Subject: [PATCH v2 0/4] Add support for SCMIv3.0 Voltage Domain Protocol and SCMI-Regulator
Date: Thu, 15 Oct 2020 16:39:57 +0100	[thread overview]
Message-ID: <20201015154001.8931-1-cristian.marussi@arm.com> (raw)

Hi,

this series introduces the support for the new SCMI Voltage Domain Protocol
defined by the upcoming SCMIv3.0 specification, whose BETA release is
available at [1].

Afterwards, a new generic SCMI Regulator driver is developed on top of the
new SCMI VD Protocol.

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

commit fd7c58ee3026 ("firmware: arm_scmi: Fix locking in notifications")

Any feedback welcome,

Thanks,

Cristian

---
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
