Cover letter [PATCH 00/03] ARM: shmobile: Lager SYS-DMAC and MMCIF prototype
ARM: shmobile: Lager SYS-DMAC and MMCIF prototype
[PATCH 01/03] ARM: shmobile: r8a7790: SYS-DMAC prototype [PATCH 02/03] ARM: shmobile: r8a7790: SYS-DMAC and MMCIF prototype [PATCH 03/03] ARM: shmobile: Lager DT reference MMCIF DMAC prototype
These patches add DMAC prototype support for the MMCIF on Lager. Written to show how to make use of platform devices for DMA support until the DT bindings for the DMA hardware have been stabilized.
Not for upstream merge. More-than-32-bit physical addresses are not handled by this code - LPAE is not supported.
