From: Juuso Oikarinen Date: Thu, 7 Oct 2010 07:16:42 +0000 (+0300) Subject: wl1271: Support FEM autodetection X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4b34d432b0fcff422304de4eb49d6da861fe335c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git wl1271: Support FEM autodetection In the NVS/INI-parameters for the driver/firmware there is the FEM (front end module) selection option, which may configure the hardware FEM via autodetection or manual selection. So far, there has been support for manual selection only. Add support for FEM autodetection. Signed-off-by: Juuso Oikarinen Signed-off-by: John W.
