2022-06-16clk: ti: Stop using legacy clkctrl names for omap4 and 5Tony Lindgren1-105/+105
With the addition of clock-output-names, we can now unify the internal clock naming for omap4 and 5 to follow the other TI SoCs. We are still using legacy clkctrl names for omap4 and 5 based on the clock manager name which is wrong. Instead, we want to use the clkctrl clock based naming. We must now also drop the legacy TI_CLK_CLKCTRL_COMPAT quirk for the clkctrl clock. This change will allow further devicetree warning cleanup as already done for am3/4 and dra7.

2020-11-19clk: ti: omap4: Drop idlest polling from IVA clkctrl clocksTony Lindgren1-1/+1
Similar to what we've done for IPU and DSP let's ignore the status bit for the IVA clkctrl register. The clkctrl status won't change unless the related rstctrl is deasserted, and the rstctrl status won't change unless the clkctrl is enabled.

2020-05-14clk: ti: omap4: Add proper parent clocks for l4-secure clocksTero Kristo1-7/+7
L4 secure clocks do not have their parents set currently, which ends them up to the orphan clock list. Fix this by adding either l3 or l4 clock as their parent.

2020-01-23ARM: dts: Add missing omap4 secure clocksTony Lindgren1-0/+13
The secure clocks on omap4 are similar to what we already have for dra7 in dra7_l4sec_clkctrl_regs and documented in the omap4460 TRM "Table 3-1346 L4PER_CM2 Registers Mapping Summary". The secure clocks are part of the l4_per clock manager. As the l4_per clock manager has now two clock domains as children, let's also update the l4_per clockdomain node name to follow the "clock" node naming with a domain specific compatible property.

2019-10-31clk: ti: omap4: Drop idlest polling from IPU & DSP clkctrl clocksSuman Anna1-2/+2
The IPU and DSP remote processor cores and their corresponding MMUs on OMAP4 SoCs have hardreset lines associated with them and are controlled by a PRCM reset line each. Any clkctrl enable/disable operations cannot be checked for module enabled/disabled status independent of the reset operation, and this causes some unwanted timeouts in the kernel and unbalanced states for these clocks. These details should be handled by the driver integration code itself. Add the CLKF_NO_IDLEST flag to both the IPU and DSP clkctrl clocks so that these module status checks are skipped.

2017-12-01clk: ti: omap4: clkctrl data fixes for opt-clocksTero Kristo1-40/+115
Re-route all opt-clocks to use the new clkctrl clocks also, instead of depending on the old dt clocks. Also, add aliases for certain clkctrl clocks that hwmod core depends upon. The alias list can be stripped down once hwmod database no longer needs these. Signed-off-by: Tero Kristo <t-kristo@ti.com>

Most of the clock aliases are no longer needed, only leave the timer_32k_ck one in place which is required by OMAP timer code. Signed-off-by: Tero Kristo <t-kristo@ti.com>

The DT clock aliases for timers using the legacy OMAP timer device names have been cleaned up. These device names reflect the names used in legacy boot, and are no longer applicable as OMAP4 is DT boot only now. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-01-27clk: ti: Drop use of clk-private.hStephen Boyd1-1/+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.

2014-03-14CLK: TI: OMAP4/5/DRA7: Remove gpmc_fck from dummy clocksFlorian Vaussard1-1/+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.
