Merge tag 'imx-fixes-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into fixes
The i.MX fixes for 4.9: - A couple of patches from Fabio to fix the GPC power domain regression which is caused by PM Domain core change 0159ec670763dd ("PM / Domains: Verify the PM domain is present when adding a provider"), and a related kernel crash seen with multi_v7_defconfig build. - Correct the PHY ID mask for AR8031 to match phy driver code. - Apply new added timer erratum A008585 for LS1043A and LS2080A SoC. - Correct vf610 global timer IRQ flag to avoid warning from gic driver after commit 992345a58e0c ("irqchip/gic: WARN if setting the interrupt type for a PPI fails"). * tag 'imx-fixes-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: ARM: imx: mach-imx6q: Fix the PHY ID mask for AR8031 ARM: dts: vf610: fix IRQ flag of global timer ARM: imx: gpc: Fix the imx_gpc_genpd_init() error path ARM: imx: gpc: Initialize all power domains arm64: dts: Add timer erratum property for LS2080A and LS1043A Signed-off-by: Olof Johansson <olof@lixom.net>
