ath.git patches for v6.11

Browse Source 
We have moved to a new group-managed repo, and this is the first pull
 request from that repo, and from me. Fingers crossed...
 
 We have some new features in ath12k along with some cleanups in ath11k
 and ath12k. Also notable are some device-tree changes to allow certain
 ath11k and ath12k devices to work with a new power sequencing
 subsystem.
 
 Major changes:
 
 ath12k
 
 * DebugFS support for datapath statistics
 * WCN7850: support for WoW (Wake on WLAN)
 * WCN7850: device-tree bindings
 
 ath11k
 
 * QCA6390: device-tree bindings

/**
* DOC: target -> host extended statistics upload
*
* The following field definitions describe the format of the HTT
* target to host stats upload confirmation message.
* The message contains a cookie echoed from the HTT host->target stats
* upload request, which identifies which request the confirmation is
* for, and a single stats can span over multiple HTT stats indication
* due to the HTT message size limitation so every HTT ext stats
* indication will have tag-length-value stats information elements.
* The tag-length header for each HTT stats IND message also includes a
* status field, to indicate whether the request for the stat type in
* question was fully met, partially met, unable to be met, or invalid
* (if the stat type in question is disabled in the target).
* A Done bit 1's indicate the end of the of stats info elements.
*
*
* |31 16|15 12|11|10 8|7 5|4 0|

* |--------------------------------------------------------------|
* | type-specific stats info |
* | (see debugfs_htt_stats.h) |
* |--------------------------------------------------------------|
* Header fields:
* - MSG_TYPE
* Bits 7:0
* Purpose: Identifies this is a extended statistics upload confirmation
* message.
* Value: 0x1c
* - COOKIE_LSBS
* Bits 31:0
* Purpose: Provide a mechanism to match a target->host stats confirmation
* message with its preceding host->target stats request message.
* Value: MSBs of the opaque cookie specified by the host-side requestor
* - COOKIE_MSBS
* Bits 31:0
* Purpose: Provide a mechanism to match a target->host stats confirmation
* message with its preceding host->target stats request message.
* Value: MSBs of the opaque cookie specified by the host-side requestor
*
* Stats Information Element tag-length header fields:
* - STAT_TYPE
* Bits 7:0
* Purpose: identifies the type of statistics info held in the
* following information element
* Value: ath12k_dbg_htt_ext_stats_type
* - STATUS
* Bits 10:8
* Purpose: indicate whether the requested stats are present
* Value:
* 0 -> The requested stats have been delivered in full
* 1 -> The requested stats have been delivered in part
* 2 -> The requested stats could not be delivered (error case)
* 3 -> The requested stat type is either not recognized (invalid)
* - DONE
* Bits 11
* Purpose:
* Indicates the completion of the stats entry, this will be the last
* stats conf HTT segment for the requested stats type.
* Value:
* 0 -> the stats retrieval is ongoing
* 1 -> the stats retrieval is complete
* - LENGTH
* Bits 31:16
* Purpose: indicate the stats information size
* Value: This field specifies the number of bytes of stats information
* that follows the element tag-length header.
* It is expected but not required that this length is a multiple of
* 4 bytes.
