[PATCH 4/4] staging: mt7621-gpio: use devm_kasprintf to set gpio banks labels
Instead of using a custom function to return desired name for gpio
use the default assigned one and concat it '-bankN' suffix using
devm_kasprintf kernel function.

[PATCH 2/4] staging: mt7621-gpio: use custom xlate function
The default gpio.of_xlate function assumes there is one gpio chip
for each devicetree node. Device tree had changed to only use one node,
which corresponds to 3 different gpio chips now. For that approach
to work we need a custom xlate function.

OK, I finally made time to dig into this.
The problem is that the default gpio.of_xlate function assumes there is
one gpio chip for each devicetree node. With this patch applied, the
one device tree node corresponds to 3 different gpio chips. For that to
work we need an xlate function.
See below for what I wrote to get it working.
With this in place:
/sys/class/gpio still contains:
export gpiochip416 gpiochip448 gpiochip480 unexport
which is a little annoying, but unavoidable I guess.
The labels on these are:
# grep . /sys/class/gpio/gpiochip4*/label
/sys/class/gpio/gpiochip416/label:1e000600.gpio
/sys/class/gpio/gpiochip448/label:1e000600.gpio
/sys/class/gpio/gpiochip480/label:1e000600.gpio
.. all the same, which is not ideal.
Your attempt to change the names doesn't work because bgpio_init() sets
the names itself. If you move the assignment to rg->chip.label to
*after* the call to bgpio_init(), the new names work:
# grep . /sys/class/gpio/gpiochip4*/label
/sys/class/gpio/gpiochip416/label:mt7621-bank2
/sys/class/gpio/gpiochip448/label:mt7621-bank1
/sys/class/gpio/gpiochip480/label:mt7621-bank0
Also with that change /proc/interrupts contains:
17: 0 0 0 0 MIPS GIC 19 mt7621-bank0,
mt7621-bank1, mt7621-bank2
and
26: 0 0 0 0 mt7621-bank2 18 reset
The first line looks good - though having "gpio" in the name might be
good. Should they be 1e000600.gpio-bankN" ??
The second is a bit weird, as this isn't bank2.
It probably makes sense to have "1e000600.gpio 18 reset" there...
There is only 1 irq chip, compared with 3 gpio chips, so a different
name is appropriate. I changed the irq chip name:
mediatek_gpio_irq_chip.name = dev_name(&pdev->dev);
though maybe that assignment should go elsewhere - maybe in
mediatek_gpio_probe() as it is only needed once.
Thanks,
NeilBrown

Nope.
You are overly indenting already correctly indented code.

Again, nope.

Re: [PATCH 3/3] drivers/speakup: Fix style and coding warnings
Interesting construct... Yeah I'm little bit rusty on my C
/programming . I understand proper coding style may be should end with
else so I wasn't sure .. however this resolved the warnings. :)
Did you compile this?
Yes I did compile however the only issue i found when I'm compiling is
modules symvers missing messages researched online and found couple of
articles that recommended to run full kernel build . Please bear with
me I'm new to this and very excited about learning and contributing.

As you touched on, the ideal situation is that Realtek solve the issue. Ping-Ke Shih is on CC and I am adding a few more contacts from the commit log. The context is that the r8822 driver fails on several platforms unless setting aspm=0 (the default is 1). https://gist.github.com/dsd/20c05f0c6d66ee2ef9bfbb17f93f18ba https://bugzilla.kernel.org/show_bug.cgi?id=199651 If we don't get a timely fix from Realtek though, I think there is a key difference between the antenna selection headache and this one. In the antenna case, there isn't a good value that you can set that will work on all systems. If you change the default behaviour you will solve the issue for some users while simultanously introducing the problem on other systems that were previously fine. However in this case, it's highly likely that setting aspm=0 (off) by default would work for everyone. It has the disadvantage of using a bit more power, but especially with the indications that this issue affects a significant number of systems, I think that having the driver working out of the box everywhere is more important. The module parameter can be left in place so that unaffected users that want to save power can set aspm=1.

As a last resort, we would do something like add quirk or something. I haven't looked at how quirks would be handled for this driver but grep for quirk to see how other drivers do it. We will have to agree to disagree. I have no idea what the vendors are doing that cause some motherboards to need a different aspm value. What I do know is that we have had to live with the idiocy of some vendors saving a few pennies by only including a single antenna, rather than two, and then making a problem by miscoding the EFUSE bit that indicates which connector is actually in use. As we have no means that I know about to detect which boxes have the problem, a module parameter was created, just as in this case. I agree that drivers should work "out of the box", but finite resources and lack of vendor cooperation make this a goal that may not be attainable.

Re: [BUG] staging: r8822be: RTL8822be can't find any wireless AP

(I list versions that we have tried) Besides, I also notice there is a comment in drivers/staging/rtlwifi/rtl8822be/sw.c rtl8822be_init_aspm_vars function. /* * This setting works for those device with * backdoor ASPM setting such as EPHY setting. * 0 - Not support ASPM, * 1 - Support ASPM, * 2 - According to chipset. */ The value 2 for ASPM interests me. It says "Enable or disable ASPM according to chipset." I tried the setting value 2 for ASPM. Here is the parameter list of r8822be: dev@endless:~$ sudo grep "" /sys/module/r8822be/parameters/* /sys/module/r8822be/parameters/aspm:2 /sys/module/r8822be/parameters/debug_level:0 /sys/module/r8822be/parameters/debug_mask:0 /sys/module/r8822be/parameters/disable_watchdog:N /sys/module/r8822be/parameters/dma64:N /sys/module/r8822be/parameters/fwlps:Y /sys/module/r8822be/parameters/ips:Y /sys/module/r8822be/parameters/msi:Y /sys/module/r8822be/parameters/swenc:N /sys/module/r8822be/parameters/swlps:N The value 2 for ASPM also works correctly on ASUS X530UN. I do not think this is a bug. Most motherboards work with the default value of 1 for aspm. A few, such as yours need a value of 0. This reason is why the module parameter exists. You need to create the options file that you mention, and you will be fine. If we were to change the default in the driver to 0, we would break many more devices than would be fixed. For anyone that might read this, the options file should be named /etc/modprobe.d/50-rtl8822be.conf and contain a single line "options rtl8822be aspm=0".

Looking at the code for _rtl_pci_update_default_setting(), the meaning of value 2 actually seems to be "enable ASPM on Intel platforms, and disable on others". But I suspect that code is not working right, because the system we are using here is Intel-based and so my expectation would be that value 2 leaves ASPM on and we would continue seeing the issue. However, Jian-Hong reports it as working. There are also some other reports that this driver doesn't work until aspm is disabled: https://bugzilla.redhat.com/show_bug.cgi?id=1464731#c21 https://ubuntuforums.org/showthread.php?t=2364383&page=4&p=13748721#post13748721 https://bugzilla.kernel.org/show_bug.cgi?id=199651 Daniel ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel

Nit: hv_vp_index is u32 *, it would make sense to use U32_MAX instead of
'-1' everywhere in this patch.

Sure, I will add the code to unlock and set the terminated_handle to
NULL and cleanup other variables.
As its error path during the cleanup flow, so i think we should
only avoid the posting of work_queue and rest of the cleanup code should
be executed to cleanup.
Something like below i.e instead of using direct return only block
code which depends on 'msg' under if condition and execute the rest of
cleanup code for all scenario.
if (!IS_ERR(msg)) {
result = wilc_enqueue_work(msg);
if (result)
netdev_err(vif->ndev, "deinit : Error(%d)\n",result);
else
wait_for_completion(&msg->work_comp);
kfree(msg);
}
destroy_workqueue(hif_workqueue);
I will include these changes and submit the patch.

(I list versions that we have tried) Besides, I also notice there is a comment in drivers/staging/rtlwifi/rtl8822be/sw.c rtl8822be_init_aspm_vars function. /* * This setting works for those device with * backdoor ASPM setting such as EPHY setting. * 0 - Not support ASPM, * 1 - Support ASPM, * 2 - According to chipset. */ The value 2 for ASPM interests me. It says "Enable or disable ASPM according to chipset." I tried the setting value 2 for ASPM.
