This series is the second of six to bring the mainline kernel OMAP
clock code up-to-date with the linux-omap tree.
Major changes in this series:
- Fix clockdomain, powerdomain code and data to match the hardware
- Add PRCM clockdomains
- Add DPLL clockdomains, powerdomains
- Mark all OMAP clocks with clockdomains
- Combine pwrdm, clkdm names and pointers into unions
Some patches have been "compressed" together, as requested by rmk -
original commit IDs are in the patch descriptions.
Compile-tested on OSK5912 (OMAP1), H4 and 2430SDP (OMAP2), and
BeagleBoard (OMAP3). Boot-tested on 2430SDP and BeagleBoard.
Applies on top of series A, posted earlier.

struct clk contains a struct clockdomain *clkdm and const char
*clkdm_name. The clkdm_name is only used at initialization to look up
the appropriate clkdm pointer. Combining these into a union saves
about 850 bytes on 3430SDP. This patch should not cause any change in
kernel function.
Boot-tested on 3430SDP ES2; compile-tested with n800_defconfig.
linux-omap source commit is 0e5194e1a84c219bebbb78f305b7a8eabc4a3656.

From: Paul Walmsley @ 2009-01-28 2:44 UTC (permalink / raw)
To: linux-arm-kernel, linux-kernel; +Cc: linux-omap, Paul Walmsley, Tony Lindgren
struct clockdomain contains a struct powerdomain *pwrdm and const char
*pwrdm_name. The pwrdm_name is only used at initialization to look up
the appropriate pwrdm pointer. Combining these into a union saves
about 100 bytes on 3430SDP. This patch should not cause any change in
kernel function.
Boot-tested on 3430SDP ES2.
linux-omap source commit is 718fc6cd4db902aa2242a736cc3feb8744a4c71a.

Add clockdomains for the CM and PRM. These replace "wkup_clkdm", a
placeholder clockdomain which does not exist on the hardware. Add a
clockdomain for virtual OPP clocks, "virt_opp_clkdm". Mark all clocks
in the clock tree with a valid clockdomain.

Addendum Version B TRM
This patch includes an earlier fix to sys_clkout2's clockdomain by
Tomi Valkeinen <tomi.valkeinen@nokia.com>.

To: linux-arm-kernel, linux-kernel; +Cc: linux-omap, Paul Walmsley, Tony Lindgren
Each DPLL exists in its own powerdomain (cf 34xx TRM figure 4-18) and
clockdomain; so, create powerdomain and clockdomain structures for them.
Mark each DPLL clock as belonging to their respective DPLL clockdomain.
cf. 34xx TRM Table 4-27 (among other references).

Add clockdomains for all remaining clocks without them, and warn in
clk_register() if any are missing a clockdomain. On OMAP2, call
omap2_init_clk_clkdm() immediately after clk_register(), just as OMAP3
does. Remove omap2_init_clk_clkdm() from all of the struct clk .init
function pointers, since the OMAP2/3 arch clock init code now calls it.
The following TI documents are used as reference:
OMAP2420 Multimedia Processor Silicon Revision 2.1.1, 2.2 TRM Version Q
OMAP2430 Multimedia Device Package-on-Package (POP) Silicon Revision 2.1 TRM
Version Q
OMAP34xx Multimedia Device Silicon Revision 3.0 Version I TRM
OMAP34xx Multimedia High Security (HS) Device Silicon Revision 3.0 Security
Addendum Version B TRM
The bug caused by the missing call to omap2_init_clk_clkdm() on OMAP2
was reported by Felipe Balbi <felipe.balbi@nokia.com>.

34xx TRM Delta G->H notes that the CORE powerdomain has a hardware
save-and-restore (SAR) control bit for the USBTLL module, similar to
the USBHOST powerdomain SAR bit. Split the existing core_34xx struct
powerdomain into two structs, one for ES1 and one for ES2, and add the
PWRDM_HAS_HDWR_SAR flag to the ES2 powerdomain.

Enabling clock in a disabled power domain causes the power domain to be
turned on. However, the power transition is not always finished when
clk_enable() returns and this randomly crashes the kernel when an
interrupt happens right after the clk_enable, and the kernel tries to
read the irq status register for that domain.
Why the irq status register is inaccessible, I don't know. Also it
doesn't seem to be related to the module being not powered up, but to
the transition itself.
The same could perhaps happen after clk_disable also, but I have not
witnessed that.
The problem affects at least dss, cam and sgx clocks.
This change waits for the transition to be finished before returning
from omap2_clkdm_clk_enable().

Using sdti doesn't keep emu_pwrdm on if hardware supervised pwrdm
transitions are used. This causes sdti stop to work when power
management is initialized and hardware supervised pwrdm control is
enabled. This patch disables hardware supervised pwrdm control for
emu_pwrdm. Now emu_pwrdm is switched off on boot by software when it
is not used.

TLLSAR is not functional till ES3.1 (and beyound). Is it possible to flag it this way?
If you try and use it your system will deadlock on 2nd OFF mode transition due to hardware bug.

N.B. - fixxing this required a separate change to the omap_chip flag
system, so I'll send the two necessary patches to the linux-omap mailing

This is unsafe - if the clock domain can not be found, you leave the
union pointing at the string, and there's no way for this to prevent
the clock from being registered.
The result is that:
> - if (clk->clkdm)
> - omap2_clkdm_clk_disable(clk->clkdm, clk);
> + if (clk->clkdm.ptr)
> + omap2_clkdm_clk_disable(clk->clkdm.ptr, clk);
and similar places will pass the pointer to the string, potentially
causing an oops, or worse, data corruption due to scribbing over
someone elses memory.
So I don't think this patch is acceptable as-is.

For the same reasons as B1, this would seem to be unsafe.

I don't really see the need to mark all these clocks as having a domain.
Yes, it makes sense to mark the actual DPLL clocks themselves with the
relevent DPLL domain. However, it makes no sense to mark the children
as well.
Why? When we enable a clock, we walk up the tree enabling the domains
first. So, even if we're enabling a child clock, we will walk the tree
up to the DPLL and enable the clock domain before we do anything at all.
Sure, if a clock has a multiplexer and that multiplexer is in a different
clock domain from its parent, it makes sense to. But otherwise it doesn't.

Agreed. Now that omap2_init_clk_clkdm() is called by the
OMAP arch-specific clk_register(), this should be pretty easy to
implement. Will send a patch that applies on top of F 06.

OMAP2/3 clockdomains: combine pwrdm, pwrdm_name into union in struct clockdomain
struct clockdomain contains a struct powerdomain *pwrdm and const char
*pwrdm_name. The pwrdm_name is only used at initialization to look up
the appropriate pwrdm pointer. Combining these into a union saves
about 100 bytes on 3430SDP. This patch should not cause any change in
kernel function.
Updated to gracefully handle autodeps that contain invalid powerdomains,
per Russell King's review comments.
Boot-tested on BeagleBoard ES2.1.
linux-omap source commit is 718fc6cd4db902aa2242a736cc3feb8744a4c71a.

OMAP2/3 clockdomains: combine pwrdm, pwrdm_name into union in struct clockdomain
struct clockdomain contains a struct powerdomain *pwrdm and const char
*pwrdm_name. The pwrdm_name is only used at initialization to look up
the appropriate pwrdm pointer. Combining these into a union saves
about 100 bytes on 3430SDP. This patch should not cause any change in
kernel function.
Updated to gracefully handle autodeps that contain invalid powerdomains,
per Russell King's review comments.
Boot-tested on BeagleBoard ES2.1.
linux-omap source commit is 718fc6cd4db902aa2242a736cc3feb8744a4c71a.

The following patch prevents a clock with a bad or missing clockdomain
from registering. It applies after F 06.

OMAP2/3 clock: prevent clock registration with bad or missing clockdomain
If clk_register() is called on a struct clk without a clockdomain
name, or a struct clk which contains an invalid clockdomain name, fail
the clock registration. This prevents later code from inadvertently
dereferencing the clockdomain name string as a struct clockdomain
pointer.
Problem reported by Russell King <linux@arm.linux.org.uk>.
Tested on BeagleBoard ES2.1.

The patches that obsolete patch B 06 have lasted a week on linux-omap@vger
without any comment, so am passing them along in subsequent E-mails.

It seems that the patches don't obsolete this patch, but instead
require this patch to be applied first.
We really really need to get out of this pattern of building fixes
on top of bad patches. If a patch is the wrong approach then it is
the wrong approach and should be dropped, or it should be merged with
the patches which fix stuff up to the new approach.
I'm going to combine B06 with patch 2 and hope things come out right.

The motivation was to make your life easier; otherwise several later
patches would need to be updated and re-posted.

How would you like me to handle patch rewrites when they affect later
patches in the series, as this one did? Shall I re-send updates of any
later affected patches?
