From: Roland Stigge Date: Thu, 6 Sep 2012 09:39:29 +0000 (+0200) Subject: ARM: LPC32xx: Remove board specific GPIO init X-Git-Tag: firefly_0821_release~3680^2~1964^2^2~3 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7a5deff68f9e0a1db170ac9dd3b2b4aaddc1b80c;p=firefly-linux-kernel-4.4.55.git ARM: LPC32xx: Remove board specific GPIO init This patch removes a board specific GPIO initialization (for MMC power) from the platform initialization. On the reference boards (PHY3250 and EA3250), this separate initialization is not necessary, now reducing board specific initialization in the platform init of phy3250.c.
