Subject: Raspberry Pi DT clocks series
Date: Mon, 18 May 2015 12:43:32 -0700 [thread overview]
Message-ID: <1431978219-14226-1-git-send-email-eric@anholt.net> (raw)
Here's a series to add a real clock provider on Raspberry Pi.
Previously, we've been using a mix of fixed clocks from clk-bcm2835.c
(though some of them failed to get used by their intended consumers),
and fixed-clock nodes in the DT.
This driver gives us the ability to enable/disable our clocks, and
also lets us get and set frequency values. This will let us build a
cpufreq driver (Andrea Merello has done some work on this front, and
has a couple of options available), and get correct frequencies on the
Raspberry Pi 2 without hardcoding new values.
This branch can be found at:
https://github.com/anholt/linux/tree/rpi-dt-clocks
which also has a patch for the MMC clock which is not included yet due
to a bug in the sdhci driver. The series applies on top of
rpi-mailbox, whose code is currently out for review:
