Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM DT updates from Olof Johansson: "Device tree contents continue to be the largest branches we submit. This time around, some of the contents worth pointing out is: New SoC platforms: - Freescale i.MX 7Solo - Broadcom BCM23550 - Cirrus Logic EP7209 and EP7211 (clps711x platforms)_ - Hisilicon HI3519 - Renesas R8A7792 Some of the other delta that is sticking out, line-count wise: - Exynos moves of IP blocks under an SoC bus, which causes a large delta due to indentation changes - a new Tegra K1 board: Apalis - a bunch of small updates to many Allwinner platforms; new hardware support, some cleanup, etc" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (426 commits) ARM: dts: sun8i: Add dts file for inet86dz board ARM: dts: sun8i: Add dts file for Polaroid MID2407PXE03 tablet ARM: dts: sun8i: Use sun8i-reference-design-tablet for ga10h dts ARM: dts: sun8i: Use sun8i-reference-design-tablet for polaroid mid2809pxe04 ARM: dts: sun8i: reference-design-tablet: Add drivevbus-supply ARM: dts: Copy sun8i-q8-common.dtsi sun8i-reference-design-tablet.dtsi ARM: dts: sun5i: Use sun5i-reference-design-tablet.dtsi for utoo p66 dts ARM: dts: sun5i: Use sun5i-reference-design-tablet.dtsi for dit4350 dts ARM: dts: sun5i: reference-design-tablet: Remove mention of q8 ARM: dts: sun5i: reference-design-tablet: Set lradc vref to avcc ARM: dts: sun5i: Rename sun5i-q8-common.dtsi sun5i-reference-design-tablet.dtsi ARM: dts: sun5i: Move q8 display bits to sun5i-a13-q8-tablet.dts ARM: dts: sunxi: Rename sunxi-q8-common.dtsi sunxi-reference-design-tablet.dtsi ARM: dts: at91: Don't build unnecessary dtbs ARM: dts: at91: sama5d3x: separate motherboard gmac and emac definitions ARM: dts: at91: at91sam9g25ek: fix isi endpoint node ARM: dts: at91: move isi definition to at91sam9g25ek ARM: dts: at91: fix i2c-gpio node name ARM: dts: at91: vinco: fix regulator name ARM: dts: at91: ariag25 : fix onewire node ...
