From 4d28ba1d62c48d5242ca30fa0051ab3498bc5c5b Mon Sep 17 00:00:00 2001 From: Leonard Crestez Date: Mon, 13 May 2019 11:01:38 +0000 Subject: cpufreq: Add imx-cpufreq-dt driver Right now in upstream imx8m cpufreq support just lists a common subset of OPPs because the higher ones should only be attempted after checking speed grading in fuses. Add a small driver which checks speed grading from nvmem cells before registering cpufreq-dt. This driver allows unlocking all frequencies for imx8mm and imx8mq and could be applied to other chips like imx7d Signed-off-by: Leonard Crestez Signed-off-by: Viresh Kumar --- drivers/cpufreq/cpufreq-dt-platdev.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'drivers/cpufreq/cpufreq-dt-platdev.c') diff --git a/drivers/cpufreq/cpufreq-dt-platdev.c b/drivers/cpufreq/cpufreq-dt-platdev.c index 47729a22c159..19c1aad57e26 100644 --- a/drivers/cpufreq/cpufreq-dt-platdev.c +++ b/drivers/cpufreq/cpufreq-dt-platdev.c @@ -108,6 +108,9 @@ static const struct of_device_id blacklist[] __initconst = { { .compatible = "calxeda,highbank", }, { .compatible = "calxeda,ecx-2000", }, + { .compatible = "fsl,imx8mq", }, + { .compatible = "fsl,imx8mm", }, + { .compatible = "marvell,armadaxp", }, { .compatible = "mediatek,mt2701", }, -- cgit v1.2.3
