Merge tag 'qcom-drivers-for-6.5' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers

Qualcomm driver updates for v6.5

Konrad Dybcio is promoted, from reviewer, to co-maintainer.

The mdt_loader gets a fix to the detection of split binaries, where the
previous logic sometimes concluded that the first segments was not
split, in a split image. The unconditional calling of
scm_pas_mem_setup() turns out to cause a regression and is reverted.

The altmode subfunction of pmic_glink is enabled for SM8450.

A new driver for exposing power statistics from the RPM, for debugging
purposes, is introduced.

OCMEM gets a debug prints of the hardware version, QMI helpers are
transitioned to alloc_ordered_workqueue() and an error message in
ramp_controller is improved.

An API is introduced to the SMEM driver to allow other drivers to query
the SoC id, rather than open-coding the parsing of the relevant SMEM
item. This is then used to clean up the Qualcomm NVMEM-based cpufreq
driver.

Socinfo is extended with knowledge about IPQ5018, IPQ5312 and IPQ5302.

description: |

  The Qualcomm RPM (Resource Power Manager) architecture includes a concept

  of "RPM Masters". They can be thought of as "the local gang leaders", usually

  spanning a single subsystem (e.g. APSS, ADSP, CDSP). All of the RPM decisions

  (particularly around entering hardware-driven low power modes: XO shutdown

  and total system-wide power collapse) are first made at Master-level, and

  only then aggregated for the entire system.



  The Master Stats provide a few useful bits that can be used to assess whether

  our device has entered the desired low-power mode, how long it took to do so,

  the duration of that residence, how long it took to come back online,

  how many times a given sleep state was entered and which cores are actively

  voting for staying awake.



  This scheme has been used on various SoCs in the 2013-2023 era, with some

  newer or higher-end designs providing this information through an SMEM query.
