path: root/package/kernel/ath10k-ct/patches/201-ath10k-4.16_add-LED-and-GPIO-controlling-support-for-various-chipsets.patch

From: Sebastian Gottschall <s.gottschall@newmedia-net.de>

Adds LED and GPIO Control support for 988x, 9887, 9888, 99x0, 9984 based
chipsets with on chipset connected led's using WMI Firmware API.  The LED
device will get available named as "ath10k-phyX" at sysfs and can be controlled
with various triggers.  adds also debugfs interface for gpio control.

This patch is specific for OpenWRt base, as is use old backported package
with old wireless source. Support for QCA9984 is removed.
Reworked to use ath10k-ct custom source

v13:

* only compile tested!

* fix all checkpatch warnings

* fix commit log

* sizeof(struct ath10k_gpiocontrol) -> sizeof(*gpio)

* unsigned -> unsigned int

* remove GPIOLIB code, that should be added in a separate patch

* rename gpio.c to leds.c

* add leds.h

* rename some functions:

  ath10k_attach_led() -> ath10k_leds_register()
  ath10k_unregister_led() -> ath10k_leds_unregister()
  ath10k_reset_led_pin() -> ath10k_leds_start()

* call ath10k_leds_unregister() before ath10k_thermal_unregister() to preserve ordering

* call ath10k_leds_start() only from ath10k_core_start() and not from mac.c

* rename struct ath10k_gpiocontrol as anonymous function under struct
  ath10k::leds, no need for memory allocation

* merge ath10k_add_led() to ath10k_attach_led(), which is it's only caller

* remove #if IS_ENABLED() checks from most of places, memory savings from those were not worth it

* Kconfig help text improvement and move it lower in the menu, also don't enable it by default

* switch to set_brightness_blocking() so that the callback can sleep,
  then no need to use ath10k_wmi_cmd_send_nowait() and can take mutex
  to access ar->state

* don't touch ath10k_wmi_pdev_get_temperature()

* as QCA6174/QCA9377 are not (yet) supported don't add the command to WMI-TLV interface

* remove debugfs interface, that should be added in another patch

* cleanup includes
