The bug was introduced by commit id (ae2c07aaf74: davinci_mdio: runtime PM support). Now, the reason why it didn't impact functionality is, the patch has been tested on AM335x-EVM and BeagleBone platform while submitting; and in case of AM335x the MDIO driver doesn't control the module enable/disable part, which is handled by CPSW driver.

These sub-modules are also used in some of Davinci family of devices. Now based on requirement, use-case and available technology nodes the integration of these sub-modules varies across devices. So coming back to Linux net driver, currently separate and independent platform devices & drivers for CPSW and MDIO is implemented. In case of Davinci they both has separate control, from resources perspective, like clock. In case of AM33XX, the resources are shared and only one register bit-field is provided to control module/clock enable/disable, makes it difficult to handle common resource. So the solution here implemented in this patch is, Create parent<->child relationship between both the drivers, making CPSW as a parent and MDIO as its child and enumerate all the child nodes under CPSW module. Both the drivers will function exactly the way it was operating before, including runtime-pm functionality. No change is required in MDIO driver (for that matter to any child driver). As this is only supported during DT boot, the parent<->child relationship is created and populated in DT execution flow. The only required change is inside DTS file, making MDIO as a child to CPSW node.
