Here's a v2 replacing the last two patches in the series (the first three are unchanged since the first post). If preferred, I can repost the whole series when these patches have been acked. v2: - use clkdev to handle the lcdc bus clock - use -lcdfb suffix for device ids (e.g. "at91sam9g45-lcdfb") Thanks, Johan Johan Hovold (3): ARM: at91/avr32/atmel_lcdfb: add bus-clock entry atmel_lcdfb: move lcdcon2 register access to compute_hozval ARM: at91/avr32/atmel_lcdfb: add platform device-id table arch/arm/mach-at91/at91sam9261.c | 2 + arch/arm/mach-at91/at91sam9261_devices.c | 6 +- arch/arm/mach-at91/at91sam9263.c | 1 + arch/arm/mach-at91/at91sam9263_devices.c | 2 +- arch/arm/mach-at91/at91sam9g45.c | 2 + arch/arm/mach-at91/at91sam9g45_devices.c | 6 +- arch/arm/mach-at91/at91sam9rl.c | 1 + arch/arm/mach-at91/at91sam9rl_devices.c | 2 +- arch/avr32/mach-at32ap/at32ap700x.c | 6 +- drivers/video/atmel_lcdfb.c | 120 +++++++++++++++++++++++-------- include/video/atmel_lcdc.h | 4 +- 11 files changed, 117 insertions(+), 35 deletions(-)

Remove cpu_is macros from atmel lcdfb driver and use platform-device-id table to determine platform configuration parameters. The currently used configuration parameters are: have_alt_pixclock - SOC uses an alternate pixel-clock calculation formula (at91sam9g45 non-ES) have_bus_clk - SOC has bus clock hck1 (at91sam9261, at921sam9g10 and at32ap) 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) Tested on at91sam9g45, compile-tested for other AT91 SOCs, and untested for AVR32.
