Add a framebuffer driver for Qualcomm MSM/QSD SoCs, tested on HTC Dream smartphone (aka T-Mobile G1, aka ADP1). Brian said: I did the original quick and dirty version for bringup. Rebecca took over and (re)wrote the bulk of the driver, getting things stable for production ship of Dream and Sapphire, and Dima is currently adding support for later Qualcomm chipsets (QSD8x50, etc).

Previously, the only external (to dispc.c) IRQ handler was RFBI's frame done handler. dispc's IRQ framework was very dumb: you could only have one handler, and the semantics of {request,free}_irq were odd, to say the least. The new framework allows multiple consumers to register arbitrary IRQ masks. Signed-off-by:Daniel Stone <daniel.stone@nokia.com> Signed-off-by:

Without wakeup enable omap doesn't wake up on dispc interrupts. This causes problems in a case where mpu is in sleep state and dispc interrupt fires. Signed-off-by:

Leaving interface clocks enabled causes dss pwrdm to stay in active state when mpu is in active state. This fix puts dss to sleep state when it is not needed. Earlier version broke framebuffer on 24xx. This is fixed by enabling clocks before trying to access DISPC_IRQSTATUS register. Signed-off-by:

The LCD controller (EPSON S1D13744) supports rotation (0, 90, 180 and 270 degrees) on hardware just setting the bits 0 and 1 of 0x28 register (LCD Panel Configuration Register). Now it is possible to use this caps only setting the angle degree on var rotate of fb_var_screeninfo using the FBIOPUT_VSCREENINFO ioctl. Fixed-by:

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:

Daniel Glöckner authored
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:

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:
