Subject: [edk2-devel] [RFC 1/6] Silicon/Bcm283x: Document the I2C registers
Date: Wed, 10 Jan 2024 18:04:21 -0600 [thread overview]
Message-ID: <20240111000426.2735007-2-jeremy.linton@arm.com> (raw)
In-Reply-To: <20240111000426.2735007-1-jeremy.linton@arm.com>
Since we are now using I2C in edk2, its helpful if we document
the register names.
