usb/ehci-mxc: add missing inclusion of mach/hardware.h

2011-08-08T19:34:45+00:00

As cpu_is_mx stuff is being used in the driver, header mach/hardware.h should be explicitly included. The missing of the header is causing today's linux-next build error as bleow.

USB: EHCI: Support controllers with big endian capability regs

2011-05-03T18:43:21+00:00

The two first HC capability registers (CAPLENGTH and HCIVERSION) are defined as one 8-bit and one 16-bit register. Most HC implementations have selected to treat these registers as part of a 32-bit register, giving the same layout for both big and small endian systems. This patch adds a new quirk, big_endian_capbase, to support controllers with big endian register interfaces that treat HCIVERSION and CAPLENGTH as individual registers.

ARM i.MX ehci: do ehci init in board specific functions

2011-02-11T07:40:45+00:00

The mxc-ehci driver calls SoC specific phy initialization right after calling board specific initialization. To offer greater flexibility for boards to setup the phy and to get rid of some unnecessary flags in platform data this patch lets the boards call the SoC specific phy initialization and remove it from the driver.

USB: ehci-mxc: Setup portsc register prior to accessing OTG viewport

2010-12-16T21:37:48+00:00

In order to read/write to the i.MX OTG viewport register it is necessary to setup the PORTSCx register first. By default i.MX OTG port is configured for USB serial PHY. In order to use a ULPI PHY the PORTSCx register needs to be configured properly. commit 724c852 (USB: ehci/mxc: compile fix) placed the PORTSC setup after the OTG viewport is accessed and this causes ULPI read/write to fail. Revert the PORTSC setup order. Tested on a MX31PDK board with a ISP1504 transceiver: ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver mxc-ehci mxc-ehci.0: initializing i.MX USB Controller ULPI transceiver vendor/product ID 0x04cc/0x1504 Found NXP ISP1504 ULPI transceiver.
