Subject: [PATCH v3 2/9] ARM: dts: r9a06g032: Add dependency to sysctrl in the PCI bridge
Date: Wed, 7 Dec 2022 17:24:28 +0100 [thread overview]
Message-ID: <20221207162435.1001782-3-herve.codina@bootlin.com> (raw)
In-Reply-To: <20221207162435.1001782-1-herve.codina@bootlin.com>
In r9a06g032 (RZ/N1 SoC family), the USB hosts are impacted by
the h2mode setting. This setting will be done at sysctrl level
and must not be done while USB hosts are running.
Express this dependency using 'depends-on' property.
