From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx> Hi All, This series adds I3C node to RZ/V2N and RZ/V2H(P) SoC DTSI files. I3C was tested on RZ/V2H(P) and RZ/V2N EVKs using P3T1085UK Arduino Shield Evaluation Board [0]. Disable I2C2 on PMOD connector CN6 and enable I3C. Connect EVK TO P3T1085UK Arduino Shield Evaluation Board P3T1085UK <-> EVK PMOD CN6 - J13[1] to CN6[3] (I3C_SCL) - J13[2] to CN6[4] (I3C_SDA) - J13[4] to CN6[5] (GND) - J9[7] to CN6[11] (GND) - J9[9] to CN6[6] (3.3V) On P3T1085UK, - JP2 pin1 to pin2 (I3C_SDA) - JP3 pin1 to pin2 (I3C_SCL) - JP1 pin2 to pin3 (VDD 3V3) [0] https://www.nxp.com/design/design-center/development-boards-and-designs/analog-toolbox/arduino-shields-solutions/p3t1085uk-arduino-shield-evaluation-board:P3T1085UK-ARD Test Logs: --- RZ/V2H(P) --- root@rzv2h-evk:~# cat /sys/kernel/debug/clk/clk_summary | grep i3c i3c_0_pclk 1 2 0 100000000 0 0 50000 Y 12400000.i3c pclk i3c_0_pclkrw 1 2 0 100000000 0 0 50000 Y 12400000.i3c pclkrw i3c_0_tclk 1 2 0 200000000 0 0 50000 Y 12400000.i3c tclk root@rzv2h-evk:~# root@rzv2h-evk:~# cat /sys/class/hwmon/*/temp1_input 26687 26812 root@rzv2h-evk:~# cat /proc/interrupts | grep i3c 150: 38 0 0 0 GICv3 709 Edge i3c-resp 151: 2 0 0 0 GICv3 712 Edge i3c-rx 152: 0 0 0 0 GICv3 713 Edge i3c-tx 153: 0 0 0 0 GICv3 721 Level i3c-start 154: 0 0 0 0 GICv3 722 Level i3c-stop 155: 0 0 0 0 GICv3 724 Level i3c-tend 156: 0 0 0 0 GICv3 725 Level i3c-nack root@rzv2h-evk:~# cat /sys/class/hwmon/*/temp1_input 26687 26812 root@rzv2h-evk:~# cat /proc/interrupts | grep i3c 150: 42 0 0 0 GICv3 709 Edge i3c-resp 151: 2 0 0 0 GICv3 712 Edge i3c-rx 152: 0 0 0 0 GICv3 713 Edge i3c-tx 153: 0 0 0 0 GICv3 721 Level i3c-start 154: 0 0 0 0 GICv3 722 Level i3c-stop 155: 0 0 0 0 GICv3 724 Level i3c-tend 156: 0 0 0 0 GICv3 725 Level i3c-nack root@rzv2h-evk:~# --- RZ/V2N --- root@rzv2n-evk:~# cat /sys/kernel/debug/clk/clk_summary | grep i3c i3c_0_pclk 1 2 0 100000000 0 0 50000 Y 12400000.i3c pclk i3c_0_pclkrw 1 2 0 100000000 0 0 50000 Y 12400000.i3c pclkrw i3c_0_tclk 1 2 0 200000000 0 0 50000 Y 12400000.i3c tclk root@rzv2n-evk:~# cat /proc/interrupts | grep i3c 65: 22 0 0 0 GICv3 709 Edge i3c-resp 66: 2 0 0 0 GICv3 712 Edge i3c-rx 67: 0 0 0 0 GICv3 713 Edge i3c-tx 68: 0 0 0 0 GICv3 721 Level i3c-start 69: 0 0 0 0 GICv3 722 Level i3c-stop 70: 0 0 0 0 GICv3 724 Level i3c-tend 71: 0 0 0 0 GICv3 725 Level i3c-nack root@rzv2n-evk:~# cat /sys/class/hwmon/*/temp1_input 27000 27125 root@rzv2n-evk:~# cat /proc/interrupts | grep i3c 65: 26 0 0 0 GICv3 709 Edge i3c-resp 66: 2 0 0 0 GICv3 712 Edge i3c-rx 67: 0 0 0 0 GICv3 713 Edge i3c-tx 68: 0 0 0 0 GICv3 721 Level i3c-start 69: 0 0 0 0 GICv3 722 Level i3c-stop 70: 0 0 0 0 GICv3 724 Level i3c-tend 71: 0 0 0 0 GICv3 725 Level i3c-nack root@rzv2n-evk:~# Cheers, Prabhakar Lad Prabhakar (2): arm64: dts: renesas: r9a09g057: Add I3C node arm64: dts: renesas: r9a09g056: Add I3C node arch/arm64/boot/dts/renesas/r9a09g056.dtsi | 33 ++++++++++++++++++++++ arch/arm64/boot/dts/renesas/r9a09g057.dtsi | 33 ++++++++++++++++++++++ 2 files changed, 66 insertions(+) -- 2.51.0
