Merge branch 'fixes' into next/soc
Merge in fixes here, since the last batch didn't make it in before the release of 4.20, and we might as well group them with this set of patches. * fixes: (822 commits) arm64: dts: renesas: draak: Fix CVBS input ARM: dts: Fix OMAP4430 SDP Ethernet startup ARM: dts: am335x-pdu001: Fix polarity of card detection input ARM: OMAP1: ams-delta: Fix audio permanently muted ARM: dts: omap5: Fix dual-role mode on Super-Speed port arm64: dts: rockchip: fix rk3399-rockpro64 regulator gpios ARM: dts: imx7d-nitrogen7: Fix the description of the Wifi clock ARM: imx: update the cpu power up timing setting on i.mx6sx Revert "arm64: dts: marvell: add CPU Idle power state support on Armada 7K/8K" ARM: dts: imx7d-pico: Describe the Wifi clock ARM: dts: realview: Fix some more duplicate regulator nodes MAINTAINERS: update entry for MMP platform ARM: mmp/mmp2: fix cpu_is_mmp2() on mmp2-dt MAINTAINERS: mediatek: Update SoC entry ARM: dts: bcm2837: Fix polarity of wifi reset GPIOs + Linux 4.20-rc5 Signed-off-by: Olof Johansson <olof@lixom.net>
