clk: si5351: make clk-si5351 depend on CONFIG_OF

2013-04-16T04:42:56+00:00

Calling clk-si5351 driver non-OF ready was too early. This patch
makes clk-si5351 depend on CONFIG_OF again, until things get sorted out.

clk: add si5351 i2c common clock driver

2013-04-12T18:04:38+00:00

This patch adds a common clock driver for Silicon Labs Si5351a/b/c
i2c programmable clock generators. Currently, the driver does not
support VXCO feature of si5351b. Passing platform_data or DT bindings
selectively allows to overwrite stored Si5351 configuration which is
very helpful for clock generators with empty eeprom configuration.
Corresponding device tree binding documentation is also added.

clk: Add axi-clkgen driver

2013-03-20T00:20:30+00:00

This driver adds support for the AXI clkgen pcore to the common clock framework.
The AXI clkgen pcore is a AXI front-end to the MMCM_ADV frequency synthesizer
commonly found in Xilinx FPGAs.

The AXI clkgen pcore is used in Analog Devices' reference designs targeting
Xilinx FPGAs.

Merge tag 'mvebu' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2012-12-14T22:54:26+00:00

Pull ARM SoC updates for Marvell mvebu/kirkwood from Olof Johansson:
 "This is a branch with updates for Marvell's mvebu/kirkwood platforms.
  They came in late-ish, and were heavily interdependent such that it
  didn't make sense to split them up across the cross-platform topic
  branches.  So here they are (for the second release in a row) in a
  branch on their own."

clk: mvebu: add mvebu core clocks.

2012-11-20T13:34:08+00:00

This driver allows to provide DT clocks for core clocks found on
Marvell Kirkwood, Dove & 370/XP SoCs. The core clock frequencies and
ratios are determined by decoding the Sample-At-Reset registers.

Although technically correct, using a divider of 0 will lead to
div_by_zero panic. Let's use a ratio of 0/1 instead to fail later
with a zero clock.

clk: Common clocks implementation for Versatile Express

2012-10-29T18:08:03+00:00

This patch adds a DT and non-DT based implementation of
the common clock infrastructure for Versatile Express
platform. It registers (statically or using DT) all
required fixed clocks, initialises motherboard's SP810
cell (that provides clocks for SP804 timers) and
explicitly registers VE "osc" driver, to make the
clock generators available early.

CLK: clk-twl6040: Initial clock driver for OMAP4+ McPDM fclk clock

2012-10-29T18:07:42+00:00

On OMAP4+ platforms the functional clock for the McPDM IP is suplied by
the twl6040 codec (bit clock on the PDM bus).
This common clock driver for twl6040 will register the mcpdm_fclk clock to
be used by the McPDM driver to make sure that the needed clocks are
available when needed.

clock: max77686: Add driver for Maxim 77686 32Khz crystal oscillator.

2012-09-06T23:55:38+00:00

This patch supports max77686 mfd's clock driver using common clock frame work.
max77686 has 3 clock ouputs which all are generated from crystal oscillator and
SOC can enable/disable them via I2C bus. All clocks are fixed-rate clock sources
so that it doesn't supply interface for changing clock rate.
Driver uses regmap API to communicate with internal register.

clk: versatile: make config option boolean

There is no choice to have the RealView clocks as module for sure,

clk: convert ARM RealView to common clk

2012-08-25T00:42:10+00:00

This converts the ARM RealView machine over to using the common
clock. The approach is similar to the one used for the Integrator,
and we're reusing the ICST wrapper code.

We have to put the clock intialization in the timer init function
for the clocks to be available when initializing the timer,
keeping them in early_init() is too early for the common clk.

Since we now have to go down and compile drivers/clk/versatile
a CONFIG_COMMON_CLK_VERSATILE symbol has been added so the proper
code gets compiled into the kernel for either machine. A leftover
CLK_VERSATILE in the Integrator Kconfig was fixed up to use
the new symbol as well.

Tested on ARM RealView PB1176.
