      ARM: config: sort select statements alphanumerically · b1b3f49c
      由 Russell King 提交于 
      As suggested by Andrew Morton:

  This is a pet peeve of mine.  Any time there's a long list of items
  (header file inclusions, kconfig entries, array initalisers, etc) and
  someone wants to add a new item, they *always* go and stick it at the
  end of the list.

  Guys, don't do this.  Either put the new item into a randomly-chosen
  position or, probably better, alphanumerically sort the list.

lets sort all our select statements alphanumerically.  This commit was
created by the following perl:

while (<>) {
	while (/\\\s*$/) {
		$_ .= <>;
	}
	undef %selects if /^\s*config\s+/;
	if (/^\s+select\s+(\w+).*/) {
		if (defined($selects{$1})) {
			if ($selects{$1} eq $_) {
				print STDERR "Warning: removing duplicated $1 entry\n";
			} else {
				print STDERR "Error: $1 differently selected\n".
					"\tOld: $selects{$1}\n".
					"\tNew: $_\n";
				exit 1;
			}
		}
		$selects{$1} = $_;
		next;
	}
	if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
			  /^endif/ or /^endchoice/)) {
		foreach $k (sort (keys %selects)) {
			print "$selects{$k}";
		}
		undef %selects;
	}
	print;
}
if (%selects) {
	foreach $k (sort (keys %selects)) {
		print "$selects{$k}";
	}
}

It found two duplicates:

Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry

and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.

We have four testers reporting success of this change (Tony, Stephen,
Linus and Sekhar.)

      ARM: OMAP4460/4470: PMU: Enable PMU for OMAP4460/70 · 76a5d9bf
      由 Jon Hunter 提交于 
      OMAP4460 and OMAP4470 devices have dedicated PMU interrupts and so add these
interrupts to the MPU HWMOD so we can use these for PMU events on these
devices. The PMU interrupts need to be the first interrupts in the array of
interrupts as the ARM PMU driver assumes this.

By using these dedicated interrupts we only need to enable the MPU and DEBUG
sub-systems for PMU to work. This is different to OMAP4430 that did not have
dedicated interrupts and required other power domains in addition to the DEBUG
sub-system to be enabled so we could route the PMU events to the CTI interrupts.
Hence, OMAP4460 and OMAP4470 devices can use the same list of HWMODs to create
the PMU device that is using by OMAP3.

      ARM: OMAP2+: PMU: Add runtime PM support · 6a9bce27
      由 Jon Hunter 提交于 
      The original implementation of this patch was done by Ming Lei for PMU on OMAP4
[1]. Since then the PM runtime calls have been moved into the ARM PMU code and
this greatly simplifies the changes.

The another differnce since the original version, is that it is no longer
necessary to call pm_runtime_get/put during the PMU initialisation was we are no
longer accessing the hardware at this stage.

By adding runtime PM support, we can ensure that the appropriate power and clock
domains are kept on while PMU is being used.

      ARM: OMAP4430: PMU: prepare to create PMU device via HWMOD · efc7f49c
      由 Ming Lei 提交于 
      For OMAP4430 PMU events are routed to the CPU via the cross trigger interface
(CTI) because there are no dedicated interrupts. In order to route the PMU
events via the CTI IRQs, the following modules must be enabled:

        l3_instr, l3_main_3, debugss

Therefore, build the arm-pmu device via these three HWMODs.

However, the CTI support for this platform still needs some work.  Until
that's finished, temporarily disable the PMU on OMAP4430.

      ARM: OMAP2+: PMU: Convert OMAP2/3 devices to use HWMOD · ee75d95c
      由 Jon Hunter 提交于 
      Convert OMAP2/3 devices to use HWMOD for creating a PMU device. To support PMU
on OMAP2 devices we only need to use MPU sub-system and so we can simply use
the MPU HWMOD to create the PMU device. To support PMU on OMAP3 devices, we need
to use the MPU and DEBUG sub-systems and so use these HWMODs to create the PMU
device for OMAP3.

The MPU HWMOD for OMAP2/3 devices is currently missing the PMU interrupt and so
add the PMU interrupt to the MPU HWMOD for these devices.

This change also moves the PMU code out of the mach-omap2/devices.c files into
its own pmu.c file as suggested by Kevin Hilman to de-clutter devices.c.

      ARM: OMAP3: hwmod data: Add debugss HWMOD data · c7dad45f
      由 Jon Hunter 提交于 
      To enable PMU with runtime PM support on OMAP3 devices we need to be able to
dynamically enable and disable the debug sub-system at runtime. By adding HWMOD
data for the debug sub-system for OMAP3, we can build the PMU device using the
debug sub-system HWMOD and control this power domain using runtime PM.
