Subject: [PATCH V5 0/8] i3c: master: svc: some bug fixes and add runtime pm support

Hi Miquel,

Currently, only the fourth patch needs to be reviewed, and the rest have been
added with your review tag.

Thank you very much for your comments! :)

V5 changes:
 - i3c: master: svc: add support for slave to stop returning data
   - remove <%s> in logs
   - add some spaces
   - !SVC_I3C_MSTATUS_STATE(reg) -> SVC_I3C_MSTATUS_STATE_IDLE(reg)
 - i3c: master: svc: add runtime pm support
   - create svc_i3c_master_prepare_clks() and svc_i3c_master_unprepare_clks()

V4 changes:
 - New patches:
   - i3c: master: svc: separate err, fifo and disable interrupt of reset function
   - i3c: master: svc: add the missing module device table
   - i3c: master: svc: enable the interrupt in the enable ibi function
 - i3c: master: svc: add support for slave to stop returning data
   - Only use COMPLETE flag in the read function.
   - Add a reset before each transfer.
 - i3c: master: svc: add runtime pm support
    - error path emit_stop only used in svc_i3c_master_do_daa() for one time, so
      remove it. Or it needs another goto command at the end of the function to
      skip it and to go to rpm_out.

V3 changes:
 - i3c: master: svc: add runtime pm support:
   - restore the error path of probe function
   - enable runtime pm just before i3c module reset

V2 changes:
 - align the parameters of the function in the second patch
 - add a new patch to support runtime PM.

Clark Wang (8):
  i3c: master: svc: move module reset behind clk enable
  i3c: master: svc: fix atomic issue
  i3c: master: svc: separate err, fifo and disable interrupt of reset
    function
  i3c: master: svc: add support for slave to stop returning data
  i3c: master: svc: set ODSTOP to let I2C device see the STOP signal
  i3c: master: svc: add runtime pm support
  i3c: master: svc: add the missing module device table
  i3c: master: svc: enable the interrupt in the enable ibi function
