Merge tag 'renesas-fixes2-for-v5.0' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into arm/fixes
Second Round of Renesas ARM Based SoC Fixes for v5.0
Enable DMA for SCIF2 on R-Car M3-W (r8a7796) and M3-n (r8a77965), and
(RZ/G2M) r8a774a1 SoCs.
This is was omitted from patches enabling DMA for other SCIF devices on the
same SoCs due to missing documentation. However, it is regarded as a fix
as arguably those patches claim to add this feature.
Per-SoC patches are provided to ease backporting of this fix as the kernel
version to be fixed is different for each SoC.
