Merge tag 'imx-fixes-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into arm/fixes
i.MX fixes for 5.14: - A couple of fixes on MMDC driver to add missing iounmap() and clk_disable_unprepare(), and a follow-up fix. - Fix missing-prototypes warning in SRC driver. - Revert commit 7d981405d0fd ("soc: imx8m: change to use platform driver"), which breaks i.MX8M system that has CAAM driver enabled. - One fix on imx53-m53menlo pinctrl configuration. - Increase the PHY reset duration for imx6qdl-sr-som to fix intermittent issues where the PHY would be unresponsive every once in a while. - Add missing flag for in-band signalling between PHY and MAC on kontron-sl28-var2 board to fix network support. - Limit the SDIO Clock on Colibri iMX6ULL to 25MHz for fixing wireless noise issue. - Fix sysclk node name for LS1028A so that U-Boot is able to update the "clock-frequency" property. * tag 'imx-fixes-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: ARM: dts: imx: Swap M53Menlo pinctrl_power_button/pinctrl_power_out pins ARM: imx: fix missing 3rd argument in macro imx_mmdc_perf_init ARM: dts: colibri-imx6ull: limit SDIO clock to 25MHz arm64: dts: ls1028: sl28: fix networking for variant 2 Revert "soc: imx8m: change to use platform driver" ARM: dts: imx6qdl-sr-som: Increase the PHY reset duration to 10ms ARM: imx: common: Move prototype outside the SMP block ARM: imx: add missing clk_disable_unprepare() ARM: imx: add missing iounmap() arm64: dts: ls1028a: fix node name for the sysclk Link: https://lore.kernel.org/r/20210726023221.GF5901@dragon Signed-off-by: Arnd Bergmann <arnd@arndb.de>
