The chosen -value doesn't determine the /dev/i2c-* value, but starting with -1 or 2 and counting upwards seems sensible. N.B. The bus parameter -has a default value of zero, so one instance doesn't need to specify -a value. - -Signed-off-by: Phil Elwell <phil@raspberrypi.org> ---- - arch/arm/boot/dts/overlays/README | 3 +++ - arch/arm/boot/dts/overlays/i2c-gpio-overlay.dts | 2 +- - 2 files changed, 4 insertions(+), 1 deletion(-) - ---- a/arch/arm/boot/dts/overlays/README -+++ b/arch/arm/boot/dts/overlays/README -@@ -693,6 +693,9 @@ Params: i2c_gpio_sda GPIO use - i2c_gpio_delay_us Clock delay in microseconds - (default "2" = ~100kHz) - -+ bus Set to a unique, non-zero value if wanting -+ multiple i2c-gpio busses (default "0") -+ - - Name: i2c-mux - Info: Adds support for a number of I2C bus multiplexers on i2c_arm ---- a/arch/arm/boot/dts/overlays/i2c-gpio-overlay.dts -+++ b/arch/arm/boot/dts/overlays/i2c-gpio-overlay.dts -@@ -38,6 +38,6 @@ - i2c_gpio_sda = <&i2c_gpio>,"gpios:4"; - i2c_gpio_scl = <&i2c_gpio>,"gpios:16"; - i2c_gpio_delay_us = <&i2c_gpio>,"i2c-gpio,delay-us:0"; -+ bus = <&i2c_gpio>, "reg:0"; - }; - }; -- |
