2013-07-29usb: dwc3: switch to GPL v2 onlyFelipe Balbi1-28/+8
This is a Linux-only driver which makes use of GPL-only symbols. It makes no sense to maintain Dual BSD/GPL licensing for this driver. Considering that the amount of work to use this driver in any different operating system would likely be as large as developing the driver from scratch and considering that we depend on GPL-only symbols, we will switch over to a GPL v2-only license.

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 <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>
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 <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>
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 <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>

2011-12-12usb: dwc3: add a platform device aliasSebastian Andrzej Siewior1-0/+1
We can have three modules here: dwc3.ko, dwc3-omap.ko and dwc3-pci.ko. The later have already ids-aliases for probing and is fine. The omap module has alias for DT but lacks alias for the "native" platform_device. Maybe we should get rid of it and stick to the DT name? Both glue modules create a new device for which the dwc3.ko module is responsible and that one lacks the platform alias.
