[PATCH v7 0/4] firmware: ti_sci: Introduce BOARDCFG_MANAGED mode for Jacinto family

[Thomas Richard (TI)]

This is the 7th iteration of this series. I did some changes as suggested
by Nishanth. In ti_sci driver I added a lock around set_irq() and
free_irq() to keep hash list consistent in case of concurrent accesses, and
now ti_sci driver tries to restore all IRQs even in case of error.
On the clock side, get_parent() errors are now handled. If we fail to get
parent_id for a clock, set_parent() is not called anymore in
restore_context().
Other minor changes are listed in the changelog.

Best Regards,
Thomas

Changes in v7:
- ti_sci: add a lock around set_irq() and free_irq() to keep hash list
  consistent.
- ti_sci: in free_irq() add warning in case we are in a path that shall not
  be run.
- ti_sci: free an IRQ if we failed to add it in the hash list.
- ti_sci: during resume in case of error, try to restore remaining IRQs and
  logs all errors, then return the latest one.
- sci-clk: add Stephen's AB tag and Brian's RB tag.
- sci-clk: handle get_parent() error, in restore_context() do not call
  set_parent() with parent_id=0 if get_parent() failed.
