Hi,
this series introduces the support for a new generic SCMI Regulator driver
developed on top of the recently introduced SCMI Voltage Domain Protocol
support as specified in the upcoming SCMIv3.0 specification. [1]
The underlying SCMI VD Protocol support, which was originally part of this
series, is now applied on for-next/scmi-voltage [2], and this series,
reduced to its SCMI Regulator support and dt-bindings fixes is similarly
based on top of [2]:
commit ec8838193695 ("firmware: arm_scmi: Add support to enumerated SCMI
voltage domain device")
Thanks,
Cristian
---
v6 --> v7
- rebased on top of for-next/scmi-voltage
- added dt-bindings fix to remove optional properties
- add proper blank lines between semantic blocks
- fix return value on error path of scmi_reg_is_enabled()
- use generic Failure message on err path of info_get()
- fix comment containing apostrophe
v5 --> v6
- reordered dt bindings patch
- removed single field struct
- reviewed args to scmi_init_voltage_levels()
- allocating scmi_voltage_info_array contiguously
v4 --> v5
- rebased
- VD Protocol
- removed inline
- moved segmented intervals defines
- fixed some macros complaints by checkpatch
v3 --> v4
- DT bindings
- using generic node names
- listing explicitly subset of supported regulators bindings
- SCMI Regulator
- using of_match_full_name core regulator flag
- avoid coccinelle false flag complaints
- VD Protocol
- avoid coccinelle false flag complaints
- avoiding fixed size typing
v2 --> v3
- DT bindings
- avoid awkard examples based on _cpu/_gpu regulators
- SCMI Regulator
- remove multiple linear mappings support
- removed duplicated voltage name printout
- added a few comments
- simplified return path in scmi_reg_set_voltage_sel()
- VD Protocol
- restrict segmented voltage domain descriptors to one triplet
- removed unneeded inline
- free allocated resources for invalid voltage domain
- added __must_check to info_get voltage operations
- added a few comments
- removed fixed size typing from struct voltage_info
v1 --> v2
- rebased on for-next/scmi v5.10
- DT bindings
- removed any reference to negative voltages
- SCMI Regulator
- removed duplicate regulator naming
- removed redundant .get/set_voltage ops: only _sel variants implemented
- removed condexpr on fail path to increase readability
- VD Protocol
- fix voltage levels query loop to reload full cmd description
between iterations as reported by Etienne Carriere
- ensure transport rx buffer is properly sized calli scmi_reset_rx_to_maxsz
between transfers
