Add mikroBUS connector support for Beagleplay. Acts as a nexus node for gpios. Allows defining GPIOS relative to the connector. The pin numbering is as follows: 0: PWM 1: INT 2: RX 3: TX 4: SCL 5: SDA 6: MOSI 7: MISO 8: SCK 9: CS 10: RST 11: AN Signed-off-by: Ayush Singh <ayush@beagleboard.org> --- arch/arm64/boot/dts/ti/k3-am625-beagleplay.dts | 53 +++++++++++++++++++++++--- 1 file changed, 47 insertions(+), 6 deletions(-)
