Subject: [PATCH v3 0/4] soc/tegra: Prevent the PMC driver from corrupting interrupt routing

This is another respin of the initial version posted at [1] (the cover
letter describes the rational for doing this).

Jon, Thierry: I still haven't applied your TB tags as the series has
changed significantly again. Please let me know if they are still
valid.

If everybody is OK with this, I'll stick it in irq/irqchip-next.

* From v2 [2]:
  - Made the hierarchy trimming an internal functionnality, not
    requiring any intervention from driver code
  - Spelling fixes

* From v1 [1]:
  - Moved the hierarchy trimming part to its own patch, living in
    irqdomain.c
  - Reduced the PMC irqchip patch to the bare minimal in order to
    reduce the risk of merge conflicts

Marc Zyngier (4):
  genirq/irqdomain: Allow partial trimming of irq_data hierarchy
  gpio: tegra186: Allow optional irq parent callbacks
  soc/tegra: pmc: Allow optional irq parent callbacks
  soc/tegra: pmc: Don't create fake interrupt hierarchy levels
