Subject: [PATCH 07/12] mfd: intel-m10-bmc: Downscope SPI related defines
Date:   Tue,  8 Nov 2022 16:43:00 +0200
Message-Id: <20221108144305.45424-8-ilpo.jarvinen@linux.intel.com>
In-Reply-To: <20221108144305.45424-1-ilpo.jarvinen@linux.intel.com>
References: <20221108144305.45424-1-ilpo.jarvinen@linux.intel.com>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Precedence: bulk

Move SPI related defines to per interface from the global header. This
makes it harder to shoot oneself into foot.

Some bitfield defs are also moved to intel-m10-bmc-core which seems
more appropriate for them.
