This patch series add coredump support for modem on SDM845, MSM8996
and MSM8916 SoCs. Modem requires the mba to be loaded before a
coredump can be performed and this is achieved using a custom per
segment dump function.

V5:
Add software bypass to avoid high MX current in mpss_load error path.
Remove the proxy votes of clk/regs only after the active/reset clks/regs.
Reclaim MBA memory after mpss_load failure in mba_reclaim func.
Revert to dump_fn to as done with v3 with a mask based approach.

V4:
Addressed Bjorn's comments.

V3:
[bjorn]:replace prepare/unprepare ops with a more generalised per segment
dump function

V2:
Introduce prepare/unprepare ops for rproc coredump

Sibi Sankar (5):
remoteproc: Introduce custom dump function for each remoteproc segment
remoteproc: Add mechanism for custom dump function assignment
remoteproc: qcom: q6v5-mss: Refactor mba load/unload sequence
remoteproc: qcom: q6v5-mss: Add custom dump function for modem
remoteproc: qcom: q6v5-mss: Register segments/dumpfn for coredump
