Ranjani Sridharan e38db1a69d topology: remove dapm route from PCM dev to host comp
This route is automatically created when the host comp is created
during topology loading. So remove it to avoid duplicating
the connection in the dapm graph.

sof-logger
======

sof-logger is used to print logs delivered from FW dma_trace mechanism, by searching log
entries in *.ldc file generated by rimage. 

Every entry declared in FW is placed in elf output file (e.g. sof-apl) in 
.static_log_entries section in a form of struct defined in sof/src/include/sof/trace.h
in sof fw repo.

*.ldc file contains snd_sof_logs_header (defined in rmbox/logger_convert.c) 
following by .static_log_entries section incorporated from FW elf file (e.g. sof-apl).
snd_sof_logs_header contains basic information about .static_log_entries section
like base_address and data_length.

sof-logger works by reading entry parameters value and entries addresses from FW
dma_trace mechanism and searching suitable entry in *.ldc file by its address.

Usage sof-logger <option(s)> <file(s)>
			Display mailbox contents
-h			help
-l *.ldc_file		Specify the *.ldc file
-i in_file		Get traces from in_file, instead of the default 
			"/sys/kernel/debug/sof/etrace"
-o out_file		Specify the output file, instead of default stdout
-t			Get traces from "/sys/kernel/debug/sof/trace", instead 
			of the default "/sys/kernel/debug/sof/etrace"
-p			Get traces from stdin, instead of the default 
			"/sys/kernel/debug/sof/etrace"
-c			Set timestamp clock in MHz
-e			Enable checking firmware version with default verification file 
			"/sys/kernel/debug/sof/fw_version"
-v ver_file		Enable checking firmware version with ver_file file, 
			instead of default: "/sys/kernel/debug/sof/fw_version"
-s			Take a snapshot of state


Examples:

- Get traces from "/sys/kernel/debug/sof/etrace" file, verifies fw_version with
  "/sys/kernel/debug/sof/fw_version" and prints logs to stdout

  $ sof-logger -l ldc_file -e

- Get traces from "/sys/kernel/debug/sof/etrace" file, verifies fw_version with
  ver_file file and prints logs to stdout

  $ sof-logger -l ldc_file -v ver_file

- Get traces from "/sys/kernel/debug/sof/etrace" file and prints logs to stdout

  $ sof-logger -l ldc_file

- Get traces from "/sys/kernel/debug/sof/etrace" file and prints logs to
  out_file file

  $ sof-logger -l ldc_file -o out_file

- Get traces from "/sys/kernel/debug/sof/trace" file and prints logs to stdout

  $ sof-logger -l ldc_file -t

- Get traces from "/sys/kernel/debug/sof/trace" file and prints logs to 
  out_file file

  $ sof-logger -l ldc_file -t -o out_file

- Get traces from stdin and prints logs to stdout

  $ sof-logger -l ldc_file -p

- Get traces from stdin and prints logs to out_file file

  $ sof-logger -l ldc_file -p -o out_file

- Get traces from trace_dump file and prints logs to stdout

  $ sof-logger -l ldc_file -i trace_dump

- Get traces from trace_dump file and prints logs to out_file file

  $ sof-logger -l ldc_file -i trace_dump -o out_file

- c flag is intented for defining clock value (in MHz) used to format log 
  timestamps. By default clock value is set to 19.2 (MHz). Below example
  set clock value to 19.9 (MHz).

  $ sof-logger -l ldc_file -i trace_dump -o out_file -c 19.9
