clk: shmobile: div6: support selectable-input clocks

2014-11-12T13:24:08+00:00

Support for setting the parent at initialization time based on the current
hardware configuration in DIV6 clocks with selectable parents as found in
the r8a73a4, r8a7740, sh73a0, and other SoCs.

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."

Pull kbuild changes from Michal Marek:
 - fix for handling dependencies of *-objs targets by Masahiro Yamada
 - lots of cleanups in the kbuild machinery, also by Masahiro
 - fixes for the kconfig build to use an UTF-8 capable ncurses library
   if possible and to build on not-so-standard installs
 - some more minor fixes

  kbuild: Do not reference *-n variables in the Makefile
  kbuild: simplify build, clean, modbuiltin shorthands
  kbuild: arm: Do not define "comma" twice
  kbuild: remove obj-n and lib-n handling
  kbuild: remove unnecessary variable initializaions
  kbuild: remove unnecessary "obj- := dummy.o" trick
  kbuild: handle C=... and M=... after entering into build directory
  kbuild: use $(Q) for sub-make target
  kbuild: fake the "Entering directory ..." message more simply
  kconfig/lxdialog: get ncurses CFLAGS with pkg-config

  kbuild: remove redundant clean-files from scripts/kconfig/Makefile
  kbuild: refactor script/kconfig/Makefile
  kbuild: handle the dependency of multi-objs hostprogs appropriately
  kbuild: handle multi-objs dependency appropriately

kbuild: remove unnecessary "obj- := dummy.o" trick

2014-10-02T11:55:02+00:00

In these Makefiles, at least one of "obj-y" and "obj-" is non-empty,
hence built-in.o is always created without such a trick.

clk: shmobile: add missing 0x0100 for SDCKCR

2014-09-02T22:03:16+00:00

(clk: shmobile: Add R-Car Gen2 clocks support)
added R-Car Gen2 clock support via DT for v3.14.

But, cpg_sd01_div_table is missing
"0x0100: x 1/8" division ratio.
This patch fixes hidden bug.
It is based on R-Car H2 v0.7, R-Car M2 v0.9.

clk: shmobile: mstp: Fix the is_enabled() operation

2014-05-23T02:03:03+00:00

The MSTP[SC]R registers have clock stop bits, not clock enable bits. The
bit value should thus be inverted in the is_enabled() operation.

clk: shmobile: r8a7779: Add clocks support

2014-05-13T06:07:40+00:00

The R8A7779 SoC has several clocks that are too custom to be supported in a
generic driver. Those clocks are all fixed rate clocks with multiplier and
divisor set according to boot mode configuration.

Based on work for R-Car Gen2 SoCs by Laurent Pinchart.

clk: shmobile: clk-mstp: change to using clock-indices

2014-05-12T23:53:37+00:00

With the addition of clock-indices, we need to change the renesas
clock implementation to use these instead of the local definition
of "renesas,clock-indices".

Since this will break booting with older device trees, we add a
simple auto-detection of which properties are present.
