Bus speeds of +100kHz (standard speed) and 400kHz (high speed I2C) are supported. + +Submitted-by: Birger Koblitz <git@birger-koblitz.de> +--- + drivers/i2c/busses/Kconfig | 10 +++++++++ + drivers/i2c/busses/Makefile | 1 + + 2 files changed, 11 insertions(+) + +--- a/drivers/i2c/busses/Kconfig ++++ b/drivers/i2c/busses/Kconfig +@@ -954,6 +954,16 @@ config I2C_RK3X + This driver can also be built as a module.
