Yes. I think atmel-pwm-bl goes away completely, and video/backlight/pwm_bl.c gets modified (slightly) to use the new PWM API and becomes the general backlight-via-PWM-peripheral solution. After that, anyone who wants to write a backend pwm_device driver suddenly can use their peripheral for backlights (and other stuff) out-of-the-box. I just glanced over drivers/video/backlight, it looks like there are a couple other implementations that could move over to Generic PWM as well. > That would be the Favr-32 board, since the atmel-pwm-bl driver was > developed for that board. > > Weird how this stuff almost was inserted almost in parallel. Indeed. But also a bit tragic--- some wasted effort. :( Not entirely weird, however, since I try to follow AVR32 as closely as I do ARM. I have an NGW100 and an STK1000, in addition to about five different ARM machines including ones based on the AT91SAM9263. These common frameworks help me slide into insanity a little more slowly. :) (I have some PPC and MIPS boards, too. Occupational hazard). b.g. -- Bill Gatliff [EMAIL PROTECTED] -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
