ARM: OMAP2+: clock: fix DPLL code to use new determine rate APIs

2014-12-16T01:05:08+00:00

While the change for determine_rate clock operation was merged,
the OMAP counterpart using these calls was overlooked for some reason,
and caused boot failures on at least OMAP4 platforms. Fixed by updating
the DPLL API calls to use the new parameters.

ARM: OMAP3: clock: add support for dpll4_set_rate_and_parent

2014-11-13T16:26:33+00:00

Expand the support of omap4 per-dpll to provide set_rate_and_parent.
This is required for proper behavior of clk_change_rate with
determine_rate support.

ARM: OMAP4: clock: add support for determine_rate for omap4 regm4xen DPLL

2014-11-13T16:26:25+00:00

Similarly to OMAP3 noncore DPLL, the implementation of this DPLL clock
type is wrong. This patch adds basic functionality for determine_rate
for this clock type which will be taken into use in the patches following
later.

ARM: OMAP3: clock: add new rate changing logic support for noncore DPLLs

2014-11-13T16:26:16+00:00

Currently, DPLL code hides the re-parenting within its internals, which
is wrong. This needs to be exposed to the common clock code via
determine_rate and set_rate_and_parent APIs. This patch adds support
for these, which will be taken into use in the following patches.

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: ti: change clock init to use generic of_clk_init

2014-09-29T08:51:13+00:00

Previously, the TI clock driver initialized all the clocks hierarchically
under each separate clock provider node. Now, each clock that requires
IO access will instead check their parent node to find out which IO range
to use.

This patch allows the TI clock driver to use a few new features provided
by the generic of_clk_init, and also allows registration of clock nodes
outside the clock hierarchy (for example, any external clocks.)

clk: at91: add a driver for the h32mx clock

2014-09-22T09:38:59+00:00

Newer SoCs have two different AHB interconnect. The AHB 32 bits Matrix
interconnect (h32mx) has a clock that can be setup at the half of the h64mx
clock (which is mck). The h32mx clock can not exceed 90 MHz.

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.

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"
