* Marvell Armada 370 SoC pinctrl driver for mpp
Please refer to marvell,mvebu-pinctrl.txt in this directory for common binding
part and usage.
Required properties:
- compatible: "marvell,88f6710-pinctrl"
devicetree: bindings: update MVEBU pinctrl binding documentation Dove pinctrl binding now requires three different reg properties. This updates corresponding binding and example accordingly. While at it, also document reg property as required for the other MVEBU SoC pinctrl nodes. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>

pinctrl: mvebu: armada-370: align VDD cpu-pd pin naming with datasheet For consistency with the datasheet, this commit renames the VDD function of the MPP4 pin. While this changes the DT compatibility, it is not considered to be a problem since this pin is unlikely to be used for anything but debugging purposes.

pinctrl: mvebu: armada-370: align spi1 clock pin naming Across all SoCs, even on Armada 370 for SPI0, the clock pin uses the 'sck' subname and not 'clk', so this commit adjusts the code and documentation accordingly. Since this commit only changes the subname, DT backward compatibility is not affected.

pinctrl: mvebu: armada-{370,375,38x,39x,xp}: normalize TDM pins This commit normalizes the naming of the TDM pins accross the different Marvell SoCs. Mainly it consists in: * Removing the 'n' from signal names: 'intn' becomes 'int' and 'rstn' becomes 'rst' * Renaming the main name 'tdm2c' to 'tdm' on Armada 38x. * Change the main name 'tdm-1' to 'tdm' for one of the pins of the Armada XP The last two changes affect DT compatibility, but since the TDM interface is nowhere near being supported in mainline, it should not be considered to be a serious problem at this point.

pinctrl: mvebu: armada-{370,375,38x,39x}: normalize dev pins This commit modifies the definition of the Device Bus interface pins to be consistent accross SoCs. Especially, it removes the 'n' indicators that we don't encode in the subnames of pins: 'dev(wen0)' becomes 'dev(we0)' 'dev(wen1)' becomes 'dev(we1)' 'dev(oen)' becomes 'dev(oe)' etc. In addition, it fixes the Armada 375 DT binding documentation, which forgot to document the 'dev' function for MPP46, MPP57 and MPP63. Since only the subnames are changed, this commit does not affect DT compatibility.

ARM: dts: armada-370: Update the mpp63 function in the device tree on Armada 370 Since the commit a526973e0291 ("pinctrl: mvebu: Fix mapping of pin 63 (gpo -> gpio)"), the mpp63 is no more declared as a GPO but is a GPIO. Even if in the datasheet this pin is described as GPO, the experience of the D-Link DNS-327L board shows that it can be used as a GPIO. This commits generated warnings for the board using this pin as gpo, with this patch the dts are fixed by using the new function (gpio) instead of the old one.
