Subject[PATCH 4.19 23/79] bus: ti-sysc: Fix using configured sysc mask value
Date
From: Tony Lindgren <tony@atomide.com>

[ Upstream commit e212abd452a4af3174fcd469d46656f83e135a19 ]

We have cases where there are no softreset bits like with am335x lcdc.
In that case ti,sysc-mask = <0> needs to be handled properly.
