2012-04-19fsl/usb: Add controller version based ULPI and UTMI phy supportRamneek Mehresh1-0/+41
Add support for ULPI and UTMI PHYs based on usb controller version info read from device-tree Example of USB Controller versioning info: Version 1.2 and below : MPC8536, MPC8315, etc Version 1.6 : P1020, P1010, P2020, P5020, etc Version 2.2 : PSC9131, PSC9132, P3060, etc No changes for non-DT users Signed-off-by: Ramneek Mehresh <ramneek.mehresh@freescale.com> Acked-by: Li Yang <leoli@freescale.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-02-25usb: Fix build error due to dma_mask is not at pdev_archdata at ARMPeter Chen1-1/+0
When build i.mx platform with imx_v6_v7_defconfig, and after adding USB Gadget support, it has below build error: CC drivers/usb/host/fsl-mph-dr-of.o drivers/usb/host/fsl-mph-dr-of.c: In function 'fsl_usb2_device_register': drivers/usb/host/fsl-mph-dr-of.c:97: error: 'struct pdev_archdata' has no member named 'dma_mask' It has discussed at: http://www.spinics.net/lists/linux-usb/msg57302.html For PowerPC, there is dma_mask at struct pdev_archdata, but there is no dma_mask at struct pdev_archdata for ARM. The pdev_archdata is related to specific platform, it should NOT be accessed by cross platform drivers, like USB. The code for pdev_archdata should be useless, as for PowerPC, it has already gotten the value for pdev->dev.dma_mask at function arch_setup_pdev_archdata of arch/powerpc/kernel/setup-common.c.

2011-11-28usb: convert drivers/usb/* to use module_platform_driver()Axel Lin1-11/+1
This patch converts the drivers in drivers/usb/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

2011-11-01usb: Add module.h to drivers/usb consumers who really use it.Paul Gortmaker1-0/+1
The situation up to this point meant that module.h was pretty much everywhere, regardless of whether you asked for it or not. We are fixing that, so give the USB folks who want it an actual include of it. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-01-23USB: ehci-fsl: Fix 'have_sysif_regs' detectionPeter Tyser1-3/+8
Previously a check was done on an ID register at the base of a CPU's internal USB registers to determine if system interface regsiters were present. The check looked for an ID register that had the format ID[0:5] == ~ID[8:13] as described in the MPC5121 User's Manual to determine if a MPC5121 or MPC83xx/85xx was being used. There are two issues with this method: - The ID register is not defined on the MPC83xx/85xx CPUs, so its unclear what is being checked on them. - Newer CPUs such as the P4080 also don't document the ID register, but do share the same format as the MPC5121. Thus the previous code did not set 'have_sysif_regs' properly which results in the P4080 not properly initializing its USB ports. Using the device tree 'compatible' node is a cleaner way to determine if 'have_sysif_regs' should be set and resolves the USB initialization issue seen on the P4080. Tested on a P4080-based system and compile tested on mpc512x_defconfig with Freescale EHCI driver enabled.

2010-10-22USB: add USB EHCI support for MPC5121 SoCAnatolij Gustschin1-0/+89
Extends FSL EHCI platform driver glue layer to support MPC5121 USB controllers. MPC5121 Rev 2.0 silicon EHCI registers are in big endian format. The appropriate flags are set using the information in the platform data structure. MPC83xx system interface registers are not available on MPC512x, so the access to these registers is isolated in MPC512x case. Furthermore the USB controller clocks must be enabled before 512x register accesses which is done by providing platform specific init callback. The MPC512x internal USB PHY doesn't provide supply voltage. For boards using different power switches allow specifying DRVVBUS and PWR_FAULT signal polarity of the MPC5121 internal PHY using "fsl,invert-drvvbus" and "fsl,invert-pwr-fault" properties in the device tree USB nodes. Adds documentation for this new device tree bindings. Signed-off-by: Anatolij Gustschin <agust@denx.de> Cc: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-10-22USB: add platform glue driver for FSL USB DR controllerAnatolij Gustschin1-0/+219
Replace FSL USB platform code by simple platform driver for creation of FSL USB platform devices. The driver creates platform devices based on the information from USB nodes in the flat device tree. This is the replacement for old arch fsl_soc usb code removed by this patch. The driver uses usual of-style binding, available EHCI-HCD and UDC drivers can be bound to the created devices. The new of-style driver additionaly instantiates USB OTG platform device, as the appropriate USB OTG driver will be added soon.
