2018-11-28ARM: dts: sun5i: Remove underscores from nodes namesMaxime Ripard11-21/+20
Some GPIO pinctrl nodes cannot be easily removed, because they would also change the pin configuration, for example to add a pull resistor or change the current delivered by the pin. Those nodes still have underscores and unit-addresses in their node names in our DTs, so adjust their name to remove the warnings. Use that occasion to also fix some poorly chosen node-names.

2018-11-28ARM: dts: r9a06g032: Correct the GIC DT node namePhil Edworthy1-1/+1
Harmless mistake, but it's incorrect. The DT spec provides recommendations for the node names: "The name of a node should be somewhat generic, reflecting the function of the device and not its precise programming model. If appropriate, the name should be one of the following choices: ... interrupt-controller" Signed-off-by: Phil Edworthy <phil.edworthy@renesas.com> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

2018-11-28ARM: dts: r8a77470: Add SDHI1 supportFabrizio Castro1-0/+11
Althought interface SDHI1 found on the RZ/G1C SoC (a.k.a. r8a77470) is compatible with the R-Car Gen3 ones, its OF compatibility is restricted to the SoC specific compatible string to avoid confusion, as from a more generic perspective the RZ/G1C is sharing the most similarities with the R-Car Gen2 family of SoCs, and there is a combination of R-Car Gen2 compatible SDHI IPs and R-Car Gen3 compatible SDHI IP on this specific chip. This patch adds the SoC specific part of SDHI1 support, and since SDHI1 comes with internal DMA, its DT node looks fairly different from SDHI0 and SDHI2.

2018-11-28ARM: dts: r8a77470: Add SDHI0 supportFabrizio Castro1-1/+16
RZ/G1C comes with two different types of IP for the SDHI interfaces, SDHI0 and SDHI2 share the same IP type, and such an IP is also compatible with the one found in R-Car Gen2. SDHI1 IP on the other hand is compatible with R-Car Gen3 with internal DMA. This patch completes the SDHI support of the R-Car Gen2 compatible IPs, including fixing the max-frequency definition of SDHI2, as it turns out there is a bug in Section 1.3.9 of the RZ/G1C Hardware User's Manual (Rev. 1.00 Oct. 2017).

2018-11-28ARM: dts: sun5i: Change pinctrl nodes to avoid warningMaxime Ripard19-119/+127
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: sun5i: Change LRADC node names to avoid warningsMaxime Ripard6-22/+22
One of the usage of the LRADC is to implement buttons. The bindings define that we should have one subnode per button, with their associated voltage as a property. However, there was no reg property but we still used the voltage associated to the button as the unit-address, which eventually generated warnings in DTC.
