Hi,

Thanks to Markus Reichl, I got an Odroid U3 to work with. Thanks to Peter
Chen, we got a power sequence generic library which solves my long
standing Odroid U3 problem - no LAN9730 if it was enabled by bootloader.

My previous attempts for this can be found here [0].

This patchset is based on Peter's v11 of power sequence [1].
Patchset is available also on my Github [2].

More detailed analysis is described in patch 2/4 ("ARM: dts: exynos: Fix
LAN9730 on Odroid U3 after tftpboot").
It's rather late, but I finally had a chance to test this and it works.

So:

Tested-by: Hans Verkuil <redacted>

This was with u-boot version v2016.09.01 and kernel 4.11.0-rc1.

Regards,

	Hans

Best regards,
Krzysztof
