* Merge branch 'for-4.2/ti-clk-move' of https://github.com/t-kristo/linux-pm ↵Stephen Boyd2015-07-281-1/+2
|\ | | | | | | | | | | | | | | | | | | | | | | | | into clk-next From Tero Kristo: "This pull request contains the TI clock driver set to move the clock implementations under clock driver. Some small portions of the clock driver code still remain under mach-omap2 after this, it should be decided whether this code is now obsolete and should be deleted or should someone try to fix it." Slight merge conflicts with determine_rate prototype changes.
| * clk: ti: move some public definitions to private headerTero Kristo2015-06-021-1/+2
| | | | | | | | | | | | | | | | | | Several exported TI clock driver features are no longer needed outside the clock driver itself, thus move all of these to the driver private header file. Also, update some of the driver files to actually include this header. Signed-off-by: Tero Kristo <t-kristo@ti.com>
* | CLK: TI: always enable DESHDCP clockTomi Valkeinen2015-06-041-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DESHDCP clock is needed on DRA7 based SoCs to enable the DSS IP. That clock is an odd one, as it is not supposed to be any kind of core clock for DSS, and we don't even support HDCP, but the clock is still needed even for the HWMOD framework to be able to reset the DSS IP. As there's no support for multiple core clocks in the HWMOD framework, we don't have any obvious place to enable this clock when DSS IP is being enabled. Furthermore, the HDMI on OMAP5 DSS is the same as on DRA7, and OMAP5 does not have any such clock configuration bit. This suggests that on OMAP5 the DESHDCP clock is always enabled, and for DRA7 we have the possibility to gate it. So, as we don't have any clean way to enable and disable the clock based on the need, this patch enables the clock at boot time, making it work similarly to OMAP5.

* clk: ti: DRA7: Add timer_sys_ck aliases for Timers 13 through 16Suman Anna2015-03-241-0/+4
| | | | | | | | | | The OMAP DMTimer API, omap_dm_timer_set_source(), uses the clock name timer_sys_ck for setting a timer's clock source for the source index OMAP_TIMER_SRC_SYS_CLK. There is currently no clock alias data for the Timers 13 through 16 for this clock name, so add the same. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Tero Kristo <t-kristo@ti.com>
* clk: ti: DRA7: Correct timer_sys_ck clock aliases for TimersSuman Anna2015-03-241-7/+7
| | | | | | | | | | | | | The OMAP DMTimer API, omap_dm_timer_set_source(), can set the parent of a timer node using 3 different values that use fixed parent names for the clocks. The parent name, timer_sys_ck, is used for setting the parent when used with the source index OMAP_TIMER_SRC_SYS_CLK. This should point to the TIMER_SYS_CLK and not the SYSCLKIN2, so correct the clock aliases appropriately. SYSCLKIN2 is not a mandatory clock input.

* clk: ti: Drop use of clk-private.hStephen Boyd2015-01-271-1/+1
| | | | | | | | | | | | | These modules don't need to include clk-private.h. Replace the include with clk.h because these modules are clock consumers and also include clk-provider.h in clk/ti.h because struct clk_hw_omap has a struct clk_hw embedded in it.

* CLK: TI: OMAP4/5/DRA7: Remove gpmc_fck from dummy clocksFlorian Vaussard2014-03-131-1/+0
| | | | | | | | | | | | | | | When arch/arm/mach-omap2/gpmc.c calls clk_get(..., "fck"), it will get a dummy clock and try to use it. As the rate is configured to zero, this will result in several divisions by zero, and misconfigured timings, with devices on the bus being lost in the La La Land. It is better to remove gpmc_fck from the dummy clocks, so that gpmc.c can fail gracefully.
