Subject: [PATCH 0/4] ARM: exynos: Fix Odroid U3 USB/LAN when TFTP booting (power sequence)

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").


Best regards,
Krzysztof
