usb: dwc3: add disable receiver detection in P3 quirk

2016-04-18T12:23:44+00:00

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.

usb: dwc3: drop FIFO resizing logic

2016-04-14T06:24:37+00:00

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

2015-10-09T21:06:59+00:00

Add a quirk to clear the GUSB2PHYCFG.ENBLSLPM bit, which controls
whether the PHY receives the suspend signal from the controller.

usb: dwc3: Add frame length adjustment quirk

2015-09-27T15:54:31+00:00

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

usb: dwc3: add hsphy_interface property

2015-05-13T17:06:42+00:00

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.

usb: dwc3: make LPM configurable in DT

2015-03-10T20:33:33+00:00

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

2014-11-03T16:03:41+00:00

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.
