[PATCH v4 0/5] Support alpha blending in MTK display driver

[Jason-JH Lin (林睿祥)]

Hi Alper,

I think that's a platform issue because it works find in my MT8188
platform, but I don't have any MT8173 platform.

Can you help me test the fix patch in your MT8173 platform?
I'll provide a fix patch in 2 weeks via Google Chat.

Regards,
Jason-JH.Lin
