Merge tag 'devicetree-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
- Convert FPGA bridge, all TPMs (finally), and Rockchip HDMI bindings
to schemas
- Improvements in Samsung GPU schemas
- A few more cases of dropping unneeded quotes in schemas
- Merge QCom idle-states txt binding into common idle-states schema
- Add X1E80100, SM8650, SM8650, and SDX75 SoCs to QCom Power Domain
Controller
- Add NXP i.mx8dl to SCU PD
- Add synaptics r63353 panel controller
- Clarify the wording around the use of 'wakeup-source' property
- Add a DTS coding style doc
- Add smi vendor prefix
- Fix DT_SCHEMA_FILES incorrect matching of paths outside the kernel
tree
- Disable sysfb (e.g. EFI FB) when simple-framebuffer node is present
- Fix double free in of_parse_phandle_with_args_map()
- A couple of kerneldoc fixes
