usb: chipidea: drop "13xxx" infix

2013-06-24T23:16:55+00:00

"ci13xxx" is bad for at least the following reasons: * people often mistype it * it doesn't add any informational value to the names it's used in * it needlessly attracts mail filters This patch replaces it with "ci_hdrc", "ci_udc" or "ci_hw", depending on the situation. Modules with ci13xxx prefix are also renamed accordingly and aliases are added for compatibility. Otherwise, no functional changes.

usb: chipidea: get rid of camelcase names

2013-06-17T20:47:25+00:00

Since someone has added camelcase detection to checkpatch.pl, chipidea udc patches have been very noisy. To make everybody's life easier, this patch changes camelcase names into something more appropriate to the coding style. No functional changes.

usb: chipidea: udc: manage dynamic amount of tds with a linked list

2013-06-17T20:45:47+00:00

Instead of having a limited number of usable tds in the udc we use a linked list to support dynamic amount of needed tds for all special gadget types. This improves throughput.

usb: chipidea: fix precedence bug in ci_requests_show()

2013-03-30T15:08:40+00:00

The intent here was to have parenthesis around the (ci->hw_ep_max / 2) so that it counts like "0 1 2 0 1 2". In the current code, the mod operation happens first so it counts like "0 0 1 1 2 2".
