[PATCH v4 0/6] SCMIv3.0 Sensor Extensions

[Cristian Marussi <cristian.marussi@arm.com>]

Hi,

this series is meant to add support for the new SCMI Sensor Protocol
features defined by the upcoming SCMIv3.0 specification, whose BETA
release is available at [1].

The series is currently based on for-next/scmi [2] on top of:

commit b141fca08207 ("firmware: arm_scmi: Fix missing destroy_workqueue()")

Any feedback welcome,

Thanks,

Cristian

---
v3 --> v4
- dropped multiple single field structs
- dropped _le structs naming
- hardcoded a few defines for base sz structs
- introduced SCMIv2 version define to use for comparisons
  and fixed a few comments
- drop to _dbg prints about missing interval update info
- dropped SCMIv3 unrelated comment fix

v2 --> v3
- removed stale unused msg payload definition
- moved variable declaration inside switch block
- setting rx_size to 0 in sensor_reading_get to allow fw to send
  both v2 and v3 replies...even if sensor_reading_get() only handles
  v2 spec and returns one single value
- using get_unaligned_le64 in lieu of le64_to_cpu
- removed refs to v2.1
- Fix SCMI_MAX_NUM_SENSOR_AXIS to 63
- added missing Dox comment in resolution
- added common INTVL SEGMENT macros

v1 --> v2
- rebased on for-next/scmi v5.10
- restrict segmented intervals descriptors to single triplet
- add proper usage of scmi_reset_rx_to_maxsz
