Subject: [PATCH] spi: pxa2xx: Allow 64-bit DMA
Git-commit: efc4a13724b852ddaa3358402a8dec024ffbcb17
No-fix: 7956fadd40af82cec610a0ccf1ca937e0dfecf94
Patch-mainline: v4.17-rc6
References: bsc#1051510
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.
