Subject: ARM: at91/dt: add peripherals to the at91sam9rlek board
X-Git-Tag: firefly_0821_release~176^2~3465^2~44^2~30^2~8
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=3d293138f6793a87594be2d74191b6645421bc65;p=firefly-linux-kernel-4.4.55.git

ARM: at91/dt: add peripherals to the at91sam9rlek board

This adds support for:
 - SPI
 - Dataflash
 - LCD
 - i2c
 - ADC
 - Touchscreen
 - USB gadget
 - PWM

Also it switches the ds1 and ds2 leds to PWM control.
