tinydrm/mipi-dbi: Use dma-safe buffers for all SPI transfers

2019-03-20T11:02:41Z

Buffers passed to spi_sync() must be dma-safe even for tiny buffers since some SPI controllers use DMA for all transfers.

drm/tinydrm: Use struct drm_rect

2019-01-17T09:57:03Z

This prepares for the switch to drm_atomic_helper_dirtyfb() in the next patch. The damage helper returns a drm_rect so switch to that everywhere including using a pointer in the dirty functions. This is a non-functional change except for the debug print which looks a bit different.
