Subject: [PATCH 00/15] MIPS: pistachio: Creator Ci40 aka Marduk SPI-UART

Hello,

This patchset enables SPI and UARTs for the Ci40's mikroBUS and Raspberry Pi B+
connectors, as well as the remaining seven LEDs and as dependency the 802.15.4.

I also dug out some related driver fixes from their pistachio-4.9-lede branch:
https://github.com/CreatorDev/linux/commits/pistachio-4.9-lede

Tested with a LoRa click expansion board. [*]
Note that a number of drivers are missing in the pistachio defconfig. This
should probably be remedied as follow-up.

While all creatordev.io websites appear to be gone, I still had a local copy
of the Ci40 schematics document.

This patchset: https://github.com/afaerber/linux/commits/ci40-spi-uart.v1

Some more potential patches for missing features appear to be here:
https://github.com/CreatorDev/linux/commits/pistachio-4.9-wip

Have a lot of fun!

Cheers,
Andreas

P.S. As follow-up to this series I've reported on linux-serial that sc16is7xx
and serdev drivers don't appear to play nicely together:
