OMAP4: hwmod data: Change DSS main_clk scheme

pm_runtime callbacks.

This patch changes the hwmod database for OMAP4 so that enabling the
hwmod via pm_runtime will also enable the DSS functional clock, allowing
us to use pm_runtime properly in DSS driver.

The DSS HWMOD side is not really correct, not before nor after this
patch, and getting DSS to retention will probably not work currently.
However, it is not supported in the mainline kernel anyway, so this
won't break anything.

So this patch allows us to write the pm_runtime adaptation for the DSS

disables the clocks of IVAHD, TESLA which is not desirable. Hence the
MPU OFF state is not usable on OMAP4430 devices.

OMAP4460 onwards, MPU OFF state will be descoped completely because
the DDR firewall falls in MPU power domain. When the MPU hit OFF state,
DDR won't be accessible for other initiators. The deepest state supported
is open switch retention (OSWR) just like CORE and PER PD on OMAP4430.

So in summary MPU power domain OFF state is not supported on OMAP4

10 years agoOMAP4: clock data: Keep GPMC clocks always enabled and hardware managed
Santosh Shilimkar [Sun, 10 Jul 2011 02:42:59 +0000 (20:42 -0600)]
OMAP4: clock data: Keep GPMC clocks always enabled and hardware managed

On OMAP4, CPU accesses on unmapped addresses are redirected to GPMC by
L3 interconnect. Because of CPU speculative nature, such accesses are
possible which can lead to indirect access to GPMC and if it's clock is
not running, it can result in hang/abort on the platform.

Above makes access to GPMC unpredictable during the execution, so it's
module mode needs to be kept under hardware control instead of software
control.
Since the auto gating is supported for GPMC, there isn't any power impact
because of this change.

The issue was un-covered with security middleware running along with HLOS.
In this case GPMC had a valid MMU descriptor on secure side where as HLOS
didn't map the GMPC because it isn't being used.

Previously, struct omap_hwmod_addr_space arrays were unterminated; and
users of these arrays used the ARRAY_SIZE() macro to determine the
length of the array.  However, ARRAY_SIZE() only works when the array
is in the same scope as the macro user.

So far this hasn't been a problem.  However, to reduce duplicated
data, a subsequent patch will move common data to a separate, shared
file.  When this is done, ARRAY_SIZE() will no longer be usable.

This patch removes ARRAY_SIZE() usage for struct omap_hwmod_addr_space
arrays and uses a null structure member as the array terminator
instead.

omap2+: Remove gptimer_wakeup for now

This removes the support for setting the wake-up timer for debugging.

Later on we can reserve gptimer1 for PM code only and have similar
functionality.

This patch makes timer-gp.c to use only a subset of dmtimer

Also note that now with the inline functions, timer_set_next_event
becomes more efficient in the lines of assembly code.

As with the init_irq calls, there's no need to do cpu_is_omap calls
during the timer init as we only care about the major omap generation.
This means that we can initialize the sys_timer with the .timer
entries alone.

Note that for now we just set stubs for the various sys_timer entries
that will get populated in a later patch. The following patches will
also remove the omap_dm_timer_init calls and change the init for the
rest of the hardware timers to happen with an arch_initcall.
