Mali-DP650 supports warming up the SMMU translations, by sending requsts to the SMMU before a buffer is read. There are two modes supported: - PARTIAL: could be enabled when the buffer is composed of 4K or 64K pages, the display hardware will send a configurable number of requests before the actual reading. - FULL: could be enabled when the buffer is composed of 1M or 2M pages, the display hardware will send requests before reading for all pages composing the buffer. This patch adds a mechanism for detecting the page size and set the MMU prefetch mode if possible. Changes since v1: - For imported buffers use the already populated drm_gem_cma_object.sgt instead of calling driver.gem_prime_get_sg_table, which works just for buffers allocated through the gem_cma API.
