Pull char/misc and other driver updates from Greg KH: "Here is the large set of char, misc, and other "small" driver subsystem changes for 5.17-rc1. Lots of different things are in here for char/misc drivers such as: - habanalabs driver updates - mei driver updates - lkdtm driver updates - vmw_vmci driver updates - android binder driver updates - other small char/misc driver updates Also smaller driver subsystems have also been updated, including: - fpga subsystem updates - iio subsystem updates - soundwire subsystem updates - extcon subsystem updates - gnss subsystem updates - phy subsystem updates - coresight subsystem updates - firmware subsystem updates - comedi subsystem updates - mhi subsystem updates - speakup subsystem updates - rapidio subsystem updates - spmi subsystem updates - virtual driver updates - counter subsystem updates Too many individual changes to summarize, the shortlog contains the full details. All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (406 commits) counter: 104-quad-8: Fix use-after-free by quad8_irq_handler dt-bindings: mux: Document mux-states property dt-bindings: ti-serdes-mux: Add defines for J721S2 SoC counter: remove old and now unused registration API counter: ti-eqep: Convert to new counter registration counter: stm32-lptimer-cnt: Convert to new counter registration counter: stm32-timer-cnt: Convert to new counter registration counter: microchip-tcb-capture: Convert to new counter registration counter: ftm-quaddec: Convert to new counter registration counter: intel-qep: Convert to new counter registration counter: interrupt-cnt: Convert to new counter registration counter: 104-quad-8: Convert to new counter registration counter: Update documentation for new counter registration functions counter: Provide alternative counter registration functions counter: stm32-timer-cnt: Convert to counter_priv() wrapper counter: stm32-lptimer-cnt: Convert to counter_priv() wrapper counter: ti-eqep: Convert to counter_priv() wrapper counter: ftm-quaddec: Convert to counter_priv() wrapper counter: intel-qep: Convert to counter_priv() wrapper counter: microchip-tcb-capture: Convert to counter_priv() wrapper ...

drivers: soc: xilinx: add xilinx event management driver

2021-12-03T15:08:46Z

Xilinx event management driver provides an interface to subscribe or unsubscribe for the event/callback supported by firmware. An agent can use this driver to register for Error Event, Device Event and Suspend callback. This driver only allows one agent per event to do registration. Driver will return an error in case of multiple registration for the same event. This driver gets notification from firmware through TF-A as SGI. During initialization, event manager driver register handler for SGI used for notification. It also provides SGI number info to TF-A by using IOCTL_REGISTER_SGI call to TF-A. After receiving notification from firmware, the driver makes an SMC call to TF-A to get IPI data. From the IPI data provided by TF-A, event manager identified the cause of event and forward that event/callback notification to the respective subscribed driver. After this, in case of Error Event, driver performs unregistration as firmware expecting from agent to do re-registration if the agent wants to get notified on the second occurrence of an error event. Add new IOCTL id IOCTL_REGISTER_SGI = 25 which is used to register SGI on TF-A. Older firmware doesn't have all required support for event handling which is required by the event manager driver. So add check for the register notifier version in the event manager driver. Xilinx event management driver provides support to subscribe for multiple error events with the use of Event Mask in a single call of xlnx_register_event(). Agent driver can provide 'Event' parameter value as ORed of multiple event masks to register single callback for multiple events. For example, to register callback for event=0x1 and event=0x2 for the given node, agent can provide event=0x3 (0x1 | 0x2). It is not possible to register multiple events for different nodes in a single registration call. Also provide support to receive multiple error events as in single notification from firmware and then forward it to subscribed drivers via registered callback one by one.

firmware: cs_dsp: Allow creation of event controls

2021-11-17T22:16:28Z

Some firmwares contain controls intended to convey firmware state back to the host. Whilst more infrastructure will probably be needed for these in time, as a first step allow creation of the controls, so said firmwares arn't completely rejected.

firmware: cs_dsp: Add pre_run callback

2021-11-17T22:16:22Z

The code already has a post_run callback, add a matching pre_run callback to the client_ops that is called before execution is started. This callback provides a convenient place for the client code to set DSP controls or hardware that requires configuration before the DSP core actually starts execution. Note that placing this callback before cs_dsp_coeff_sync_controls is important to ensure that any control values are then correctly synced out to the chip.

firmware: cs_dsp: Add version checks on coefficient loading

2021-11-17T22:16:21Z

The firmware coefficient files contain version information that is currently ignored by the cs_dsp code. This information specifies which version of the firmware the coefficient were generated for. Add a check into the code which prints a warning in the case the coefficient and firmware differ in version, in many cases this will be ok but it is not always, so best to let the user know there is a potential issue.
