Also, don't reset src_cap_id upon disconnect. This makes it a a monotonically increasing value upon every connection so that clients can distinguish when a new PD session is established. Demote it to a u16 in order to have a smaller wraparound (65535). Change-Id: I622ad1155b3680d3f616d5e9a835d4c6cbca3636 Signed-off-by: Jack Pham <jackp@codeaurora.org>

This allows for checking if the request was rejected so that an error can be returned. Rename the 'swap_complete' completion variable to 'is_ready' so it can be reused in this context. Also add a mutex so that select_pdo will not contend with a dual_role swap. Change-Id: Ie8b088faa15c67915e3bd96972b4f59f0cc66afe Signed-off-by: Jack Pham <jackp@codeaurora.org>

But it introduced bug in case of no sink capablities passed from device tree as in this case, device_property_read_u32_array() returns -EINVAL. Due to this, usbpd driver probe fails as usbpd_create() returns errors. Fix this issue by checking if return value > 0 and then only try to read sink capablities from device tree. If not, use default sink capabliites defined in usbpd driver. Change-Id: I51beeba282c6e067881c664d38c2657843a1c716 Signed-off-by: Vijayavardhan Vennapusa <vvreddy@codeaurora.org>

This leads dl_aggregation size set to 0 instead of required rndis_dl_aggr_size. Hence fix this by incrementing tmp pointer for requestID to use correct offset to read max Transfer size and set DL aggregation size correctly. Also pass maxpkt_per_xfer as zero to rndis_qc_bind_config_vendor() so that UL aggregation buffer size will be set to aggregation of 15 packets. This helps in improving througput numbers.

As a result it accepts the request, goes to L1 state, and does not initiate wakeup to exit L1 state. Since host expects the device to do a remote wakeup from L1 state and the device does not initiate the wakeup, the host continues to wait and starts enumeration again because control transfer timeout occurs. Fix this issue by initiating remote wakeup before queuing the ep0 request if bus is in L1 suspend state. Also add a counter which gets incremented upon device sending remote wakeup before queuing ep0 request.

Controller starts in Super Speed mode (higher core clock rate) and it will operate in super or high or full or low speed upon device connection. Update the core clock rate based on bus speed to allows system to operate in better low power state (such as SVS1/SVS2 based on system configuration). High Speed rate for core clock is programmed from dtsi. Super Speed rate will be used if High speed core clock rate is not provided for backward compatibility.

This will avoid any leakage and makes sure that DP/DM lines are in high-z state. Change-Id: I55dbe8d42ce9e56046bd7c99e17c2ec6f368c9a6 Signed-off-by: Hemant Kumar <hemantk@codeaurora.org>

Upon set_alt if thread gets a chance to run before dwc3_ep0_delegate_req() returns USB_GADGET_DELAYED_STATUS and sets delayed_status flag to true status phase request never gets queued. This results into device enumeration failure followed by a bus resets. Fix this issue by adding delay before calling usb_composite_setup_continue() to queue the status phase request.

Failing to create channel can result in enumeration failure. Avoid this dependency by creating diag channel from function instance if not available. Same channel will be reused when diag char driver creates/opens the channel. Change-Id: I11debd0189d81542762af22b3d203728d2266a42 Signed-off-by: Liangliang Lu <luliang@codeaurora.org>
