From: Doug Anderson Date: Wed, 3 Sep 2014 20:44:27 +0000 (-0700) Subject: spi/rockchip: Mark DMA as optional X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6e3be9bbeaa841eb65fa7570e0c542b2c1483fca;p=linux.git spi/rockchip: Mark DMA as optional The Rockchip SPI controller works fine without DMA (aside from a few warnings). The DMA property even implies this, saying: DMA request names should include "tx" and "rx" if present. Officially mark the properties as optional.
