VOP can support BGR formats in all windows thanks to red/blue swap option
provided in WINx_CTRL0 registers. This patch enables support for
ABGR8888, XBGR8888, BGR888 and BGR565 formats by using this feature.

Hi Mark,

Thanks for review.

Right, good catch.

Hmm, according to the datasheet of RK3288 I have (0.7, October 2014),
there is a field called hwc_rb_swap at bit 12 of HWC_CTRL0 register.
Is it an error in the datasheet?

Best regards,
Tomasz
