Previous attempt to fix HSYNC and VSYNC polarity settings for dw_hdmi on sunxi
wasn't completely correct - there's another bug in dw_hdmi driver.
This series fixes hsync/vsync settings in sunxi glue driver and
applies proper fix to dw_hdmi

v2: don't revert earlier fix, just use correct bits for hsync and vsync

Vasily Khoruzhick (2):
  sunxi: video: HDMI: use correct bits for HSYNC and VSYNC polarity.

HSYNC is bit 8, and VSYNC is bit 9.

Currently dw_hdmi configures HSYNC polarity using VSYNC setting from
EDID and vice versa. Fix it, since it breaks displays where HSYNC
and VSYNC polarity differs
