From 58ffe7a02583bd19bb83c8bc7e277705625316a2 Mon Sep 17 00:00:00 2001 From: Rongjun Ying Date: Thu, 30 Jan 2014 13:54:24 +0800 Subject: pinctrl: sirf: add pin group for USP0 for atlas6 USP0 has multiple functions, and has RX and TX frame sync signals, for some scenarios like audio PCM, we don't need both of them. so here we add two possibilities for USP0 only holding one of TX and RX frame sync. commit 8385af02bad only added this group for prima2, and missed atlas6. This patch fixes it.
