[U-Boot] [PATCH v2 2/7] sunxi: video: Split out TCON code
Jernej Skrabec

Mon Mar 20 22:01:23 UTC 2017
TCON unit has similar layout and functionality also on newer SoCs. This
commit splits out TCON code for easier reuse later.

Changes in v2:
- lcdc conversion to use struct display_timing is done in a new patch
- fix issue with lcdc_enable() calls
