Merge tag 'imx-fixes-5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into fixes
i.MX fixes for 5.2: - A build fix for soc-imx8 driver which needs SOC_BUS support. To avoid dealing with the dependency for every single i.MX SoC bus driver, we selects at from architecture level. - A fix on i.MX SCU firmware driver to ensure SCU irq is enabled only after IPC is ready. - A regression fix on cpuidle-imx6sx driver, which causes some characters loss on serial communication. * tag 'imx-fixes-5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: ARM: imx: cpuidle-imx6sx: Restrict the SW2ISO increase to i.MX6SX firmware: imx: SCU irq should ONLY be enabled after SCU IPC is ready arm64: imx: Fix build error without CONFIG_SOC_BUS Signed-off-by: Olof Johansson <olof@lixom.net>
