This is series has two parts. The first two patches are changes
to the existing Broadcom Kona family clock code to prepare for the
addition of support for another SoC, bcm21664.
The remaining three define the binding and code for bcm21664, and
replace the use of "fake" clocks in the device tree with the real
ones. This ends up being a fairly straightforward definition of
the clocks on this SoC; the rest of the clock code is shared with
other SoCs that use the Kona style clock system.
This series depends on the following patch, which has been taken
into the clk-fixes tree:
clk: bcm281xx: don't use unnamed structs or unions
https://lkml.org/lkml/2014/4/7/322
In addition, it depends on the version 4 of the following series,
just (re)posted for review:
clk: bcm281xx: updates
https://lkml.org/lkml/2014/4/8/485
The patches in this series--based on the current linus/master branch
plus the patches mentioned above--are available here:

The Broadcom 281xx clock code uses a #define for the compatible
string for it's clock control units (CCUs). Rather than defining
those in the C source file, define them in the header file that's
shared by both the code and the device tree source file (along with
all the clock ids).

The next patch defines a binding for a new Broadcom SoC that uses
Kona style CCUs for its clocks. Update the generic Kona clock
binding document so it's more natural to accomodate the definitions
of additional SoC families.
Specifically:
- Define the compatible string values generically, referring
to specific per-model values later in the document.
- Put the device tree example immediately after the required
properties listing, before the tables of SoC-specific values.
- Clearly identify the start of the section defining specific
values related to the BCM281XX family
- Add a list of the specific BCM281XX family compatible strings.
- Reword the description of the table slightly.

* [PATCH v2 RESEND 2/5] ARM: dts: revise kona clock binding document
@ 2014-04-21 21:26 ` Alex Elder
0 siblings, 0 replies; 27+ messages in thread
From: Alex Elder @ 2014-04-21 21:26 UTC (permalink / raw)
To: linux-arm-kernel
The next patch defines a binding for a new Broadcom SoC that uses
Kona style CCUs for its clocks. Update the generic Kona clock
binding document so it's more natural to accomodate the definitions
of additional SoC families.
Specifically:
- Define the compatible string values generically, referring
to specific per-model values later in the document.
- Put the device tree example immediately after the required
properties listing, before the tables of SoC-specific values.
- Clearly identify the start of the section defining specific
values related to the BCM281XX family
- Add a list of the specific BCM281XX family compatible strings.
- Reword the description of the table slightly.

Define the set of CCUs and provided clocks sufficient to satisfy the
needs of all the existing clock references for BCM21664. Replace
the "fake" fixed-rate clocks used previously with "real" ones.
Note that only the minimal set of these clocks and CCUs is defined
here. More clock definitions will need to be added as required by
the addition of additional drivers.

* [PATCH v2 RESEND 4/5] clk: bcm21664: use common clock framework
@ 2014-04-21 21:26 ` Alex Elder
0 siblings, 0 replies; 27+ messages in thread
From: Alex Elder @ 2014-04-21 21:26 UTC (permalink / raw)
To: linux-arm-kernel
Define the set of CCUs and provided clocks sufficient to satisfy the
needs of all the existing clock references for BCM21664. Replace
the "fake" fixed-rate clocks used previously with "real" ones.
Note that only the minimal set of these clocks and CCUs is defined
here. More clock definitions will need to be added as required by
the addition of additional drivers.

Hi Alex,
I'm happy to take only the clk patches or I can take the DT stuff as
well if it gets some Acks. Let me know how you want it handled.

If all you need is an ack from Matt or Christian I'm
sure they'll provide it. I don't care much but if
you'll take it all I can just consider it done, so
that would be my slight preference. The DT stuff has
been out there for way past the requisite few weeks...
Thanks Mike.

Hi Mike,
Since there's a strict ordering requirement in this series (due to
shared use of a DT include by the driver and dts) I'd like it if you
could take the entire series through your tree to keep these together.
I've acked the dts patch.
Thanks,
Matt

No problem. Taken into clk-next with your Ack added to patch #5.
