From: Yan-Hsuan Chuang Date: Thu, 13 Apr 2017 18:06:56 +0000 (-0500) Subject: rtlwifi: btcoex: 21a 2ant: finer adjustment of bt power X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=aed6b11e4fc2134ccd4db4d1a41b2cc8fed980f3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git rtlwifi: btcoex: 21a 2ant: finer adjustment of bt power Originally we only increase/decrease bt power in a fixed power gap, this patch makes us be able to modify bt power for multiple power gaps and we can precisely adjust the bt power.
