* arm64: dts: freescale: Rename DTB overlay source files from .dts to .dtsoAndrew Davis2022-11-191-61/+0
| | | | | | | | | | | | | DTB Overlays (.dtbo) can now be built from source files with the extension (.dtso). This makes it clear what is the content of the files and differentiates them from base DTB source files. Convert the DTB overlay source files in the arm64/freescale directory.

* arm64: dts: imx8mm-venice-gw73xx-0x: add dt overlays for serial modesTim Harvey2022-02-211-0/+61
The imx8mm-venice-gw73xx-0x som+baseboard combination has a multi-protocol RS-232/RS-485/RS-422 transceiver to an off-board connector which can be configured in a number of ways via UART and GPIO configuration. The default configuration per the imx8mm-venice-gw73xx-0x dts is for UART2 TX/RX and UART4 TX/RX to be available as RS-232: J15.1 UART2 TX out J15.2 UART2 RX in J15.3 UART4 TX out J15.4 UART4 RX in J15.5 GND Add dt overlays to allow additional the modes of operation: rs232-rts (UART2 RS-232 with RTS/CTS hardware flow control) J15.1 TX out J15.2 RX in J15.3 RTS out J15.4 CTS in J15.5 GND rs485 (UART2 RS-485 half duplex) J15.1 TXRX- J15.2 N/C J15.3 TXRX+ J15.4 N/C J15.5 GND rs422 (UART2 RS-422 full duplex) J15.1 TX- J15.2 RX+ J15.3 TX+ J15.4 RX- J15.5 GND Signed-off-by: Tim Harvey <tharvey@gateworks.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
