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: https://marc.info/?l=linux-serial&m=153228314300681&w=2 [*] Cf. netdev https://patchwork.ozlabs.org/cover/937545/ Cc: Rob Herring <robh@xxxxxxxxxx> Cc: devicetree@xxxxxxxxxxxxxxx Cc: Mark Brown <broonie@xxxxxxxxxx> Cc: linux-spi@xxxxxxxxxxxxxxx Cc: Vinod Koul <vkoul@xxxxxxxxxx> Cc: dmaengine@xxxxxxxxxxxxxxx Cc: Michael Turquette <mturquette@xxxxxxxxxxxx> Cc: Stephen Boyd <sboyd@xxxxxxxxxx> Cc: linux-clk@xxxxxxxxxxxxxxx Andreas Färber (7): MIPS: dts: img: pistachio_marduk: Reorder nodes MIPS: dts: img: pistachio_marduk: Cleanups MIPS: dts: img: pistachio: Rename spim0-clk pin node label MIPS: dts: img: pistachio_marduk: Enable SPIM0 MIPS: dts: img: pistachio_marduk: Add 6Lowpan node MIPS: dts: img: pistachio_marduk: Add SPI UART node MIPS: dts: img: pistachio_marduk: Add user LEDs Damien Horsley (1): dmaengine: img-mdc: Handle early status read Govindraj Raja (1): clk: pistachio: Fix wrong SDHost card speed Ian Pozella (1): MIPS: dts: img: pistachio_marduk: Switch mmc to 1 bit mode Ionela Voinescu (5): spi: img-spfi: Implement dual and quad mode spi: img-spfi: Set device select bits for SPFI port state spi: img-spfi: Use device 0 configuration for all devices spi: img-spfi: RX maximum burst size for DMA is 8 spi: img-spfi: Finish every transfer cleanly arch/mips/boot/dts/img/pistachio.dtsi | 2 +- arch/mips/boot/dts/img/pistachio_marduk.dts | 174 ++++++++++++++++++++++------ drivers/clk/pistachio/clk-pistachio.c | 3 +- drivers/dma/img-mdc-dma.c | 40 ++++--- drivers/spi/spi-img-spfi.c | 165 +++++++++++++++++++++----- include/dt-bindings/clock/pistachio-clk.h | 1 + 6 files changed, 299 insertions(+), 86 deletions(-) -- 2.16.4
