      ath10k: incorporate qca4019 cal data download sequence · 3d9195ea
      由 Raja Mani 提交于 
      qca4019 calibration data is stored in the host memory and it's mandatory
to download it even before reading board id and chip id from the target.
Also, there is a need to execute otp (download and run) twice, one after
cal data download and another one after board data download.

Existing cal data file name 'cal-<bus>-<id>.bin' and device tree entry
'qcom,ath10k-calibration-data' used in ath10k has assumption that it
carries other data (like board data) also along with the calibration data.
But, qca4019 cal data contains pure calibration data (doesn't include
any other info). So, using existing same cal file name and DT entry
in qca4019 case would alter the purpose of it. To avoid this, new cal
file name 'pre-cal-<bus>-<id>.bin' and new device tree entry name
'qcom,ath10k-pre-calibration-data are introduced.

Overall qca4019's firmware download sequence would look like,

   1) Download cal data (either from a file or device tree entry)
      at the address specified by target in the host interest area
      member "hi_board_data".

   2) Download otp and run with 0x10 (PARAM_GET_EEPROM_BOARD_ID)
      as a argument.

      At this point, otp will take back up of downloaded cal data
      content in another location in the target and return valid
      board id and chip id to the host.

   3) Download board data at the address specified by target
      in host interest area member "hi_board_data".

   4) Download otp and run with 0x10000 (PARAM_FLASH_SECTION_ALL) as
      a argument.

      Now otp will apply cal data content from it's backup on top
      of board data download in step 3 and prepare final data base.

   5) Download code swap and athwlan binary content.

Above sequences are implemented (step 1 to step 4) in the name of
pre calibration configuration.

      ath10k: move cal data len to hw_params · 0b8e3c4c
      由 Raja Mani 提交于 
      ath10k_download_cal_dt() compares obtained cal data content length
against QCA988X_CAL_DATA_LEN (2116 bytes). It was written by keeping
qca988x in mind. In fact, cal data length is more chip specific.
To make ath10k_download_cal_dt() more generic and reusable for other
chipsets (like qca4019), cal data length is moved to hw_params.

      ath10k: pass cal data location as an argument to ath10k_download_cal_{file|dt} · f454add4
      由 Raja Mani 提交于 
      Both ath10k_download_cal_file() and ath10k_download_cal_dt() uses
hard coded file pointer (ar->cal_file) and device tree entry
(qcom,ath10k-calibration-data) respectively to get calibration
data content.

There is a need to use those two functions in qca4019 calibration
download sequence with different file pointer and device tree entry name.
Modify those two functions to take cal data location as an argument.
So that it can serve the purpose for other file pointer and device
tree entry.

This is just preparation before adding actual qca4019 calibration
download sequence. No functional changes.
