I've been through the expansion header pinouts trying to come up with a .dts configuration that enables a UART with hardware flow control (so TXD, RXD, CTS and RTS) but does NOT break any of i2c2, HDMI or the eMMC.
- uart0: Serial console, I need that already! (but it doesn't have RTS/CTS on J1) - uart1: RTS/CTS conflict with i2c2 (and RXD/TXD conflicts with i2c1!) - uart2: Has no hardware flow control pins exposed, conflicts with i2c2 - uart3: Is missing the RXD pin (and no h/w flow control!) - uart4: RTS/CTS conflict with HDMI - uart5: Conflicts with HDMI Am I right here? Is it not possible to do this? If it cannot be done, I guess I can live with out i2c -- there's a SPI version of what I need and SPI0 doesn't conflict with uart1. But I still have the following error due to the uart1_ctsn conflict with i2c2_sda; pinctrl-single 44e10800.pinmux: pin 44e10978 already requested by 4819c000.i2c; cannot claim for 48022000.serial Anyone know how to disable i2c2? [the cape mgr eeprom]? I'm not sure which wins here ... i2c2 or uart1.
