Stefan Wahren (2): pinctrl: bcm2835: Implement bcm2835_pinconf_get pinctrl: bcm2835: Implement bcm2711_pinconf_getI don't see any problems with this, can I just apply the patches or do you want to first resend them as non-RFC?since the second patch hasn't been tested with BCM7211, it would be nice to get a feedback from Florian or someone else with this hardware?Give me a few days to get there and I will run a test.is there any chance to test with BCM7211?
Sorry about the delay, I just gave those patches a try although I am not sure where I should be seeing the reporting about being configured as pull up/down? Is this supposed to be visible under /sys/kernel/debug/pinctrl/*.gpio-pinctrl-bcm2711/pins?
Checking the datasheet for 2711/7211 we advertise 50kOhms internal pull ups/downs for all GPIO pins, so we might need to make the resistor value different based upon the board/SoC maybe.
