Subject: [PATCH 03/10] spi: dw: Add support for client driver memory operations
Date: Wed, 13 May 2020 16:00:24 +0200	[thread overview]
Message-ID: <20200513140031.25633-4-lars.povlsen@microchip.com> (raw)
In-Reply-To: <20200513140031.25633-1-lars.povlsen@microchip.com>

This minor change allow dw-spi drivers to register
spi_controller_mem_ops memory operations if the platform supports it.
