Add glue to control the OMAP_LDP LCD as a frame buffer device using the existing dispc.c driver under omapfb. Patch updated for mainline kernel. Note that the drivers/video/omap should be updated to pass omap_lcd_config in platform_data. The patch should also be updated to compile if twl4030 is not selected, and eventually to use the regulator framework. Fixed-by:

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. Fixed-by:

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.

The Langwell chip is the IO hub for Intel Moorestown platform which has a 64-pin gpio block device inside. It is exposed as a dedicated PCI device. We use it to control outside peripheral as well as to do IRQ demuxing. The gpio block uses MSI to send level type interrupt to IOAPIC. Signed-off-by:

Commit 926b663c (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.

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. Signed-off-by:

This adds a driver for Freescale's MXC internal real time clock modules. The code is taken from Freescale's BSPs, but modified to fit the current kernel coding mechanisms. Also, the PMIC external clock function was removed for now to not add dead bits and keep the code as simple as possible. [akpm@linux-foundation.org: make PIE_BIT_DEF[] static] Signed-off-by:

Support two new half-duplex SPI implementation restrictions, for links that talk to TX-only or RX-only devices. (Existing half-duplex flavors support both transfer directions, just not at the same time.) Move spi_async() into the spi.c core, and stop inlining it. Then make that function perform error checks and reject messages that demand more than the underlying controller can support. Based on a patch from Marek Szyprowski which did this only for the bitbanged GPIO driver. Cc: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by:

With the update to the spi_bitbang driver, the transfer setup code is being called more often, and thus is often re-doing calculations that have been done before. The SPI layer allows our driver to add its own data to each device so add a result cache to each device. This should also remove the problem where we where directly setting up registers in the setup call which meant we might overwrite the state of an extant transfer., Signed-off-by:
