The ARM IM-PD1 add-on module has a few clock of its own, let's move also these down to the drivers/clk/versatile driver dir and get rid of any remaining oldschool Integrator clocks. Signed-off-by:

It turns out that all platforms using the ICST VCO are really just touching two registers, and in the same way as well: one register with the VCO configuration as such, and one lock register that makes it possible to write to the VCO. Factor this register read/write into the ICST driver so we can reuse it in the IM-PD1 driver. Signed-off-by:

The GPLv2 headers were missing and the subsystem maintainer likes them so put them in. I am the copyright holder, so explicitly licensing these under the GPLv2. Reported-by:

In case of error, the function clk_register() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). dpatch engine is used to auto generate this patch. (https://github.com/weiyj/dpatch) Signed-off-by:

Using the armss clk to update the frequency makes the driver no more directly dependant on the prmcu API. Signed-off-by:
-
Ulf Hansson authored
The new armss clk is a prcmu_scalable_rate clk which represents the ARMSS clk. This then makes it possible to convert the smp_twd clk to a fixed factor clock type, using a fixed divider of 2 and with the armss clk as parent. Signed-off-by:

The prcmu_scalable_rate clock can change rate but is not gateable. Signed-off-by:
-
Ulf Hansson authored
ARMSS clk directly maps it's frequency towards the cpufreq table. To be able to update the ARMSS clk rate, a new set_rate function for the ARMSS clk is added, which also will trigger a corresponding ARM OPP request. Additionally an ARMSS clk round_rate function is added to fetch valid cpufreq frequencies. Signed-off-by:

By fetching the table as platform data we do not need the internally hardcoded cpufreq table anymore. Moreover the corresponding arm_opp idx2opp table, used for mapping frequency to correct opp bits is also removed. This due to that the opp bits is put directly in the index field of the cpufreq table. Signed-off-by:

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.

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. Signed-off-by:

Some of the helper functions return negative error codes if passed a NULL clock. This can lead to confusing behavior when the expected return value is unsigned. Fix up these accessors so that they return unsigned values (or bool in the case of is_enabled). This way we can't interpret NULL clocks as having valid and interesting values. Signed-off-by:

Pull ktest confusion fix from Steven Rostedt: "With the v3.7-rc2 kernel, the network cards on my target boxes were not being brought up. I found that the modules for the network was not being installed. This was due to the config CONFIG_MODULES_USE_ELF_RELA that came before CONFIG_MODULES, and confused ktest in thinking that CONFIG_MODULES=y was not found. Ktest needs to test all configs and not just stop if something starts with CONFIG_MODULES." * tag 'ktest-v3.7-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest: ktest: Fix ktest confusion with CONFIG_MODULES_USE_ELF_RELA
