Merge tag 'imx-drivers-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into soc/drivers
i.MX drivers update for 6.6: - A series from NXP i.MX developers (Peng Fan, etc.) to update imx-scu and imx-scu-irq firmware drivers. - Add dedicated lockdep class for nested genpd locks to fix a lockdep warning in imx93-blk-ctrl driver. - A change from Rob to explicitly include correct DT headers for i.MX SoC drivers. - Use devm_platform_ioremap_resource() in imx-weim bus driver. * tag 'imx-drivers-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: firmware: imx: scu-irq: support identifying SCU wakeup source from sysfs firmware: imx: scu-irq: enlarge the IMX_SC_IRQ_NUM_GROUP firmware: imx: scu-irq: add imx_scu_irq_get_status firmware: imx: scu-irq: fix RCU complaint after M4 partition reset firmware: imx: scu: use EOPNOTSUPP firmware: imx: scu: use soc name for soc_id firmware: imx: scu: increase RPC timeout firmware: imx: scu: change init level to subsys_initcall_sync soc: imx: Explicitly include correct DT includes bus: imx-weim: use devm_platform_ioremap_resource soc: imx: imx93-blk-ctrl: Add dedicated lockdep class for nested genpd locks Link: https://lore.kernel.org/r/20230813133354.847010-1-shawnguo@kernel.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>
