usb: common: add USB GPIO based connection detection driver

2019-09-03T17:01:04Z

Due to the requirement of usb-connector.txt binding, the old way using extcon to support USB Dual-Role switch is now deprecated when use Type-B connector. This patch introduces a USB GPIO based connection detection driver, used to support Type-B connector which typically uses an input GPIO to detect USB ID pin, and try to replace the function provided by the extcon-usb-gpio driver Signed-off-by: Chunfeng Yun Tested-by: Nagarjuna Kristam Reviewed-by: Linus Walleij Link: https://lore.kernel.org/r/1567070558-29417-11-git-send-email-chunfeng.yun@mediatek.com Signed-off-by: Greg Kroah-Hartman

usb: common: create Kconfig file

2019-09-03T17:00:39Z

Create Kconfig file for USB common core, and move USB_LED_TRIG and USB_ULPI_BUS configs into the new file from the parent Kconfig, it will help to add new configs later.

Patch moves switch responsible for decoding descriptor type outside snprintf. It improves code readability a little. Signed-off-by: Pawel Laszczak Signed-off-by: Felipe Balbi

usb: common: Patch simplify usb_decode_set_clear_feature function.

2019-08-29T07:54:35Z

Patch adds usb_decode_test_mode and usb_decode_device_feature functions, which allow to make more readable and simplify the usb_decode_set_clear_feature function. Signed-off-by: Pawel Laszczak Signed-off-by: Felipe Balbi

usb: common: Separated decoding functions from dwc3 driver.

2019-08-29T07:52:27Z

Patch moves some decoding functions from driver/usb/dwc3/debug.h driver to driver/usb/common/debug.c file. These moved functions include: dwc3_decode_get_status dwc3_decode_set_clear_feature dwc3_decode_set_address dwc3_decode_get_set_descriptor dwc3_decode_get_configuration dwc3_decode_set_configuration dwc3_decode_get_intf dwc3_decode_set_intf dwc3_decode_synch_frame dwc3_decode_set_sel dwc3_decode_set_isoch_delay dwc3_decode_ctrl These functions are used also in inroduced cdns3 driver. All functions prefixes were changed from dwc3 to usb. Also, function's parameters has been extended according to the name of fields in standard SETUP packet. Additionally, patch adds usb_decode_ctrl function to include/linux/usb/ch9.h file. Signed-off-by: Pawel Laszczak Signed-off-by: Felipe Balbi

USB: move usb debugfs directory creation to the usb common core

2019-06-06T06:59:19Z

The USB gadget subsystem wants to use the USB debugfs root directory, so move it to the common "core" USB code so that it is properly initialized and removed as needed. In order to properly do this, we need to load the common code before the usb core code, when everything is linked into the kernel, so reorder the link order of the code. Also as the usb common code has the possibility of the led trigger logic to be merged into it, handle the build option properly by only having one module init/exit function and have the common code initialize the led trigger if needed.

usb: introduce usb_ep_type_string() function

2019-03-26T07:45:03Z

In some places, the code prints a human-readable USB endpoint transfer type (e.g. "bulk"). This involves a switch statement sometimes wrapped around in ({ ... }) block leading to code repetition. To make this scenario easier, here introduces usb_ep_type_string() function, which returns a human-readable name of provided endpoint type. It also changes a few places switch was used to use this new function. Signed-off-by: Chunfeng Yun Signed-off-by: Greg Kroah-Hartman

usb: common: Consider only available nodes for dr_mode

2019-03-19T13:57:32Z

There are cases where multiple device tree nodes point to the same phy node by means of the "phys" property, but we should only consider those nodes that are marked as available rather than just any node.

usb: roles: Add a description for the class to Kconfig

2018-12-17T13:07:59Z

That makes the USB role switch support option visible and selectable for the user. The class driver is also moved to drivers/usb/roles/ directory. This will fix an issue that we have with the Intel USB role switch driver on systems that don't have USB Type-C connectors: Intel USB role switch driver depends on the USB role switch class as it should, but since there was no way for the user to enable the USB role switch class, there was also no way to select that driver. USB Type-C drivers select the USB role switch class which makes the Intel USB role switch driver available and therefore hides the problem. So in practice Intel USB role switch driver was depending on USB Type-C drivers.
