Hello Marek and Pali, > From: Pali Rohár <pali@kernel.org> > > Define DT node for UART clock "marvell,armada-3700-uart-clock" and use > this UART clock as a base clock for all UART devices. > > Signed-off-by: Pali Rohár <pali@kernel.org> > Reviewed-by: Marek Behún <kabel@kernel.org> > Signed-off-by: Marek Behún <kabel@kernel.org> Acked-by: Gregory CLEMENT <gregory.clement@bootlin.com> However for keeping bisectability we have to ensure that this patch will be applied after the drivers changes.
