Hello Mike,
This series add support for the clocks present in the Maxim
77802 Power Managment IC. Previously, the series was part
of a bigger one [0] that aimed to add support for all the
devices in the max77802 PMIC. But now the Maxim 77802 PMIC
dependencies were already merged for 3.17 so the series can
be split and each driver can go through the relevant tree.
The support needed for the clocks in the max77802 is very
similar to the one for the ones in the max77686 so a generic
driver was added that allows to remove the duplicated code
for both drivers. Patch 01/06 adds a dt binding include that
can be used to share the max77686 clocks between the driver
and the DTS files. Patch 02/06 adds the generic clock driver
for maxim pmic clocks and patch 03/06 converts the existing
max77686 clock driver to the generic one. Patch 04/06 adds
some improvements to the max77686 clock driver DT binding.
Patch 05/06 adds the max77802 clock driver and finally patch
06/06 adds the DT binding documentation for this driver.
I kept the version numbering from the old series so this is
version 9 although there were no changes on the max77802 clock
driver since v5 of the old series and all the patches had been
already acked by you so I hope there won't be issues to get
them merged.
The series were tested on an Exynos5250 Snow (max77686) and
Exynos5420 Peach Pit (max77802) machines and applies cleanly
to both 3.17-rc1 and today's linux-next (20140818).

Maxim Integrated Power Management ICs are very similar with
regard to their clock outputs. Most of the clock drivers for
these chips are duplicating code and are simpler enough that
can be converted to use a generic driver to consolidate code
and avoid duplication.

Changes since v6: None
Changes since v5:
- Fix generic driver changes merged into max77802 clock patch by mistake.
Suggested by Yadwinder Singh Brar.
- Register clock lookups using clk_register_clkdev() instead of doing manually.
- Use the managed devm_clk_register() function and remove clk un-registration.
- Add "clock-output-names" property support. Suggested by Yadwinder Singh Brar.
- Return the rate unconditionally in recalc_rate. Suggested by Mike Turquette.
Changes since v4: None
Changes since v3:
- Don't change clock-names property to make clear that it's
the consumer clock name and should not match the producer clock.
Suggested by Doug Anderson.

Maxim Integrated Power Management ICs are very similar with
regard to their clock outputs. Most of the clock drivers for
these chips are duplicating code and are simpler enough that
can be converted to use a generic driver to consolidate code
and avoid duplication.

Changes since v6: None
Changes since v5:
- Fix generic driver changes merged into max77802 clock patch by mistake.
Suggested by Yadwinder Singh Brar.
- Register clock lookups using clk_register_clkdev() instead of doing manually.
- Use the managed devm_clk_register() function and remove clk un-registration.
- Add "clock-output-names" property support. Suggested by Yadwinder Singh Brar.
- Return the rate unconditionally in recalc_rate. Suggested by Mike Turquette.
Changes since v4: None
Changes since v3:
- Don't change clock-names property to make clear that it's
the consumer clock name and should not match the producer clock.
Suggested by Doug Anderson.

Clocks drivers for Maxim PMIC are very similar so they can
be converted to use the generic Maxim clock driver.
Also, while being there use module_platform_driver() helper
macro to eliminate more boilerplate code.

* [PATCH v9 3/6] clk: max77686: Convert to the generic max clock driver

Clocks drivers for Maxim PMIC are very similar so they can
be converted to use the generic Maxim clock driver.
Also, while being there use module_platform_driver() helper
macro to eliminate more boilerplate code.

Like most clock drivers, the Maxim 77686 PMIC clock binding
follows the convention that the "#clock-cells" property is
used to specify the number of cells in a clock provider.
But the binding document is not clear enough that it shall
be set to 1 since the PMIC support multiple clocks outputs.
Also, explain that the clocks identifiers are defined in a
header file that can be included by Device Tree source with
client nodes to avoid using magic numbers.
Finally, add "clock-output-names" as an optional property
since now is supported by the clock driver.

Changes since v5:
- Fix generic driver changes merged into max77802 clock patch by mistake.
Suggested by Yadwinder Singh Brar.
- Register clock lookups using clk_register_clkdev() instead of doing manually.
- Use the managed devm_clk_register() function and remove clk un-registration.
- Add "clock-output-names" property support. Suggested by Yadwinder Singh Brar.
- Return the rate unconditionally in recalc_rate. Suggested by Mike Turquette.
Changes since v4: None
Changes since v3:
- Don't change clock-names property to make clear that it's
the consumer clock name and should not match the producer clock.
Suggested by Doug Anderson.

The MAX77802 PMIC has two 32.768kHz Buffered Clock Outputs with
Low Jitter Mode. This patch adds support for these two clocks.

Changes since v5: None
Changes since v4: None
Changes since v3: None
Changes since v2: None
Changes since v1:
- Use module_platform_driver() instead of having init/exit functions.
Suggested by Mark Brown.
- Use the generic maxim clock driver to reduce code duplication with
clk-max77686.c driver.

Add Device Tree binding documentation for the clocks

Changes since v6: None
Changes since v5:
- Fix typo error in DT binding. Suggested by Andreas Farber.
- Add "clock-output-names" as an optional property since now is supported.
Changes since v4: None
Changes since v3:
- Don't use the same clock driver name in clock-names since it's a consumer
concept and most probably will be different. Suggested by Doug Anderson.
Changes since v2:
- Split the DT binding documentation in a separate patch.

* [PATCH v9 6/6] clk: max77802: Add DT binding documentation
@ 2014-08-18 8:33 ` Javier Martinez Canillas

Add Device Tree binding documentation for the clocks
outputs in the Maxim 77802 Power Management IC.
Signed-off-by: Javier Martinez Canillas <javier.martinez@collabora.co.uk>
Acked-by: Mike Turquette <mturquette@linaro.org>
---
Changes since v6: None
Changes since v5:
- Fix typo error in DT binding. Suggested by Andreas Farber.
- Add "clock-output-names" as an optional property since now is supported.
Changes since v4: None
Changes since v3:
- Don't use the same clock driver name in clock-names since it's a consumer
concept and most probably will be different. Suggested by Doug Anderson.
Changes since v2:
- Split the DT binding documentation in a separate patch.

+Binding for Maxim MAX77802 32k clock generator block
+
+This is a part of device tree bindings of MAX77802 multi-function device.
+More information can be found in bindings/mfd/max77802.txt file.
+
+The MAX77802 contains two 32.768khz clock outputs that can be controlled
+(gated/ungated) over I2C.
+
+Following properties should be present in main device node of the MFD chip.
+
+Required properties:
+- #clock-cells: From common clock binding; shall be set to 1.
+
+Optional properties:
+- clock-output-names: From common clock binding.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. Following indices are allowed:
+ - 0: 32khz_ap clock,
+ - 1: 32khz_cp clock.
+
+Clocks are defined as preprocessor macros in dt-bindings/clock/maxim,max77802.h
+header and can be used in device tree sources.
+
+Example: Node of the MFD chip
+
+ max77802: max77802 at 09 {
+ compatible = "maxim,max77802";
+ interrupt-parent = <&wakeup_eint>;
+ interrupts = <26 0>;
+ reg = <0x09>;
+ #clock-cells = <1>;
+
+ /* ... */
+ };
+
+Example: Clock consumer node
+
+ foo at 0 {
+ compatible = "bar,foo";
+ /* ... */
+ clock-names = "my-clock";
+ clocks = <&max77802 MAX77802_CLK_32K_AP>;
+ };

This series was first posted for 3.17 and you acked the whole set but
it missed 3.17 because had as a dependency some changes in the
max77802 mfd driver. Those dependencies made for 3.17 and that's why I
re-posted it for 3.18 about a month ago.
Since we are in 3.17-rc4 already, I'm afraid that this series may miss
3.18 again, is there anything else you need from me to pick this
series? It will obviously conflict with Tomeu's "Per-user clock
constraints" series [0] so if you want I can rebase it on top of your
clk-next-tomeu-kirkwood-v2 branch [1].
Thanks a lot and best regards,
Javier

Thanks for pinging me about it. I've pulled this series into clk-next
for 3.18. Everything is going to conflict with Tomeu's series so we'll
just handle that when it comes to merge his series (which I've since
removed from clk-next due to pending issues).
