To have a working display through DPI, a workaround has been
implemented downstream to add "mm_dpi0_dpi0" and "dpi0_sel" to
the DPI node. Shortly, that add an extra clock.
It seems consistent to have the "dpi0_sel" as parent.
Additionnaly, "vpll_dpix" isn't used/managed.
Then, set the "mm_dpi0_dpi0" parent clock to "dpi0_sel".
The new clock tree is:
clk26m
lvdspll
lvdspll_X (2, 4, 8, 16)

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:
The existing code can be both improved and simplified. To make this
change easier to manage, first add new implementation and then remove
deadcode in a separate patch.
Simplification achieved with:
- reduce the amount of resources requested by the driver i.e.: IPC and
CLDMA request_irq() merged into one
- reduce the number of DSP ops from 2 to 1:
irq_handler/thread() vs dsp_interrupt()
- drop ambiguity around CLDMA interrupt, let skl.c handle that
explicitly as it is the only user
With that done, switch to the new implementation and remove unused
members. While the change is non-trivial, from functional perspective
status quo is achieved.

After commit 2c7d399e55 ("smb: client: reuse file lease key in
compound operations") the client started reusing lease keys for
rename, unlink and set path size operations to prevent it from
breaking its own leases and thus causing unnecessary lease breaks to
same connection.
The implementation relies on positive dentries and
cifsInodeInfo::lease_granted to decide whether reusing lease keys for
the compound requests. cifsInodeInfo::lease_granted was introduced by
commit 0ab95c2510 ("Defer close only when lease is enabled.") to
indicate whether lease caching is granted for a specific file, but
that can only happen until file is open, so
cifsInodeInfo::lease_granted was left uninitialised in ->alloc_inode
and then client started sending random lease keys for files that
hadn't any leases.
This fixes the following test case against samba:
mount.cifs //srv/share /mnt/1 -o ...,nosharesock
mount.cifs //srv/share /mnt/2 -o ...,nosharesock
touch /mnt/1/foo; tail -f /mnt/1/foo & pid=$!

During mount, cifs_mount_get_tcon() gets a tcon resource connection record
and then attaches an fscache volume cookie to it. However, it does this
irrespective of whether or not the tcon returned from cifs_get_tcon() is a
new record or one that's already in use. This leads to a warning about a
volume cookie collision and a leaked volume cookie because tcon->fscache
gets reset.
Fix this be adding a mutex and a "we've already tried this" flag and only
doing it once for the lifetime of the tcon.
[!] Note: Looking at cifs_mount_get_tcon(), a more general solution may
actually be required. Reacquiring the volume cookie isn't the only thing
that function does: it also partially reinitialises the tcon record without
any locking - which may cause live filesystem ops already using the tcon
through a previous mount to malfunction.
This can be reproduced simply by something like:
mount //example.com/test /xfstest.test -o user=shares,pass=xxx,fsc
mount //example.com/test /mnt -o user=shares,pass=xxx,fsc

Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
- Fix a kernel fault during page table walking in huge_pte_alloc() with
PTABLE_LEVELS=5 due to using p4d_offset() instead of p4d_alloc()
- head.S fix and cleanup to disable the MMU before toggling the
HCR_EL2.E2H bit when entering the kernel with the MMU on from the EFI
stub. Changing this bit (currently from VHE to nVHE) causes some
system registers as well as page table descriptors to be interpreted
differently, potentially resulting in spurious MMU faults
- Fix translation fault in swsusp_save() accessing MEMBLOCK_NOMAP
memory ranges due to kernel_page_present() returning true in most
configurations other than rodata_full == true,
CONFIG_DEBUG_PAGEALLOC=y or CONFIG_KFENCE=y

- Fix NULL pointer dereference in program check handler
- Fake IRBs are important events relevant for problem analysis.
Add traces when queueing and delivering
- Fix a race condition in ccw_device_set_online() that can cause the
online process to fail
- Deferred condition code 1 response indicates that I/O was not started
and should be retried. The current QDIO implementation handles a cc1
response as an error, resulting in a failed QDIO setup. Fix that by
retrying the setup when a cc1 response is received

- Fix potential static_command_line buffer overrun. Currently we allocate
the memory for static_command_line based on "boot_command_line", but it
will copy "command_line" into it. So we use the length of "command_line"
instead of "boot_command_line" (as previously we did).
- Use memblock_free_late() in xbc_exit() instead of memblock_free() after
the buddy system is initialized.
- Fix a kerneldoc warning.
