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/1629113954-14084-1-git-send-email-deesin@codeaurora.org/
rproc qmp: https://patchwork.kernel.org/project/linux-arm-msm/cover/1629342136-3667-1-git-send-email-sibis@codeaurora.org/

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]

The SID configuration requirement for Modem on SC7280 is similar to the
ones found on SC7180/SDM845 SoCs. So, add the SC7280 modem compatible to
the list to defer the programming of the modem SIDs to the kernel.

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:

        memory@80000000 {
                device_type = "memory";
                /* We expect the bootloader to fill in the size */
                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?

Regards,
Bjorn

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.
