Subject: [PATCH 1/2] mm: cma: export functions to get CMA base and size
Date: Wed, 29 May 2019 12:43:11 +0200
Make them usable in modules. Some drivers want to know where their
device CMA area is located to make better decisions about the DMA
programming.

From: Lucas Stach <l.stach@pengutronix.de>
Subject: [PATCH 2/2] drm/etnaviv: use CMA area to compute linear window offset
if possible
Date: Wed, 29 May 2019 12:43:12 +0200
The dma_required_mask might overestimate the memory size, or might not match
up with the CMA area placement for other reasons. Get the information about
CMA area placement directly from CMA where it is available, but keep the
dma_required_mask as an approximate fallback for architectures where CMA is
not available.
