* i2c: fix dangling comment in do_i2c_mw()Heiko Schocher2009-12-07-4/+0
| | | | | | | | commit bd3784df94bfeca43fbf34094df9cb1bd3ecca3b deleted some unused code in do_i2c_mw(), but missed to also remove the respective commment. This patch fixes this. Signed-off-by: Heiko Schocher <hs@denx.de>
* Removes dead code in the file common/cmd_i2c.cPratap Chandu2009-12-02-8/+0
| | | | | | | | There is some dead code enclosed by #if 0 .... #endif in the file common/cmd_i2c.c This patch removes the dead code. Signed-off-by: Pratap Chandu <pratap.rrke@gmail.com>
* cmd_i2c: bugfix: add missing braceAlessandro Rubini2009-07-18-3/+3
| | | | | | | | | | | The sub-command parser missed a brace, so "return 0;" is always taken and no error message is diplayed if you say "i2c scan" instead of "i2c probe", for example. Proper brace is added. Also, a misleading and unneeded else is removed. Signed-off-by: Alessandro Rubini <rubini@gnudd.com.it>
* General help message cleanupWolfgang Denk2009-06-12-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>
* cmd_i2c: Fix i2c help command output when CONFIG_I2C_MUXPeter Tyser2009-06-12-2/+2
| | | | | | | | | | | | | | | | | | | When CONFIG_I2C_MUX was defined the output of 'help i2c' was not correct, eg: => help i2c i2c bus [muxtype:muxaddr:muxchannel] - add a new bus reached over muxes. speed [speed] - show or set I2C bus speed i2c dev [dev] - show or set current I2C bus ... It has been changed to: i2c speed [speed] - show or set I2C bus speed i2c bus [muxtype:muxaddr:muxchannel] - add a new bus reached over muxes i2c dev [dev] - show or set current I2C bus ...

* i2c: Update references to individual i2c commandsPeter Tyser2009-06-12-16/+11
| | | | | | | | The individual i2c commands imd, imm, inm, imw, icrc32, iprobe, iloop, and isdram are no longer available so all references to them have been updated to the new form of "i2c <cmd>". Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* i2c: Remove deprecated individual i2c commandsPeter Tyser2009-06-12-58/+0
| | | | | | | | | | | | | The following individual I2C commands have been removed: imd, imm, inm, imw, icrc32, iprobe, iloop, isdram. The functionality of the individual commands is still available via the 'i2c' command. This change only has an impact on those boards which did not have CONFIG_I2C_CMD_TREE defined.

* i2c: Create common default i2c_[set|get]_bus_speed() functionsPeter Tyser2009-06-12-0/+18
| | | | | | | | | | | | | 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.

| | | | | | | | | | | If I2C Bus is blocked (see doc/I2C_Edge_Conditions), it is not possible to get out of this, until the complete Hardware gets a reset. This new commando calls again i2c_init (and that calls i2c_init_board if defined), which will deblock the I2C Bus. Signed-off-by: Heiko Schocher <hs@denx.de> Signed-off-by: Wolfgang Denk <wd@denx.de>

* Add support for multiple I2C busesBen Warren2006-11-03-5/+154
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
