Subject: [PATCH v6 07/11] mfd: intel-m10-bmc: Prefix register defines with M10BMC_N3000
Date:   Mon, 16 Jan 2023 12:08:41 +0200
Message-Id: <20230116100845.6153-8-ilpo.jarvinen@linux.intel.com>
In-Reply-To: <20230116100845.6153-1-ilpo.jarvinen@linux.intel.com>

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Precedence: bulk

Prefix the M10BMC defines register defines with M10BMC_N3000 to make it
more obvious these are related to some board type. All current
non-N3000 board types have the same layout so they'll be reused. The
less generic makes it more obvious they're not meant for the
generic/interface agnostic code.
