[PATCH 06/11] [media] marvell-ccic: drop ctlr_reset()

From: Lubomir Rintel <lkundrak@v3.sk>
Date: 2018-11-05 07:31:39
Also in: linux-media, lkml
Subsystem: media input infrastructure (v4l/dvb), the rest · Maintainers: Mauro Carvalho Chehab, Linus Torvalds

This accesses the clock registers directly and thus is not too
devicetree friendly. If it's actually needed it needs to be done
differently.
