From: Kobi L Date: Mon, 29 Dec 2014 06:24:06 +0000 (+0200) Subject: wlcore: enable sleep during AP mode operation X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e2f1e50f62ae70c7ddde8420ed586c6a1aa1e28c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git wlcore: enable sleep during AP mode operation Enable ELP authorization in AP mode and enable the use of the wakeup bit in the ELP register. Introduce AP role sleep configuration which is disabled by default. When configured, it allows the AP to sleep when ELP is authorized for it.
