My first suspect is the commit below so adding Miaoqing. commit b2d70d4944c1789bc64376ad97a811f37e230c87 Author: Miaoqing Pan <miaoqing@codeaurora.org> Date: Mon Mar 7 10:38:15 2016 +0800 ath9k: make GPIO API to support both of WMAC and SOC commit 61b559dea40e ("ath9k: add extra GPIO led support") added ath9k to support access SOC's GPIOs, but implemented in a separated API: ath9k_hw_request_gpio(). So this patch make the APIs more common, to support both of WMAC and SOC GPIOs. The new APIs as below, void ath9k_hw_gpio_request_in(); void ath9k_hw_gpio_request_out(); void ath9k_hw_gpio_free(); NOTE, the BSP of the SOC chips(AR9340, AR9531, AR9550, AR9561) should set the corresponding MUX registers correctly.
