ARM: shmobile: Lager SYS-DMAC and SDHI prototype
Magnus Damm
maintainerPATCH v2 5/7 ARM: shmobile: Lager SYS-DMAC and SDHI prototype
From: Magnus Damm <[email protected]>
Hook up SYS-DMAC prototype support for SDHI on Lager.
Local platform device version of SYS-DMAC and local slave IDs are used together with AUXDATA. CD and WP pins, regulators and clocks are provided via DT.
Only the DT reference case is covered. Not for upstream merge.
