I understand gpio0-10(gpio0_b2) func1 is tsadc_int...
<naobsd>
well
<naobsd>
it's rk3288 :(
<naobsd>
on rk3368, gpio0-3 is tsadc_int
<mmind00>
naobsd: yep, seems strange ... according to the manual gpio0b2 (=10) func1 is sc_rst (from the smartcard-controller most likely)
<naobsd>
then at least rk3368.dtsi otp-gpio/otp-out pinctrl is wrong
<mmind00>
naobsd: I'll ask Caesar, what is up with that (manual could also be wrong) ... of course Chinese new year just now, so it might take a bit :-)
<naobsd>
I see :)
<naobsd>
btw dwc_otg on rk3368 is working?
<naobsd>
(in host mode)
<mmind00>
naobsd: for me it does (on my r88 board)
<naobsd>
let me try again...
<naobsd>
[ 33.647895] usb 1-1: new full-speed USB device number 3 using dwc2
<naobsd>
[ 48.828279] usb 1-1: device descriptor read/64, error -110
<naobsd>
:(
<naobsd>
ok, give up for now ;)
<naobsd>
btw R68 gpio0-1 controls board power
<naobsd>
it should be 0/low when shutdown
<naobsd>
otherwise pressing power button doesn't work after shutdown
<naobsd>
but I have no idea how should I configure it
<naobsd>
I think regulator-fixed cannot become "system-power-controller"
<naobsd>
I need something like syscon-poweroff for gpio
<sjoerd>
naobsd: fwiw i never understood why there is both a gpio properity in regulator-fixed and a seperate regulator-gpio
<sjoerd>
historic reasons i guess
<mmind00>
naobsd: btw. according to my R88 schematics, gpio0-a3 seems to be the OTP-out
<mmind00>
sjoerd: if you mean gpio-regulator that is actually for regulators supporting multiple voltages via gpio-settings
<naobsd>
sjoerd: I'm not sure too but it seems regulator-gpio can have "GPIO group"
<sjoerd>
mmind00: that part is optional though
<naobsd>
mmind00: then rk3368.dtsi should be fixed :)
<sjoerd>
mmind00: A gpio-regularotr with just an enable gpio is entirely valid according to the binding :)
<naobsd>
btw I tried to toggle gpio0-3 on my board and nothing happened, probably it's N/C on my board
<naobsd>
I noticed mmc cd pin can be exported as gpio, strange
* mmind00
gets nostalgic when scrolling through the gpio-regulator history :-)

hmm, testing ir receiver and bluetooth consume some time :(
<naobsd>
it needs some userland...
<naobsd>
btw
<naobsd>
there is RK3168 TRM on rockchip.fr
<naobsd>
I have a RK3168 board with UART2 TP... I want to try some thing...

I have RK2926 and RK3026 tablets too, but these SoCs doesn't have UART2 pins. only OTg pass-thru is available...
<naobsd>
I should check SD boot on these SoCs
<naobsd>
I have no idea how many people have interest for these older SoCs
<naobsd>
probably it will be better to try recent Cortex-A7 based devices ;)
