soc: qcom: stats: Populate all subsystem debugfs files

2023-03-11T12:50:27+00:00

[ Upstream commit acdbf5f9b2c492505145f6e50c65418521a547c4 ]

This driver relies on SMEM to populate items for each subsystem before
the device probes. The items in SMEM that are being looked for are
populated by the subsystems lazily, and therefore may not exist until
the device has booted. For example, if I build this driver into the
kernel on Trogdor Lazor and boot up, I don't see a 'modem' debugfs file
populated, because the modem boots and populates the SMEM item after
this driver probes.

Always populate the files for the subsystems if they're in SMEM, and
make the qcom_subsystem_sleep_stats_show() function return 0 if the SMEM
items still isn't there. This way we can run a simple command like

	grep ^ /sys/kernel/debug/qcom_stats/*

and collect the subsystem sleep stats without interspersed errors or
missing details entirely because this driver probed first.

soc: qcom: socinfo: Fix soc_id order

2023-03-11T12:50:21+00:00

[ Upstream commit 017a7c11a8a29e266aa40c6d1bf2ba83f880f719 ]

The soc_id array is mostly ordered by the numeric "msm-id" defined in
qcom,ids.h but some recent entries were added at the wrong place.

While it does not make a functional difference it does make it harder
to regenerate the entire array after adding a bunch of new IDs.

PM: AVS: qcom-cpr: Fix an error handling path in cpr_probe()

2023-01-10T15:48:13+00:00

If an error occurs after a successful pm_genpd_init() call, it should be
undone by a corresponding pm_genpd_remove().

Add the missing call in the error handling path, as already done in the
remove function.

soc: qcom: apr: Make qcom,protection-domain optional again

2023-01-06T17:51:19+00:00

APR should not fail if the service device tree node does not have
the qcom,protection-domain property, since this functionality does
not exist on older platforms such as MSM8916 and MSM8996.

Ignore -EINVAL (returned when the property does not exist) to fix
a regression on 6.2-rc1 that prevents audio from working:

  qcom,apr remoteproc0:smd-edge.apr_audio_svc.-1.-1:
    Failed to read second value of qcom,protection-domain
  qcom,apr remoteproc0:smd-edge.apr_audio_svc.-1.-1:
