package/kernel/mac80211/patches/ath/974-ath10k_add-LED-and-GPIO-controlling-support-for-various-chipsets.patch

   1 From: Sebastian Gottschall <s.gottschall@newmedia-net.de>
   2
   3 Adds LED and GPIO Control support for 988x, 9887, 9888, 99x0, 9984 based
   4 chipsets with on chipset connected led's using WMI Firmware API.  The LED
   5 device will get available named as "ath10k-phyX" at sysfs and can be controlled
   6 with various triggers.  adds also debugfs interface for gpio control.
   7
   8 This patch is specific for OpenWRt base, as is use old backported package
   9 with old wireless source. Support for QCA9984 is removed and a simbol
  10 is added to local-simbol file to export the actually compile the code
  11 with the ATH10K_LEDS simbol.

  21 v13:
  22
  23 * only compile tested!
  24
  25 * fix all checkpatch warnings
  26
  27 * fix commit log
  28
  29 * sizeof(struct ath10k_gpiocontrol) -> sizeof(*gpio)
  30
  31 * unsigned -> unsigned int
  32
  33 * remove GPIOLIB code, that should be added in a separate patch
  34
  35 * rename gpio.c to leds.c
  36
  37 * add leds.h
  38
  39 * rename some functions:
  40
  41   ath10k_attach_led() -> ath10k_leds_register()
  42   ath10k_unregister_led() -> ath10k_leds_unregister()
  43   ath10k_reset_led_pin() -> ath10k_leds_start()
  44
  45 * call ath10k_leds_unregister() before ath10k_thermal_unregister() to preserve ordering
  46
  47 * call ath10k_leds_start() only from ath10k_core_start() and not from mac.c
  48
  49 * rename struct ath10k_gpiocontrol as anonymous function under struct
  50   ath10k::leds, no need for memory allocation
  51
  52 * merge ath10k_add_led() to ath10k_attach_led(), which is it's only caller
  53
  54 * remove #if IS_ENABLED() checks from most of places, memory savings from those were not worth it
  55
  56 * Kconfig help text improvement and move it lower in the menu, also don't enable it by default
  57
  58 * switch to set_brightness_blocking() so that the callback can sleep,
  59   then no need to use ath10k_wmi_cmd_send_nowait() and can take mutex
  60   to access ar->state
  61
  62 * don't touch ath10k_wmi_pdev_get_temperature()
  63
  64 * as QCA6174/QCA9377 are not (yet) supported don't add the command to WMI-TLV interface
  65
  66 * remove debugfs interface, that should be added in another patch
  67
  68 * cleanup includes
