Current driver actually does not support simple ondemand governor as it's unable to provide device load information. So removing the unnecessary callback to avoid confusing. Right now the driver is using userspace governor by default. Signed-off-by: Dong Aisheng <aisheng.dong@nxp.com> --- drivers/devfreq/imx8m-ddrc.c | 13 ------------- 1 file changed, 13 deletions(-)
