Add support to request CCA stats for physical devices from firmware through HTT stats type 19. These stats give information about channel number, number of records, counters' bitmap, collection interval and different CCA counters. Sample output: ------------- echo 19 > /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats_type cat /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats HTT_PDEV_CCA_STATS_HIST_TLV (1s): chan_num = 5955 num_records = 10 valid_cca_counters_bitmap = 0xff collection_interval = 1000 HTT_PDEV_STATS_CCA_COUNTERS_TLV:(in usec) tx_frame_usec = 0 rx_frame_usec = 0 rx_clear_usec = 999955 my_rx_frame_usec = 0 usec_cnt = 999955 med_rx_idle_usec = 0 med_tx_idle_global_usec = 0 cca_obss_usec = 999955 .....

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
