usb: phy: mxs: remove CONFIG_USB_OTG condition for mxs_phy_is_otg_host()

2024-01-25T23:45:10Z

commit ff2b89de471da942a4d853443688113a44fd35ed upstream. When CONFIG_USB_OTG is not set, mxs_phy_is_otg_host() will always return false. This behaviour is wrong. Since phy.last_event will always be set for either host or device mode. Therefore, CONFIG_USB_OTG condition can be removed.

usb: phy: mxs: disconnect line when USB charger is attached

2023-07-25T16:24:17Z

For mxs PHY, if there is a vbus but the bus is not enumerated, we need to force the dp/dm as SE0 from the controller side. If not, there is possible USB wakeup due to unstable dp/dm, since there is possible no pull on dp/dm, such as there is a USB charger on the port.

usb: phy: mxs: fix getting wrong state with mxs_phy_is_otg_host()

2023-07-25T16:24:17Z

The function mxs_phy_is_otg_host() will return true if OTG_ID_VALUE is 0 at USBPHY_CTRL register. However, OTG_ID_VALUE will not reflect the real state if the ID pin is float, such as Host-only or Type-C cases. The value of OTG_ID_VALUE is always 1 which means device mode. This patch will fix the issue by judging the current mode based on last_event. The controller will update last_event in time.

usb: Explicitly include correct DT includes

2023-07-25T16:20:02Z

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

usb: Switch i2c drivers back to use .probe()

2023-05-29T14:53:11Z

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver. While touching hd3ss3220.c fix a minor white space issue in the definition of struct hd3ss3220_driver.

usb: phy: twl6030: Convert to platform remove callback returning void

2023-03-23T16:35:27Z

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
