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." * tag 'clk-for-linus-3.11' of git://git.linaro.org/people/mturquette/linux: (55 commits) clk: tegra: fix ifdef for tegra_periph_reset_assert inline clk: tegra: provide tegra_periph_reset_assert alternative clk: exynos4: Fix clock aliases for cpufreq related clocks clk: samsung: Add MUX_FA macro to pass flag and alias clk: add support for Rockchip gate clocks clk: vexpress: Make the clock drivers directly available for arm64 clk: vexpress: Use full node name to identify individual clocks clk: tegra: T114: add DFLL DVCO reset control clk: tegra: T114: add DFLL source clocks clk: tegra: T114: add FCPU clock shaper programming, needed by the DFLL clk: gate: add CLK_GATE_HIWORD_MASK clk: divider: add CLK_DIVIDER_HIWORD_MASK flag clk: mux: add CLK_MUX_HIWORD_MASK clk: Always notify whole subtree when reparenting MAINTAINERS: make drivers/clk entry match subdirs clk: honor CLK_GET_RATE_NOCACHE in clk_set_rate clk: use clk_get_rate() for debugfs clk: tegra: Use override bits when needed clk: tegra: override bits for Tegra30 PLLM clk: tegra: override bits for Tegra114 PLLM ...
2013-05-29clk: si5351: Set initial clkout rate when defined in platform data.Marek Belisko1-0/+10
clock-frequency property from platform data was read but never used. Apply defined rate when clock is registered.

2013-05-29clk: si5351: Fix clkout rate computation.Marek Belisko1-1/+1
Rate was incorrectly computed because we read from wrong divider register. Signed-off-by: Marek Belisko <marek.belisko@streamunlimited.com> Acked-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> Signed-off-by: Mike Turquette <mturquette@linaro.org> Cc: stable@kernel.org
2013-05-28clk: si5351: declare all device IDs for module loadingJean-Francois Moine1-1/+4
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.

2013-05-28clk: si5351: Allow user to define disabled state for every clock outputSebastian Hesselbarth1-3/+71
This patch adds platform data and DT bindings to allow to overwrite the stored disabled state for each clock output.

2013-04-12clk: add si5351 i2c common clock driverSebastian Hesselbarth1-0/+1510
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.
