Subject: [PATCH 08/11] MIPS: mobileye: eyeq5: add OLB syscon node
Date: Wed, 10 Apr 2024 19:12:37 +0200	[thread overview]
Message-ID: <20240410-mbly-olb-v1-8-335e496d7be3@bootlin.com> (raw)
In-Reply-To: <20240410-mbly-olb-v1-0-335e496d7be3@bootlin.com>

The OLB ("Other Logic Block") is a syscon region hosting clock, reset
and pin controllers. It contains registers such as I2C speed mode that
need to be accessible by other nodes.
