i2c:soft:multi: Support for multiple soft I2C buses at Samsung boards

2012-09-17T07:39:50+00:00

Support for multiple soft I2C buses.

Multibus I2C support is achieved by defining get_multi_{sda|scl}_pin
functions to switch between multiple "soft" I2C buses.

Common definition of I2C_X I2C buses is provided at .

TEST HW:
     Samsung's Exynos4210 evt.0.1 - Trats development board

fix: error ATMEL_FIO_BASE undeclared, if use I2C_Soft on AT91

2012-01-11T07:03:46+00:00

* Since AT91 name schema was changed to ATMEL_BASE_xxx, I2C_SOFT
  on AT91 devices fails with 'error: ATMEL_FIO_BASE undeclared'
* change ATMEL_PIO_BASE to ATMEL_BASE_PIOA will fix this

Revert "GCC4.6: Convert various empty macros to inline functions"

2011-10-04T19:19:19+00:00

This reverts commit 60ce53cf9f408d9ad721f8e7a87d6a564e6d5bac.

The commit causes build breakage for a number of boards. This results
from the fact that now the arguments of debug() actually get
referenced (even if there is hope that the compiler will optimize
away the debug() call).  The obvious fix to that probem (change the
code to always declare the referenced variables and data structures)
increases the code size, and was this rejected.  So it was decided to
revert this commit until a better solution is found.

i2c: add i2c deblock sequence before and after every mux config

2011-04-28T08:56:54+00:00

To make sure that the mux can be configured a deblocking sequence
is done before the mux configuration. After the mux switch the new leaf
of, the i2c tree must be again deblocked.

fsl_i2c: Added a callpoint for i2c_board_late_init

2010-04-19T05:46:35+00:00

This patch adds a callpoint in i2c_init that allows board specific
i2c board initialization (typically for i2c bus reset) that is called
after i2c_init operations, allowing the i2c_board_late_init function
to use the pre-configured i2c bus speed and slave address.

i2c: made unused function i2c_mux_add_device static

2010-03-29T11:29:12+00:00

and removed it from the .h file

powerpc: updates for the keymile boards

2009-07-20T22:06:11+00:00

- CONFIG_SYS_MAX_I2C_BUS changed to 1
  We use only one I2C hardwarecontroller on this boards, so
  change the CONFIG_SYS_MAX_I2C_BUS to 1.
- common: dont print errormsg if second IVM Block lacks.
- 82xx, mgcoge: fix double mtdpart entry in environment
- 82xx, mgcoge: activate on second Flash the second bank.
- common: CONFIG_ENV_SIZE 0x4000 for all keymile boards
- common: Change malloc size to 1MByte for all Keymile boards
    We need a bigger malloc area for the environment support (128k)
    on some Keymile boards (kmeter1) and the upcoming UBI support.
    Change it to 1MB for all Keymile boards to be on the save side.
    Also define CONFIG_SYS_64BIT_VSPRINTF which is needed for
    UBI/UBIFS support.
- Add UBI support to all Keymile boards
- change manner of writing "/localbus/ranges" node
    instead of writting the complete "/localbus/ranges" node
    before booting Linux, only update the ranges entries
    which gets dynamical detected (size of flashes).
    This is needed, because keymile adds in the DTS
    "/localbus/ranges" node entries, which u-boot must
    not overwrite/delete.
- kmeter, mgcoge: define 2 seperate regions needed for the Intel P30 chips
    The Intel P30 chip has 2 non-identical chips on
    one die, so we need to define 2 seperate regions
    that are scanned by physmap_of independantly.
- kmeter1: Add MTD concat support to Keymile boards
- 82xx, mgcoge: add "unlock=yes" to default environment
- added CONFIG_MTD_DEVICE to get in sync with mainline code
