* clk-fixes: Partially revert "clk: mvebu: Convert to clk_hw based provider APIs"
2015-10-14Partially revert "clk: mvebu: Convert to clk_hw based provider APIs"Stephen Boyd1-1/+3
This partially reverts commit eca61c9ff2588e1df373e61078e1874976315839. Thomas reports that it causes regressions on Armada XP devices. This is because of_clk_get_parent_name() relies on the property 'clock-output-names' to resolve the name of a clock's parent, without trying to get the clock from the framework and call __clk_get_name(). Given that Armada XP devices don't have the 'clock-output-names' property, of_clk_get_parent_name() returns the name of the node which doesn't match the actual parent clock's name at all, causing CPU clocks to never link up with their parents.

We're removing struct clk from the clk provider API, so switch this code to using the clk_hw based provider APIs.

This commit adds a new clock driver for the Marvell Armada 39x family of processors.

2015-03-04clk: mvebu: extend common code to allow an optional refclkThomas Petazzoni2-0/+18
The Armada 39x, contrary to its predecessor, has a configurable reference clock frequency, of either 25 Mhz, or 40 Mhz. For the previous SoCs, it was fixed to 25 Mhz and described directly as such in the Device Tree. For Armada 39x, we need to read certain registers to know whether the frequency is 25 or 40 Mhz. Therefore, this commit extends the common mvebu clock code to allow the SoC-specific code to say it wants to register a reference clock, by giving a non-NULL ->get_refclk_freq() function pointer in its coreclk_soc_desc structure.

2014-11-30clk: mvebu: add suspend/resume for gatable clocksThomas Petazzoni1-2/+30
This commit adds suspend/resume support for the gatable clock driver used on Marvell EBU platforms. When getting out of suspend, the Marvell EBU platforms go through the bootloader, which re-enables all gatable clocks. However, upon resume, the clock framework will not disable again all gatable clocks that are not used. Therefore, if the clock driver does not save/restore the state of the gatable clocks, all gatable clocks that are not claimed by any device driver will remain enabled after a resume. This is why this driver saves and restores the state of those clocks. Since clocks aren't real devices, we don't have the normal ->suspend() and ->resume() of the device model, and have to use the ->suspend() and ->resume() hooks of the syscore_ops mechanism. This mechanism has the unfortunate idea of not providing a way of passing private data, which requires us to change the driver to make the assumption that there is only once instance of the gatable clock control structure.

clock changes for mvebu for v3.18 - correct timer drift caused by SSCG deviation - fix typo in comment
2014-09-16clk: mvebu: fix sscg node lookupThomas Petazzoni2-5/+5
Commit 15917b16022427c53755abff4dc7051f3076dd7a ("clk: mvebu: Fix clk frequency value if SSCG is enabled") introduced some logic in the common mvebu clock code to adjust the clock frequency according to the configuration of the SSCG. In order to do this, it looks up for a DT node called "sscg" and maps it before accessing the SSCG configuration register. However, the lookup is currently done using: sscg_np = of_find_node_by_name(np, "sscg"); where "np" is a pointer to the DT node of the clock for which we are calculating the adjusted frequency. This means that if the "sscg" node is *after* the clock node in the Device Tree, it works fine (and that's the case for Armada 370). However, if it turns out that the "sscg" node is *before* the clock node in the Device Tree, it won't work because the sscg node will not be found. What we really want here is a search of the entire Device Tree, not only starting from the clock node, so instead of passing "np" as first argument of of_find_node_by_name(), we simply need to pass NULL. Passing a non-NULL argument is typically used in a loop, so that the search for the next matching node starts right after the node that was matched. This makes the "np" argument to the kirkwood_fix_sscg_deviation() function unnecessary, which leads to further cleanups.

2014-09-09clk: mvebu: Fix clk frequency value if SSCG is enabledGregory CLEMENT2-0/+89
When the SSCG (Spread Spectrum Clock Generator) is enabled, it shifts the frequency of the clock. The percentage is no more than 1% but when the clock is used for a timer it leads to a clock drift. This patch allows to correct the affected clock when the SSCG is enabled. The check is done in an new optional function related to each SoC: is_sscg_enabled(). The fix is done with the other new optional function related to each SoC: fix_sscg_deviation. If one these functions are not present then no correction is done on the clock frequency.

2014-09-02cpufreq: kirkwood: use the powersave multiplexerMike Turquette1-2/+13
The powersave clock acts like a multiplexer for the cpu, selecting either the clock signal derived from the cpu pll or from the ddr clock. This patch changes powersave from a gate clock to a mux clock to better reflect this behavior. This is a cleaner approach whereby the frequency of the cpu always matches the rate of powersave_clk. The cpufreq driver for the kirkwood platform no longer must parse this behavior out of various calls to clk_enable and clk_disable, but can instead simply select the parent cpu it wants when changing rate. Likewise when requesting the cpu rate we need only query powersave_clk's rate through the usual call to clk_get_rate. The new clock data and corresponding changes to the cpufreq driver are combined into this single commit to avoid a git bisect issue where this cpufreq driver fails to work properly between the commit that updates the kirkwood clock driver and the commit that changes how the cpufreq driver uses that clock.

2014-09-01clk: mvebu: powersave clock is a multiplexerMike Turquette1-0/+87
Kirkwood is unique among the mvebu SoCs for having a clock multiplexer that feeds into the cpu. This multiplexer can select either the cpu pll or the ddr clock as its input signal, allowing for a choice between performance and power savings. This patch introduces the code needed to register the clock multiplexer on Kirkwood SoCs but does not include the clock data to actually register the clock. That will be done in a follow-up patch which is necessary to prevent breaking git bisect.

2014-07-16clk: mvebu: extend clk-cpu for dynamic frequency scalingThomas Petazzoni1-5/+75
This commit extends the existing clk-cpu driver used on Marvell Armada XP platforms to support the dynamic frequency scaling of the CPU clock. Non-dynamic frequency change was already supported (and used before secondary CPUs are started), but the dynamic frequency change requires a completely different procedure. In order to achieve this, the clk_cpu_set_rate() function is reworked to handle two separate cases: - The case where the clock is enabled, which is the new dynamic frequency change code, implemented in clk_cpu_on_set_rate(). This part will be used for cpufreq activities. - The case where the clock is disabled, which is the existing frequency change code, moved in clk_cpu_off_set_rate(). This part is already used to set the clock frequency of the secondary CPUs before starting them. In order to implement the dynamic frequency change function, we need to access the PMU DFS registers, which are outside the currently mapped "Clock Complex" registers, so a new area of registers is now mapped. This affects the Device Tree binding, but we are careful to do it in a backward-compatible way (by allowing the second pair of registers to be non-existent, and in this case, ensuring clk_cpu_on_set_rate() returns an error). Note that technically speaking, the clk_cpu_on_set_rate() does not do the entire procedure needed to change the frequency dynamically, as it involves touching a number of PMSU registers. This is done through a clock notifier registered by the PMSU driver in followup commits.

Switch from function-centric to soc-centric clock drivers now makes a bunch of files obsolete. This deletes all files and Kconfig options that are not required anymore.

2013-05-29clk: mvebu: add Armada XP SoC-centric clock initSebastian Hesselbarth3-0/+216
This is moving core clock and clock gating init for Armada XP to its own file and adds a Kconfig option. Also init functions are added and declared so they get called on of_clk_init.

2013-05-29clk: mvebu: add common clock functions for core clk and clk gatingSebastian Hesselbarth4-0/+215
Based on the current common functions for core clocks and clock gating control, new common functions are joined in a single file. Given the opportunity, names of functions and structs are unified, and also a Kconfig entry is added.
