| * pinctrl: imx: fix scu link errorsAnders Roxell2019-03-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently PINCTRL_IMX8QM and PINCTRL_IMX8QXP will select PINCTRL_IMX_SCU. However, PINCTRL_IMX_SCU may not be valid due to it depends on IMX_MBOX.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's reasonable to expect that people turn to the "gpio" debugfs file to first and foremost learn about the direction and value of a gpio, and second to that about it's pinconf. So reorder the value so each line reads: gpioN: direction value ... This also makes it consistent with the TLMM pinctrl driver's output in the same dump.

| * | pinctrl: sunxi: Support I/O bias voltage setting on A80Chen-Yu Tsai2019-02-114-0/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The A80 SoC has configuration registers for I/O bias voltage. Incorrect settings would make the affected peripherals inoperable in some cases, such as Ethernet RGMII signals biased at 2.5V with the settings still at 3.3V. However low speed signals such as MDIO on the same group of pins seem to be unaffected. Previously there was no way to know what the actual voltage used was, short of hard-coding a value in the device tree. With the new pin bank regulator supply support in place, the driver can now query the regulator for its voltage, and if it's valid (as opposed to being the dummy regulator), set the bias voltage setting accordingly. Add a quirk to denote the presence of the configuration registers, and a function to set the correct setting based on the voltage read back from the regulator. This is only done when the regulator is first acquired and enabled. While it would be nice to have a notifier on the regulator so that when the voltage changes, the driver can update the setting, in practice no board currently supports dynamic changing of the I/O voltages.

| | * | pinctrl: sh-pfc: r8a77965: Replace DU_DOTCLKIN2 by DU_DOTCLKIN3Geert Uytterhoeven2019-01-211-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike R-Car M3-W, R-Car M3-N does not have DU_DOTCLKIN2, but the corresponding pin carries the DU_DOTCLKIN3 signal. Correct all references to DU_DOTCLKIN2 to fix this. This change does not have any runtime effect, as it only changes an internal enum name, and a comment.

Increase consistency with other SoCs by making R-Car M2-W and M2-N, and RZ/G1M and RZ/G1N, use the recently added optional "version" argument of the VIN_DATA_PIN_GROUP() macro. Note that this breaks backwards compatibility with existing DTBs, but there are no upstream users of the "vin1_b_*" names.
