Subject: [PATCH v2 02/11] spi: pxa2xx: Reorganize the SSP type retrieval
Date: Thu, 30 May 2024 18:09:58 +0300	[thread overview]
Message-ID: <20240530151117.1130792-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20240530151117.1130792-1-andriy.shevchenko@linux.intel.com>

The old Intel platforms, such as Intel Braswell, also provide
the property of SSP type. Reorganize the pxa2xx_spi_init_pdata()
to take that into account.
