This series first converts the debugfs files in the pinctrl subsystem to
octal permissions and then adds a new debugfs file "pinmux-select".
Group name and function name can be written to "pinmux-select" which
will cause the pin function for the specified group to be activated on
the pin controlle
Switch over pinctrl debugfs files to use octal permissions as they are
preferred over symbolic permissions. Refer to commit f90774e1fd27
("checkpatch: look for symbolic permissions and suggest octal instead").
Note: S_IFREG flag is added to the mode by __debugfs_create_file()
in fs/debugfs/inode.c
This is useful when checking conditions during checkpoint=disable in Android.

This patch series was created to help catching a rather long standing
problem with smp_call_function_any() and friends.
Very rarely a remote cpu seems not to execute a queued function and
the cpu queueing that function request will wait forever for the
CSD lock to be released by the remote cpu.

In order to help identifying problems with IPI handling and remote
function execution add some more data to IPI debugging code.
There have been multiple reports of cpus looping long times (many
seconds) in smp_call_function_many() waiting for another cpu executing
a function like tlb flushing. Mos

Hi,
This is the v8 series to introduce i.MX8qm/qxp Display Processing Unit(DPU)
DRM support.
DPU is comprised of a blit engine for 2D graphics, a display controller
and a command sequencer. Outside of DPU, optional prefetch engines can
fetch data from memory prior to some DPU fetchunits of blit
Artificially use 'plane' and 'old_plane_state' to avoid 'not used' warning.
The precedent has already been set by other macros in the same file.
