usb: musb: remove unused davinci support

2022-10-22T11:23:17+00:00

The musb-davinci driver was only used on dm644x, which got removed in linux-6.0. The only remaining davinci machines are da8xx devicetree based and do not use this hardware.

usb: musb: davinci: Convert to use GPIO descriptor

2020-01-15T13:47:00+00:00

The DaVinci MUSB glue contains an optional GPIO line to control VBUS power, convert this to use a GPIO descriptor and augment the EVM board file to provide this descriptor. I can't get this driver to compile properly and it depends on broken but when I didn get it to compile brokenly, it did at least not complain about THIS code being broken so I don't think I broke the driver any more than what it already is. I did away with the ifdefs that do not work with multiplatform anyway so the day someone decides to resurrect the code, the path to get it working should be easier as well since DaVinci is now multiplatform.

usb: musb: remove references to default_a of struct usb_otg

2018-05-22T10:03:25+00:00

musb drivers do not use the otg fsm framework, so referencing to otg->default_a doesn't have any effect, so remove the references. But tusb6010 glue driver uses it locally to control the vbus power, so keep the references in tusb6010 only. Signed-off-by: Bin Liu Signed-off-by: Greg Kroah-Hartman

USB: musb: Remove redundant license text

2017-11-07T14:45:01+00:00

Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

usb: musb: Convert timers to use timer_setup()

2017-11-01T15:48:10+00:00

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly. Instead of a per-device static timer variable, a spare timer "dev_timer" is added to the musb structure for devices to use for their per-device timer.

usb: musb: davinci: remove redundant code

2017-02-03T09:05:10+00:00

The session is cleared in the core whenever musb_platform_disable() is called, so clearing it in the glue driver *_musb_disable() is redundant. Signed-off-by: Bin Liu Signed-off-by: Greg Kroah-Hartman

usb: musb: Set up function pointers for DMA

2015-05-07T18:35:51+00:00

Set up function pointers for DMA so get closer to being able to build in all the DMA engines. Signed-off-by: Tony Lindgren Signed-off-by: Felipe Balbi

usb: musb: Fix up DMA related macros

2015-05-07T18:35:46+00:00

Pass struct musb to tusb_dma_omap() and is_cppi_enabled(), and add macros for the other DMA controllers. Populate the platform specific quirks with the DMA type and use it during runtime. Note that platform glue layers with no custom DMA code are tagged with MUSB_DMA_INVENTRA which may have a chance of working. Looks like the defconfigs for these use PIO_ONLY, so this should not break existing configs. Signed-off-by: Tony Lindgren Signed-off-by: Felipe Balbi

usb: move the OTG state from the USB PHY to the OTG structure

2014-11-03T16:01:25+00:00

Before using the PHY framework instead of the USB PHY one, we need to move the OTG state into another place, since it won't be available when USB PHY isn't used. This patch moves the OTG state into the OTG structure, and makes all the needed modifications in the drivers using the OTG state.
