Commit Message

Nikita Shubin June 1, 2023, 5:45 a.m. UTC
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.

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@80010000/ethernet@80010000
    - s/use_dma/ep9301,use-dma
    - added i2s to bk3
