Re: [PATCH 0/3] dts: arm64: sunxi: add initial support for t95 tv box

[Kamil Kasperski]

Hi Jernej, Andre!

Thanks for the reply. My board has a name "H616-T95MAX-AXP313A-v3.0".

I believe these boards are two different revisions and the one with 
AXP313A is a newer one, besides incorrectly label as v3.0. Sharing 
common configuration between boxes is also a good idea but for this 
specific configuration I would be cautious. From my experience with this 
board the default configuration for X96 Mate is not working at all. I 
suspect because of the PMIC and DRAM differences.

Memory installed in X96 Mate is DDR3L and in mine T95 it's DDR3, hynix 
H5TQ2G43BFR, that requires 1.5V to operate.

The rest of configuration for both boards, like HDMI, MMC, EPHY and 
audio codec seems to be the same across almost all H616-based boxes that 
I've researched.


Moreover please let me update the patches and send v2 that aligns with 
mainline branch. I've incorrectly assumed to use sunxi fork instead of 
master. Sorry!
