[PATCH 06/10] drm/tidss: Check for K2G in in dispc_softreset()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



K2G doesn't have softreset feature. Instead of having every caller of
dispc_softreset() check for K2G, move the check into dispc_softreset(),
and make dispc_softreset() return 0 in case of K2G.
