Some Observations on Pine64+ 5.43.180428

Not sure if this has been reported - the usual way of enabling spi overaly "overlays=spi-spidev  and param_spidev_spi_bus=x" seems to be broken and when an overlay fails at boot time, it tries to load the base dtb from /.../alllwinner/allwinner/*,  note the extra allwinner in the path - so it fails. The pin definitions for the Euler SPI are wrong. When you manage to get both SPIs up. SPI 0 is being enabled as spi1.0 and SPI 1 being enabled as spi0.0. It also fails to merge board neutral ili9341 SPI definition files (at boot time) that has always worked on H3 and H5 boards.

To work around for now, use the following ( spi0.dts,  spi1.dts) to get the spidev's up - not sure why these worked and spi-spidev didn't (is it because of the parameter requiring fix-ups?). Also note they enable the wrong spi. After they are added, SPIs are working as you can use notro's fbtft (via modprobe) on them but not both at the same time.

Cannot readily use 5.44 yet as the kernel headers are missing. 

 I understand SPI is not in the matrix until 4.15 - how to report these issues so they can be fixed soon?
