[PATCH 0/3] spmi: Add SmartDV SPMI controller driver and bindings

[vamshi gajjela <vamshigajjela@google.com>]

From: Vamshi Gajjela <vamshigajjela@google.com>

This series adds Device Tree bindings and a controller driver for the
SmartDV IP Solutions MIPI System Power Management Interface (SPMI) master
controller ("smartdv,spmi").

This IP is integrated in Google Tensor SoCs starting with the G5
generation (codename: laguna, canonically written as "lga",
"google,lga-spmi") to communicate with on-board Power Management ICs
(PMICs).

The controller supports MIPI SPMI v1.0 and v2.0 non-data bus commands
(RESET, SLEEP, SHUTDOWN, WAKEUP), register read/write, extended register
read/write, and extended register read/write long transfers up to 16 bytes.

Patch 1/3 adds the "smartdv" vendor prefix to vendor-prefixes.yaml.
Patch 2/3 documents the Device Tree bindings for the SmartDV SPMI
controller ("smartdv,spmi" and "google,lga-spmi").
Patch 3/3 adds the spmi-smartdv controller driver.
