[PATCH] ARM: DTS: dra72-evm: remove cpsw gpio hogging and add select-slave-gpio

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since GPIO hogging fails to through error when booting with
gpio-pcf857x as module and NFS root filesystem. So by having
select-slave-gpio, it throw error to user so that the used can
make gpio-pcf857x as inbuilt for NFS. When using mmc/ramdisk as
root fs, cpsw will probe defer and re-probes again when
gpio-pcf857x module is inserted and ethernet becomes operational.
