| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | use devm_get_clk() for automatic put upon device release, check for and propagate errors when enabling clocks, must prepare clocks before they can get enabled, unprepare after disable need to use the _parent_ of the platform device for clock lookup, since this one is associated with the respective device tree node; this change remains neutral as long as a "globally" provided "usb%d_clk" item gets provided by either the PPC_CLOCK implementation or clkdev_register'ed aliases, using the correct devide and thus referencing the right DT node becomes essential when clock lookup will become based on device tree when common clock support will get introduced Signed-off-by: Gerhard Sittig <gsi@denx.de> Signed-off-by: Anatolij Gustschin <agust@denx.de>

* usb: Fix build error due to dma_mask is not at pdev_archdata at ARMPeter Chen2012-02-241-1/+0

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.

* USB: ehci-fsl: Fix 'have_sysif_regs' detectionPeter Tyser2011-01-221-3/+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.

* USB: add USB EHCI support for MPC5121 SoCAnatolij Gustschin2010-10-221-0/+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>
* USB: add platform glue driver for FSL USB DR controllerAnatolij Gustschin2010-10-221-0/+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.
