72849d4f - usb: typec: ucsi: stm32g0: add support for stm32g0 controller

Wed, 13 Jul 2022 12:08:41 +0000

usb: typec: ucsi: stm32g0: add support for stm32g0 controllerSTM32G0 provides an integrated USB Type-C and power delivery interface.It can be programmed with a firmware to handle UCSI protocol over I2Cinterface. A GPIO is used as an interrupt line.Type-C connector can be used as a wakeup source (typically to detectchanges on the port, like attach or detach). PM suspend / resume routinesare used to enable wake irqs, and signal a wakeup event in case the IRQhas fired while in suspend. The i2c core is doing the necessaryinitialization when the "wakeup-source" flag is provided.Note: the interrupt handler shouldn't be called before the i2c bus resumes.So, the interrupts are disabled during suspend period, and re-enabledupon resume, to avoid i2c transfer while suspended, from the irq handler.Acked-by: Heikki Krogerus Signed-off-by: Fabrice Gasnier Link: https://lore.kernel.org/r/20220713120842.560902-3-fabrice.gasnier@foss.st.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/typec/ucsi/Kconfig

c1b0bc2d - usb: typec: Add support for UCSI interface

Fri, 16 Jun 2017 08:21:24 +0000

usb: typec: Add support for UCSI interfaceUCSI - USB Type-C Connector System Software Interface - is aspecification that defines set of registers and datastructures for controlling the USB Type-C ports. It'sdesigned for systems where an embedded controller (EC) is incharge of the USB Type-C PHY or USB Power Deliverycontroller. It is designed for systems with EC, but it isnot limited to them, and for example some USB Power Deliverycontrollers will use it as their direct control interface.With UCSI the EC (or USB PD controller) acts as the portmanager, implementing all USB Type-C and Power Delivery statemachines. The OS can use the interfaces for reading thestatus of the ports and controlling basic operations likerole swapping.The UCSI specification highlights the fact that it does notdefine the interface method (PCI/I2C/ACPI/etc.).Therefore the driver is implemented as library and everysupported interface method needs its own driver. Driver forACPI is provided in separate patch following this one.The initial driver includes support for all requiredfeatures from UCSI specification version 1.0 (gettingconnector capabilities and status, and support for power anddata role swapping), but none of the optional UCSI features(alternate modes, power source capabilities, and cablecapabilities).Signed-off-by: Heikki Krogerus Reviewed-by: Guenter Roeck Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/typec/ucsi/Kconfig
