Subject: [PATCH v2 1/1] ARM: dts: aspeed-g6: add aliases for mdio nodes
Date: Tue, 25 Oct 2022 13:50:46 +0800 [thread overview]
Message-ID: <20221025055046.1704920-1-potin.lai.pt@gmail.com> (raw)
Add aliases for mdio nodes so that we can use name to lookup the
bus address of Aspeed SOC.
For example:
root@bletchley:~# cat /sys/firmware/devicetree/base/aliases/mdio0
/ahb/mdio@1e650000
root@bletchley:~# cat /sys/firmware/devicetree/base/aliases/mdio1
/ahb/mdio@1e650008
root@bletchley:~# cat /sys/firmware/devicetree/base/aliases/mdio2
/ahb/mdio@1e650010
root@bletchley:~# cat /sys/firmware/devicetree/base/aliases/mdio3
/ahb/mdio@1e650018
