Subject: [PATCH 5.10.y-cip 06/14] dt-bindings: rtc: isil,isl1208: Document clock and clock-names properties
Date: Fri, 18 Aug 2023 10:27:59 +0100	[thread overview]
Message-ID: <20230818092807.159112-7-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20230818092807.159112-1-biju.das.jz@bp.renesas.com>

commit 138f352556d791d7e0ca3ac9a4f4815123af8c82 upstream.

As per the HW manual, XTOSCB bit setting is as follows

If using an external clock signal, set the XTOSCB bit as 1 to
disable the crystal oscillator.

If using an external crystal, the XTOSCB bit needs to be set at 0
to enable the crystal oscillator.

Document clock and clock-names properties.
