Since GPIO hogging fails to through error when booting with gpio-pcf857x as module and NFS root filesystem. So by having mode-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. Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> --- The driver patch is applied to net-next branch (also present in linux-next) with commit '1d147ccbfc35 ("drivers: net: cpsw: Add support to drive gpios for ethernet to be functional") and logs [1] also pushed a branch [2] for testing.
