2012-08-29ENGR00221716-01 Mx6 USB host: set disconnect bit should wait for resume finishedmake shi
For i.MX6DLTO1.1 and i.MX6DQTO1.2, the disconnection-bit can only be set after the resume finished, otherwise, the remote-wake-up may fail. Because if the device not switch to High-Speed 45ohm termination resistors mode, when the disconnection detection bit is set the disconnection detection circuit will detect a high speed disconnection by mistake.

2012-08-24ENGR00221317-02 Mx6 USB host: set stop_mode_config when any USB host enabledmake shi
The Mx6 phy sometimes work abnormally after system suspend/resume if the 1V1 is off. So we should keep the 1V1 active during the system suspend if any USB host enabled. - Add stop_mode_config to 1 with refcount - Add mutex to protect the refcount and HW_ANADIG_ANA_MISC0 register - If stop_mode_config is set as 1, the otg vbus wakeup system will be supported Signed-off-by: make shi <b15407@freescale.com>
2012-07-30ENGR00218771 mx6 USB:USB disconnect issue verification on MX6QTO1.2/MX6DLTO1.1make shi
- for Rigel1.1/Arik1.2, bit 17 of HW_USBPHY_IP will be set, it will fix the issue that no wakeup between SUSP/PHCD. And the usb_platform_rh_suspend/ usb_platform_rh_resume do not need do complex software workaround, only need set/clear the workaround bit. - for Megrez , bit 17 and bit 18 of HW_USBPHY_IP will be set, it will fix the issue that no wakeup between SUSP/PHCD and disconnect after resume. No need do any software workaround. Signed-off-by: make shi <b15407@freescale.com>
2012-07-26ENGR00215520-03 Mx6:USB host: USB Host1 modulizationmake shi
- remove mx6_usb_h1_init() in board specific initialization files - Add module_init(mx6_usb_h1_init) and module_exit(mx6_usb_h1_exit) in usb_h1.c to support the usb_h1 modulization - Export necessary function which is used in usb_h1.c Signed-off-by: make shi <b15407@freescale.com>
2012-07-20ENGR00209480-4 mx6sl_usb remove the sw workaround to verify IC fixTony LIU
- add a function to tell if sw walkaround is needed for the IC bug Signed-off-by: Tony LIU <junjie.liu@freescale.com>
2012-07-20ENGR00209480-3 mx6sl_usb: fix too many wakeup interrupt issueTony LIU
modify usb wakeup interrupt number for mx6sl Signed-off-by: Tony LIU <junjie.liu@freescale.com>
2012-07-20ENGR00209480-2 mx6sl_usb:change usb irq number for mx6slTony LIU
- in mx6sl RM, the irq of usb h1(usb otg2) is 72, but in fact, it should be 74, we need change the irq special for mx6sl Signed-off-by: Tony LIU <junjie.liu@freescale.com>
2012-07-20ENGR00178939 [mx6] usb host, msleep may be called in atomic contextTony LIU
- change msleep(1) to udelay(500) - msleep may be called in atomic context, which will cause warning message Signed-off-by: Tony LIU <junjie.liu@freescale.com>
2012-07-20ENGR00177771 usb: usb wakeup enable should include both controller and phyPeter Chen
According to IC guys, it needs to enable/disable usb wakeup setting at controller and phy side together. Signed-off-by: Peter Chen <peter.chen@freescale.com>
2012-07-20ENGR00176299-1 usb host suspend/resume can't work randomlyTony LIU
MSL part - after suspend bit is set, we need to set PWD bit and clear it right now to let PHY know the state change - after suspend bit is set, disconnect detection should be clear - after set resume bit, disconnect detection should be set after 30 ms - IC issue PDM refer to TKT092876 TKT092872 Signed-off-by: Tony LIU <junjie.liu@freescale.com>
2012-07-20ENGR00176147-2: usb: pass the wakeup event to pdataPeter Chen
The host driver needs to differentiate wakeup event. Signed-off-by: Peter Chen <peter.chen@freescale.com>
2012-07-20ENGR00171027-1 [USB_HOST]after plug in/out on the hub,host can't workTony LIU
This issue will happen only when suspend bit is set but phcd is not set The root cause of this issue is the IC defect. - If the suspend bit is set without phcd bit set, host controller can't resume normally - The workaround is after set suspend bit, we need set the following bit in USB PHY at once: HW_USBPHY_PWD_RXPWDRX HW_USBPHY_PWD_RXPWDDIFF HW_USBPHY_PWD_RXPWD1PT1 HW_USBPHY_PWD_RXPWDENV HW_USBPHY_PWD_TXPWDv2I HW_USBPHY_PWD_TXPWDIBIAS HW_USBPHY_PWD_TXPWDFS - Furthermore, after resume, we must clear these bits during the K state - IC has no plan to fix this issue - This issue only happen on MX6Q/MX28 MSL part Signed-off-by: Tony LIU <junjie.liu@freescale.com>
2012-07-20ENGR00161383 [MX6Q] USB OTG: enable OTG drivermake shi
Enable OTG driver on mx6q board Signed-off-by: make shi <b15407@freescale.com>
2012-07-20ENGR00156766 [MX6Q]USB: Enable USB host1 functionmake shi
Add necessary implement to Enable USB host1 function Signed-off-by: make shi <b15407@freescale.com>
2012-07-20ENGR00153856 [mx6q]platform data is not correctly initializedTony Lin
wakeup_pdata is initialized after device register, thus the field can't be initialized correctively. change to the correct sequence. Signed-off-by: Tony Lin <tony.lin@freescale.com>
2012-07-20ENGR00152915-1 mx6q-usb: refine usb phy usagePeter Chen
(Fixed the bug that PLL7 lock failed after usb enters low power mode) After confirming with IC guys, the phy clock should be used like below: - OTG phy clock EN_USB_CLKS: should be also enabled PLL3 power: Enable/Disable on the fly - Host1 phy clock EN_USB_CLKS and PLL7 power should be also enabled at the initialization PLL7 power will be totally controller by IC Signed-off-by: Peter Chen <peter.chen@freescale.com>
2012-07-20ENGR00152493-1 mx6q: add usb functionPeter Chen
Changes at MSL - Add usb code for mx6q - Usb host functions (keyboard and u-disk) are verified - USB host low power mode and wakeup are supported - defconfig for otg port is for host port - Using upstream platform device register method - Delete some useless code, and fix the warning during building Signed-off-by: Peter Chen <peter.chen@freescale.com>
