fbdev: move FBIO_WAITFORVSYNC to linux/fb.h

2010-05-25T15:07:09Z

FBIO_WAITFORVSYNC is currently implemented by matroxfb, atyfb, intelfb and more. All of them keep redefining the same FBIO_WAITFORVSYNC macro over and over again, so move it to linux/fb.h and clean up those duplicate defines.

fbdev: da8xx/omap-l1xx: implement double buffering

2010-05-25T15:07:09Z

This work includes the following: - Implement handler for FBIO_WAITFORVSYNC ioctl. - Allocate the data and palette buffers separately. A consequence of this is that the palette and data loading is now done in different phases. And that the LCD must be disabled temporarily after the palette is loaded but this will only happen once after init and each time the palette is changed. I think this is OK. - Allocate two (ping and pong) framebuffers from memory. - Add pan_display handler which toggles the LCDC DMA registers between the ping and pong buffers.

broadsheetfb: support storing waveform

2010-03-12T23:52:34Z

This patch adds waveform storing capability to broadsheetfb. It uses the firmware class to retrieve the waveform, and the request to initiate the waveform storing is done via a driver sysfs entry, loadstore_waveform. Broadsheet is a framebuffer device. It is slightly different from a typical framebuffer controller that drives a normal TFT-LCD display. Most E-Ink display panels require a waveform in order to function. That is, in order to drive the state of a pixel to black, gray, or white, a specific waveform is utilized. Basically, that waveform represents the specific E-field wiggling needed to get the pixel to its optimal state given current temperature, and its previous state. TN/IPS-LCDs use a similar concept but the driving waveform is sufficiently simple that it is internalized in the TFT source/gate driver. These E-Ink waveforms are specific to a production batch. That is, a batch of display films are produced, then they get characterized and a waveform is generated for that batch. Broadsheet, typically, is attached to its private SPI flash which is then flashed with this waveform. Users won't be able to see the waveform and typically won't ever need to know about it. If however, the display panel attached to broadsheet is changed out, then they will need to update their waveform. That would typically be done at a factory or repair facility rather than by a user.

broadsheetfb: add MMIO hooks

2010-03-12T23:52:34Z

Allow boards with GP-MMIO controllers to provide hooks to broadsheetfb in order to offload cmd/data writes and data reads instead of relying only on host based GPIO wiggling.

broadsheetfb: add multiple panel type support

2010-03-12T23:52:32Z

Update broadsheetfb to add support for multiple panel types. The 3.7" and 6" are known to work but the 9.7" is untested due to lack of hardware. Signed-off-by: Jaya Kumar Cc: Geert Uytterhoeven Cc: Krzysztof Helt Cc: Russell King Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

davinci: fb: update the driver in preparation for addition of power management features

2009-12-16T15:20:04Z

Add a helper function to enable raster. Also add one member in the private data structure to track the current blank status, another function pointer which takes in the platform specific callback function to control panel power. These updates will help in adding suspend/resume and frame buffer blank operation features. Signed-off-by: Chaithrika U S Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
