* ARM: dts: sun4i: Enable HDMI support on some A10 devicesChen-Yu Tsai2017-10-181-0/+25
| | | | | | | | | | | | | | Various A10-based development boards have standard HDMI connectors wired to the dedicated HDMI pins on the SoC. Enable the display pipeline and HDMI output on boards I have or have access to schematics: - Cubieboard - Olimex A10-OLinuXino-LIME Signed-off-by: Chen-Yu Tsai <wens@csie.org> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com>
* ARM: dts: sun4i: Remove underscores from nodes namesMaxime Ripard2017-10-131-3/+3
| | | | | | | | | | | | | Some GPIO pinctrl nodes cannot be easily removed, because they would also change the pin configuration, for example to add a pull resistor or change the current delivered by the pin. Those nodes still have underscores and unit-addresses in their node names in our DTs, so adjust their name to remove the warnings. Use that occasion to also fix some poorly chosen node-names.

* ARM: dts: sun4i: Provide default muxing for relevant controllersMaxime Ripard2017-10-131-8/+0
| | | | | | | | | The I2C's, MMC0 and EMAC controllers have only one muxing option in the SoC. In such a case, we can just move the muxing into the DTSI, and remove it from the DTS. Acked-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
* ARM: dts: sun4i: Change pinctrl nodes to avoid warningMaxime Ripard2017-10-131-5/+5
| | | | | | | | | | | | All our pinctrl nodes were using a node name convention with a unit-address to differentiate the different muxing options. However, since those nodes didn't have a reg property, they were generating warnings in DTC. In order to accomodate for this, convert the old nodes to the syntax we've been using for the new SoCs, including removing the letter suffix of the node labels to the bank of those pins to make things more readable.

* ARM: dts: sun4i: Remove all useless pinctrl nodesMaxime Ripard2017-10-061-6/+0
| | | | | | | | | The gpio pinctrl nodes are redundant and as such useless most of the times. Since they will also generate warnings in DTC, we can simply remove most of them. Acked-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
* ARM: sunxi: Drop mmc0_cd_pin_reference_design pinmux settingChen-Yu Tsai2017-05-141-1/+1
| | | | | | | | | | As part of our effort to move pinctrl/GPIO interlocking into the driver where it belongs, this patch drops the definition and usage of the mmc0_cd_pin_reference_design pinmux setting for the default mmc0 card detect GPIO pin.

* ARM: dts: sunxi: Remove no longer used pinctrl/sun4i-a10.h headerChen-Yu Tsai2017-03-271-1/+0
| | | | | | | | | | | | | | | | | All dts files for the sunxi platform have been switched to the generic pinconf bindings. As a result, the sunxi specific pinctrl macros are no longer used. Remove the #include entry with the following command: sed --follow-symlinks -i -e '/pinctrl\/sun4i-a10.h/D' \ arch/arm/boot/dts/sun?i*.* arch/arm/boot/dts/sun9i-a80.dtsi was then edited to remove the extra empty line.

| | | | | | | | | | | | The allwinner,pull property set to NO_PULL was really considered our default (and wasn't even changing the default value in the code). Remove these properties to make it obvious that we do not set anything in such a case.

Note the axp209 regulators are omitted as we don't have any use for them yet, and on some boards were not sure how exactly they are wired up.
