The GMU node now requires a specific dma-range property so that the driver
can use the DMA API to do the few memory allocations required by the GMU.
This sets the IOMMU iova allocator to match the 'uncached' part of the
GMU virtual address space.
v2: Fix the dma-ranges tag. The third pair should b
The GMU has very few memory allocations and uses a flat memory space so
there is no good reason to go out of our way to bypass the DMA APIs which
were basically designed for this exact scenario.
v2: Pass force_dma false to of_dma_configure to require that the DMA
region be set up and return error
When CONFIG_INIT_ON_ALLOC_DEFAULT_ON the GMU memory allocator runs afoul of
cache coherency issues because it is mapped as write-combine without clearing
the cache after it was zeroed.
Rather than duplicate the hacky workaround we use in the GEM allocator for the
same reason it turns out that we

In v4 I added my tags [1]. Please keep them for future patches unless
something maj
Patch [1] adds a "mem_iface_clock" in the clocks list for smmu device.
This patch updates the yaml doc file for smmu by adding the definition
for this new clock.
1: https://patchwork.freedesktop.org/patch/352718/
Sharat Masetty (1):
dt-bindings: arm-smmu: update clocks and bindings for sc7180 S
This patch adds a clock definition needed for powering on the GPU TBUs
and the GPU TCU.
