usb: tcpm: add core framework

2024-10-17T01:12:47Z

This adds TCPM framework in preparation for fusb302 support, which can handle USB power delivery messages. This is needed to solve issues with devices, that are running from a USB-C port supporting USB-PD, but not having a battery. Such a device currently boots to the kernel without interacting with the power-supply at all. If there are no USB-PD message replies within 5 seconds, the power-supply assumes the peripheral is not capable of USB-PD. It usually takes more than 5 seconds for the system to reach the kernel and probe the I2C based fusb302 chip driver. Thus the system always runs into this state. The power-supply's solution to fix this error state is a hard reset, which involves removing the power from VBUS. Boards without a battery (or huge capacitors) will reset at this point resulting in a boot loop. This imports the TCPM framework from the kernel. The porting has originally been done by Rockchip using hardware timers and the Linux kernel's TCPM code from some years ago. I had a look at upgrading to the latest TCPM kernel code, but that beast became a lot more complex due to adding more USB-C features. I believe these features are not needed in U-Boot and with multiple kthreads and hrtimers being involved it is non-trivial to port them. Instead I worked on stripping down features from the Rockchip port to an even more basic level. Also the TCPM code has been reworked to avoid complete use of any timers (Rockchip used SoC specific hardware timers + IRQ to implement delayed work mechanism). Instead the delayed state changes are handled directly from the poll loop. Note, that (in contrast to the original Rockchip port) the state machine has the same hard reset quirk, that the kernel has - i.e. it avoids disabling the CC pin resistors for devices that are not self-powered. Without that quirk, the Radxa Rock 5B will not just end up doing a machine reset when a hard reset is triggered, but will not even recover, because the CPU will loose power and the FUSB302 will keep this state because of leak voltage arriving through the RX serial pin (assuming a serial adapter is connected). This also includes a 'tcpm' command, which can be used to get information about the current state and the negotiated voltage and current.

usb: Drop old non-DM code

2024-09-18T19:00:59Z

The driver model deadline for USB was in 2019, so drop the old USB keyboard code, to avoid needing to deal with the extra code path. Drop the unnecessary #ifdef around USB_KBD_BOOT_REPORT_SIZE while we are here. Signed-off-by: Simon Glass

usb: Move SPL_USB_STORAGE Kconfig symbol to drivers/usb/

2023-05-16T23:51:39Z

usb: move CONFIG_USB_HUB_DEBOUNCE_TIMEOUT to USB

2023-03-10T16:31:31Z

This configuration setting is only relevant if the board supports USB. It should not be in the main menu but in the USB menu. The setting is only relevant in USB host mode.

usb: onboard-hub: add driver to manage onboard hub supplies

2023-01-12T15:19:53Z

The main issue the driver addresses is that a USB hub needs to be powered before it can be discovered. This is often solved by using "regulator-always-on". This driver is inspired by the Linux v6.1 driver. It only enables (or disables) the hub vdd (3v3) supply, so it can be enumerated. Scanning of the device tree is done in a similar manner to the sandbox, by the usb-uclass. DT part looks like: &usbh_ehci { ... #address-cells = <1>; #size-cells = <0>; hub@1 { compatible = "usb424,2514"; reg = <1>; vdd-supply = <&v3v3>; }; }; When the bus gets probed, the driver is automatically probed/removed from the bus tree, as an example on stm32: STM32MP> usb start starting USB...

arch: mvebu: Disable by default unused peripherals in SPL

2022-07-21T08:14:04Z

SPL on mvebu loads proper U-Boot from custom Marvell kwbimage format and therefore support for other binary formats is not required to be present in SPL. Boot source of proper U-Boot is defined by compile time options and therefore it is not required to enable all possible and unused peripherals in SPL by default. This change decrease size of SPL binaries. Signed-off-by: Pali Rohár Reviewed-by: Stefan Roese

usb: Enforce DM_USB migration for USB_HOST devices.

2021-07-19T01:05:31Z

As the deadline for migration to DM_USB, when using a USB host controller has now gone two years past the deadline, enforce migration. This is done by: - Ensuring that all host controller options (other than the very legacy old MUSB ones) now select USB_HOST. USB_HOST now enforces DM_USB and OF_CONTROL. - Remove other parts of Kconfig logic that had platforms pick DM_USB. - To keep Kconfig happy, have some select statements test for USB_HOST as well. - Re-order some Kconfig entries and menus so that we can cleanly pick host or gadget roles. For the various HCD options that have platform glue options, group them together and update dependencies in some cases. - As SPL_DM_USB is not required, on platforms that had not yet enabled it, disable it.
