Message-ID<ssDrj-45V-5@gated-at.bofh.it>
Hi,

This serie is a preparation to shift the cpufreq of pxa2xx platforms to clocks
API.

The first 3 patches are review and merge material :
 - patch 1/4 for Viresh and Rafael
 - patches 2/4 and 3/4 for me

The 4th on is for review but not merge, as the clock changes must be fully
reviewed and go in first as a prequisite

Robert Jarzmik (4):
  cpufreq: pxa: use generic platdev driver for device-tree
  ARM: dts: pxa: add pxa25x cpu operating points
  ARM: dts: pxa: add pxa27x cpu operating points
  cpufreq: pxa: convert to clock API

 arch/arm/boot/dts/pxa25x.dtsi        |  25 +++++

Have you tested whether this patch set results in functional cpufreq
support - looking at drivers/clk/pxa, the CPU clock is read-only -
it can't be used to change the clock rate.  So, I very much doubt this
has been functionally tested.

Don't forget that changing the CPU clock rate needs other changes
(like the memory clock rate) so all that code you're removing in
patch 4 (which does the actual clock change) needs to go somewhere.

Oh yes I did, on lubbock and mainstone ... but this requires another patchset
under review, here :

Sure, here :
https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1247130.html

I would have been wiser to quote these URLs instead of speaking of "clock
changes must be fully review and go in first as a prequisite".

Cheers.

Guys,

Looks like gmail's been hacked (or something).  Within 50 minutes of
sending the reply below, I've received at least 10 replies with the
following headers:

In-Reply-To: <20161015203421.GG1041@n2100.armlinux.org.uk>
References: <1476561450-28407-1-git-send-email-robert.jarzmik@free.fr> <20161015203421.GG1041@n2100.armlinux.org.uk>

from various gmail.com addresses, each and every one containing some kind
of spam.  Each reply is from a victim of spam - the replies themselves are
people replying to the spam that they have received.  The quoted message
is allegedly from me, and even includes the line:

 "On 15 Oct 2016, at 21:34, Russell King - ARM Linux <linux@armlinux.org.uk>
 wrote:"

which is the time I sent the original message.

It's either that gmail has been hacked, or one of the mailing lists in
the recipients of this message has been hacked.
