Subject: spi/pxa2xx-pci: Add support for Intel Braswell
X-Git-Tag: v4.14-rc1~6620^2~28
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=39d36536d4e89461c0733a48d5ffc9b730751983;p=platform%2Fkernel%2Flinux-rpi.git

spi/pxa2xx-pci: Add support for Intel Braswell

Instead of one port we have 3 ports and all of them can take advantage of
the shared DMA controller.
