|

If you do not have i2c muxes on your board, omit this define.
|
||||
|
||||
- Legacy I2C Support: CONFIG_HARD_I2C
|
||||
|
||||
NOTE: It is intended to move drivers to CONFIG_SYS_I2C which
|
||||
provides the following compelling advantages:
|
||||
|
||||
- more than one i2c adapter is usable
|
||||
- approved multibus support
|
||||
- better i2c mux support
|
||||
|
||||
** Please consider updating your I2C driver now. **
|
||||
|
||||
These enable legacy I2C serial bus commands. Defining
|
||||
CONFIG_HARD_I2C will include the appropriate I2C driver
|
||||
for the selected CPU.
|
||||
|
||||
This will allow you to use i2c commands at the u-boot
|
||||
command line (as long as you set CONFIG_CMD_I2C in
|
||||
CONFIG_COMMANDS) and communicate with i2c based realtime
|
||||
clock chips. See common/cmd_i2c.c for a description of the
|
||||
command line interface.
|
||||
|
||||
CONFIG_HARD_I2C selects a hardware I2C controller.
|
||||
|
||||
There are several other quantities that must also be
|
||||
defined when you define CONFIG_HARD_I2C.
|
||||
|
||||
In both cases you will need to define CONFIG_SYS_I2C_SPEED
|
||||
to be the frequency (in Hz) at which you wish your i2c bus
|
||||
to run and CONFIG_SYS_I2C_SLAVE to be the address of this node (ie
|
||||
the CPU's i2c node address).
|
||||
|
||||
Now, the u-boot i2c code for the mpc8xx
|
||||
(arch/powerpc/cpu/mpc8xx/i2c.c) sets the CPU up as a master node
|
||||
and so its address should therefore be cleared to 0 (See,
|
||||
eg, MPC823e User's Manual p.16-473). So, set
|
||||
CONFIG_SYS_I2C_SLAVE to 0.
|
||||
|
||||
CONFIG_SYS_I2C_INIT_MPC5XXX
|
||||
|
||||
When a board is reset during an i2c bus transfer
|
||||
chips might think that the current transfer is still
|
||||
in progress. Reset the slave devices by sending start
|
||||
commands until the slave device responds.
|
||||
|
||||
That's all that's required for CONFIG_HARD_I2C.
|
||||
|
||||
- Legacy I2C Support:
|
||||
If you use the software i2c interface (CONFIG_SYS_I2C_SOFT)
|
||||
then the following macros need to be defined (examples are
|
||||
from include/configs/lwmon.h):

CONFIG_SYS_I2C_BOARD_LATE_INIT
|

An alternative to CONFIG_SYS_I2C_INIT_BOARD. If this option is
|
||||
defined a custom i2c_board_late_init() routine in
|
||||
boards/xxx/board.c is run AFTER the operations in i2c_init()

is completed. This callpoint can be used to unreset i2c bus
|
||||
using CPU i2c controller register accesses for CPUs whose i2c
|
||||
controller provide such a method. It is called at the end of
|
||||
i2c_init() to allow i2c_init operations to setup the i2c bus
|

controller on the CPU (e.g. setting bus speed & slave address).

CONFIG_I2CFAST (PPC405GP|PPC405EP only)

This option enables configuration of bi_iic_fast[] flags
