Also, this driver actually supports all MediaTek SoCs, the Kconfig menu entry and file name itself should be updated with more generic name to drop "MT8173" Signed-off-by: Sean Wang --- drivers/cpufreq/Kconfig.arm | 8 ++++---- drivers/cpufreq/Makefile | 2 +- drivers/cpufreq/{mt8173-cpufreq.c => mtk-cpufreq.c} | 2 ++ 3 files changed, 7 insertions(+), 5 deletions(-) rename drivers/cpufreq/{mt8173-cpufreq.c => mtk-cpufreq.c} (99%) diff --git a/drivers/cpufreq/Kconfig.arm b/drivers/cpufreq/Kconfig.arm index 74ed7e9..79aece7 100644 --- a/drivers/cpufreq/Kconfig.arm +++ b/drivers/cpufreq/Kconfig.arm @@ -87,14 +87,14 @@ config ARM_KIRKWOOD_CPUFREQ This adds the CPUFreq driver for Marvell Kirkwood SoCs. -config ARM_MT8173_CPUFREQ - tristate "Mediatek MT8173 CPUFreq support" +config ARM_MEDIATEK_CPUFREQ + tristate "CPU Frequency scaling support for MediaTek SoCs" depends on ARCH_MEDIATEK && REGULATOR - depends on ARM64 || (ARM_CPU_TOPOLOGY && COMPILE_TEST) + depends on ARM || ARM64 || COMPILE_TEST depends on !CPU_THERMAL || THERMAL select PM_OPP help - This adds the CPUFreq driver support for Mediatek MT8173 SoC. + This adds the CPUFreq driver support for MediaTek SoCs. config ARM_OMAP2PLUS_CPUFREQ bool "TI OMAP2+" diff --git a/drivers/cpufreq/Makefile b/drivers/cpufreq/Makefile index b7e78f0..4956f5d 100644 --- a/drivers/cpufreq/Makefile +++ b/drivers/cpufreq/Makefile @@ -58,7 +58,7 @@ obj-$(CONFIG_ARM_EXYNOS5440_CPUFREQ) += exynos5440-cpufreq.o obj-$(CONFIG_ARM_HIGHBANK_CPUFREQ) += highbank-cpufreq.o obj-$(CONFIG_ARM_IMX6Q_CPUFREQ) += imx6q-cpufreq.o obj-$(CONFIG_ARM_KIRKWOOD_CPUFREQ) += kirkwood-cpufreq.o -obj-$(CONFIG_ARM_MT8173_CPUFREQ) += mt8173-cpufreq.o +obj-$(CONFIG_ARM_MEDIATEK_CPUFREQ) += mtk-cpufreq.o obj-$(CONFIG_ARM_OMAP2PLUS_CPUFREQ) += omap-cpufreq.o obj-$(CONFIG_ARM_PXA2xx_CPUFREQ) += pxa2xx-cpufreq.o obj-$(CONFIG_PXA3xx) += pxa3xx-cpufreq.o diff --git a/drivers/cpufreq/mt8173-cpufreq.c b/drivers/cpufreq/mtk-cpufreq.c similarity index 99% rename from drivers/cpufreq/mt8173-cpufreq.c rename to drivers/cpufreq/mtk-cpufreq.c index fd1886f..481ec77 100644 --- a/drivers/cpufreq/mt8173-cpufreq.c +++ b/drivers/cpufreq/mtk-cpufreq.c @@ -575,6 +575,8 @@ static struct platform_driver mt8173_cpufreq_platdrv = { /* List of machines supported by this driver */ static const struct of_device_id mt8173_cpufreq_machines[] __initconst = { + { .compatible = "mediatek,mt2701", }, + { .compatible = "mediatek,mt7623", }, { .compatible = "mediatek,mt817x", }, { .compatible = "mediatek,mt8173", }, { .compatible = "mediatek,mt8176", }, -- 2.7.4
