06:57 <krzk> GNUtoo: you could try with exposed pins, e.g. gpx2-3 used for LED. Disable it in DTS and play manually...

12:36 <GNUtoo> krzk: the issue is that I don't get that behavior with the exposed pins, everything is fine for the flash leds

12:37 <GNUtoo> The device I use is the Galaxy SIII (GT-I9300), and the issue I have is with the suspend-req GPIO which is connected to the modem (gpm2-4)

12:38 <GNUtoo> The background information is that I picked up Simon Shield's work on the modem and managed to port it to more recent kernels and I cleaned up a bit the code which apparently was not validated

12:38 <GNUtoo> *and apparently it was not validated

12:39 <GNUtoo> like I can get the same behavior than Simon, where I can boot the modem and interact with it and even get the IMEI, the SIM card is also initialized and so on, but for some reason it doesn't go out of low power mode,

12:39 <GNUtoo> and to get calls and so on I need full power

12:41 <GNUtoo> One of the GPIO is called suspend-req AND that the GPIO configuration is different for this pin between the 3.18 SMDK kernel from LineageOS/Replicant and the 5.10-rc2 kernel we use with this modem code

12:42 <GNUtoo> And when I try to change the configuration from high to low or or from low to high, once the modem initialization is finished, I can't on either sides (SMDK or 3.18)

12:42 <GNUtoo> What is strange is that the GPIO configuration does change during the modem intialization

12:43 <GNUtoo> I could still try to get a cheap device and unsolder the modem pins though, but I'm not good at unsoldering things

13:04 <GNUtoo> And by GPIO configuration I include pull up/down configuration and drive strength. I've not looked in depth at the sleep configuration though.

14:32 <GNUtoo> s/I can't on either sides (SMDK or 3.18) / I can't on either sides (SMDK or 5.10-rc2) /
