From 869c597829817af4b9f85c5e4181c622918dc781 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Tue, 26 Nov 2013 13:31:14 +0100 Subject: 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.

This field contains maximum value of maxpacket supported by driver, and is set in driver probe. This value should be used by autoconfig() function, because value of field "maxpacket" is set to value from endpoint descriptor when endpoint becomes enabled. So when autoconfig() function will be called again for this endpoint, "maxpacket" value will contain wMaxPacketSize from descriptior instead of maximum packet size for this endpoint. For this reason this patch adds new field "maxpacket_limit" which contains value of maximum packet size (which defines maximum endpoint capabilities). This value is used in ep_matches() function used by autoconfig(). Value of "maxpacket_limit" should be set in UDC driver probe function, using usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function set choosen value to both "maxpacket_limit" and "maxpacket" fields. This patch modifies UDC drivers by adding support for maxpacket_limit.
