Subject: [PATCH] spi: axi-spi-engine: use common AXI macros
Date: Fri,  2 Feb 2024 15:31:32 -0600	[thread overview]
Message-ID: <20240202213132.3863124-2-dlechner@baylibre.com> (raw)

This avoid duplicating the same macros in multiple drivers by reusing
the common AXI macros for the version register.
