[PATCH v2 0/1] arm64: dts: renesas: r9a09g047e57-smarc: Enable I3C
Posted by Tommaso Merciai 1 week, 4 days ago
Dear all,

This patch enable I3C support to the rzg3e-smarc-som.dtsi.
Tested using NXP P3T1085UK-ARD connected to the RZ/G3E SMARC SoM
via the RZ/G3E SMARC BREAKOUT board.

Using the following connections:

 RZ SMARC Carrier II (CN1)  →  RZ SMARC BREAKOUT board
 +--------------------------------------------------------+

 RZ SMARC Carrier II (PMOD1_6)  →  P3T1085UK-ARD (J9)
 +--------------------------------------------------------+
 |    PWR_PMOD1  (pin 6)    →    (pin 9)   +3V3           |
 |    GND        (pin 5)    →    (pin 7)   GND            |
 +--------------------------------------------------------+

 RZ SMARC BREAKOUT board (CN1)  →  P3T1085UK-ARD (J13)
 +--------------------------------------------------------+
 |    GND      (pin 2)    →    (pin 4)   GND              |
 |    I3C_SCL  (pin 3)    →    (pin 1)   SCL_I3C          |
 |    I3C_SDA  (pin 4)    →    (pin 2)   SDA_I3C          |
 +--------------------------------------------------------+

 The following jumpers setup is required on the P3T1085UK-ARD board:
 - JP1: 1-2
 - JP2: 1-2
 - JP3: 1-2

 The following SW1(1,2) switch setup is required on the RZ SMARC BREAKOUT
 board:
 - SW1(1): 1
 - SW1(2): 1

Thanks & Regards,
Tommaso

v1->v2:
 - Dropped overlay and moved I3C support (pure bus mode) directly to the
   rzg3e-smarc-som.dtsi as suggested by Wolfram Sang.
 - Removed alias as suggested by Wolfram Sang.
