X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=65f31b5e7029e55d4f7020a1d0b0658a50ea73cb;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git 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.
