As there is a `rate` field in clk_smd_rpm, clk_smd_rpm_recalc_rate() can
be used by branch clocks to report rate as well, rather than assuming
the rate is always same as parent clock. This assumption doesn't hold
on platforms like QCM2290, where xo_board is 38.4MHz while bi_tcxo is
19.2MHz.
To get this work, XO buffered clocks need the following updates.
- Assign a correct rate rather than the fake one which is being used to
generate binary value for clk_smd_rpm_req interface.
- Explicitly handle the clk_smd_rpm_req interface value for XO buffered
clocks (.rpm_res_type being QCOM_SMD_RPM_CLK_BUF_A).

A previous patch removes the "xo" clock from the global namespace making
it impossible to acquire by that ".name". The device-tree for msm8998
already provides the "xo" and "gpll0" clock since the addition of the

Use parent_data and parent_hws to specify internal relations using

from clock-names in the DT rather than the global clock tree.
Note that this change relies on the "xo" and "sleep_clk" clocks to be

These clocks have been added in a prior patch [1].

Merge tag '5.15-rc-cifs-part2' of git://git.samba.org/sfrench/cifs-2.6
Pull smbfs updates from Steve French:
"cifs/smb3 updates:
- DFS reconnect fix
- begin creating common headers for server and client
- rename the cifs_common directory to smbfs_common to be more
consistent ie change use of the name cifs to smb (smb3 or smbfs is
more accurate, as the very old cifs dialect has long been
superseded by smb3 dialects).
In the future we can rename the fs/cifs directory to fs/smbfs.
This does not include the set of multichannel fixes nor the two
deferred close fixes (they are still being reviewed and tested)"
* tag '5.15-rc-cifs-part2' of git://git.samba.org/sfrench/cifs-2.6:
cifs: properly invalidate cached root handle when closing it
cifs: move SMB FSCTL definitions to common code
cifs: rename cifs_common to smbfs_common
cifs: update FSCTL definitions
vduse driver supporting blk
virtio-vsock support for end of record with SEQPACKET
vdpa: mac and mq support for ifcvf and mlx5
vdpa: management netlink for ifcvf
virtio-i2c, gpio dt bindings
misc fixes, cleanups
NB: when merging this with
b542e383d8 ("eventfd: Make signal recursion protection a task bit")
from Linus' tree, replace eventfd_signal_count with
eventfd_signal_allowed, and drop the export of eventfd_wake_count from
("eventfd: Export eventfd_wake_count to modules").
