ptp: clockmatrix: deprecate firmware older than 4.8.7
Add deprecated flag to indicate < v4.8.7. Fix idtcm_enable_tod() call correct settime(). Signed-off-by: Min Li <min.li.xe@renesas.com> Link: https://lore.kernel.org/r/1607442117-13661-4-git-send-email-min.li.xe@renesas.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
