From 36958598b7acf690b514141122234b1c3b8e4282 Mon Sep 17 00:00:00 2001 From: Mugunthan V N Date: Mon, 21 Sep 2015 20:23:51 +0530 Subject: ARM: dts: dra72-evm: remove cpsw gpio hogging and add mode-gpios With the current implementation of GPIO hogging and with gpio-pcf857x is built as module, ethernet doesn't work on boot and doesn't throw any error/warning to user. Ethernet becomes operational when inserting gpio-pcf857x module, even this time there is no error/warning logs to user that ethernet is operational. When using with NFS rootfs and gpio-pcf857x as module, board doesn't boot as it doesn't get any ip address and doesn't throw any error/warning. To over come this, now cpsw driver tries to get mode-gpios. When gpio-pcf857x is built as module it will throw error, so that user can decide either to built in gpio-pcf857x to continue with nfs boot or choose alternate rootfs filesystem like sd/ramdisk. 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.
