Subject: [PATCH 042/122] dt-bindings: net: snps,dwmac: Add 'ahb'
|
||
|
|
reset/reset-name
|
||
|
|
|
||
|
|
According to:
|
||
|
|
stmmac_platform.c: stmmac_probe_config_dt
|
||
|
|
stmmac_main.c: stmmac_dvr_probe
|
||
|
|
|
||
|
|
dwmac controller may require one (stmmaceth) or two (stmmaceth+ahb)
|
||
|
|
reset signals, and the maxItems of resets/reset-names is going to be 2.
|
||
|
|
|
||
|
|
The gmac of Starfive Jh7110 SOC must have two resets.
|
||
|
|
it uses snps,dwmac-5.20 IP.
