      ARM: shmobile: INTC External IRQ pin driver on r8a7779 · 8e56e6d5
      由 Magnus Damm 提交于 
      Update the r8a7779 IRQ code to make use of the
INTC External IRQ pin driver for external
interrupt pins IRQ0 -> IRQ3.

The r8a7779 SoC can like older SH SoCs configure
to use the IRQ0 -> IRQ3 signals as individual
interrupts or a combined IRL mode.

Without this patch the r8a7779 SoC code does
not fully support external IRQ pins in individual
IRQ mode. The r8a7779 PFC code does not yet have
gpio_to_irq() support so no need to update such
code.

At this point the DT reference implementations
are not covered. In the future such code shall
tie in the INTC External IRQ pin driver via
DT, so this kind of verbose code is not needed
for the long term DT case.

      ARM: shmobile: INTC External IRQ pin driver on sh73a0 · 341eb546
      由 Magnus Damm 提交于 
      Adjust the sh73a0 IRQ code to make use of the
INTC External IRQ pin driver for external
interrupt pins IRQ0 -> IRQ31.

This removes quite a bit of special-case code
in intc-sh73a0.c but the number of lines get
replaced with platform device information in
setup-sh73a0.c. The PFC code is also adjusted
to make gpio_to_irq() return the correct
interrupt number.

At this point the DT reference implementations
are not covered. In the future such code shall
tie in the INTC External IRQ pin driver via
DT, so this kind of verbose code is not needed
for the long term DT case.

      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: mach-shmobile: Initial AG5 and AG5EVM support · 6d9598e2
      由 Magnus Damm 提交于 
      This patch adds initial support for Renesas SH-Mobile AG5.

At this point the AG5 CPU support is limited to the ARM
core, SCIF serial and a CMT timer together with L2 cache
and the GIC. The AG5EVM board also supports Ethernet.

Future patches will add support for GPIO, INTCS, CPGA
and platform data / driver updates for devices such as
IIC, LCDC, FSI, KEYSC, CEU and SDHI among others.

The code in entry-macro.S will be cleaned up when the
ARM IRQ demux code improvements have been merged.

Depends on the AG5EVM mach-type recently registered but
not yet present in arch/arm/tools/mach-types.

As the AG5EVM board comes with 512MiB memory it is
recommended to turn on HIGHMEM.

Many thanks to Yoshii-san for initial bring up.
