> In order to support Wake-On-Lan when using the RK3288 integrated MAC
> (with an external RGMII PHY), we need to avoid shutting down the regulator
> of the external PHY when the MAC is suspended as it's currently done in the MAC
> platform code.
> As a first step, create independant callbacks for suspend/resume rather than
> re-using exit/init callbacks. So the dwmac platform driver can behave differently
> on suspend where it might skip shutting the PHY and at module unloading.
> Then update the dwmac-rk driver to switch off the PHY regulator only if we are
> not planning to wake up from the LAN.
> Finally add the PMT interrupt to the MAC device tree configuration, so we can
> wake up the core from it when the PHY has received the magic packet.
> 
> Changes since v1:
>   * rename 'powered_down' variable into 'suspended'.
>   * fix the logic recording the PHY suspended state according to Heiko comments.

Series applied to net-next, thanks.
