Not sure if this does anything, but it is the 4.19 DTS. Signed-off-by: Patrick Menschel <[email protected]>
It gets hard to find something in here. Also add notes as guide to newbies. Signed-off-by: Patrick Menschel <[email protected]>

PRU_E_B is nowhere to be found in 4.14 dts file. How does it work? Signed-off-by: Patrick Menschel <[email protected]>
According to mailing list, this property actually pevents damage to devices and uboot is build without rtc-only support anyways. https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/commit/arch/arm/boot/dts/am335x-bone-common.dtsi?h=linux-5.10.y&id=7a6cb0abe1aa63334f3ded6d2b6c8eca80e72302 After some tests, the led_red is off when shutdown. Only remaining issue is that VDD_3V3AUX is still on after the device is supposed to have shutdown. This is also present with the previous state. Signed-off-by: Patrick Menschel <[email protected]>

Hello,
this is the second and hopefully last rework of the devicetree for the beaglebone blue.
I missed the pin for the PRU_E_A encoder. I have no clue what is done with the PRU_E_B pin. It apparently is not pinmux-able to pru and I don't see it in 4.14 dts file.
I added the motor_pwms according to what kernel docs say. I was looking at some adafruit lcd dts file for reference and then found the greatly hidden correct kernel documentation.
I fixed the wrongly copied pull-configurations for the pwm and eqep pins. It took a while to reverse engineer the hardcoded numbers.
I finally sorted the device tree in some pseudo alpha-numeric order. I was tired to always scroll through 4 pages just to find the right entry while comparing two files.
Finally the intended purpose to get the motors running was achieved and description was added to
forum discussion .
There is an urgent topic that needs to be discussed, the pmic-shutdown controller entry. I opened an issue for that.
