ARM: at91/avr32/atmel_lcdfb: add platform device-id table

2013-03-13T10:05:12Z

Add platform device-id table in order to identify the controller and determine its configuration. The currently used configuration parameters are: have_alt_pixclock - SOC uses an alternate pixel-clock calculation formula (at91sam9g45 non-ES) have_hozval - SOC has a HOZVAL field in LCDFRMCFG which is used to determine the linesize for STN displays (at91sam9261, at921sam9g10 and at32ap) have_intensity_bit - SOC uses IBGR:555 rather than BGR:565 16-bit pixel layout (at91sam9261, at91sam9263 and at91sam9rl) This allows us to remove all the remaining uses of cpu_is macros from the driver. Tested on at91sam9263 and at91sam9g45, compile-tested for other AT91-SOCs, and untested for AVR32. Signed-off-by: Johan Hovold Signed-off-by: Nicolas Ferre

ARM: at91: fix LCD-wiring mode

2013-03-13T10:05:04Z

Fix regression introduced by commit 787f9fd23283 ("atmel_lcdfb: support 16bit BGR:565 mode, remove unsupported 15bit modes") which broke 16-bpp modes for older SOCs which use IBGR:555 (msb is intensity) rather than BGR:565. The above commit removes the RGB:555-wiring hack by removing the no longer used ATMEL_LCDC_WIRING_RGB555 define. Acked-by: Peter Korsgaard Signed-off-by: Johan Hovold Signed-off-by: Nicolas Ferre

atmel_lcdfb: add board parameter specify framebuffer memory size

2008-08-12T23:07:29Z

Specify how much physically continuous, DMA capable memory will be allocated at driver initialization time. This allow to create framebuffer device with larger virtual resolution. Combine with y-panning this can be used to implement double buffering acceleration method.
