      ARM: msm: Fix uncompess.h tx underrun check · 73a8c28f
      由 Stephen Boyd 提交于 
      Bit 3 of the SR register is set if there is a tx underrun. If
this bit isn't set, we should loop on the tx ready bit until we
can transmit again. Otherwise we should skip the loop and
transmit immediately. The code is doing the opposite though,
checking for an underrun and then looping on the tx ready bit
causing us to never loop on the tx read bit when the tx buffer
may not be ready.

This doesn't seem to affect my 8960 device too often, but in some
cases I see a lost character or two from the decompressor prints.
This also matches what we do in the assembly in debug-macro.S.

      ARM: msm: Wait for timer clear to complete · e25e3d1f
      由 Stephen Boyd 提交于 
      Without looping on the status bit, there is no way to guarantee
that a clear of the timer has actually completed. This can cause
us to enable the timer before the count has cleared and miss a
timer interrupt. To simplify this patch, remove the timer
register setup done during timer init, since it's duplicate work
that is eventually done in the set_next_event() callback.

      ARM: msm: Rework timer binding to be more general · eebdb0c1
      由 Stephen Boyd 提交于 
      The msm timer binding I wrote is bad. First off, the clock
frequency in the binding for the dgt is wrong. Software divides
down the input rate by 4 to achieve the rate listed in the
binding. We also treat each individual timer as a separate
hardware component, when in reality there is one timer block
(that may be duplicated per cpu) with multiple timers within it.
Depending on the version of the hardware there can be one or two
general purpose timers, status and divider control registers, and
an entirely different register layout.

In the next patch we'll need to know about the different register
layouts so that we can properly check the status register after
clearing the count. The current binding makes this complicated
because the general purpose timer's reg property doesn't indicate
where that status register is, and in fact it is beyond the size
of the reg property.

Clean all this up by just having one node for the timer hardware,
and describe all the interrupts and clock frequencies supported
while having one reg property that covers the entire timer
register region. We'll use the compatible field in the future to
determine different register layouts and if we should read the
status registers, etc.

      ARM: msm: Stop counting before reprogramming clockevent · 4080d2d1
      由 Stephen Boyd 提交于 
      If the clockevent is forcibly reprogrammed to have a different
match value we mistakenly assume the timer is not ticking and
program a new match value while the timer is running. Although we
clear the timer before programming a new match, it's better to
stop the timer before clearing it so that we're sure the proper
amount of ticks are counted. Failure to do so can lead to missed
ticks and system hangs.

      ARM: msm: proc_comm_boot_wait should not be __init · 389d2111
      由 Arnd Bergmann 提交于 
      msm_smd_probe is a driver probe function and may get
called after the __init time, so it must not call
any __init function, as the link-time warning reports.
Take away the __init annotation on proc_comm_boot_wait
to fix this.

Without this patch, building msm_defconfig results in:

WARNING: vmlinux.o(.text+0xb048): Section mismatch in reference from the function msm_smd_probe() to the function .init.text:proc_comm_boot_wait()
The function msm_smd_probe() references
the function __init proc_comm_boot_wait().
This is often because msm_smd_probe lacks a __init
annotation or the annotation of proc_comm_boot_wait is wrong.

      ARM: drivers: remove __dev* attributes. · 351a102d
      由 Greg Kroah-Hartman 提交于 
      CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

      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.)

      Since the dtb targets have moved to arch/arm/boot/dts/Makefile, sweep

While I was at it, I also made the dtb generation more generic, i.e. if
the platform is enabled then all dtbs for that platform will be created.
