Subject: [PATCH 5.4 072/215] drm/sun4i: tcon: Separate quirks for tcon0 and tcon1 on A20

From: Andrey Lebedev <andrey@...edev.lt>

[ Upstream commit cd0ecabdc953397ed0378022b3b90e0c0871c2eb ]

Timing controllers on A20 are not equivalent: tcon0 on A20 supports
LVDS output and tcon1 does not. Separate the capabilities by
introducing independent set of quirks for each of the tcons.
