Subject: [PATCH v2 13/14] ARM: dts: sun8i: r40: Add RTC device node
Date: Mon, 3 Dec 2018 22:58:24 +0800 [thread overview]
Message-ID: <20181203145825.20511-14-wens@csie.org> (raw)
In-Reply-To: <20181203145825.20511-1-wens@csie.org>
The R40 has an RTC hardware block, which has additional registers
that are not related to RTC or clock functions, and is otherwise
compatible with the H3's RTC.
Add a device node for it, and fix up any references to the LOSC.
Acked-by: Maxime Ripard <maxime.ripard@bootlin.com>
Tested-by: Corentin Labbe <clabbe.montjoie@gmail.com>
