Subject[PATCH v1] ARM: at91/dt: add dts file for sama5d36ek CMP board
Date
The difference between sama5d36ek_cmp.dts and sama5d36ek.dts
is listed as below.
1. The USB host nodes are removed, that is, the USB host is disabled.
2. The gpio_keys node is added to wake up from the sleep.
3. The sama5d3xdm.dtsi isn't included, because the pins for LCD are
conflicted with one for gpio_keys.

As said in errata, "When the USB host ports are used in high speed
mode (EHCI), it is not possible to suspend the ports if no device is
attached on each port. This leads to increased power consumption even
if the system is in a low power mode." That is why the the USB host
isn't enabled.
