This patch series adds support for booting the Modem Q6 DSP found on
Qualcomm's SC7280 SoCs.
Depends on:
qmp_send: https://patchwork.kernel.org/project/linux-arm-msm/cover/[email protected]/
rproc qmp: https://patchwork.kernel.org/project/linux-arm-msm/cover/[email protected]/
V3:
* Keep the memory map version in commit message (patch 6). [Bjorn]
* Rename tcsr node and add qualifying compatibles to tcsr and imem nodes
(patch 8). [Bjorn]
* Place remoteproc_mpss node in alphabetical order above pinctrl
section (patch 10). [Stephen]
V2:
* Misc. typos (patch 3). [Matthias]
* Document the q-channel takedown procedure (patch 5). [Matthias]
* Split reserved memory updates between SoC and platform (patch 6). [Matthias]

Add out of reset sequence support for modem sub-system on SC7280 SoCs.
It requires access to an additional set of qaccept registers, external
power/clk control registers and halt vq6 register to put the modem back
into reset.

This should conflict with the memory defined in this file:

device_type = "memory";

reg = <0 0x80000000 0 0>;

I think this should be updated?

Vinod,
I prefer we leave ^^ node untouched.
For platforms using hyp_mem, the
regions defined in the memory map
are valid and for the other platforms
not using hyp_mem we would just delete
them in the board files anyway.

Logically this node describes where there is RAM, the reserved-memory
then subtracts blocks of memory out of that. So I think it's perfectly
legal for a region at the base to be marked as no-map.
That said, isn't the address in the memory node just a placeholder?

Nitpick:
memory-region = <&mba_mem>, <&mpss_mem>;
would be better as it indicates that &mpss_mem isn't being parsed when
&mba_mem is being parsed, i.e. they're independent phandles.
