Subject: [RESEND v6 2/3] ARM: dts: am43xx: Describe the magnetic reader/ADC1 hardware module
Date: Fri, 26 Nov 2021 15:24:12 +0100	[thread overview]
Message-ID: <20211126142413.354770-3-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20211126142413.354770-1-miquel.raynal@bootlin.com>

This hardware module is close to the am33xx ADC module but instead of
featuring a touchscreen it has a magnetic reader capability.
