      ARM: samsung: make SAMSUNG_DMADEV optional · 27873b05
      由 Arnd Bergmann 提交于 
      The only remaining driver using the samsung dmadev code is the broken
samsung-ac97 sound driver. However, as found by Russell's autobuilder,
the elaborate dependency chains around it cause problems with
circular dependencies.

This is an attempt to simplify those dependencies by making the
SAMSUNG_DMADEV option user-selectable. I also try to keep the
default settings for all related options unchanged, so we don't
introduce any regressions against earlier testing on linux-next.

In particular, all s3c64xx and s5p* platforms keep selecting the
pl330 and pl08x drivers they require, but the select statement
is now moved towards the main platform option, and it remains
optional by unselecting CONFIG_DMADEVICES.

      ARM: samsung: allow serial driver to be disabled · 0443a653
      由 Arnd Bergmann 提交于 
      If CONFIG_SERIAL_SAMSUNG is disabled, we run into build errors
with some samsung platforms. This adds a couple of #ifdef
statements to hopefully deal with this more gracefully.

      ARM: s5p64x0: fix building with only one soc type · 4f579c03
      由 Arnd Bergmann 提交于 
      The s5p64x0 platform supports two distinct SoCs, s5p6440 and s5p6450,
and in the normal configuration, both are enabled. However if we build
a kernel that only enables one of the two, the #ifdef logic in common.c
breaks down, as some of the functions declared in the header are defined
to NULL using the preprocessor but then defined anyway.

This patch cleans up the mess and ensures that each function has either
exactly one C declaration and one matching C definition, or we have
a NULL defined function pointer but no C definition.

      ARM: exynos: move debug-macro.S to include/debug/ · a2e40710
      由 Arnd Bergmann 提交于 
      The move is necessary to support early debug output on exynos
with multiplatform configurations. This implies also moving the
plat/debug-macro.S file, but we are leaving the remaining users of that
file in place, to avoid adding large numbers of extra configuration
options to Kconfig.debug

      ARM: SAMSUNG: Gracefully exit on suspend failure · d3fcacf5
      由 Abhilash Kesavan 提交于 
      As per the Exynos5250 User Manual:
When there are pending interrupt events, WFI/WFE instruction are
ignored. To cancel the power-down sequence follow these steps:
1) Disable system power-down using CENTRAL_SEQ_CONFIGURATION register
2) Clear WAKEUP_STAT register
3) Enable interrupt service routine for CPU

Code for early wakeup for exynos already exists. Remove the panic
on suspend failure, clear the wakeup state register and return 1
from cpu_suspend to indicate a failed suspend (to a user daemon).

Older Samsung SoCs have similar panics and I have removed them all.
Haven't touched the S3C2410 sleep code.

      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.)
