2020-05-04ARM: dts: uniphier: add #address-cells and #size-cells to SPI nodesMasahiro Yamada
Documentation/devicetree/bindings/spi/spi-uniphier.txt requires #address-cells and #size-cells, but they are missing in actual DT files. Also, 'make ARCH=arm dtbs_check' is really noisy. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2020-05-04ARM: dts: uniphier: Add XDMAC nodeKunihiko Hayashi
Add external DMA controller support implemented in UniPhier SoCs. This supports for Pro4, Pro5 and PXs2. Signed-off-by: Kunihiko Hayashi <hayashi.kunihiko@socionext.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2020-03-17ARM: dts: uniphier: Set SCSSI clock and reset IDs for each channelKunihiko Hayashi
Currently common clock and reset IDs were used, however, each clock and reset ID should be used for each channel. Pro5 and PXs2 are affected by this fix, but the SCSSI clock gate of Pro5 is common to all channels.

2020-01-18ARM: dts: uniphier: add reset-names to NAND controller nodeMasahiro Yamada
The Denali NAND controller IP has separate reset control for the controller core and registers. Add the reset-names, and one more phandle accordingly. This is the approved DT-binding. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2019-06-26ARM: dts: uniphier: update to new Denali NAND bindingMasahiro Yamada
With commit d8e8fd0ebf8b ("mtd: rawnand: denali: decouple controller and NAND chips"), the Denali NAND controller driver migrated to the new controller/chip representation. Update DT for it. In the new binding, the number of connected chips are described in DT instead of run-time probed. I added just one chip to the reference boards, where we do not know if the on-board NAND device is a single chip or multiple chips. If we added too many chips into DT, it would end up with the timeout error in nand_scan_ident(). I changed all the pinctrl properties to use the single CS.

2018-11-27ARM: dts: uniphier: Add all CPUs in cooling mapsViresh Kumar
Each CPU can (and does) participate in cooling down the system but the DT only captures a handful of them, normally CPU0, in the cooling maps. Things work by chance currently as under normal circumstances its the first CPU of each cluster which is used by the operating systems to probe the cooling devices. But as soon as this CPU ordering changes and any other CPU is used to bring up the cooling device, we will start seeing failures. Also the DT is rather incomplete when we list only one CPU in the cooling maps, as the hardware doesn't have any such limitations. Update cooling maps to include all devices affected by individual trip points. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2018-08-28ARM: uniphier: dts: add more clocks to Denali NAND controller nodeMasahiro Yamada
Catch up with the new binding of the Denali IP where three clocks, "nand", "nand_x", "ecc" are required. For UniPhier SoCs, the "nand_x" and "ecc" are tied up because they are both 200MHz. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2018-07-19ARM: dts: uniphier: Add missing cooling device properties for CPUsViresh Kumar
The cooling device properties, like "#cooling-cells" and "dynamic-power-coefficient", should either be present for all the CPUs of a cluster or none. If these are present only for a subset of CPUs of a cluster then things will start falling apart as soon as the CPUs are brought online in a different order. For example, this will happen because the operating system looks for such properties in the CPU node it is trying to bring up, so that it can register a cooling device. Add such missing properties.

I notice some mistakes in the SoC DTSI; wrong interrupts properties of timer nodes, mismatch between the node name and the compatible for sdctrl block.
