extcon: ptn5150: Add usb role class support

2022-05-13T08:03:41Z

Some usb controller drivers may not support extcon but use usb role class as it's the preferred approach, so to support usb dual role switch with usb role class, add usb role class consumer support. Signed-off-by: Li Jun Reviewed-by: Krzysztof Kozlowski Signed-off-by: Chanwoo Choi

extcon: sm5502: Add support for SM5703

2022-05-13T08:03:40Z

SM5703 is another MFD from Silicon Mitus which has a very similar MUIC unit to the one in SM5502. The only difference I've noticed is slightly different configuration only enables the interrupts which are exactly the same as on SM5502. If we make use of different interrupts in the future, this can be improved by having a separate struct for SM5703, but the main functionality (detecting cable or OTG adapter) is working properly.

extcon: intel-cht-wc: Support devs with Micro-B / USB-2 only Type-C connectors

2022-02-01T13:55:12Z

So far the extcon-intel-cht-wc code has only been tested on devices with a Type-C connector with USB-PD, USB3 (superspeed) and DP-altmode support through a FUSB302 Type-C controller. Some devices with the intel-cht-wc PMIC however come with an USB-micro-B connector, or an USB-2 only Type-C connector without USB-PD. Which device-model we are running on can be identified with the new cht_wc_model intel_soc_pmic field. On models without a Type-C controller the extcon code must control the Vbus 5V boost converter and the USB role switch depending on the detected cable-type.

extcon: extcon-axp288: Use P-Unit semaphore lock for register accesses

2021-10-27T05:13:38Z

use low level P-Unit semaphore lock for axp288 register accesses directly and for more than one access a time, to reduce the number of times this semaphore is locked and released which is an expensive operation. i2c-bus to the XPower is shared between the kernel and the SoCs P-Unit. The P-Unit has a semaphore wich the kernel must lock for axp288 register accesses. When the P-Unit semaphore is locked CPU and GPU power states cannot change or the system will freeze. The P-Unit semaphore lock is already managed inside the regmap access logic, but for each access the semaphore is locked and released. So use directly iosf_mbi_(un)block_punit_i2c_access(), we are safe in doing so because nested calls to the same semaphore are turned to nops.

extcon: sm5502: Add support for SM5504

2021-06-21T09:28:01Z

SM5504 is another MUIC from Silicon Mitus that is fairly similar to SM5502. They seem to use the same register set, but: - SM5504 has some additional bits in SM5502_REG_CONTROL - SM5504 has a quite different set of interrupts - SM5504 reports USB OTG as dev_type1 = BIT(0) instead of BIT(7) Overall it's minor and we can support this by defining a separate struct sm5502_type for SM5504.

ASoC/extcon: arizona: Move arizona jack code to sound/soc/codecs/arizona-jack.c

2021-03-18T11:46:15Z

The jack handling for arizona codecs is being refactored so that it is done directly by the codec drivers, instead of having an extcon-driver bind to a separate "arizona-extcon" child-device for this. drivers/mfd/arizona-core.c has already been updated to no longer instantiate an "arizona-extcon" child-device for the arizona codecs. This means that the "arizona-extcon" driver is no longer useful (there are no longer any devices for it to bind to). This commit drops the extcon Kconfig / Makefile bits and moves drivers/extcon/extcon-arizona.c to sound/soc/codecs/arizona-jack.c . This is a preparation patch for converting the arizona extcon-driver into a helper library for letting the arizona codec-drivers directly report jack state through the standard sound/soc/soc-jack.c functions.
