usb: ch9: fix up MaxStreams helper

2012-01-12T19:33:38+00:00

commit 18b7ede5f7ee2092aedcb578d3ac30bd5d4fc23c upstream.

[ removed the dwc3 portion of the patch as it didn't apply to
older kernels - gregkh]

According to USB 3.0 Specification Table 9-22, if
bmAttributes [4:0] are set to zero, it means "no
streams supported", but the way this helper was
defined on Linux, we will *always* have one stream
which might cause several problems.

For example on DWC3, we would tell the controller
endpoint has streams enabled and yet start transfers
with Stream ID set to 0, which would goof up the host
side.

While doing that, convert the macro to an inline
function due to the different checks we now need.

usb: gadget: m66592-udc: add function for external controller

2011-07-08T22:08:39+00:00

M66592 has the pin of WR0 and WR1. So, if one write-pin of CPU
connects to the pins, we have to change the setting of FIFOSEL
register in the controller. If we don't change the setting,
the controller cannot send the data of odd length.

usb: gadget: r8a66597-udc: Make BUSWAIT configurable through platform data

2011-07-08T09:47:42+00:00

BUSWAIT is a 4-bit-wide value that controls the number of access waits
from the CPU to on-chip USB module. b'0000 inserts 0 wait (2 access
cycles) and b'1111 inserts 15 waits (17 access cycles, hardware
initial value), respectively.

BUSWAIT value depends on peripheral clock frequency supplied to on-chip
of each CPU, hence should be configurable through platform data.

Note that this patch assumes that b'0000 (0 wait, 2 access cycles) is
rerely used and considered as invalid. If valid 'buswait' data is not
provided by platform, initial b'1111 (15 waits, 17 access cycles) will
be applied as a safe default.

usb: gadget: udc-core: add "new-style" registration interface

2011-07-01T21:31:13+00:00

udc_start() should only trigger the internal state machine and make
minimal house keeping. Before that call udc-core calls the bind()
callback and after the callback the pullup().

udc_stop() is simillar, udc-core calls pullup(), unbind() and finally
udc_stop().

usb: gadget: add missing #include's

2011-07-01T21:31:05+00:00

When #include'd alone, 
causes a lot of compilation errors and warnings
-- all because it relies on the including code to
bring in the necessary #include's instead of
doing this itself.

usb: gadget: add SuperSpeed support to the Gadget Framework

2011-07-01T21:27:05+00:00

SuperSpeed USB has defined a new descriptor, called
the Binary Device Object Store (BOS) Descriptor. It
has also changed a bit the definition of SET_FEATURE
and GET_STATUS requests to add USB3-specific details.

This patch implements both changes to the Composite
Gadget Framework.
