From 65f31b5e7029e55d4f7020a1d0b0658a50ea73cb Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Wed, 18 May 2011 20:25:05 +0200 Subject: [PATCH] rt2x00: Enable PA_PE bits in TX_PIN_CFG according to active band. (split off from the earlier RT35xx patch submitted by Shiang) There's no point in enabling the PA_PE bits for the bands that we are not active on.
