Description

The Linux kernel contains a regulator framework for instantiating and managing voltage regulators used during Dynamic Frequency and Voltage Scaling (DVFS) operations. ARM SOC ports currently hardcode board-specific regulator information in the board.c file. As part of the transition to using Device Tree for board initialisation, Linaro engineering will lead development of device tree bindings for this framework along with porting of device drivers and BSPs to using DT. This work includes:

Acceptance criteria

All code is merged upstream into Linus' tree
Kernel can boot across all Linaro member LEBs with regulators fully described via device tree

Existing user space applications and test suites that interface with system regulators run correctly
