Subject: [PATCH v2 03/11] dt-bindings: rtc: Convert Allwinner A10 RTC to a schema
Date: Tue, 28 May 2019 22:30:33 +0200	[thread overview]
Message-ID: <c9598ec7e668303e62c5e533f98096ca22d847aa.1559075389.git-series.maxime.ripard@bootlin.com> (raw)
In-Reply-To: <434446bc5541d7dfe5823874355c7db8c7e213fa.1559075389.git-series.maxime.ripard@bootlin.com>

The older Allwinner SoCs have an embedded RTC supported in Linux, with a
matching Device Tree binding.

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.

-Required properties:
-- compatible : Should be "allwinner,sun4i-a10-rtc" or "allwinner,sun7i-a20-rtc"
-- reg: physical base address of the controller and length of memory mapped
-  region.
-- interrupts: IRQ line for the RTC.
