2013-06-12Merge tag 'usb-for-v3.11' of ↵Greg Kroah-Hartman81-1228/+5802
git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: patches for v3.11 merge window All function drivers are now converted to our new configfs-based binding. Eventually this will help us getting rid of in-kernel gadget drivers and only keep function drivers in the kernel. MUSB was taught that it needs to be built for host-only and device-only modes too. We had this support long ago but it involved a ridiculous amount of ifdefs. Now we have a much cleaner approach. Samsung Exynos4 platform now implements HSIC support. We're introducing support for AB8540 and AB9540 PHYs. MUSB module reinsertion now works as expected, before we were getting -EBUSY being returned by the resource checks done on driver core. DWC3 now has minimum support for TI's AM437x series of SoCs. OMAP5 USB3 PHY learned one extra DPLL configuration values because that PHY is reused in TI's DRA7xx devices. We're introducing support for Faraday fotg210 UDCs. Last, but not least, the usual set of non-critical fixes and cleanups ranging from usage of platform_{get,set}_drvdata to lock improvements.

2013-06-12usb: dwc3: omap: Adds dwc3_omap_readl/writel wrappersGeorge Cherian1-57/+116
This patch adds wrappers to dwc3_omap_readl/writel calls to accomodate both OMAP5 and AM437x reg maps (It uses the cached register offsets). Also renames OMAP5 IRQ1 as IRQMISC and IRQ1 bits as IRQMISC bits. Signed-off-by: George Cherian <george.cherian@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-06-12usb: dwc3: omap: initialize the register offset values for omap5 and AM437xGeorge Cherian1-0/+57
This patch Initializes the register offset values depending on the X_MAJOR of USBOTGSS_REVISION register. Also adds register offset defines and new debug register defines. X_MAJOR is 2 for both OMAP5 and AM437x. But both have different glue register layout. Differentiate AM437x using dt compatible. Register offsets are cached in dwc3_omap struct for reg reads and writes. Signed-off-by: George Cherian <george.cherian@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-06-12usb: dwc3: omap: Adding am437x specific register map changesGeorge Cherian1-0/+6
AM437x and OMAP5 dwc3 subsytem have different register map. Major differences are as follows. OMAP5 has one main interrupt and one misc interrupt Aegis has four main interrupts and one misc interrupt. Miscellanous Interrupt offsets are changed. UTMI OTG Control and Status Registers offsets are changed. DEBUG Configuration and Status Registers are changed. The main intend of the patch is to re-use the same wrapper driver for both OMAP5 and AM437x, by using the x_major in revision register and adjusting the offsets. This patch adds the register map offsets and adds offset variables in struct dwc3_omap to cache the offsets Signed-off-by: George Cherian <george.cherian@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2013-06-10USB: serial: ports: add minor and port numberGreg Kroah-Hartman24-180/+133
The usb_serial_port structure had the number field, which was the minor number for the port, which almost no one really cared about. They really wanted the number of the port within the device, which you had to subtract from the minor of the parent usb_serial_device structure. To clean this up, provide the real minor number of the port, and the number of the port within the serial device separately, as these numbers might not be related in the future. Bonus is that this cleans up a lot of logic in the drivers, and saves lines overall.
