Provide a mtk_mmsys_ddp_connect() and mtk_mmsys_disconnect() functions to
replace mtk_ddp_add_comp_to_path() and mtk_ddp_remove_comp_from_path().
Those functions will allow DRM driver and others to control the data
path routing.

The mmsys system controller is not only a pure clock controller, so
update the binding documentation to reflect that apart from providing
clocks, it also provides routing and miscellaneous control registers.

This patchset adds support for the LCD panel of PinePhone.
The first 3 patches are for the panel itself, and the last 2 patches are
for enabling it on PinePhone.
PATCH 4 is the fix of a bug in sun6i_mipi_dsi which will gets triggered
on XBD599.

Many of the direct returns of error skipped doing the pte_unmap(). All non
zero exit paths must unmap the pte.
The pte_unmap() is split unnaturally like this because some of the error
exit paths trigger a sleep and must release the lock before sleeping.

I guess you should have been told in your company how to use get_maintainer.p
Add helper functions that can allow i915 to detect and control
an integrated privacy screen via ACPI methods. These shall be used
in the next patch.

This eventually calls into handle_mm_fault() which is a sleeping function.
Release the lock first.
hmm_vma_walk_hole() does not touch the contents of the PUD, so it does not
need the lock.

Well, I wouldn't bet that any specific number is enough. When gtk
starts rendering using vulkan by default the number of contexts of a
standard gnome desktop will be pretty high I guess
