i2c: Remove CONFIG_I2C_MULTI_BUS
This functionality is part of the legacy I2C subsystem and is currently unused anywhere. Remove the remaining references. Signed-off-by: Tom Rini <trini@konsulko.com>

@ -984,21 +984,13 @@ The following options need to be configured:
|
||||
CFG_SYS_I2C_NOPROBES
|
||||
|
||||
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.
