2019-01-18ARM: dts: sun4i-a10: Add Video Engine and reserved memory nodesPaul Kocialkowski
This adds nodes for the Video Engine and the associated reserved memory for the A10. Up to 96 MiB of memory are dedicated to the CMA pool. The VPU can only map the first 256 MiB of DRAM, so the reserved memory pool has to be located in that area. Following Allwinner's decision in downstream software, the last 96 MiB of the first 256 MiB of RAM are reserved for this purpose.

2019-01-18ARM: dts: sun4i: Add support for the C1 SRAM region with the SRAM controllerPaul Kocialkowski
This adds support for the C1 SRAM region (to be used with the SRAM controller driver) for the A10 platform. The region is shared between the Video Engine and the CPU. Signed-off-by: Paul Kocialkowski <paul.kocialkowski@bootlin.com> Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>

2018-07-11ARM: dts: sun4i: Switch to new system control compatible stringPaul Kocialkowski
This switches the sun4i-a10 dtsi to use the new compatible for the system-control block (previously named SRAM controller) instead of the deprecated one. The node name is also updated to reflect the fact that the controller described is really about system control rather than SRAM control.

2017-10-13ARM: dts: sun4i: Provide default muxing for relevant controllersMaxime Ripard
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 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.

2017-01-10ARM: dts: sunxi: Explicitly enable pull-ups for MMC pinsChen-Yu Tsai
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.

2015-07-28ARM: sunxi: dt: Convert users to the PIO interrupts bindingMaxime Ripard
The current DTs were setting the cell size to 2, but used the default xlate function that was assuming an interrupt cell size of 1, leading to the second part of the cell (the flags) being ignored, while we were having an inconsistent binding between the interrupts and gpio (that could also be used as interrupts). That "binding" doesn't work either with newer SoCs that have multiple irq banks. Now that we fixed the pinctrl driver to handle this like it should always have been handled, convert the DT users, and while we're at it, remove the size-cells property of PIO that is completely useless.
