Subject: [PATCH 09/10] arm64: dts: allwinner: a64: NanoPi-A64: Add Wifi/Bluetooth chip
Date: Fri,  6 Jul 2018 09:52:09 +0100	[thread overview]
Message-ID: <20180706085210.17952-10-andre.przywara@arm.com> (raw)
In-Reply-To: <20180706085210.17952-1-andre.przywara@arm.com>

The NanoPi-A64 has an on-board WiFi/Bluetooth combo chip, connected
to the usual MMC1 and UART1. The power is provided by the always-on
VCC_SYS_3.3V, but it uses pin L2 to enable the regulator.

Add the respective nodes to the DT to make it usable.
