This functionality is part of the legacy I2C subsystem and is currently unused anywhere. Remove the remaining references.

This option specifies a list of I2C devices that will be skipped - when the 'i2c probe' command is issued. If CONFIG_I2C_MULTI_BUS - is set, specify a list of bus-device pairs. Otherwise, specify - a 1D array of device addresses + when the 'i2c probe' command is issued.
e.g. - #undef CONFIG_I2C_MULTI_BUS #define CFG_SYS_I2C_NOPROBES {0x50,0x68}
will skip addresses 0x50 and 0x68 on a board with one I2C bus
- #define CONFIG_I2C_MULTI_BUS - #define CFG_SYS_I2C_NOPROBES {{0,0x50},{0,0x68},{1,0x54}} - - will skip addresses 0x50 and 0x68 on bus 0 and address 0x54 on bus 1 - CFG_SYS_RTC_BUS_NUM
If defined, then this indicates the I2C bus number for the RTC. diff --git a/cmd/i2c.c b/cmd/i2c.c index da8b4c255555..f204061cf09f 100644 --- a/cmd/i2c.c +++ b/cmd/i2c.c @@ -98,7 +98,7 @@ static uint i2c_mm_last_alen; * pairs. The following macros take care of this */
