Subject: [PATCH v1 35/43] ARM: dts: add device tree for ep93xx Soc
This adds a divice for Cirrus ep93xx SoC amd ts7250 board that has been
my testing target for ep93xx device support.
Also inluded device tree for Liebherr BK3.1 board through it's not a
complete support.
Signed-off-by: Nikita Shubin <nikita.shubin@...uefel.me>

Notes:
v0 -> v1:
- add empty chosen node
- s/dallas,rtc-m48t86/st,m48t86/
- changed phy_id to phy-handle
- dropped gpio chip-label's
- s/eth@...10000/ethernet@...10000
- s/use_dma/ep9301,use-dma
- added i2s to bk3
