From ab3943fe57a23526ed5a89b3260b5a57d7746e63 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Thu, 20 Oct 2016 13:42:56 +0200 Subject: [PATCH] ARM64: dts: meson-gxbb: Add P20x Wifi SDIO support Add Wifi module support on the Amlogic P20x boards on the SDIO port. The Wifi module also needs a 32768Hz clock provided by the PWM E port through a pwm-clock node in it's power sequence.
