* ARM: S3C24XX: Fix mess with gpio {set,get}_pull callbacksVasily Khoruzhick2010-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently the {set,get}_pull callbacks of the s3c24xx_gpiocfg_default structure are initalized via s3c_gpio_{get,set}pull_1up. This results in a linker error when only CONFIG_CPU_S3C2442 is selected: arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f4): undefined reference to `s3c_gpio_getpull_1up' arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f8): undefined reference to `s3c_gpio_setpull_1up' The s3c2442 has pulldowns instead of pullups compared to the s3c2440. The method of controlling them is the same though. So this patch modifies the existing s3c_gpio_{get,set}pull_1up helper functions to take an additional parameter deciding whether the pin has a pullup or pulldown. The s3c_gpio_{get,set}pull_1{down,up} functions then wrap that functions passing either S3C_GPIO_PULL_UP or S3C_GPIO_PULL_DOWN. Furthermore this patch sets up the s3c24xx_gpiocfg_default.{get,set}_pull fields in the s3c244{0,2}_map_io function to the new pulldown helper functions.

* ARM: mini2440: Fix Kconfig to allow kernel to buildBen Dooks2010-12-03
| | | | | | | | | | | | | | | | The MACH_MINI2440 entry requires the backlight LED driver, but this subsystem has not been enabled and the select of LEDS_TRIGGER_BACKLIGHT alone is insufficient to enable the necessary bits of the LED driver. Add NEW_LEDS, LEDS_CLASS and LEDS_TRIGGER to the select to allow the kernel to link. This fixes the following error: drivers/built-in.o: In function `led_trigger_set': /home/ben/linux.git/drivers/leds/led-triggers.c:116: undefined reference to `led_brightness_set' Signed-off-by: Ben Dooks <ben-linux@fluff.org>

* | panic: keep blinking in spite of long spin timer modeTAMUKI Shoichi2010-08-11
|/ | | | | | | | | | | | | | | | | | | | | To keep panic_timeout accuracy when running under a hypervisor, the current implementation only spins on long time (1 second) calls to mdelay. That brings a good effect, but the problem is the keyboard LEDs don't blink at all on that situation. This patch changes to call to panic_blink_enter() between every mdelay and keeps blinking in spite of long spin timer mode. The time to call to mdelay is now 100ms. Even this change will keep panic_timeout accuracy enough when running under a hypervisor.
