usb: musb: dsps: add support for suspend and resume
The dsps platform needs to save save some registers at suspend time and restore them after resume. This patch adds a struct for these registers, and also lets the musb core know that the core registers need to be saved as well. We also have to explicitly de-assert the port reset upon resume on this platform, but musb_port_reset() should not be called from glue layers. Hence, introduce a flag in struct musb_hdrc_config for this. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
