usb: host: remove dead EHCI support for on-chip PMC MSP71xx USB controller

2021-08-18T13:32:19+00:00

Commit 1b00767fd8e1 ("MIPS: Remove PMC MSP71xx platform") deletes ./arch/mips/pmcs-msp71xx/Kconfig, including its config MSP_HAS_USB. Hence, since then, the corresponding EHCI support for on-chip PMC MSP71xx USB controller is dead code. Remove this dead driver.

USB: host: ehci-pmcmsp: Cleanup usb_hcd_msp_remove()

2020-10-28T11:32:26+00:00

usb_hcd_msp_remove() has a pdev argument which isn't used and the function is used only within this file. Remove pdev and make usb_hcd_msp_remove() static.

usb: hosts: Remove in_interrupt() from comments

2020-10-28T11:32:12+00:00

The usage of in_interrupt() in drivers is phased out for various reasons. Various comments use !in_interrupt() to describe calling context for probe() and remove() functions. That's wrong because the calling context has to be preemptible task context, which is not what !in_interrupt() describes. Cleanup the comments. While at it add the missing kernel doc argument descriptors. Signed-off-by: Ahmed S.

remove ioremap_nocache and devm_ioremap_nocache

ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig Acked-by: Arnd Bergmann

usb: add a HCD_DMA flag instead of guestimating DMA capabilities

2019-08-21T17:03:35+00:00

The usb core is the only major place in the kernel that checks for a non-NULL device dma_mask to see if a device is DMA capable. This is generally a bad idea, as all major busses always set up a DMA mask, even if the device is not DMA capable - in fact bus layers like PCI can't even know if a device is DMA capable at enumeration time. This leads to lots of workaround in HCD drivers, and also prevented us from setting up a DMA mask for platform devices by default last time we tried. Replace this guess with an explicit HCD_DMA that is set by drivers that appear to have DMA support.

USB: host: ehci: Remove redundant license text

2017-11-07T14:45:02+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.

MIPS: MSP71xx: Remove checks for two macros

2014-05-23T13:12:39+00:00

Since v2.6.39 there are checks for CONFIG_MSP_HAS_DUAL_USB and checks for CONFIG_MSP_HAS_TSMAC in the code. The related Kconfig symbols have never been added. These checks have evaluated to false for three years now. Remove them and the code they have been hiding.

usb: hcd: move controller wakeup setting initialization to individual driver

2013-12-09T02:06:46+00:00

Individual controller driver has different requirement for wakeup setting, so move it from core to itself. In order to align with current etting the default wakeup setting is enabled (except for chipidea host).
