Subject: [PATCH v8 07/10] MIPS: mobileye: eyeq5: add OLB syscon node
Date: Tue, 27 Feb 2024 15:55:28 +0100	[thread overview]
Message-ID: <20240227-mbly-clk-v8-7-c57fbda7664a@bootlin.com> (raw)
In-Reply-To: <20240227-mbly-clk-v8-0-c57fbda7664a@bootlin.com>

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