On RZ/V2M, a specific procedure has to be followed to reset the watchdog IP. This series comes with two patches, one to fix the problem affecting RZ/Five, and one to fix the problem affecting RZ/V2M. Thanks, Fab Fabrizio Castro (1): watchdog: rzg2l_wdt: Handle TYPE-B reset for RZ/V2M Lad Prabhakar (1): watchdog: rzg2l_wdt: Issue a reset before we put the PM clocks drivers/watchdog/rzg2l_wdt.c | 45 +++++++++++++++++++++++++++++++----- 1 file changed, 39 insertions(+), 6 deletions(-)
