How about using mtk_scp_of_data to denote if the clock should be acquired?

The SCP clock design is changed on mt8195 that doesn't need to control SCP clock on kernel side. Signed-off-by: Tinghan Shen <tinghan.shen@mediatek.com> --- drivers/remoteproc/mtk_scp.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
