The difference it in DIDs and in a few functions. This patch adds the USB2517/i data structures to the driver, so it would have different setting depending on the device discovered on i2c-bus.

Furthermore add myself as a maintainer for this driver. The datasheet can be found at the manufacturers website, see [1]. All device-tree exposed configuration features have been tested on a i.MX6 platform with a USB2512B hub.

The usb4604 device is related to the usb3503 device, but it didn't seem close enough to warrant putting both into the same file. This patch borrows some of the usb3503 structure and trims it down to just handle the optional reset gpio and adds the i2c command to put the device into hub mode.

It supports three devices: Delcom Visual Signal Indicator The driver supports generation 1 of the device only which was manufactured until 2008. Remove support for this device completely. Riso Kagaku RGB LED + Dream Cheeky Webmail Notifier These devices are HID compliant and are supported by a new USB LED driver under drivers/hid utilizing the kernel LED subsystem.

UCSI is used on several Intel Broxton SoC based platforms. Things that UCSI can be used to control include at least USB Data Role swapping, Power Role swapping and controlling of Alternate Modes on top of providing general details about the port and the partners that are attached to it. The initial purpose of the UCSI driver is to make sure USB is in host mode on desktop and server systems that are USB dual role capable, and provide UCSI interface. The goal is to integrate the driver later to an USB Type-C framework for Linux kernel, and at the same time add support for more extensive USB Type-C port control that UCSI offers, for example data role swapping, power role swapping, Alternate Mode control etc. The UCSI specification is public can be obtained from here: http://www.intel.com/content/www/us/en/io/universal-serial-bus/usb-type-c-ucsi-spec.html Signed-off-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> 2015-04-03T17:03:15+00:00 Randy Dunlap rdunlap@infradead.org 2015-04-03T00:10:55+00:00 urn:sha1:d9aab404e60d122ded979fa0b81db42fb680d867 Fix build errors when HW_RANDOM is not enabled: drivers/built-in.o: In function `chaoskey_disconnect': chaoskey.c:(.text+0x5f3f00): undefined reference to `hwrng_unregister' drivers/built-in.o: In function `chaoskey_probe': chaoskey.c:(.text+0x5f42a6): undefined reference to `hwrng_register' Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
