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/soc/imx/soc-imx8.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'drivers/soc') diff --git a/drivers/soc/imx/soc-imx8.c b/drivers/soc/imx/soc-imx8.c index fc6429f9170a..b1bd8e2543ac 100644 --- a/drivers/soc/imx/soc-imx8.c +++ b/drivers/soc/imx/soc-imx8.c @@ -103,6 +103,9 @@ static int __init imx8_soc_init(void) if (IS_ERR(soc_dev)) goto free_rev; + if (IS_ENABLED(CONFIG_ARM_IMX_CPUFREQ_DT)) + platform_device_register_simple("imx-cpufreq-dt", -1, NULL, 0); + return 0; free_rev: -- cgit v1.2.3-59-g8ed1b
