Subject: spi: pxa2xx: Allow 64-bit DMA
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a436539bc16fdc6cb69cfa069ca0388df8d53d4b;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

spi: pxa2xx: Allow 64-bit DMA

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.
