usb: dwc3: add disable receiver detection in P3 quirk

2016-04-18T12:23:44Z

Some freescale QorIQ platforms require to disable receiver detection in P3 for correct detection of USB devices. If GUSB3PIPECTL(DISRXDETINP3) is set, Core will change PHY power state to P2 and then perform receiver detection. After receiver detection, Core will change PHY power state to P3. Same quirk would be added in dts file in future patches. Signed-off-by: Sriram Dash Signed-off-by: Rajesh Bhagat Signed-off-by: Felipe Balbi

usb: dwc3: drop FIFO resizing logic

2016-04-14T06:24:37Z

That FIFO resizing logic was added to support OMAP5 ES1.0 which had a bogus default FIFO size. I can't remember the exact size of default FIFO, but it was less than one bulk superspeed packet (<1024) which would prevent USB3 from ever working on OMAP5 ES1.0. However, OMAP5 ES1.0 support has been dropped by commit aa2f4b16f830 ("ARM: OMAP5: id: Remove ES1.0 support") which renders FIFO resizing unnecessary.

usb: dwc3: Add dis_enblslpm_quirk

2015-10-09T21:06:59Z

Add a quirk to clear the GUSB2PHYCFG.ENBLSLPM bit, which controls whether the PHY receives the suspend signal from the controller. Cc: # v3.18+ Signed-off-by: John Youn Signed-off-by: Felipe Balbi

usb: dwc3: Add frame length adjustment quirk

2015-09-27T15:54:31Z

Add adjust_frame_length_quirk for writing to fladj register which adjusts (micro)frame length to value provided by "snps,quirk-frame-length-adjustment" property thus avoiding USB 2.0 devices to time-out over a longer run Signed-off-by: Nikhil Badola Signed-off-by: Felipe Balbi

usb: dwc3: add hsphy_interface property

2015-05-13T17:06:42Z

Platforms that have configured DWC_USB3_HSPHY_INTERFACE with value 3, i.e. UTMI+ and ULPI, need to inform the driver of the actual HSPHY interface type with the property. "utmi" if the interface is UTMI+ or "ulpi" if the interface is ULPI. Signed-off-by: Heikki Krogerus Acked-by: David Cohen Signed-off-by: Felipe Balbi

usb: dwc3: make LPM configurable in DT

2015-03-10T20:33:33Z

This patch removes "Enable USB3 LPM Capability" option from Kconfig and adds snps,usb3_lpm_capable devicetree property instead of it. USB3 LPM (Link Power Management) capability is hardware property, and it's platform dependent, so if our hardware supports this feature, we want rather to configure it in devicetree than having it as Kconfig option.

usb: dwc3: make HIRD threshold configurable

2014-11-03T16:03:41Z

HIRD threshold should be configurable by different platforms. From DesignWare databook: When HIRD_Threshold[4] is set to 1b1 and HIRD value is greater than or equal to the value in HIRD_Threshold[3:0], dwc3 asserts output signals utmi_l1_suspend_n to put PHY into Deep Low-Power mode in L1. When HIRD_Threshold[4] is set to 1b0 or the HIRD value is less than HIRD_Threshold[3:0], dwc3 asserts output signals utmi_sleep_n on L1. Signed-off-by: Huang Rui Signed-off-by: Felipe Balbi
