* omapfb: add support for the 3430SDP LCDKevin Hilman2009-09-23
| | | | | | | | | | | | | | | | The 3430SDP uses the same panel as the 2430SDP. The main difference are in the GPIO lines used for panel enable and backlight, and the VAUX register/commands sent to the TWL4030 power subsystem. Also, some misc. whitespace cleanups.

* gpiolib: allow poll() on valueDaniel Glöckner2009-09-23
| | | | | | | | | | | | | | | | | | | | | | | Many gpio chips allow to generate interrupts when the value of a pin changes. This patch gives usermode application the opportunity to make use of this feature by calling poll(2) on the /sys/class/gpio/gpioN/value sysfs file. The edge to trigger can be set in the edge file in the same directory. Possible values are "none", "rising", "falling", and "both". Using level triggers is not possible with current sysfs since nothing changes the GPIO value (and the IRQ keeps triggering). Edge triggering will "just work". Note that if there was an event between read() and poll(), the poll() returns immediately. Also note that this version only supports true GPIO interrupts. Some later patch might be able to synthesize this behavior by timer-driven polling; some systems seem to need that.

* gpiolib: allow exported GPIO nodes to be named using sysfs linksJani Nikula2009-09-23
| | | | | | | | | | | | | | | | | | Commit 926b663ce8215ba448960e1ff6e58b67a2c3b99b (gpiolib: allow GPIOs to be named) already provides naming on the chip level. This patch provides more flexibility by allowing multiple names where ever in sysfs on a per GPIO basis.

* rtc: add boot_timesource sysfs attributeMatthew Garrett2009-09-23
| | | | | | | | | | | | | | | | CONFIG_RTC_HCTOSYS allows the kernel to read the system time from the RTC at boot and resume, avoiding the need for userspace to do so. Unfortunately userspace currently has no way to know whether this configuration option is enabled and thus cannot sensibly choose whether to run hwclock itself or not. Add a hctosys sysfs attribute which indicates whether a given RTC set the system clock.

* spi: add support for device table matchingAnton Vorontsov2009-09-23
| | | | | | | | | | | | | | | | | | | | | | | | With this patch spi drivers can use standard spi_driver.id_table and MODULE_DEVICE_TABLE() mechanisms to bind against the devices. Just like we do with I2C drivers. This is useful when a single driver supports several variants of devices but it is not possible to detect them in run-time (like non-JEDEC chips probing in drivers/mtd/devices/m25p80.c), and when platform_data usage is overkill. This patch also makes life a lot easier on OpenFirmware platforms, since with OF we extensively use proper device IDs in modaliases.
