[PATCH 0/4] Add DT bindings and device tree for Compulab SB-UCM-iMX8MPLUS

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

This small patch series is a drive-by addition of the Compulab
SB-UCM-iMX8MPLUS to the Linux kernel device tree sources. While porting
the device tree from the Compulab BSP kernel to mainline, I thought I
could as well mainline it, along with related conversion of text DT
bindings to YAML.

The SB-UCM-iMX8MPLUS is a carrier board designed as a reference to
evaluate the Compulab UCM-iMX8MPLUS SoM. The SoM integrates the bare
minimal peripherals (DRAM, eMMC, ethernet PHY, EEPROM and RTC), while
the carrier board includes a much wider range of peripherals. I have
only enabled support for the ones I am interested in, or, as a strech
goal, the ones I could easily test.

The first patch in the series adds compatible strings for the SoM and
the board to the ARM FSL bindings. The next patch then converts text DT
bindings to a YAML schema for the RTC present on the SoM. Finally, the
last two patches add DT sources for the SoM and the carrier board.

Please see individual patches for details.

I have checked the validity of the bindings and the device tree sources.
The only warnings in the DT sources are due to issues in imx8mp.dtsi.
