Merge tag 'clk-for-linus-3.18' of git://git.linaro.org/people/mike.turquette/linux

2014-10-15T05:05:03+00:00

Pull clock tree updates from Mike Turquette:
 "The clk tree changes for 3.18 are dominated by clock drivers.  Mostly
  fixes and enhancements to existing drivers as well as new drivers.
  This tag contains a bit more arch code than I usually take due to some
  OMAP2+ changes.  Additionally it contains the restart notifier
  handlers which are merged as a dependency into several trees.

  The PXA changes are the only messy part.  Due to having a stable tree
  I had to revert one patch and follow up with one more fix near the tip
  of this tag.  Some dead code is introduced but it will soon become
  live code after 3.18-rc1 is released as the rest of the PXA family is
  converted over to the common clock framework.

  Another trend in this tag is that multiple vendors have started to
  push the complexity of changing their CPU frequency into the clock
  driver, whereas this used to be done in CPUfreq drivers.

  Changes to the clk core include a generic gpio-clock type and a
  clk_set_phase() function added to the top-level clk.h api.  Due to
  some confusion on the fbdev mailing list the kernel boot parameters
  documentation was updated to further explain the clk_ignore_unused
  parameter, which is often required by users of the simplefb driver.

  Finally some fixes to the locking around the clock debugfs stuff was
  done to prevent deadlocks when interacting with other subsystems."

clk: RK808: add clkout driver for RK808

2014-10-14T00:18:18+00:00

This is the initial version of the RK808 PMIC.  This is a power management
IC for multimedia products.  It provides regulators that are able to
supply power to processor cores and other components.  The chip provides
other modules including RTC, Clockout.

clk: pxa clocks build system fix

2014-10-05T20:41:53+00:00

Fix the building of pxa clock drivers so that the files are actually
compiled if and only if COMMON_CLK was selected by the architecture.

This prevents conflicts with mach-pxa clock legacy implementation.

clk: Add driver for Maxim 77802 PMIC clocks

2014-09-09T20:55:59+00:00

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

clk: max77686: Convert to the generic max clock driver

2014-09-09T20:55:49+00:00

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.

clk: Add generic driver for Maxim PMIC clocks

2014-09-09T20:55:44+00:00

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.

clk: Add driver for Palmas clk32kg and clk32kgaudio clocks

2014-07-02T04:37:57+00:00

Palmas class of devices can provide 32K clock(s) to be used by other devices
on the board. Depending on the actual device the provided clocks can be:
CLK32K_KG and CLK32K_KGAUDIO
or only one:
CLK32K_KG (TPS659039 for example)

Use separate compatible flags for the two 32K clock.
A system which needs or have only one of the 32k clock from
Palmas will need to add node(s) for each clock as separate section
in the dts file.
The two compatible property is:
"ti,palmas-clk32kg" for clk32kg clock
"ti,palmas-clk32kgaudio" for clk32kgaudio clock

Apart from the register control of the clocks - which is done via
the clock API there is a posibility to enable the external sleep
control. In this way the clock can be enabled/disabled on demand by the
user of the clock.

See the documentation for more details.

Merge tag 'clk-for-linus-3.16' of git://git.linaro.org/people/mike.turquette/linux into next

2014-06-08T03:27:30+00:00

Pull clock framework updates from Mike Turquette:
 "The clock framework changes for 3.16 are pretty typical: mostly clock
  driver additions and fixes.  There are additions to the clock core
  code for some of the basic types (e.g. the common divider type has
  some fixes and featured added to it).

  One minor annoyance is a last-minute dependency that wasn't handled
  quite right.  Commit ba0fae3b06a6 ("clk: berlin: add core clock driver
  for BG2/BG2CD") in this pull request depends on
  include/dt-bindings/clock/berlin2.h, which is already in your tree via
  the arm-soc pull request.  Building for the berlin platform will break
  when the clk tree is built on it's own, but merged into your master
  branch everything should be fine"
