    Subject[PATCH AUTOSEL 4.19 05/52] 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.
