s3c24xx: iPAQ rx1950 series

This patch series adds more support for iPAQ rx1950 PDA to linux:
1. LEDs driver -- it controls blue, green and red LEDs on rx1950
2. Battery driver -- adds ability to monitor and charge battery. This driver is suitable for H1940 PDA aswell (just need to write some machine specific callbacks and get voltage LUTs)

v2: removed ac registration from s3c_adc_battery driver, use pda_power instead for ac support

v3: split LEDs patch to driver and machine parts, split battery patch into battery + LED trigger parts, now battery driver can skip gpio/callbacks usage (if there's no gpio pin to determine that battery is full or if charger is enabled automatically)

v4: add .blink_set callback to LEDs driver instead of using LED_HALF value for blinking, remove LED triggers from battery driver completely (for now)

v5: restore lut_acin usage in s3c_adc_battery driver, it was accidently removed during removing AC support from driver

s3c-adc-battery is driver for monitoring
and charging battery on iPAQ H1930/H1940/RX1950.
It depends on s3c-adc driver to get battery voltage and current.

1.7.1.1

I'll try and have a look over this in the next few days.

Ben Dooks, Design & Software Engineer, Simtec Electronics

http://www.simtec.co.uk/

Applied to battery-2.6.git (for -next) with a few cosmetic fixes.

If/when Ben comment on this driver, feel free to send fixups on top of battery-2.6.git.

Also, I can take patch 4/4 if Ben ack it.

Thanks,

Thanks :)

It depends on 2/4 patch. Btw, I'm going to re-send machine specific patches in few hours (I droped rx1950-specific LEDs driver, gpio-leds is used instead).

Regards
Vasily
