2023-10-13clk: ti: Fix missing omap5 mcbsp functional clock and aliasesTony Lindgren1-0/+4
We are using a wrong mcbsp functional clock. The interconnect target module driver provided clock for mcbsp is not same as the mcbsp functional clock known as the gfclk main_clk. The mcbsp functional clocks for mcbsp should have been added before we dropped the legacy platform data. Additionally we are also missing the clock aliases for the clocks used by the audio driver if reparenting is needed. This causes audio driver errors like "CLKS: could not clk_get() prcm_fck" for mcbsp as reported by Andreas. The mcbsp clock aliases too should have been added before we dropped the legacy platform data. Let's add the clocks and aliases with a single patch to fix the issue similar to omap4. On omap5, there is no mcbsp4 instance on the l4_per interconnect. Fixes: b1da0fa21bd1 ("ARM: OMAP2+: Drop legacy platform data for omap5 mcbsp") Cc: H.

2022-06-16clk: ti: Stop using legacy clkctrl names for omap4 and 5Tony Lindgren1-80/+80
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.

The gpmc clock is needed to update omap5 to boot with genpd with the related devicetree patches. The ocmc clock is currently not used but let's add it so we have all the clocks for the l3main2 defined.

2020-12-17clk: ti: omap5: Fix reboot DPLL lock failure when using ABE TIMERsDavid Shah1-1/+11
Having the ABE DPLL ref and bypass muxes set to different inputs was causing the DPLL not to lock when TIMER8 was used, as it is in the Pyra for the backlight. This patch fixes this by setting abe_dpll_bypass_clk_mux to sys_32k_ck in omap5xxx_dt_clk_init. A similar patch may also be needed for OMAP44xx which has similar code in omap4xxx_dt_clk_init, but I have not added this as I have no hardware to test on.

2020-01-23ARM: dts: Add missing omap5 secure clocksTony Lindgren1-0/+13
The secure clocks on omap5 are similar to what we already have for dra7 with dra7_l4sec_clkctrl_regs and documented in the omap5432 TRM in "Table 3-1044. CORE_CM_CORE Registers Mapping Summary". The secure clocks are part of the l4per clock manager. As the l4per clock manager has now two clock domains as children, let's also update the l4per clockdomain node name to follow the "clock" node naming with a domain specific compatible property. Compared to omap4, omap5 has more clocks working in hardare autogating mode.

2019-10-31clk: ti: omap5: Drop idlest polling from IPU & DSP clkctrl clocksSuman Anna1-2/+2
The IPU and DSP remote processor cores and their corresponding MMUs on OMAP5 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.

2016-04-16clk: ti: dra7: fix kernel boot with arg 'clocksource=gp_timer'Grygorii Strashko1-0/+1
The OMAP Platform code provides possibility to select GP Timer as default clocksource instead of counter_32K by using bootcmd parameter 'clocksource', but the system will crash during early boot when this option is used on dra7 or omap5 platforms, because it will hit BUG() statement: omap2_gptimer_clocksource_init ->BUG_ON(res); This happens because clk_dev alias "sys_clkin_ck" is not registered. Hence, fix it by adding missing "sys_clkin_ck" clk_dev aliases definitions for omap5 and dra7.

2015-03-24clk: ti: OMAP5: Correct the DT clock aliases for timersSuman Anna1-11/+11
The DT clock aliases for Timers use the legacy (non-DT) device names and a source clock named sys_ck. OMAP5 is DT-boot only, so correct the DT clock aliases to use the DT device names instead. Also, the source clock name is corrected from 'sys_ck' to 'timer_sys_ck', the name used by the OMAP dmtimer driver.

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.
