#<Daulity> is there a kernel option to not reset gpio state at linux boot ? #<zmatt> Daulity: the kernel does not reset any gpio unless explicitly requested to by a driver #<zmatt> though by default if cape-universal is enabled then a gpio-of-helper device gets set up which configures all gpios as input... though that is normally the state they are in anyway after reset #<zmatt> Daulity: why? are you setting gpios in u-boot? #<Daulity> yes u-boot sets a few gpio's before it boots the kernel they get reset to a certain state not certain if u-boot or linux kernel #<Daulity> was just wondering #<zmatt> the annoying bit is that this isn't really fixable by applying an overlay on top of cape-universal due the the limitations of overlays and the fact that status="disabled"; doesn't work on individual gpios of a gpio-of-helper device node #<zmatt> so your options are to modify the cape-universal overlay or disable cape-universal entirely and use an overlay to declare/export gpios (with initialization of your choice) #<Daulity> i see #<zmatt> (or fix the gpio-of-helper drivers to respect the status property of individual gpios... which is probably a 2-line patch) #<zmatt> *driver #<zmatt> interesting, if CONFIG_OF_KOBJ=n then nodes with non-okay status property don't even get deserialized, however in practice CONFIG_OF_KOBJ is always y (specifically, it is only n in kernels that lack sysfs support) #<zmatt> yeah it's definitely a 2-line fix #<zmatt> https://pastebin.com/f8V8pz1V #<Daulity> thanks :) #<zmatt> rcn-ee: can you include that patch? that way overlays can disable cape-universal's gpio export for individual gpios used by the overlay #<zmatt> e.g. &ocp { cape-universal { P9_14 { status = "disabled"; }; }; }; #<zmatt> Daulity: you can use that in an overlay and then if you still want the gpio exported you can just declare your own gpio-of-helper ... unfortunately it doesn't support exporting a gpio without initializing it, but at least you can choose *how* to initialize it (input, output-low, output-high) and whether or not linux userspace is allowed to change the direction of the gpio Signed-off-by:

------=_Part_422_1349561576.1515022447432 Content-Type: text/plain; charset="UTF-8" Hello all, The TI touch screen driver does not work _right_ with the libts-bin package in the jessie image. $ cat /etc/dogtag BeagleBoard.org Debian Image 2018-01-01 $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 8.10 (jessie) Release: 8.10 Codename: jessie $ dpkg -l | grep libts-bin ii libts-bin 1.14-1rcnee0~jessie+20171122 armhf touch screen library utilities $ sudo ts_calibrate ts_setup: No such file or directory It is possible to make it work by setting the TSLIB_TSDEVICE environment variable: $ sudo su # export TSLIB_TSDEVICE=/dev/input/event2 # ts_calibrate But, that's a bit of a pain since the environment variable always needs to be set in order to use the touchscreen. It appears that this version of the utilities uses the INPUT_PROP_DIRECT propbit to automatically detect which /dev/input/event device is the touchscreen. It looks like the following is the only change needed to make it work. Unfortunately, I don't have currently have a way to build a custom kernel for the BeagleBone in order to test it. If there is anyone that could I would appreciate it. Regards, Hartley -

The adcxx4s communicates with a host processor via an SPI/Microwire Bus interface. The device family responds with 12bit data, of which the LSB bits are transmitted by the lower resolution devices as 0. We don't need to mess with ADC108S102_BITS as a result for the lower resolution devices. I have been able to test adc102s051, hence adding just the missing ones in that family. Lets reuse the driver to support the family of devices with name ADC<bb><c>S<sss>, where * bb is the resolution in number of bits (8, 10, 12) * c is the number of channels (1, 2, 4, 8) * sss is the maximum conversion speed (021 for 200 kSPS, 051 for 500 kSPS and 101 for 1 MSPS) Complete datasheets are available at TI's website here: https://www.ti.com/lit/gpn/adc<bb><c>s<sss>.pdf Also see: drivers/hwmon/adcxx.c Link: https://lore.kernel.org/linux-iio/20220701042919.18180-3-nm@ti.com/ Signed-off-by:
