The chipidea i.MX driver is split into two drivers. The ci_hdrc_imx driver handles the chipidea cores and the usbmisc_imx driver handles the noncore registers common to all chipidea cores (but SoC specific). Current flow is: - usbmisc sets an ops pointer in the ci_hdrc_imx driver during probe - ci_hdrc_imx checks if the pointer is valid during probe, if yes calls the functions in the ops pointer. - usbmisc_imx calls back into the ci_hdrc_imx driver to get additional data This is overly complicated and has problems if the drivers are compiled as modules. In this case the usbmisc_imx driver can be unloaded even if the ci_hdrc_imx driver still needs usbmisc functionality. This patch changes this by letting the ci_hdrc_imx driver calling functions from the usbmisc_imx driver. This way the symbol resolving during module load makes sure the ci_hdrc_imx driver depends on the usbmisc_imx driver. Also instead of letting the usbmisc_imx driver call back into the ci_hdrc_imx driver, pass the needed data in the first place.
