Subject: Re: [PATCH v3] ARM: at91/dt: add dts file for sama5d36ek CMP board
Le 21/11/2016 à 06:14, Wenyou Yang a écrit :
> The sama5d36ek CMP board is the variant of sama5d3xek board.
> It is equipped with the low-power DDR2 SDRAM, PMIC ACT8865 and

> The difference of the sama5d36ek CMP dts from 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 LCD isn't supported due to the pins for LCD are conflicted
