With the move from the 3.14.52 to the 4.1 kernel the way the weim
node defines chipselects changed.
A phandle to the gpr node is needed.
Only the following 4 configuration can be specified in the ranges property:
CS0(128M), CS1 (0M), CS2(0M), CS3(0M)
CS0(64M), CS1(64M), CS2(0M), CS3(0M)
CS0(64M), CS1(32M), CS2(32M), CS3(0M)
CS0(32M), CS1(32M), CS2(32M), CS3(32M)

With /sys/class/pwm a more versatile interface to pwm exists now.
PWM<A>: pwmchip3 export 0
PWM<B>: pwmchip1 export 0
PWM<C>: pwmchip4 export 0
PWM<B>: pwmchip2 export 0
e.g. configure a 1kHz 25% on PWM<C>:
(period and duty cycle in nano seconds)
$ cd /sys/class/pwm/pwmchip3
$ echo 0 > export
$ echo 1000000 > pwm0/period
$ echo 250000 > pwm0/duty_cycle
$ echo 1 > pwm0/enable

Use the device evalspi for spidev nodes.
This prevents a lot of useless warnings that spidev should not be used.

Enable ADV7280 decoder for iMX6 modules. ADV7280 and ADV7180 have
same addresses viz. 0x21 respectively, changing the ADV7280 address
to 0x20 would result in a conflict with MAX9526. As a result enable
ADV7280 by default and disable ADV7180.

According to the datasheet the SPI clock (for read) must not exceed
1 / 55ns for i.MX6Q/D and 1 / 43ns for i.MX6DL/S.
Reflect that correctly in the device tree.
