extcon: intel-cht-wc: Add support for Lenovo Yoga Tab 3 Pro YT3-X90F

2023-02-04T13:05:42Z

The Lenovo Yoga Tab 3 Pro YT3-X90F needs the same handling as the Lenovo Yogabook models. That is it needs the extcon code to: 1. Control the Vbus regulator and USB-role-switch for the micro-USB port's host/device mode switching. 2. Register a power_supply device so that the charger-chip driver can see what sort of charger (SDP/CDP/DCP) is connected.

Pull char/misc driver updates from Greg KH: "Here is the large set of char/misc and other driver subsystem changes for 6.2-rc1. Nothing earth-shattering in here at all, just a lot of new driver development and minor fixes. Highlights include: - fastrpc driver updates - iio new drivers and updates - habanalabs driver updates for new hardware and features - slimbus driver updates - speakup module parameters added to aid in boot time configuration - i2c probe_new conversions for lots of different drivers - other small driver fixes and additions One semi-interesting change in here is the increase of the number of misc dynamic minors available to 1048448 to handle new huge-cpu systems.

extcon: usbc-tusb320: Convert to i2c's .probe_new()

Remove use of the deprecated mask_invert flag. Inverted mask registers (where a '1' bit enables an IRQ) can be described more directly as an unmask register. Signed-off-by: Aidan MacDonald Reviewed-by: Krzysztof Kozlowski Signed-off-by: Chanwoo Choi

extcon: usbc-tusb320: Update state on probe even if no IRQ pending

2022-11-22T16:31:09Z

Currently this driver triggers extcon and typec state update in its probe function, to read out current state reported by the chip and report the correct state to upper layers. This synchronization is performed correctly, but only in case the chip indicates a pending interrupt in reg09 register. This fails to cover the situation where all interrupts reported by the chip were already handled by Linux before reboot, then the system rebooted, and then Linux starts again. In this case, the TUSB320 no longer reports any interrupts in reg09, and the state update does not perform any update as it depends on that interrupt indication. Fix this by turning tusb320_irq_handler() into a thin wrapper around tusb320_state_update_handler(), where the later now contains the bulk of the code of tusb320_irq_handler(), but adds new function parameter "force_update". The "force_update" parameter can be used by the probe function to assure that the state synchronization is always performed, independent of the interrupt indicated in reg09. The interrupt handler tusb320_irq_handler() callback uses force_update=false to avoid state updates on potential spurious interrupts and retain current behavior.

extcon: usbc-tusb320: Call the Type-C IRQ handler only if a port is registered

2022-11-08T15:45:31Z

Commit bf7571c00dca ("extcon: usbc-tusb320: Add USB TYPE-C support") added an optional Type-C interface to the driver but missed to check if it is in use when calling the IRQ handler. This causes an oops on devices currently using the old extcon interface. Check if a Type-C port is registered before calling the Type-C IRQ handler.
