From 86cf6788a661b8cb459f259e373c5daf09221abe Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai <wens@csie.org> Date: Tue, 25 Apr 2017 23:25:04 +0800 Subject: drm/sun4i: Set TCON clock inside sun4i_tconX_mode_set Currently we are configuring the TCON's dot clock or special clock directly from the encoder mode_set functions. Since we already provide mode_set helper functions for the TCON's 2 channels, we can set the respective clock from those helpers, and reduce the exposure of the TCON's internals.
