From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxx> 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?
Hello Srini ll these patches are ok for me and, as you know, I have already started using them while porting other SoC. Glue logic is mandatory now! Thanks peppe
