2015-06-02clk: ti: move low-level access and init code under clock driverTero Kristo1-5/+0
With most of the clock code under clock driver already, the low-level register access code, and the init code for the same, is no longer needed outside the clock driver. Thus, these can be moved under clock driver also. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02ARM: OMAP2+: clock: remove legacy omap2_clk_readl/writel APIsTero Kristo1-3/+0
As most of the clock driver code has migrated, these are no longer used for anything. Thus remove these APIs completely. Signed-off-by: Tero Kristo <t-kristo@ti.com>

2015-06-02clk: ti: clkdm: move clkdm gate clock support code to clock driverTero Kristo1-3/+0
With the legacy clock data gone, this is no longer needed under platform, so move it under the clock driver itself. Remove the exported clock driver APIs as well, as these are not needed outside clock driver anymore. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02ARM: OMAP2+: clock: remove clkdm_control static boolean from codeTero Kristo1-2/+0
clkdm_control is used to determine, whether clocks should trigger a clockdomain transition when they are enabled/disabled. Keep this functionality intact, but replace this with a clk_features flag which can be initialized during boot if needed. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02clk: ti: dpll: move omap3 DPLL functionality to clock driverTero Kristo1-4/+0
With the legacy clock support gone, OMAP3 generic DPLL code can now be moved over to the clock driver also. A few un-unused clkoutx2 functions are also removed at the same time. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02ARM: OMAP2+: clock: remove support for legacy mpurate command line paramTero Kristo1-1/+0
The legacy support is wrong and dangerous, as it doesn't take any OPPs into account and does not scale voltages. Switching mpurate should be handled through cpufreq. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02clk: ti: autoidle: move generic autoidle handling code to clock driverTero Kristo1-3/+0
This is no longer needed in platform directory, as the legacy clock data is gone, so move it under TI clock driver. Some static functions are renamed also. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02ARM: OMAP2+: clock: remove clock_common_data.c fileTero Kristo1-14/+0
This only contains clksel tables that were used with the legacy clock data. Now that legacy clock data is completely gone, this file can be removed also. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02ARM: OMAP2+: clk: remove obsolete clksel support codeTero Kristo1-12/+0
The clksel clock type is no longer used for anything, it is rather replaced with common clock divider code. Thus, remove the dead code from kernel. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02clk: ti: move interface clock implementation under drivers/clkTero Kristo1-11/+0
With the legacy clock support gone, the OMAP interface clock implementation can be moved under the clock driver. Some temporary header file tweaks are also needed to make this change work properly. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02clk: ti: move OMAP4+ DPLL implementation under drivers/clkTero Kristo1-4/+0

2015-06-02ARM: OMAP2+: clock: export driver API to setup/get clock featuresTero Kristo1-18/+0
As most of the clock driver support code is going to be moved under drivers/clk/ti, an API for setting / getting the SoC specific clock features is needed. This patch provides this API and changes the existing code to use it. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-31ARM: OMAP2+: clock: add low-level support for regmapTero Kristo1-1/+3
Some of the TI clock providers will be converted to use syscon, thus low-level regmap support is needed for the clock drivers also. This patch adds this support, which can be enabled for individual drivers in later patches. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-27ARM: OMAP2+: clock: move clock provider infrastructure to clock driverTero Kristo1-2/+4
Splits the clock provider init out of the PRM driver and moves it to clock driver. This is needed so that once the PRCM drivers are separated, they can logically just access the clock driver not needing to go through common PRM code. This would be wrong in the case of control module for example. Signed-off-by: Tero Kristo <t-kristo@ti.com>

git://git.linaro.org/people/mike.turquette/linux Pull clock framework updates from Mike Turquette: "The clock framework changes contain the usual driver additions, enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based devices. Additionally the framework core underwent a bit of surgery with two major changes: - The boundary between the clock core and clock providers (e.g clock drivers) is now more well defined with dedicated provider helper functions. struct clk no longer maps 1:1 with the hardware clock but is a true per-user cookie which helps us tracker users of hardware clocks and debug bad behavior. - The addition of rate constraints for clocks. Rate ranges are now supported which are analogous to the voltage ranges in the regulator framework. Unfortunately these changes to the core created some breakeage.

2015-02-03arm: omap2+ remove dead clock codeMichael Turquette1-5/+0
Remove omap_clocks_register and dummy_ck. The former is not used anymore now that the statically defined clk stuctures are replaced with proper descriptors and registered with the framework. The dummy clock in arch/arm/mach-omap2 is made redundant by the OMAP3+ clock data that migrated to drivers/clk. An additional benefit to this clean-up is removing the references to clk-private.h which will be removed.

2015-02-03clk: Make clk API return per-user struct clk instancesTomeu Vizoso1-2/+9
Moves clock state to struct clk_core, but takes care to change as little API as possible. struct clk_hw still has a pointer to a struct clk, which is the implementation's per-user clk instance, for backwards compatibility. The struct clk that clk_get_parent() returns isn't owned by the caller, but by the clock implementation, so the former shouldn't call clk_put() on it. Because some boards in mach-omap2 still register clocks statically, their clock registration had to be updated to take into account that the clock information is stored in struct clk_core now.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device-tree changes from Olof Johansson: "Unlike the board branch, this keeps having large sets of changes for every release, but that's quite expected and is so far working well. Most of this is plumbing for various device bindings and new platforms, but there's also a bit of cleanup and code removal for things that are moved from platform code to DT contents (some OMAP clock code in particular). There's also a pinctrl driver for tegra here (appropriately acked), that's introduced this way to make it more bisectable. I'm happy to say that there were no conflicts at all with this branch this release, which means that changes are flowing through our tree as expected instead of merged through driver maintainers (or at least not done with conflicts). There are several new boards added, and a couple of SoCs. In no particular order: - Rockchip RK3288 SoC support, including DTS for a dev board that they have seeded with some community developers. - Better support for Hardkernel Exynos4-based ODROID boards. - CCF conversions (and dtsi contents) for several Renesas platforms. - Gumstix Pepper (TI AM335x) board support - TI eval board support for AM437x - Allwinner A23 SoC, very similar to existing ones which mostly has resulted in DT changes for support.

2012-12-15ARM: OMAP4: Enhance support for DPLLs with 4X multiplierJon Hunter1-0/+10
On OMAP4 devices, the ABE DPLL has an internal 4X multiplier that can be enabled or disabled in addition to the standard configurable multiplier (M) for OMAP DPLLs. When configuring the ABE DPLL the 4X multiplier is accounted for by checking to see whether it is enabled or not. However, when calculating a new rate we only check to see if the rate can be achieved with the current setting for the 4X multiplier. Enhance the round_rate() function for such DPLLs to see if the rate can be achieved with the 4X multiplier if it cannot be achieved without the 4X multiplier. This change is necessary, because when using the 32kHz clock as the source clock for the ABE DPLL, the default DPLL frequency for the ABE DPLL cannot be achieved without enabling the 4X multiplier. When using the 32kHz clock as the source clock for the ABE DPLL and attempting to lock the DPLL to 98.304MHz (default frequency), it was found that the DPLL would fail to lock if the low-power mode for the DPLL was not enabled. From reviewing boot-loader settings that configure the ABE DPLL it was found that the low-power mode is enabled when using the 32kHz clock source, however, the documentation for OMAP does not state that this is a requirement. Therefore, introduce a new function for OMAP4 devices to see if low-power mode can be enabled when calculating a new rate to ensure the DPLL will lock. New variables for the last calculated 4X multiplier and low-power setting have been added to the dpll data structure as well as variables defining the bit mask for enabling these features via the DPLL's control_reg. It is possible that we could eliminate these bit masks from the dpll data structure as these bit masks are not unique to OMAP4, if it is preferred. The function omap3_noncore_program_dpll() has been updated to avoid passing the calculated values for the multiplier (M) and divider (N) as these are stored in the clk structure.
