      ARM: at91: add Kconfig options for common clk support · c8a8c630
      由 Boris BREZILLON 提交于 
      This patch adds the following Kconfig options to prepare the transition to
common clk framework:

- AT91_USE_OLD_CLK: this option is selected by every SoC which does not
  support new at91 clks based on common clk framework (SoC which does not
  define the clock tree in its device tree).
  This options is also selected when the user choose non dt boards support
  (new at91 clks can only be registered from a device tree definition).

- COMMON_CLK_AT91: this option cannot be selected directly. Instead it is
  enabled if these 3 conditions are met:
   * at least one of the selected SoCs have a PMC (Power Management
     Controller) Unit
   * device tree support is enabled
   * the old at91 clk implementation is disabled (every selected SoC define
     its clks in its device tree and non dt boards support is disabled)

- OLD_CLK_AT91: this option cannot be selected directly. Instead it is
  enabled if these 2 conditions are met:
   * at least one of the selected SoCs have a PMC (Power Management
     Controller) Unit
   * at least one of the selected SoCs does not define its clks in its
     device tree or non dt-boards support is enabled

This patch selects AT91_USE_OLD_CLK in all currently supported SoCs. These
selects will be removed after clk definitions are properly added in each
soc's device tree.
It also selects AT91_USE_OLD_CLK in all non-dt boards support.

AT91_PMC_UNIT references are replaced by OLD_CLK_AT91, because PMC Unit is
enabled for both old and common clk implementations, and old clk
implementation should not be compiled if COMMON_CLK is enabled.

To avoid future link errors, a new stub is created for at91_dt_clock_init
function if OLD_CLK_AT91 is disabled.

A new check is added in dt init functions (setup.c) to prepare for SoCs
supporting new clk implementation. These SoCs won't setup the
register_clocks callback (clk registration is done using of_clk_init).

      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.)
