usb: chipidea: refine PHY operation

2014-02-25T01:07:52Z

- Delete global_phy due to we can get the phy from phy layer now - using devm_usb_get_phy to instead of usb_get_phy - delete the otg_set_peripheral, which should be handled by otg layer Signed-off-by: Peter Chen Signed-off-by: Greg Kroah-Hartman

usb: chipidea: add freescale imx28 special write register method

2014-01-13T23:55:19Z

According to Freescale imx28 Errata, "ENGR119653 USB: ARM to USB register error issue", All USB register write operations must use the ARM SWP instruction. So, we implement special hw_write and hw_test_and_clear for imx28. Discussion for it at below: http://marc.info/?l=linux-usb&m=137996395529294&w=2 This patch is needed for stable tree 3.11+.

usb: chipidea: move malloced regmap directly into struct hw_bank

2014-01-08T00:21:06Z

Without this patch a seperate chunk of memory is allocated for the regmap array. As the regmap is always used it makes no sense to allocate a seperate memory block for it, this patch moves the regmap array directly into the struct hw_bank.

usb: chipidea: add wait vbus lower than OTGSC_BSV before role starts

2013-08-14T19:37:20Z

When the gadget role starts, we need to make sure the vbus is lower than OTGSC_BSV, or there will be an vbus interrupt since we use B_SESSION_VALID as vbus interrupt to indicate connect and disconnect. When the host role starts, it may not be useful to wait vbus to lower than OTGSC_BSV, but it can indicate some hardware problems like the vbus is still higher than OTGSC_BSV after we disconnect to host some time later (5000 milliseconds currently), which is obvious not correct.

usb: chipidea: add vbus interrupt handler

2013-08-14T19:37:20Z

We add vbus interrupt handler at ci_otg_work, it uses OTGSC_BSV(at otgsc) to know it is connect or disconnet event. Meanwhile, we introduce two flags id_event and b_sess_valid_event to indicate it is an id interrupt or a vbus interrupt.

usb: chipidea: drop "13xxx" infix

2013-06-24T23:16:55Z

"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: udc: add multiple td support to hardware_{en,de}queue

2013-06-17T20:45:47Z

This patch removes the restriction of having a limited amount of only four active tds on one endpoint. We use the linked list implementation to manage all tds which get added and removed by hardware_{en,de}queue. The removal of this restriction adds the driver to run into a hardware errata. It's possible that the hardware will still address an transfer descriptor that already got cleaned up. To solve this the patch also postpone the cleanup of processed tds by one.

usb: chipidea: udc: add the define TD_PAGE_COUNT and fix all users

2013-03-30T15:20:49Z

A static count of transfer descriptors was used everywhere in the driver with the fixed number 5. This patch adds a define, named TD_PAGE_COUNT, and replaces all users of this value. This way its possible to have only one parameter to change and limit the amount of buffer pointers per TD.

usb: chipidea: don't redefine __ffs()

chipidea's ffs_nr() is pretty much what __ffs() does. Use that one instead. Signed-off-by: Felipe Balbi [rebased on top of debug infrastructure rework] Signed-off-by: Alexander Shishkin Signed-off-by: Greg Kroah-Hartman

usb: chipidea: convert debug entries in sysfs to debugfs

2013-03-30T15:08:39Z

Currently, we have a bunch of files in sysfs that display all sorts of debugging information for the device controller, so they have to move to debugfs where they belong. The "registers" interface have been removed, since it doesn't fit into the current driver design as is and it's hardly a good idea to touch the registers from userspace anyway.
