USB: EHCI: declare hostpc register as zero-length array

2016-06-25T00:03:12+00:00

The HOSTPC extension registers found in some EHCI implementations form a variable-length array, with one element for each port. Therefore the hostpc field in struct ehci_regs should be declared as a zero-length array, not a single-element array. This fixes a problem reported by UBSAN.

usb: Create separate header for ehci-dbgp

2014-11-07T17:02:37+00:00

The FUSBH200 and FOTG210 controllers implement sufficiently EHCI- compatible debug ports to leverage ehci-dbgp from their respective drivers. Rather than including header, though, they replicate the necessary declarations in their own headers. Move the ehci-dbgp stuff into its own header as a first step towards removing this redundancy.

USB EHCI/Xen: propagate controller reset information to hypervisor

2012-09-18T16:20:48+00:00

Just like for the in-tree early console debug port driver, the hypervisor - when using a debug port based console - also needs to be told about controller resets, so it can suppress using and then re-initialize the debug port accordingly. Other than the in-tree driver, the hypervisor driver actually cares about doing this only for the device where the debug is port actually in use, i.e. it needs to be told the coordinates of the device being reset (quite obviously, leveraging the addition done for that would likely benefit the in-tree driver too).

USB: EHCI: define extension registers like normal ones

2012-06-27T02:42:11+00:00

This patch (as1562) cleans up the definitions of the EHCI extended registers to be consistent with the definitions of the standard registers. This makes the code look a lot nicer, with no functional change. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

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.

USB: ehci: remove structure packing from ehci_def

2011-05-03T17:09:32+00:00

As pointed out by Arnd Bergmann, in include/linux/usb/ehci_def.h, struct ehci_caps is defined with __attribute__((packed)) for no good reason, and this triggers undefined behaviour when using ARM's readl() on pointers to elements of this structure: http://lkml.kernel.org/r/201102021700.20683.arnd@arndb.de The same problem exists with the other two structures in ehci_def.h too, so remove the __attribute__((packed)) from all of them.

usb: host: Add EHCI driver for NVIDIA Tegra SoCs

2011-03-11T22:22:11+00:00

The Tegra 2 SoC has 3 EHCI compatible USB controllers. This patch adds the necessary glue to allow the ehci-hcd driver to work on Tegra 2 SoCs. The platform data is used to configure board-specific phy settings and to configure the operating mode, as one of the ports may be used as a otg port. For additional power saving, the driver supports powering down the phy on bus suspend when it is used, for example, to connect an internal device that use an out-of-band remote wakeup mechanism (e.g. a gpio).

USB: EHCI: EHCI 1.1 addendum: preparation

2010-08-10T21:35:35+00:00

EHCI 1.1 addendum introduced several energy efficiency extensions for EHCI USB host controllers: 1. LPM (link power management) 2. Per-port change 3. Shorter periodic frame list 4. Hardware prefetching This patch is intended to define the HW bits and debug interface for EHCI 1.1 addendum. The LPM and Per-port change patches will be sent out after this patch.
