      ARM: pxa/spitz_pm: Fix hang when resuming from STR · 510fcb0d
      Marko Katic 提交于
      Devices that use spitz_pm.c will fail to resume
      from STR (Suspend To Ram) when the charger plug is inserted
      or removed when a device is in STR mode. The culprit is
      a misconfigured gpio line - GPIO18. GPIO18 should be configured as a
      regular GPIO input but it gets configured as an alternate function
      GPIO18_RDY. And then later in postsuspend() it gets configured as
      a regular GPIO18 input line.
      
      Fix this by removing the GPIO18_RDY configuration so that GPIO18
      only gets configured as a regular gpio input.

      ARM: pxa: hx4700: Fix backlight PWM device number · 8d6b00f5
      Paul Parsons 提交于
      Recent changes to PXA PWM support changed the PXA27X PWM device
      numbering scheme.
      
      The linux-3.5 PXA PWM driver followed the hardware numbering scheme for
      the 4 PWMs, while the linux-3.6-rc1 PXA PWM driver has adopted a linear
      numbering scheme:
      
      Address		Hardware	3.5 pwm_id	3.6-rc1 pwm_id
      0x40b00000	PWM0		0		0
      0x40b00010	PWM2		2		1
      0x40c00000	PWM1		1		2
      0x40c00010	PWM3		3		3
      
      The hx4700 backlight uses PWM1 at 0x40c00000. Consequently the pwm_id
      must be changed from 1 to 2.
      
      This patch fixes the backlight PWM device number and at the same time
      moves from the legacy PWM API (pwm_id) to the new PWM API (pwm_lookup).

      ARM: config: sort select statements alphanumerically · b1b3f49c
      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: pxa: work around duplicate definition of GPIO24_SSP1_SFRM · e0347c52
      Arnd Bergmann 提交于
      The symbol "GPIO24_SSP1_SFRM" is defined in both mfp-pxa27x.h and
      mfp-pxa25x.h. Since the macro is not actually used in the cm-x2xx.c
      file, but it includes both headers, a safe workaround should be
      to just undefine it from the .c file. This is a bit hacky and
      the headers should be fixed to not both define it, but for now
      it gets us around an annoying warning.
      
      Without this patch, building cm_x2xx_defconfig results in:

      workqueue: deprecate flush[_delayed]_work_sync() · 43829731

      flush[_delayed]_work_sync() are now spurious.  Mark them deprecated
      and convert all users to flush[_delayed]_work().
      
      If you're cc'd and wondering what's going on: Now all workqueues are
      non-reentrant and the regular flushes guarantee that the work item is
      not pending or running on any CPU on return, so there's no reason to
      use the sync flushes at all and they're going away.
      
      This patch doesn't make any functional difference.

      Input: eeti_ts: pass gpio value instead of IRQ · 4eef6cbf
      Arnd Bergmann 提交于
      The EETI touchscreen asserts its IRQ line as soon as it has data in its
      internal buffers. The line is automatically deasserted once all data has
      been read via I2C. Hence, the driver has to monitor the GPIO line and
      cannot simply rely on the interrupt handler reception.
      
      In the current implementation of the driver, irq_to_gpio() is used to
      determine the GPIO number from the i2c_client's IRQ value.
      
      As irq_to_gpio() is not available on all platforms, this patch changes
      this and makes the driver ignore the passed in IRQ. Instead, a GPIO is
      added to the platform_data struct and gpio_to_irq is used to derive the
      IRQ from that GPIO. If this fails, bail out. The driver is only able to
      work in environments where the touchscreen GPIO can be mapped to an
      IRQ.
