v11:
  - Fix typo in systimer (Thanks Angelo)

v10:
  - Fix systimer properties (Thanks Amjad)
  - Drop components of the patchset that have already been merged

v9:
  - Fix a regression in v8 that broke the USB port
  - Remove superfluous include in mt8365.dtsi
  - Fix some naming issues pointed out by dtbs_check

v8:
  - Add binding descriptions for mediatek,mt8365-systimer and
    mediatek,mt8365-uart
  - Specify ranges with parameters for u3phy

Tested-by: Kevin Hilman <khilman@baylibre.com>

v7:
  - Update GIC information in mt8365.dtsi (thanks to Marc Zyngier for
    pointing out the problem)
  - Adjust the timer to match the updated GIC information

v6:
  - Add systimer in mt8365.dtsi
  - Add I/D caches and L2 cache details in mt8365.dtsi
  - Move bl31_secmon_reserved from mt8365.dtsi to mt8365-evk.dts
  - Fix inconsistent indentation in mt8365-pinctrl example
  - Further mt8365.dtsi cleanups
  - Submit to additional maintainers spotted by get_maintainer.pl

v5:
  - Reorder top-level entries in mediatek,mt8365-pinctrl.yaml to match
    example-schema
  - Use consistent quotes

v4:
  - Remove pins-are-numbered references that have been holding things up
    now that the patches removing it from dt-bindings have landed in linux-next

v3:
  - Remove a number of components that are not yet supported (they will
    come back alongside the corresponding drivers)
  - Address issues found by dt_binding_check (mostly fixing pinctrl
    bindings)
  - Address issues pointed out in comments
  - Reorder patches

v2:
  - Add missing dt-bindings documentation
  - Small cleanups addressing issues in v1 pointed out by Krzysztof Kozlowski


Bernhard Rosenkränzer (2):
  dt-bindings: irq: mtk, sysirq: add support for mt8365
  dt-bindings: serial: mediatek,uart: add MT8365

Fabien Parent (1):
  arm64: dts: mediatek: Initial mt8365-evk support

Tested (again) and things are working well.  This is the last patch
remaining to be merged.  As soon as this lands in linux-next, I'll add
this board to my KernelCI lab.

Hello,

A bit of a late reply, but I've just noticed an issue related to this
patch.

These two nodes cause the infracfg clocks to be registered twice, with
the second probe of the clk-mt8365 driver failing with -EEXIST.

These are the messages printed by v6.6-rc6:

[    0.540254] Failed to register clk ifr_pmic_tmr: -EEXIST
[    0.541003] clk-mt8365: probe of 1020e000.infracfg failed with error -17
