2019-07-22ARM: dts: sunxi: Switch from phy to phy-handleMaxime Ripard1-1/+1
The phy device tree property has been deprecated in favor of phy-handle, let's replace it. Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>
2018-02-13ARM: dts: sunxi: Switch MMC nodes away from cd-inverted propertyTuomas Tynkkynen1-2/+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.

2017-10-13ARM: dts: sun4i: Provide default muxing for relevant controllersMaxime Ripard1-4/+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>
2017-10-13ARM: dts: sun4i: Change pinctrl nodes to avoid warningMaxime Ripard1-4/+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.

2017-10-06ARM: dts: sun4i: Remove all useless pinctrl nodesMaxime Ripard1-16/+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>
2017-05-14ARM: sunxi: Drop mmc0_cd_pin_reference_design pinmux settingChen-Yu Tsai1-1/+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.

2017-03-27ARM: dts: sunxi: Remove no longer used pinctrl/sun4i-a10.h headerChen-Yu Tsai1-1/+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.

2016-12-26ARM: sunxi: Remove useless allwinner,pull propertyMaxime Ripard1-2/+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.

2016-07-04ARM: dts: sunxi: Add a startup delay for fixed regulator enabled physHans de Goede1-0/+1
It seems that recent kernels have a shorter timeout when scanning for ethernet phys causing us to hit a timeout on boards where the phy's regulator gets enabled just before scanning, which leads to non working ethernet. A 10ms startup delay seems to be enough to fix it, this commit adds a 20ms startup delay just to be safe. This has been tested on a sun4i-a10-a1000 and sun5i-a10s-wobo-i5 board, both of which have non-working ethernet on recent kernels without this fix.

2015-06-01ARM: dts: sun4i: Add A10 SRAM and SRAM controllerMaxime Ripard1-0/+4
The A10 has a few SRAM that can be mapped either to a device or to the CPU, with the mapping being controlled by a SRAM controller. Add the SRAM controller, the SRAM that it drives and the section that can be used by the various devices.

2015-05-10ARM: sunxi: dt: Remove the FSF addressMaxime Ripard1-5/+0
The FSF address triggers a warning on checkpatch, saying that the FSF license is already present in the Linux source code, and that it has already changed in the past. Remove it from our DT, as suggested. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2015-05-02ARM: sunxi: dts: split IR pins for A10 and A20Marcus Cooper1-1/+1
Currently none of the target boards nor the driver supports IR TX. However this pin is used in a few instances as a GPIO. Split the pin ctrl descriptions so that only the IR RX is configured to be used. Signed-off-by: Marcus Cooper <codekipper@gmail.com> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2015-04-27ARM: sunxi: DT: Add stdout-path propertyMaxime Ripard1-0/+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.

2015-01-21ARM: sunxi: DT: Convert the DTs to use a header for the pinctrl nodesMaxime Ripard1-4/+5

2014-10-21ARM: sun4i: hackberry: Relicense the device tree under GPLv2/X11Maxime Ripard1-5/+41
The current GPL only licensing on the DTSI makes it very impractical for other software components licensed under another license.

At a node for the axp209, and where necessary the i2c controller to the dts for various boards. 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. Adding support for just the axp209 without the regulators is still useful, as it will give us power-button and poweroff support.

Add nodes for the usb-phy and ehci- and ohci-usb-host controllers. Based on fex file settings, the fex file also contains a mysterious line: usb_hub_vcc_en_gpio = port:PB09<1><0><default><0> Which also clashes with usbc0, which has: usb_drv_vbus_gpio = port:PB09<1><0><default><0> So if usb does not work properly we need someone with a hackberry to look closer into this.

2013-04-08ARM: sunxi: dt: Reorganize the dtsiMaxime Ripard1-1/+1
In the early days, the A10 and A13 shared quite some code. Nowadays it shares less and less code, the A31 diverging even more, so it doesn't make much sense to continue to maintain this structure, just use one DTSI for every SoC, and that's it.
