clk: si5351: fix .recalc_rate for multisynth 6-7

2015-05-13T18:52:06+00:00

MS6 and MS7 do not have the MSx_P3 field. Do the 'params.p3 == 0'
check for MS0-M5 only. See [AN619, p. 6] for details.

clk: si5351: fix .round_rate for multisynth 6-7

2015-05-13T18:52:05+00:00

The divider calculation for multisynth 6 and 7 differs from the
calculation for multisynth 0-5.

For MS6 and MS7, set MSx_P1 directly, MSx_P1=divide value
[AN619, p. 6].

clk: si5351: Do not pass struct clk in platform_data

2015-05-08T18:22:30+00:00

When registering clk-si5351 by platform_data, we should not pass struct clk
for the reference clocks. Drop struct clk from platform_data and rework the
driver to use devm_clk_get of named clock references.

While at it, check for at least one valid input clock and properly prepare/
enable valid reference clocks.

clk: si5351: Constify clock names and struct regmap_config

2015-03-27T07:21:39+00:00

The regmap_config struct may be const because it is not modified by the
driver and regmap_init() accepts pointer to const.

Replace doubled const in the arrays of clock names with proper const
pointer to const data. This fixes the warnings:

drivers/clk/clk-si5351.c:71:25: warning: duplicate const

Pull more clock framework changes from Mike Turquette:
 "The second half of the clock framework pull requeust for 3.14 is
  dominated by platform support for Qualcomm's MSM SoCs, DT binding
  updates for TI's OMAP-ish processors and additional support for
  Samsung chips.

  Additionally there are other smaller clock driver changes and several
  last minute fixes.  This pull request also includes the HiSilicon
  support that depends on the already-merged arm-soc pull request"

clk: si5351: remove variant from platform_data

2014-01-27T19:20:22+00:00

Commit 9807362bfe1748d9bb48eecb9261f1b1aaafea1c
  "clk: si5351: declare all device IDs for module loading"
removed the common i2c_device_id and introduced new ones for each variant
of the clock generator. Instead of exploiting that information in the driver,
it still depends on platform_data passing the chips .variant.

This removes the now redundant .variant from the platform_data and puts it in
i2c_device_id's .driver_data instead.

Pull clock framework updates from Mike Turquette:
 "The common clock framework changes for 3.11 include new clock drivers
  across several different platforms and architectures, fixes to
  existing drivers, a MAINTAINERS file fix and improvements to the basic
  clock types that allow them to be of use to more platforms than before.

  Only a few fixes to the core framework are included with most all of
  the changes landing in the various clock drivers themselves."

clk: si5351: declare all device IDs for module loading

2013-05-29T05:50:32+00:00

When the si5351 driver is a kernel module, it is loaded into memory
from its i2c device IDs, but not from its DT compatible properties.

This patch declares the i2c device IDs of all chip variants.
