[PATCH 04/10] drm/tidss: Move reset to the end of dispc_init()

From: Tomi Valkeinen
Date: Wed Nov 01 2023 - 05:19:02 EST


We do a DSS reset in the middle of the dispc_init(). While that happens
to work now, we should really make sure that e..g the fclk, which is
acquired only later in the function, is enabled when doing a reset. This
will be handled in a later patch, but for now, let's move the
dispc_softreset() call to the end of dispc_init(), which is a sensible
place for it anyway.
