usb: chipidea: imx: add one fsl picophy parameter tuning implementation

2023-07-25T16:21:52Z

In some cases, the user may need to tune the rise/fall time of the high-speed transmitter waveform for USB Certification. This will add a parameter for this purpose. The value will be fetched from dtb and finally written to the register.

usb: chipidea: usbmisc: group usbmisc operations for PM

2022-10-23T12:34:53Z

As there maybe more APIs of usbmisc for suspend and resume, group them into imx_usbmisc_suspend/resume. Besides, introduced .power_lost_check API, so that proper resume operations can be performed in power lost case.

usb: chipidea: imx: add two samsung picophy parameters tuning implementation

2020-08-23T03:40:08Z

These two parameters are used to improve USB signal for board level, in this commit, we read it from the dtb, and write to related register during the initialization. Signed-off-by: Peter Chen

usb: chipidea: imx: get available runtime dr mode for wakeup setting

2020-07-28T06:12:11Z

If runtime dr_mode is not dual-role, it doesn't need to enable ID wakeup interrupt. If runtime dr_mode is host, it doesn't need to enable VBUS wakeup interrupt. With these changes, the user will not get the unexpected wakeup for single role use case. For example, the host-only use case at Micro-AB port, the controller should not be waken up by only plug in Micro-AB cable or the Micro-B cable with host. Signed-off-by: Peter Chen

usb: chipidea: introduce imx7d USB charger detection

2020-05-06T01:42:03Z

imx7d (and imx8mm, imx8mn) uses Samsung PHY and USB generic PHY driver. The USB generic PHY driver is impossible to have a charger detection for every user, so we implement USB charger detection routine at glue layer. After the detection has finished, it will notify USB PHY charger framework, and the uevents will be triggered. Signed-off-by: Jun Li Signed-off-by: Peter Chen

USB: chipidea: Use the correct style for SPDX License Identifier

2020-03-16T03:13:47Z

This patch corrects the SPDX License Identifier style in header files related to ChipIdea Highspeed Dual Role Controller. For C header files Documentation/process/license-rules.rst mandates C-like comments (opposed to C source files where C++ style should be used). Changes made by using a script provided by Joe Perches here: https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flkml.org%2Flkml%2F2019%2F2%2F7%2F46&data=02%7C01%7CPeter.Chen%40nxp.com%7Cbea69ff84b574ca6b48e08d7c8cf58cf%7C686ea1d3bc2b4c6fa92cd99c5c301635%7C0%7C0%7C637198665199494622&sdata=bk1n4%2BvnrfRS6ZDrps%2BuXiImdzaxKZ00YskBg6pjtn4%3D&reserved=0.

usb: chipidea: imx: enable vbus and id wakeup only for OTG events

If ID or VBUS is from external block, don't enable its wakeup because it isn't used at all. Signed-off-by: Li Jun Signed-off-by: Peter Chen

usb: chipidea: imx: set power polarity

2019-02-27T14:51:02Z

This patch adds support to set the power line polarity for i.MX SoCs. To let the USB controller control the power it may be necessary to configure the polarity of the power line. So far the polarity was configured by Bootloader or alternatively the power line was muxed as gpio and driven by a regulator. Also make use of of_property_read_bool.

usb: chipidea: imx: support configuring for active low oc signal

2018-12-11T01:13:09Z

The status quo on i.MX6 is that if "over-current-active-high" is specified in the device tree this is configured as expected. If the property is missing polarity isn't changed and so the polarity is kept as setup by the bootloader. Reset default is active high, so active low can only be used with help by the bootloader. On i.MX7 it is similar, but there disabling of over current detection has a similar inconsistency. This patch introduces a new property that allows to explicitly configure for active low over current detection and consistently sets this up. In the absence of an explicit configuration the bit is kept as is. On i.MX7 over current detection is used unless disabled in the device tree. Signed-off-by: Uwe Kleine-König Signed-off-by: Peter Chen
