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.

Merge branch 'clk-pxa27x' into clk-next

clk: add pxa clocks infrastructure

2014-09-30T19:31:30+00:00

Add a the common code used by all PXA variants.

This is the first step in the transition from architecture defined
clocks (in arch/arm/mach-pxa) towards clock framework. The goal is to
have the same features (and not all the features) of the existing
clocks, and enable the transition of PXA to device-tree.

All PXA rely on a "CKEN" type clock, which :
 - has a gate (bit in CKEN register)
 - is generated from a PLL, generally divided
 - has an alternate low power clock

Each variant will specialize the CKEN clock :
 - pxa25x have no low power clock
 - pxa27x in low power use always the 13 MHz ring oscillator
 - pxa3xx in low power have specific dividers for each clock

The device-tree provides a list of CLK_* (ex: CLK_USB or CLK_I2C) to get
a handle on the clock. While pxa-clock.h will describe all the clocks of
all the variants, each variant will only use a subset of it.

clk: add gpio gated clock

2014-09-26T23:51:42+00:00

The added gpio-gate-clock is a basic clock that can be enabled and
disabled trough a gpio output. The DT binding document for the clock
is also added. For EPROBE_DEFER handling the registering of the clock
has to be delayed until of_clk_get() call time.

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

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: Support for clock parents and rates assigned from device tree

2014-07-25T22:16:27+00:00

This patch adds helper functions to configure clock parents and rates
as specified through 'assigned-clock-parents', 'assigned-clock-rates'
DT properties for a clock provider or clock consumer device.
The helpers are now being called by the bus code for the platform, I2C
and SPI busses, before the driver probing and also in the clock core
after registration of a clock provider.
