This won't work until those patches are applied:
https://lkml.org/lkml/2013/12/6/676
and
http://lists.infradead.org/pipermail/linux-arm-kernel/2013-December/216963.html
However, I'm wondering if it wouldn't make sense
Commit message should have been:
Adding #io-channel-cells property to lradc allows us to use the lradc as
an iio provider.

Hello,
This is v4 of the patchset that adds support to the optional divider_by_two of
LRADC channels.
Changes since v3:
- removed DT bindings for vref_mv (was the second patch of the series)
- rebased on v3.13.0-rc3
- the first patch of the previous series had been applied previously
- this
parts to build
a long decimal number.

The atmel_tsadcc driver is not used anymore, it has been replaced by at91_adc so
remove it.

atmel_tsadcc is not allowing to use the remaining ADC channels while at91_adc
does. Completely switch to at91_adc and remove the tsadcc platform_data for
at91sam9rl and at91sam9rl based boards.

num_channels and registers are not used anymore since they are defined inside
the at91_adc driver and assigned by matching the id_table.
Also, remove the mach/at91_adc.h include that is not necessary anymore.

The ADC clock needs to be defined to enable the at91_adc driver. It is defined
to the same speed that is used for atmel_tsadcc.

this is the speed used by atmel_tsadcc.
It lowers the maximum throughput rate from 44 samples per second to 12958
samples per second. It shouldn't be an issue as the CPU is not able to keep up
reading samples at that frequency.

Old ADCs, as present on the sam9rl and the sam9g45 don't have a TSMR register
and the touchscreen support should be handled differently.

Hi, this patch set adds support for SPI, LCD, i2c, ADC and touchscreen, USB
gadget and PWM on the at91sam9rlek.
The only missing piece is now audio/ac97 support, then the SoC will be entirely
supported using DT.
Alexandre Belloni (2):
ARM: at91/dt: sam9rl: add lcd, adc, usb gadget and pwm
This adds support for:
- SPI
- Dataflash
- LCD
- i2c
- ADC
- Touchscreen
- USB gadget
- PWM
Also it switches the ds1 and ds2 leds to PWM control.

stay as fall-back just because e.g. sunxi does not have the CONFIG
registers.
Shouldn't that be use nr-gpios and if not available, read the CONFIG
registers? Else, what about bogus registers ?

PWM_LOOKUP to set period an polarity. I was wondering
about adding a new macro to d that but the number of boards using it is limited
(only 3) so I guess it is ok to do that now.
The final goal would be to get rid of .pwm_period_ns in leds-pwm and pwm_bl.
