* i2c.h: Provide a default CONFIG_SYS_I2C_SLAVE valuePeter Tyser2009-06-12-3/+9
| | | | | | | | Many boards/controllers/drivers don't support an I2C slave interface, however CONFIG_SYS_I2C_SLAVE is used in common code so provide a default Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* i2c.h: drop i2c_reg_{read, write} hack for Blackfin partsMike Frysinger2009-02-12-14/+0
| | | | | | | The Blackfin i2c driver has been rewritten thus the special ifdefs in the common code are no longer needed. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* i2c: merge all i2c_reg_read() and i2c_reg_write() into inline functionsTimur Tabi2008-12-15-2/+60
| | | | | | | | | | 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.

* I2C: adding new "i2c bus" Command to the I2C Subsystem.Heiko Schocher2008-10-18-0/+23
| | | | | | | With this Command it is possible to add new I2C Busses, which are behind 1 .. n I2C Muxes. Details see README. Signed-off-by: Heiko Schocher <hs@denx.de>
* soft_i2c: prevent compiler warnings if driver does not use CPU Pins.Heiko Schocher2008-10-18-0/+9
| | | | | | | | | | | | | | | | | | | | | This patch fixes the following warnings, when using the soft_i2c driver using no CPU pins on MPC82xx or MPC8xx systems: soft_i2c.c: In function 'send_reset': soft_i2c.c:93: warning: unused variable 'immr' soft_i2c.c: In function 'send_start': soft_i2c.c:124: warning: unused variable 'immr' soft_i2c.c: In function 'send_stop': soft_i2c.c:146: warning: unused variable 'immr' soft_i2c.c: In function 'send_ack': soft_i2c.c:171: warning: unused variable 'immr' soft_i2c.c: In function 'write_byte': soft_i2c.c:196: warning: unused variable 'immr' soft_i2c.c: In function 'read_byte': soft_i2c.c:244: warning: unused variable 'immr' Signed-off-by: Heiko Schocher <hs@denx.de>
* Big white-space cleanup.Wolfgang Denk2008-05-21-4/+4
| | | | | | | | | | | 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. Signed-off-by: Wolfgang Denk <wd@denx.de>

* [PATCH] PPC4xx: Add support for multiple I2C bussesStefan Roese2007-02-20-0/+10
| | | | | | | | | | | | | | This patch adds support for multiple I2C busses on the PPC4xx platforms. Define CONFIG_I2C_MULTI_BUS in the board config file to make use of this feature. It also merges the 405 and 440 i2c header files into one common file 4xx_i2c.h. Also the 4xx i2c reset procedure is reworked since I experienced some problems with the first access on the 440SPe Katmai board. Signed-off-by: Stefan Roese <sr@denx.de>

* Add support for multiple I2C busesBen Warren2006-11-03-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hello, Attached is a patch providing support for multiple I2C buses at the command level. The second part of the patch includes an implementation for the MPC834x CPU and MPC8349EMDS board. /*** Note: This patch replaces ticket DNX#2006083042000018 ***/ Signed-off-by: Ben Warren <bwarren@qstreams.com> Overview: 1. Include new 'i2c' command (based on USB implementation) using CONFIG_I2C_CMD_TREE. 2. Allow multiple buses by defining CONFIG_I2C_MULTI_BUS. Note that the commands to change bus number and speed are only available under the new 'i2c' command mentioned in the first bullet. 3. The option CFG_I2C_NOPROBES has been expanded to work in multi-bus systems. When CONFIG_I2C_MULTI_BUS is used, this option takes the form of an array of bus-device pairs. Otherwise, it is an array of uchar. CHANGELOG: Added new 'i2c' master command for all I2C interaction. This is conditionally compiled with CONFIG_I2C_CMD_TREE. New commands added for setting I2C bus speed as well as changing the active bus if the board has more than one (conditionally compiled with CONFIG_I2C_MULTI_BUS). Updated NOPROBE logic to handle multiple buses. Updated README. regards, Ben

Requires new CPLD code (Version 101 for Rev. 100 boards, version 153 for Rev. 200 boards). * Patch by Vladimir Gurevich, 12 Mar 2003: Fix relocation problem of statically initialized string pointers in common/cmd_pci.c * Patch by Kai-Uwe Blöm, 12 Mar 2003: Cleanup & bug fixes for JFFS2 code: - the memory mangement was broken. It caused havoc on malloc by writing beyond the block boundaries. - the length calculation for files was wrong, sometimes resulting in short file reads. - data copying now optionally takes fragment version numbers into account, to avoid copying from older data. See doc/README.JFFS2 for details.
