2022-06-15ARM: dts: sunxi: Drop resets from r_pio nodesSamuel Holland
None of the sunxi pin controllers have a module reset line. This is confirmed by documentation (A80) as well as experimentation (A33). Let's remove the inaccurate properties.

2019-08-23ARM: dts: sunxi: Add mdio bus sub-node to GMACChen-Yu Tsai
The DWMAC binding never supported having the Ethernet PHY node as a direct child to the controller, nor did it support the "phy" property as a way to specify which Ethernet PHY to use. What seemed to work was simply the implementation ignoring the "phy" property and instead probing all addresses on the MDIO bus and using the first available one. The recent switch from "phy" to "phy-handle" breaks the assumptions of the implementation, and does not match what the binding requires. The binding requires that if an MDIO bus is described, it shall be a sub-node with the "snps,dwmac-mdio" compatible string. Add a device node for the MDIO bus, and move the Ethernet PHY node under it. Also fix up the #address-cells and #size-cells properties where needed.

2017-02-07ARM: DTS: Fix register map for virt-capable GICMarc Zyngier
Since everybody copied my own mistake from the DT binding example, let's address all the offenders in one swift go. Most of them got the CPU interface size wrong (4kB, while it should be 8kB), except for both keystone platforms which got the control interface wrong (4kB instead of 8kB). In a few cases where I knew for sure what implementation was used, I've added the "arm,gic-400" compatible string. I'm 99% sure that this is what everyone is using, but short of having the TRM for all the other SoCs, I've left them alone.

In the past, all the MMC pins had allwinner,pull = <SUN4I_PINCTRL_NO_PULL>; which was actually a no-op. We were relying on U-boot to set the bias pull up for us. These properties were removed as part of the fix up to actually support no bias on the pins. During the transition some boards experienced regular MMC time-outs during normal operation, while others completely failed to initialize the SD card. Given that MMC starts in open-drain mode and the pull-ups are required, it's best to enable it for all the pin settings.

2016-08-27ARM: dts: sun9i: Add missing #interrupt-cells to R_PIO pinctrl device nodeChen-Yu Tsai
The R_PIO device node is missing #interrupt-cells, which causes interrupt parsing to fail to match it as a valid interrupt controller. Add #interrupt-cells to it. Also remove the unnecesary #address-cells and #size-cells.

2016-08-22ARM: dts: sun9i: Switch to the AC100 RTC clock outputs for osc32kChen-Yu Tsai
The 32.768 kHz clock inside the A80 SoC is fed from an external source, typically the AC100 RTC module. Make the osc32k placeholder a fixed-factor clock so board dts files can specify its source.

2016-01-25ARM: dts: sun9i: Include SDC2_RST pin in mmc2_8bit_pinsChen-Yu Tsai
mmc2_8bit_pins is used with eMMC chips, which also have a reset pin. The MMC controller also has a reset output that is supported. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2016-01-25ARM: dts: sun9i: Use sun9i specific mmc compatibleChen-Yu Tsai
sun9i/A80 MMC controllers have a larger FIFO, and the FIFO DMA trigger levels can be increased. Also, the mmc module clock parent has a higher clock rate, and the sample and output delay phases are different.

2015-12-03ARM: dts: sun9i: Add NMI controller device nodeChen-Yu Tsai
The Allwinner A80 SoC has an NMI controller. NMI is an external interrupt pin exclusely used with PMICs and other system critical peripherals (such as RTC) in Allwinner's reference designs.

2015-12-01ARM: dts: sun9i: Add Reduced Serial Bus controller device node to A80 dtsiChen-Yu Tsai
This patch adds a device node for the Reduced Serial Bus (RSB) controller and the defacto pinmux setting to the A80 dtsi. Since there is only one possible pinmux setting for RSB, just set it in the dtsi. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
