From 24942e8af19e5090374776a57db97b350ffd0fa6 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 22 Oct 2012 13:29:19 -0700 Subject: ARM: OMAP2+: Fix location of select PINCTRL Commit 8f31cefe (ARM: OMAP2+: select PINCTRL in Kconfig) added select PINCTRL, but accdentally added it to a wrong location. We want to select if for ARCH_OMAP2PLUS, not for ARCH_OMAP2PLUS_TYPICAL.

As Russell has pointed out, that commit isn't fixing Software Flow Control at all, and it actually makes it even more broken. It was agreed to revert this commit and use Russell's latest UART patches instead.
