| | | | | | | | Check USB Erratum A007792 applicability. If applicable, add corresponding property in the device tree via device tree fixup Signed-off-by: Nikhil Badola <nikhil.badola@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
* drivers: usb: fsl: Add USB device-tree errata frameworkNikhil Badola2014-12-11-0/+64
| | | | | | | | | | | Add a new framework for fsl usb erratum handling to standardize erratum checking only inside Uboot. Information to kernel is passed via a boolean property corresponding to erratum, hence eliminating need for code duplication inside kernel Signed-off-by: Ramneek Mehresh <ramneek.mehresh@freescale.com> Signed-off-by: Nikhil Badola <nikhil.badola@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

| | | | | | | | | | Move USB Errata checking code from "arch/powerpc" to architecture independent file "fsl_usb.h" so that errata(s) become independent of the architecture.

* fsl/usb: Increase TXFIFOTHRESH value for usb write in T4 Rev 2.0Nikhil Badola2014-04-22-0/+20
| | | | | | | | | | | Increase TXFIFOTHRES field value in TXFILLTUNING register of usb for T4 Rev 2.0. This decreases data burst rate with which data packets are posted from the TX latency FIFO to compensate for latencies in DDR pipeline during DMA. This avoids Tx buffer underruns and leads to successful usb writes Signed-off-by: Ramneek Mehresh <ramneek.mehresh@freescale.com> Signed-off-by: Nikhil Badola <nikhil.badola@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

* fsl/usb: Limit phy_type comparison to first four charactersNikhil Badola2014-02-24-1/+1
| | | | | | | | | | | | | Use first four characters for phy_type comparison. Strcmp() should not be used to check the phy_type string which maybe parsed by hwconfig_subarg(). Hwconfig_subarg() returns part of hwconfig string starting from phy_type value till the end of the string. Since phy_type could be either "utmi" or "ulpi", strncmp() should be used so that a comparison of "utmi;fsl_ddr:bank_intlv=auto" with "utmi" will succeed.

* powerpc/usb: fix bug of CPU hang when missing USB PHY clockShengzhou Liu2012-10-22-6/+16
| | | | | | | | | | | | | when missing USB PHY clock, u-boot will hang during USB initialization when issuing "usb start". We should check USBGP[PHY_CLK_VALID] bit to avoid CPU hanging in this case. Due to controller issue of PHY_CLK_VALID in ULPI mode, we set USB_EN before checking PHY_CLK_VALID, otherwise PHY_CLK_VALID doesn't work.

* usb: ehci: rework to take advantage of new lowlevel interfaceLucas Stach2012-10-15-8/+7
| | | | | | | | | | | | | | Kill off ehci-core.h It was used to specify some static controller data. To support more than one controller being active at any time we have to carry the controller data ourselfes. Change the ehci interface accordingly. NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed to do the same thing as other platforms. But the change for now is at least compile clean.
