vexpress: Initialise the sysregs before setting up the clocks

2014-05-04T10:35:29+00:00

Following arm64 commit bc3ee18a7a57 (arm64: init: Move of_clk_init to
time_init()), vexpress_osc_of_setup() is called via of_clk_init() long
before initcalls are issued. Initialising the vexpress oscillators
requires the vespress sysregs to be already initialised, so this patch
adds an explicit call to vexpress_sysreg_of_early_init() in vexpress
oscillator setup function.

clk: vexpress: NULL dereference on error path

2014-04-24T10:39:06+00:00

If the allocation fails then we dereference the NULL in the error path.
Just return directly.

ARM: integrator: localize the impd1.h header

2014-02-26T12:49:06+00:00

As we move toward multiplatform support for the Integrator family
we need to localize all  headers. This moves the impd1.h
header down to the machine folder, copying the the three defines
only used by the clock driver down into the clock driver.

clk: versatile: respect parent rate in ICST clock

2014-02-13T10:20:55+00:00

If the ICST clock has a parent, respect the rate of the parent
when calculating the clock frequency. As this involves modifying
the ICST parameter struct, make a cloned copy (the divisor
arrays should be safe) so we can update the .ref field.

Do not define the reference clock on the Integrator as we have
the reference clock from the device tree. Keep it everywhere
else.

clk: versatile: pass a parent to the ICST clock

2014-02-13T10:20:48+00:00

As we want to actually define the parent frequency in the device
tree for the ICST clocks, modify the clock registration function
to take a parent argument.

ARM: integrator: switch to fetch clocks from device tree

2014-02-13T10:20:42+00:00

This atomic commit changes the Integrator clock implementation
and the machines to register clocks from the device tree and
use these instead of the previous hard-coded clocks.

In the clock implementation all hard-coded clocks and the
special initialization function call goes away, and is
replaced by two compatible strings for the two clocks
available on the core module.

Pull clk framework changes from Mike Turquette:
 "The first half of the clk framework pull request is made up almost
  entirely of new platform/driver support.  There are some conversions
  of existing drivers to the common-clock Device Tree binding, and a few
  non-critical fixes to the framework.

  Due to an entirely unnecessary cyclical dependency with the arm-soc
  tree this pull request is broken into two pieces.  The second piece
  will be sent out after arm-soc sends you the pull request that merged
  in core support for the HiSilicon 3620 platform.  That same pull
  request from arm-soc depends on this pull request to merge in those
  HiSilicon bits without causing build failures"

[ Just did the ARM SoC merges, so getting ready for the second clk tree
  pull request   - Linus ]

clk: versatile: fixup IM-PD1 clock implementation

2014-01-03T21:27:54+00:00

Register both VCO clocks, give per-logical module unique names
to the clocks so we can have several IM-PD1's connected (in
theory). Implement all the fixed-factor clocks as children of
VCO2.

Tested by using the UARTs and the PL181 MMC block on the IM-PD1,
works flawlessly.

clk: versatile: pass a name to ICST clock provider

2014-01-03T21:27:38+00:00

When we have more than one of these clocks in a system (such as
on the IM-PD1) we need a mechanism to pass a name for the clock.
Refactor to add this as an argument.
