2018-11-28ARM: dts: sun6i: Provide default muxing for relevant controllersMaxime Ripard
The I2C and MMC 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. Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com> Acked-by: Chen-Yu Tsai <wens@csie.org>
2018-11-28ARM: dts: sun6i: Change pinctrl nodes to avoid warningMaxime Ripard
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.

2018-11-28ARM: dts: sun6i: Remove redundant MMC pinmux tuningMaxime Ripard
Some boards override the MMC pin muxing settings in order to enable the pull-ups and change the drive strength to a value higher than the default. While this was needed in the earlier days, this is now the default setting for those pins, and therefore we don't need those board-specific settings anymore.

2018-11-28ARM: dts: sun6i: Remove card detect pull-upMaxime Ripard
Boards usually have an external pull-up on the card-detect signal, so there's no need to add another one. This also removes a DTC warning. Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com> Acked-by: Chen-Yu Tsai <wens@csie.org>
2018-02-13ARM: dts: sunxi: Switch MMC nodes away from cd-inverted propertyTuomas Tynkkynen
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.

2017-03-27ARM: dts: sunxi: Remove no longer used pinctrl/sun4i-a10.h headerChen-Yu Tsai
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.

Now that we can handle the generic pinctrl bindings, convert our DT to it. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Acked-by: Chen-Yu Tsai <wens@csie.org> Reviewed-by: Linus Walleij <linus.walleij@linaro.org>

2016-06-03ARM: dts: sun6i: yones-toptech-bs1078-v2: Drop constraints on dc1sw regulatorChen-Yu Tsai
This is the same issue fixed in commit dcf5341f0150 ("ARM: dts: sun8i-q8-common: Do not set constraints on dc1sw regulator"). Commit message copied: dc1sw is an on/off only regulator and as such it cannot have constraints. This is a limitation of the kernel regulator implementation which resolves supplies on the first regulator_get(), which is done after applying constraints, and applying the constrains will fail because it calls _regulator_get_voltage() and _regulator_do_set_voltage() both of which will fail on a switch regulator when there is no supply (yet). This causes registering of all axp22x regulators to fail with the following errors: [ 1.395249] vcc-lcd: failed to get the current voltage(-22) [ 1.405131] axp20x-regulator axp20x-regulator: Failed to register dc1sw [ 1.412436] axp20x-regulator: probe of axp20x-regulator failed with error -22 This commit removes the constrains on dc1sw / vcc-lcd fixing this problem. Note that dcdc1 itself is contrained to the exact same values, so this does not change anything.

2015-11-17dts: sun6i: yones toptech bs1078 v2: Add AXP221 support to dtsLawrence Yu
Enable the axp221 PMIC chip in the dts file. Allows board to power off correctly from the poweroff command This board requires dc1sw to be enabled in order to provide a power source for the 5V DCDC converter that powers USB2. This board uses dldo1 for 3.3V wifi power This board requires dldo3 to be enabled at 2.8V in order to provide voltage to the pullup resistors for the i2c0 bus.
