Subject: [PATCH V2 3/3] arm64: dts: rockchip: Add saradc node to Indiedroid Nova
Date: Mon, 18 Sep 2023 12:32:55 -0500	[thread overview]
Message-ID: <20230918173255.1325-4-macroalpha82@gmail.com> (raw)
In-Reply-To: <20230918173255.1325-1-macroalpha82@gmail.com>

From: Chris Morgan <macromorgan@hotmail.com>

Add ADC support for the Indiedroid Nova, as well as the two ADC buttons
found on the device. The buttons are documented as "boot" and
"recovery". The boot button is used by the bootloader to boot into USB
recovery mode. The recovery button use is currently unknown.
