2013-07-19ENGR00271566 usb: otg: comment otg_statemachine which we do not needPeter Chen
We have not implemented fully OTG support, so we can't call otg_statemachine since the state machine may incorrect at current dual-role switch design. At existed code, it will call otg_statemachine, in fact, it doesn't need. Besides, it causes one kernel dump at Sabreauto board due to it calls gpio API at spin lock, but at Sabreauto board the USB power GPIO is expanded by MAX7310 which calls i2c read/write and will schedule itself.

2013-07-15ENGR00270802 usb: otg: delete redundant vbus off operationPeter Chen
The problem locates at: fsl_otg_start_host(fsm, 0); if (pdata->wake_up_enable) pdata->wake_up_enable(pdata, false); otg_drv_vbus(fsm, 0); fsl_otg_start_host(fsm, 0) internally calls fsl_otg_drv_vbus(), which does the same thing as otg_drv_vbus(fsm, 0). More critically, we need disable VBUS wakeup before close VBUS operation, otherwise unexpected VBUS wakeup will occur. The solution is to remove the call of fsl_otg_drv_vbus() in fsl_otg_start_host(). Signed-off-by: Peter Chen <peter.chen@freescale.com>

Since we move the debounce time into get the PHY out of low power mode function(f1ac6159, ENGR00261451-3: mx6-msl: usb: add debounce time for otgsc value), usb_debounce_id_vbus is useless now. Signed-off-by: Peter Chen <peter.chen@freescale.com>
2013-05-10ENGR00261451-4 usb: host: Fix the bug that no id INT after system resumePeter Chen
- Fix the bug that no id interrupt after system resume if we plug ID cable during the system suspend periods. - It needs to consider OTG and non-OTG condition when handling system resume. Signed-off-by: Peter Chen <peter.chen@freescale.com>
2013-05-10ENGR00261451-1 usb: host: purify platform resume handlerPeter Chen
- If the device is on the port during the system suspend, and the USB as system wakeup source is not enabled. We don't need to put the PHY into low power mode again after platform resume, since usb bus layer will handle it. If auto suspend is supported, the bus layer will put the PHY into low power mode. - Passed below two conditions for use cases, delete the useless handling code. 1. Tested plug usb devices (high/full/low speed) during the system suspend when usb wakeup is not enabled. 2. Tested unplug and replug usb devices (high/full/low speed) during the system suspended when usb wakeup is not enabled. Signed-off-by: Peter Chen <peter.chen@freescale.com>
2013-05-06ENGR00261037-2: usb: fix the bug that mark lowpower flag wronglyPeter Chen
At default, we mark lowpower as true. After PHY initialization finishes, it should mark lowpower as false. Besides, at error patch, we need to mark lowpower as true. Signed-off-by: Peter Chen <peter.chen@freescale.com>
2013-05-06ENGR00261037-1: usb: usb host works abnormal after unload gadget modulePeter Chen
If there is usb device on the OTG port when controller works at host mode, and at this time, we unload gadget module, the usbcmd.rs will be cleared, it is unexpected behavior. When the controller works at one mode(eg, host mode), the register should not be written by other mode driver (eg, devcie driver). The OTG driver does not consider this situation, and current i.mx FSL OTG driver does not support fully OTG function, so we remove the caller at fsl_otg_set_peripheral which will touch controller register.

- When take the PHY out of low power mode, it needs to call PHY's API, only set controller register is not enough for some platforms - usb_put_hcd will free hcd, all hcd related operation should be prior to it. Signed-off-by: Peter Chen <peter.chen@freescale.com>
2013-04-11ENGR00257130-7 usb: host: Disable wakeup when switch PHY from off to onPeter Chen
Disable wakeup interrupt, since there is wakeup when phcd from 1->0 if wakeup interrupt is enabled. The unexpected wakeup can be disappeared using this fix. Signed-off-by: Peter Chen <peter.chen@freescale.com>
2013-04-11ENGR00257130-3 usb: host: open the PHY when changing wakeup settingPeter Chen

Since Logitech Quickcam E3500 is defaultly listed in usb_quirk_list on current linux kernel. So the USB camera only supports reset resume, but doesn't support normal usb suspend/resume. Actually, the USB camera works abnormally after USB reset resume, but it works well after doing normal suspend/resume. Signed-off-by: make shi <b15407@freescale.com>

There is a bug at chipidea core, please see below synopsis problem title and its number. STAR 9000378958 Title: Non-Double Word Aligned Buffer Address Sometimes Causes Host to Hang on OUT Retry This problem will be showed when we use Ethernet device at host port, there is an errata ERR006308 for it. The workaround for this issue is to disable stream mode at register usbmode. Signed-off-by: Peter Chen <peter.chen@freescale.com>

2013-01-11ENGR00232755 USB: disable clock and abnormal wakeup when remove gadget drivermake shi
- In current bsp, the usb clock mismatch when rmmod gadget class driver. The clock should be turn off when gadget class driver unregister. - There is an abnormal usb wakeup interrupt happen if phy is no power without VBUS. If we unplug the usb cable after unregister usb gadget driver, it is difficult to handle the unexpected usb wakeup interrupt. SO we must call dr_discharge_line() to make sure no abnormal usb wakeup interrupt happen in usb unregister gadget class driver. Signed-off-by: make shi <b15407@freescale.com>

There is a USB hang issue when do system suspend/resume test with a USB device plug in. The issue is caused by USB host driver accessing register when clock is off. Currently set HCD_FLAG_HW_ACCESSIBLE bit before open clock in ehci_fsl_bus_resume, it cause accessing register without clock. So we should change the code call order to avoid driver access register without clock. - Set HCD_FLAG_HW_ACCESSIBLE software flag after HW clock turn on - remove some unnecessary code in ehci_fsl_pre_irq Signed-off-by: make shi <b15407@freescale.com>
2012-11-01ENGR00231965 MX6 USB CV 3.0 test failTony LIU
- For USB CV 3.0 test, the gap between the ACK of set_address and the subsequent setup packet may be very little, say 500us, and if the latency we handle the ep completion is greater than this gap, there is no response to the subsequent packet. It will cause CV test fail - There is another way to set the address, it should set the bit 24 to 1 with the right address, and then IC controller will set the address when the IN req complete instead of SW do it. It is more fast so it can fix the CV 3.0 test fail issue Signed-off-by: Tony LIU <junjie.liu@freescale.com>
