* ARM: dts: sunxi: Switch MMC nodes away from cd-inverted propertyTuomas Tynkkynen2018-02-131-2/+1
| | | | | | | | | | Using the cd-inverted property is not useful when GPIOs are used as card detects since the polarity can be specified with the usual GPIO_ACTIVE_(HIGH|LOW) GPIO flags. It has also caused confusion for U-Boot developers, so migrate all sunxi boards away from cd-inverted.

* ARM: dts: sun4i: Provide default muxing for relevant controllersMaxime Ripard2017-10-131-6/+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 Ripard2017-10-131-4/+4
| | | | | | | | | | | | 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: Change LRADC node names to avoid warningsMaxime Ripard2017-10-091-3/+3
| | | | | | | | | | | | | | One of the usage of the LRADC is to implement buttons. The bindings define that we should have one subnode per button, with their associated voltage as a property. However, there was no reg property but we still used the voltage associated to the button as the unit-address, which eventually generated warnings in DTC. Rename the node names to avoid those warnings. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
* ARM: dts: sun4i: Remove all useless pinctrl nodesMaxime Ripard2017-10-061-9/+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: sunxi: Remove useless allwinner,pull propertyMaxime Ripard2016-12-261-1/+0
| | | | | | | | | | | | 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.

* ARM: sunxi: DT: Add stdout-path propertyMaxime Ripard2015-04-271-0/+8
| | | | | | | | | | | | Add UART aliases and stdout-path property for all the Allwinner boards so that we won't have to rely on the bootargs' console= value, while working with legacy bootloaders. While we're at it, also remove the mentions of earlyprintk in the bootargs, that will remove our default bootargs entirely, and allow the kernel to boot on a system even if DEBUG_LL is configured for another system.
