Subject: [PATCH] bcm2835: Add Raspberry Pi CPU frequency control to the device tree
Date: Sun, 11 Oct 2015 21:46:35 +0200	[thread overview]
Message-ID: <1444592795-15129-1-git-send-email-lkundrak@v3.sk> (raw)

This adds a device tree binding for Broadcom BCM2834 CPU frequency control
driven via Raspberry Pi VideoCore 4 firmware interface.

Depends on the RPi Firmware driver submitted on linux-rpi-kernel a while ago. 
Can't see it in arm-soc or linux-next yet though (?). Available in branch 
'rpi-firmware' of https://github.com/anholt/linux
