[openwrt/openwrt.git] /
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
