Enable high speed support for USB device framework and usbtty

2012-03-28T14:31:08+00:00

This patch adds the support for high speed in usb device framework and usbtty
driver. This feature has been kept within a macro CONFIG_USBD_HS, so the board
configuration files have to define this macro to enable high speed support.

Along with that specific peripheral drivers also need to define a function to
let the framework know that the enumeration has happened at high speed.
This function prototype is "int is_usbd_high_speed(void)"

USB:gadget:designware USB device controller (UDC) implementation

2012-03-18T23:08:16+00:00

The earlier usb device controller driver was specific to spear platforms. This
patch implements the usb device controller driver as a generic controller which
can be reused by other platforms using this peripheral.

sh: Fix sh7264 clock speed and related serial setting

2012-03-08T01:26:32+00:00

The generalised calculation of the serial bit rate reg also applies
to sh7264, it was just the clock speed that was set incorrectly.

USB: Use (get|put)_unaligned for accessing wMaxPacketSize

2011-12-16T20:37:17+00:00

In 9792987721c7980453fe6447c3fa6593b44f8458 Stefan describes a usecase
where the previous behavior of leaving wMaxPacketSize be unaligned
caused fatal problems.  The initial fix for this problem was incomplete
however as it showed another cases of non-aligned access that previously
worked implicitly.  This switches to making sure that all access of
wMaxPacketSize are done via (get|put)_unaligned.

In order to maintain a level of readability to the code in some cases
we now use a variable for the value of wMaxPacketSize and in others, a
macro.

usbtty: init endpoints prior to startup events

2011-12-11T13:42:00+00:00

On some usb device controllers (pxa) the endpoint configuration must be programmed prior to enable it.

tegra2: Remove unused low-level Tegra2 UART code

2011-12-09T16:30:09+00:00

This was used by the AVP in early boot but is no longer used. Unless we
plan to enable it somehow it is not needed. In any case we should try
to use the ns16550 driver instead as it has the same code.

MX: serial_mxc: cleanup removing nasty #ifdef

2011-12-06T22:59:40+00:00

The serial driver for iMX SOCs is continuosly changed if a
new SOC or not yet used port is used. CONFIG_SYS__
defines were used only to find the base address for the selected UART.
Instead of that, move the base address to the board configuration
file and drop all #ifdef from driver.

sandbox: put stdin into raw mode

This allows us to act like a serial device: we get tab chars and CTRL+C
and respond appropriately.
