B are not wired out and hidden from the SoC's documents, however it's shown that the "ATE" (an AC200 chip co-packaged with the H6 die) is connected to the main SoC die via these pin banks. The information about these banks is just copied from the BSP pinctrl driver, but re-formatted to fit the mainline pinctrl driver format. The GPIO functions are dropped, as they're impossible to use -- except a GPIO&IRQ only pin (PB20) which might be the IRQ of ATE.

pinctrl: sunxi: Support I/O bias voltage setting on H6 H6 SoC has a "pio group withstand voltage mode" register (datasheet description), that needs to be used to select either 1.8V or 3.3V I/O mode, based on what voltage is powering the respective pin banks and is thus used for I/O signals. Add support for configuring this register according to the voltage of the pin bank regulator (if enabled). This is similar to the support for I/O bias voltage setting patch for A80 and the same concerns apply.
