Subject[PATCH 4.14 09/95] spi: pxa2xx: Allow 64-bit DMA
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

commit efc4a13724b852ddaa3358402a8dec024ffbcb17 upstream.

Currently the 32-bit device address only is supported for DMA. However,
starting from Intel Sunrisepoint PCH the DMA address of the device FIFO
can be 64-bit.

Change the respective variable to be compatible with DMA engine
expectations, i.e. to phys_addr_t.

Fixes: 34cadd9c1bcb ("spi: pxa2xx: Add support for Intel Sunrisepoint")
