Pull char/misc driver updates from Greg KH: "Here is the big set of char/misc/other driver patches for 5.7-rc1. Lots of things in here, and it's later than expected due to some reverts to resolve some reported issues. All is now clean with no reported problems in linux-next. Included in here is: - interconnect updates - mei driver updates - uio updates - nvmem driver updates - soundwire updates - binderfs updates - coresight updates - habanalabs updates - mhi new bus type and core - extcon driver updates - some Kconfig cleanups - other small misc driver cleanups and updates As mentioned, all have been in linux-next for a while, and with the last two reverts, all is calm and good" * tag 'char-misc-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (174 commits) Revert "driver core: platform: Initialize dma_parms for platform devices" Revert "amba: Initialize dma_parms for amba devices" amba: Initialize dma_parms for amba devices driver core: platform: Initialize dma_parms for platform devices bus: mhi: core: Drop the references to mhi_dev in mhi_destroy_device() bus: mhi: core: Initialize bhie field in mhi_cntrl for RDDM capture bus: mhi: core: Add support for reading MHI info from device misc: rtsx: set correct pcr_ops for rts522A speakup: misc: Use dynamic minor numbers for speakup devices mei: me: add cedar fork device ids coresight: do not use the BIT() macro in the UAPI header Documentation: provide IBM contacts for embargoed hardware nvmem: core: remove nvmem_sysfs_get_groups() nvmem: core: use is_bin_visible for permissions nvmem: core: use device_register and device_unregister nvmem: core: add root_only member to nvmem device struct extcon: axp288: Add wakeup support extcon: Mark extcon_get_edev_name() function as exported symbol extcon: palmas: Hide error messages if gpio returns -EPROBE_DEFER dt-bindings: extcon: usbc-cros-ec: convert extcon-usbc-cros-ec.txt to yaml format ...

extcon: axp288: Add wakeup support

2020-03-24T23:16:14Z

On devices with an AXP288, we need to wakeup from suspend when a charger is plugged in, so that we can do charger-type detection and so that the axp288-charger driver, which listens for our extcon events, can configure the input-current-limit accordingly.

extcon: Mark extcon_get_edev_name() function as exported symbol

2020-03-24T23:16:13Z

extcon_get_edev_name() function provides client driver to request extcon dev's name. If extcon driver and client driver are compiled as loadable modules, extcon_get_edev_name() function symbol is not visible to client driver. Hence mark extcon_find_edev_name() function as exported symbol. Signed-off-by: Mayank Rana Signed-off-by: Chanwoo Choi

extcon: palmas: Hide error messages if gpio returns -EPROBE_DEFER

2020-03-24T23:16:13Z

If the gpios are probed after this driver (e.g. if they come from an i2c expander) there is no need to print an error message. Signed-off-by: H. Nikolaus Schaller Signed-off-by: Chanwoo Choi

extcon: axp288: Convert to new X86 CPU match macros

The new macro set has a consistent namespace and uses C99 initializers instead of the grufty C89 ones. Signed-off-by: Thomas Gleixner Signed-off-by: Borislav Petkov Reviewed-by: Greg Kroah-Hartman Link: https://lkml.kernel.org/r/20200320131510.075227793@linutronix.de

extcon: arizona: Factor out microphone and button detection

2019-12-09T11:18:15Z

Continue refactoring the microphone detect handling by factoring out the handling for microphone detection and button detection into separate functions. This both makes the code a little clearer and prepares for some planned future refactoring to make the state handling in the driver more explicit.

extcon: arizona: Factor out microphone impedance into a function

2019-12-09T11:18:15Z

The microphone detection handler is very long, start breaking it up by factoring out the actual reading of the impedance value into a separate functions. Additionally, this also fixes a minor bug and ensures that the microphone timeout will be rescheduled in all error cases. Signed-off-by: Charles Keepax Signed-off-by: Chanwoo Choi

extcon: arizona: Invert logic of check in arizona_hpdet_do_id

2019-12-09T11:18:15Z

Invert the check of hpdet_acc_id at the top of arizona_hpdet_do_id to reduce the identation within the function. Signed-off-by: Charles Keepax Signed-off-by: Chanwoo Choi

extcon: arizona: Remove excessive WARN_ON

2019-12-09T11:18:14Z

A WARN_ON is very strong for simply finding a button that is out of range, downgrade this to a simple error message in the log. Signed-off-by: Charles Keepax Signed-off-by: Chanwoo Choi
