Subject: [PATCH v2 02/14] spi: pxa2xx: Utilize MMIO and physical base from struct ssp_device
Date: Fri, 23 Apr 2021 21:24:29 +0300	[thread overview]
Message-ID: <20210423182441.50272-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20210423182441.50272-1-andriy.shevchenko@linux.intel.com>

We have a duplication of MMIO and physical base addresses in
the struct driver_data, get rid of it and reuse members from
struct ssp_device instead.
