11:31 <dhruvag2000> @pivi: regarding our discussions around gpio-keys based main IO wakeup, Thanks to @tmlind_ we have patches posted upstream to enable gpio-keys wake IRQ support:

11:32 <dhruvag2000> You can refer to my overlay here for example usage: https://github.com/DhruvaG2000/dbg-linux/blob/gpio_key_trials/arch/arm64/boot/dts/ti/k3-am625-sk-main-gpio-wakeup.dtso

15:03 <pivi> dhruvag2000: nice, that pretty cool thanks. I hope to be able to test soon, at the moment our board is not able to suspend at all, I assume this is something missing, but I did not have the chance to look into that yet

15:04 <pivi> dhruvag2000: no `wakeup-source;` in the key node ?

15:05 <dhruvag2000> I don't believe that's required, since we are naming the pmx interrupt as "wake"

15:07 <dhruvag2000> *wakeup

15:10 <dhruvag2000> What you're looking for essentially is the wakeup: irqs in proc/interrupts:

15:10 <dhruvag2000> root@am62xx-evm:~# grep wakeup /proc/interrupts

15:10 <dhruvag2000> ```

15:10 <dhruvag2000> 2800000.serial:wakeup

15:10 <dhruvag2000> 240: 0 0 0 0 pinctrl 456 Edge

15:10 <dhruvag2000> 429: 0 0 0 0 pinctrl 416 Edge

15:10 <dhruvag2000> WKGPIO:wakeup

15:11 <dhruvag2000> ```

15:40 <dhruvag2000> @tmlind_: has beautifully explained it in the commit message: https://lore.kernel.org/all/20230811110432.3968-2-tony@atomide.com/

18:40 <sukrutb> tmlind_: I am working on Hibernation on BeaglePlay AM625 on 6.5.0-rc4. But dpm_run_callback() fails in omap8250_suspend+0x0/0x128 returns -16. Tried tty-linus branch but same error. This was working in 6.4.0-rc6. is it a regression or am I missing something. PF full log at https://gist.github.com/sukrutb/203f68b5e3e7215d784b261074bedfe4

22:55 <NishanthMenon> pivi: https://lore.kernel.org/linux-arm-kernel/169179274928.1340235.2380026214492639228.b4-ty@ti.com/ - we will take a risk and try this out

22:56 <NishanthMenon> have a great weekend folks.. will send a PR once i see kernelci doing good on next.
