usb: misc: usb3503: get optional clock by devm_clk_get_optional()

2019-04-19T12:24:25+00:00

When the driver tries to get optional clock, it ignores all errors except -EPROBE_DEFER, but if only ignores -ENOENT, it will cover some real errors, such as -ENOMEM, so use devm_clk_get_optional() to get optional clock. And remove unnecessary stack variable clk. Cc: Dongjin Kim Signed-off-by: Chunfeng Yun Signed-off-by: Greg Kroah-Hartman

usb: misc: usb3503: Add system sleep support in non-I2C mode

2019-01-25T09:02:50+00:00

USB3503 chip can be used without any I2C connection, what is handled by a simple platform device driver. Add support for resetting the chip (via GPIO lines) during system suspend/resume cycle by adding calls to existing suspend/resume functions used for E2C device.

usb: misc: usb3503: make sure reset is low for at least 100us

2018-01-11T17:39:52+00:00

When using a GPIO which is high by default, and initialize the driver in USB Hub mode, initialization fails with: [ 111.757794] usb3503 0-0008: SP_ILOCK failed (-5) The reason seems to be that the chip is not properly reset. Probe does initialize reset low, however some lines later the code already set it back high, which is not long enouth. Make sure reset is asserted for at least 100us by inserting a delay after initializing the reset pin during probe. Signed-off-by: Stefan Agner Cc: stable Signed-off-by: Greg Kroah-Hartman

USB: misc: Remove redundant license text

2017-11-04T10:55:38+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: misc: usb3503: Set platform data

Driver supports two paths of device instantiation: as platform and i2c device. In the platform path it lacks of storing the driver specific structure as drvdata. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Greg Kroah-Hartman

Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.
