Subject: [PATCH v5 0/5] Add coredump support for Q6v5 Modem remoteproc

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
