Subject: [PATCH] ARM: dts: rockchip: fix vref-supply for &saradc node rk3288 firefly reload
Date:   Sat, 14 Mar 2020 15:07:55 +0100
Message-Id: <20200314140755.4877-1-jbx6244@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

A test with the command below gives this error:

arch/arm/boot/dts/rk3288-firefly-reload.dt.yaml: saradc@ff100000:
'vref-supply' is a required property

PMIC Channel OUT11 with powername 'vcc_18'
(connected through R155 bridge with 'vccio_wl')
is used for the recovery key and ADC_AVDD_1V8.

Fix error by adding 'vcc_18' as vref for the saradc.
