From: Liviu Dudau (ARM) Date: Mon, 23 Nov 2015 15:52:41 +0000 (+0100) Subject: drm/i2c: tda998x: increase the supported dotclock frequency to 165MHz for TDA19988 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e4618c467d9ea600cc1412b32ad520f22b8b4833;p=linux-beck.git drm/i2c: tda998x: increase the supported dotclock frequency to 165MHz for TDA19988 Spec sheet states that the TDA19988 supports up to 165MHz dotclock speeds. Without this change modes higher than 1080p are un-attainable.
