Add initial support for dynamic frequency switching on pieces of the imx interconnect fabric. All this driver actually does is set a clk rate based on an opp table. +config ARM_IMX_DEVFREQ + tristate "i.MX DEVFREQ Driver" + depends on ARCH_MXC || COMPILE_TEST + select DEVFREQ_GOV_PASSIVE + select DEVFREQ_GOV_SIMPLE_ONDEMAND + select DEVFREQ_GOV_USERSPACE + select PM_OPPDoes it support ALL ARCH_MXC SoCs?
Only imx8m currently but out of tree we support bus+dram frequency switching for ~10 imx6/7 SOCs, all other than imx7ulp. When imx8 was upstreamed as the first 64-bit imx chip the arm64 maintainers told us to drop stuff like ARCH_FSL_IMX8MM so there is no per-soc kconfig more specific than "ARCH_MXC". I guess we could make it depend on (ARCH_MXC && ARM64) but the ARM64 would eventually be dropped anyway. -- Regards, Leonard _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
