i2c: Move PPC4xx I2C driver into drivers/i2c directory

2010-04-06T06:10:41+00:00

This patch moves the PPC4xx specific I2C device driver into the I2C
drivers directory. All 4xx config headers are updated to include this
driver.

ppc4xx: Fix problem with I2C bus >= 1 initialization

2010-03-30T11:05:05+00:00

This patch fixes a problem introduced with patch eb5eb2b0
[ppc4xx: Cleanup PPC4xx I2C infrastructure]. We need to assign the I2C
base address to the "i2c" pointer inside of the controller loop.
Otherwise controller 0 is initialized multiple times instead of
initializing each I2C controller sequentially.

Tested on Katmai.

ppc4xx: Cleanup PPC4xx I2C infrastructure

2009-11-23T15:27:02+00:00

This patch cleans up the PPC4xx I2C intrastructure:

- Use C struct to describe the I2C registers instead of defines
- Coding style cleanup (braces, whitespace, comments, line length)
- Extract common code from i2c_read() and i2c_write()
- Remove unneeded IIC defines from ppc405.h & ppc440.h

i2c: Create common default i2c_[set|get]_bus_speed() functions

2009-06-12T18:39:45+00:00

New default, weak i2c_get_bus_speed() and i2c_set_bus_speed() functions
replace a number of architecture-specific implementations.

Also, providing default functions will allow all boards to enable
CONFIG_I2C_CMD_TREE.  This was previously not possible since the
tree-form of the i2c command provides the ability to display and modify
the i2c bus speed which requires i2c_[set|get]_bus_speed() to be
present.

i2c: merge all i2c_reg_read() and i2c_reg_write() into inline functions

2008-12-15T22:46:21+00:00

All implementations of the functions i2c_reg_read() and
i2c_reg_write() are identical. We can save space and simplify the
code by converting these functions into inlines and putting them in
i2c.h.

Big white-space cleanup.

2008-05-20T22:14:08+00:00

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

ppc4xx: Fix i2c divisor calcularion for PPC4xx

2007-04-12T12:15:59+00:00

This patch fixes changes the i2c_init(...) function to use the function
get_OPB_freq() rather than calculating the OPB speed by
sysInfo.freqPLB/sysInfo.pllOpbDiv. The get_OPB_freq() function is
specific per processor. The prior method was not and so was calculating
the wrong speed for some PPC4xx processors.
