Qualcomm driver updates for v6.6
Compatible and clock handling in the Qualcomm SCM driver is cleaned up,
together with a couple stylistic cleanups and transition to mark
exported symbols GPL only.
An abstraction for the RPM subsystem is introduced, to make align the
structure of the SMD and GLINK nodes thereof with the structure when a
remoteproc is involved. This is done to facilitate associating
additional entities with the RPM subsystem.
The qmp_send() API is modified to not expose hardware requirements onto
the client drivers, and then further extended to allow command
formatting directly in the API, to facilitate this typical use case.
In the Qualcomm Command DB driver, NUL characters previously included in
identifiers are dropped from the debugfs, to facilitate scripting.
The thresholds of the BWMON driver are simplified to avoid hard coded
starting values.
The OCMEM driver is updated with some cleanups and fixes, and addition
of MSM8226 support.
PMIC_GLINK gains support for retimer switches, safe mode is selected
when the cable is disconnected from altmode and the same is enabled for
SM8550.
An off-by-one string length check is corrected in the QMI encoder
decoder library.
The RPMh tracepoints are extended to include the state of the request,
to provide needed context in the traced events.
The series from Ulf creating a genpd framework is integrated, to
facilitate the other changes to the cpr, rpmpd and rpmhpd driver.
SDX75 support is added to the rpmhpd driver, and the rpmpd driver is
extended with the same sync_state logic found in the rpmhpd driver.
The socinfo driver gains knowledge about SM4450 and SM7125, the IPQ5019
platform is dropped.
Clock handling in the GSBI driver is cleaned up with the use of
devm_clk_get_enabled().
The list of VMIDs defined for the SCM assign memory interface is
extended.

firmware: arm_scmi: Add v3.2 perf level indexing mode support
SCMI v3.2 adds PERF protocol support to optionally define performance
domains that cannot be represented on a linear scale; the platform firmware
can declare the performance levels of a domain as being 'level indexed' and
provide an indicative frequency associated to each of those levels, with
such indexes not required anymore to be contiguous nor to satisfy any
linear-scaling constraint: when level-indexing is available for a domain,
the platform will expect to deal with SCMI requests using indexes instead
of performance levels for that domain.
Add level-indexing mode support to the PERF protocol implementation while
maintaining unchanged the protocol operations interface exposed by PERF;
all the required mapping from performamce levels/frequencies to the
corresponding level indexes is carried out transparently by the core PERF
protocol support: as a consequence no change is either required in any
SCMI driver using the PERF protocol, even when using level indexing.
MAINTAINERS: Simplify entries for Arm Vexpress platform and related drivers
Currently the entries have regexs but in absolute paths. The "N:" entries
can deal with all files and directories irrespective of the depth/path
matching the regex patterns.
Simplifies the entry by making using "N:" and dropping "F:" with absolute
paths.
