Enable DRA7 processor MMU DT nodes

Hi Tony,

The following series enables the DSP and IPU MMUs on various TI DRA7xx/AM57xx boards. This is part 2 of the patches for enabling the MMUs on DRA7 SoCs (OMAP4 and OMAP5 are already supported on mainline).

Patches are baselined on your for-next branch with HEAD of a70cb93b6c2f ("Merge branch 'omap-for-v4.14/dt-v3' into for-next").

I have tested the patches on current TI DRA7xx/AM57xx boards (DRA7, DRA72, DRA71, DRA76 EVMs, AM571x & AM572x IDKs and AM57xx BeagleBoard-X15) as well as the OMAP4 Panda and OMAP5 uEVM. The boards can boot fine with just these patches, but requires the hwmod patches to be able to use them (otherwise get the failures from _od_fail_runtime_{resume/suspend} functions). There are no consumer devices for these yet, and they just probe but are not clocked/enabled by default, so the current System suspend is not affected.

regards
Suman

2.13.1

The MMU nodes for the remote processors IPU1, IPU2, DSP1 and DSP2 have all been enabled. All these nodes are relevant and valid for both the DRA7 EVM and DRA76 EVM boards, so are added in the dra7 common evm dtsi file.

Hi Tony,

Yeah, agreed. Original intention was that some of the other remoteproc related nodes can be customized per board, but there's nothing of that sort on iommu nodes. Will post a new series. Thanks for the review.

The MMU nodes for the remote processors IPU1, IPU2 and DSP1 have all been enabled. All these nodes are relevant and valid for both the DRA72x EVM variants and the DRA71 EVM, so are added in the common dts file. DSP2 MMU nodes are not present on DRA72x/DRA71x SoCs.
