    Subject[PATCH RFC 00/10] ARM: STi: Add dwmac glue and reset controller
    Date
    From: Srinivas Kandagatla <srinivas.kandagatla@st.com>

    Hi All,

    This patch series adds Ethernet support to STi series SOCs STiH415 and STiH416.
    STi SOC series integrates dwmac IP from synopsis, however there is a hardware
    glue on top of this standard IP, this glue needs to configured before the
    actual dwmac can be used.
    To add this a new driver dwmac-sti is introduced whose responsibility is to
    configure dwmac glue and before dwmac driver, this is achieved by making dwmac
    device node as child to ethernet glue node. Inspired by usb/dwc3.
    Also the glue needs to come out of softreset which is why we have added a
    softreset controller to driver which looked perfectly neat, rather then
    driving the softreset bit from the glue driver.

    Also as part of power management in glue driver, I found that there was no
    function to determine if the child device is a wakeup source or not.
    I have added a new api device_child_may_wakeup API which could be useful for
    drivers like this. "PM / wakeup : Introduce device_child_may_wakeup" patch has
    that new API and "net: stmmac:sti: Add STi SOC glue driver." glue driver uses
    this new API.

    The reason for combining all these patches in a same series is because of
    dependencies.

    This patch series is tested on B2000 and B2020 boards with STiH415, STiH416
    SOC on ethernet 100/1000 Links.

    Comments?

    Thanks,
    srini
