Here are a few DT improvements for the at91sam9m10g45ek.
The first patch corrects the ADC support for the at91sam9g45.
The second patch adds ADC and touchscreen support to the at91sam9m10g45ek.
The last one corrects the PWM polarity after the polarity got right in the
driver, following patch "PWM: atmel-pwm: Fix polarity handling"
Alexandre Belloni (3):
ARM: at91/dt: sam9g45: improve ADC/touchscreen support
ARM: at91/dt: at91sam9m10g45ek: add ADC and touchscreen support
ARM: at91/dt: at91sam9m10g45ek PWM leds polarity is inversed

Fixes the compatible string, adds the pinmuxing for the ADC pins.
Also, removes atmel,adc-use-external-triggers as it is not possible to remove it
unless redefining the whole adc node

The real polarity of the LEDs is inversed. The led is between 3.3v and the PWM.
It was working before because the driver was getting the duty cycle calculation
wrong.
