Re: [PATCH v13] ath10k: add LED and GPIO controlling support for various chipsets

2018-04-06 Thread Sebastian Gottschall


Hello Kalle

you removed the call to leds_start from certain locations but you seem 
to have ignored the comment i wrote above the function call.
there is a reason why i reinitialize the gpio output state in these 
locations. the firmware for 9984 and 99xx resets the gpio registers
at certain points. this will lead to a non working led code. so you must 
set the gpio output to high again and this is the reason why the 
function is called "reset_led_pin" and not led_start

because it doesnt start the led in any way. it just resets the output state
there is only one work around you may do.
you set the gpio out register to high on every led trigger, but this is 
what i wanted to avoid to save cpu time since a wmi call is more 
expensive than just a register write.


so if you want to follow this up. remove ath10k_leds_start
and insert

ath10k_wmi_gpio_config(ar, ar->hw_params.led_pin, 0,
   WMI_GPIO_PULL_NONE, WMI_GPIO_INTTYPE_DISABLE);

in ath10k_leds_set_brightness_blocking

but in any way the function name ath10k_leds_start is wrong. it doesnt 
describe the behaviour of the function

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.

I started to wonder is this Kconfig option even needed, feels pretty
pointless. Why not just make config ATH10K depend on LED stuff, just
like ath9k already does?

You can also run checkpatch manually (sorry for the long line):

checkpatch.pl --strict -q --terse --no-summary --max-line-length=90 
--show-types --ignore 
MSLEEP,USLEEP_RANGE,PRINTK_WITHOUT_KERN_LEVEL,NETWORKING_BLOCK_COMMENT_STYLE,LINUX_VERSION_CODE,COMPLEX_MACRO,PREFER_DEV_LEVEL,PREFER_PR_LEVEL,COMPARISON_TO_NULL,BIT_MACRO,CONSTANT_COMPARISON,MACRO_WITH_FLOW_CONTROL,CONST_STRUCT,MACRO_ARG_REUSE,MACRO_ARG_PRECEDENCE
 foo.patch

I modified ath10k-check --help to print the full commandline, just
haven't pushed it out yet.

some of them are bogus. for instance they advise to use "unsigned int"

the original kernel header uses "unsigned" as api definition. so i

Sure, but using "unsigned int" won't create any harm either.


for the rest like whitespaces i will make a new version and remove them

You missed my comment in my earlier mail that I'll send the next

oh okay. thank you. then forget all the rest. i will take care of these

Sure, but using "unsigned int" won't create any harm either.

You missed my comment in my earlier mail that I'll send the next
version. I have already fixed all the warnings so let me submit it. I'll
do also some other changes.

Yes, this should be done in a separate patch with a proper commit log
explaining why it's needed.

You got even the indentation wrong in multiple functions and indentation
rules have been the same as long as I remember. And checkpatch has been
around a long time already, that should not be new to anyone submitting
patches.

Check the link I provided:
