* usb: host: ehci-st: Inform the reset framework that our reset line may be sharedLee Jones2016-06-301-2/+4
| | | | | | | | | | On the STiH410 B2120 development board the ST EHCI IP shares its reset line with the OHCI IP. New functionality in the reset subsystems forces consumers to be explicit when requesting shared/exclusive reset lines.

* usb: host: ehci-st: Add EHCI support for ST STB devicesPeter Griffin2014-09-231-0/+375
This patch adds the glue code required to ensure the on-chip EHCI controller works on STi consumer electronics SoC's from STMicroelectronics. It mainly manages the setting and enabling of the relevant clocks and manages the reset / power signals to the IP block.
