2013-08-27i2c: fix i2c dev command for not using new frameworkHeiko Schocher
i2c dev command does not work anymore for legacy drivers because a check is executed that is valid only in the new framework. Signed-off-by: Heiko Schocher <hs@denx.de> Tested-by: Stefano Babic <sbabic@denx.de>
2013-07-24Merge branch 'master' of git://git.denx.de/u-boot-i2cTom Rini
The sandburst-specific i2c drivers have been deleted, conflict was just over the SPDX conversion. Conflicts: board/sandburst/common/ppc440gx_i2c.c board/sandburst/common/ppc440gx_i2c.h Signed-off-by: Tom Rini <trini@ti.com>

2013-07-23i2c, multibus: get rid of CONFIG_I2C_MUXHeiko Schocher
CONFIG_I2C_MUX is replaced through the new i2c multibus/multiadapter framework, configured through CONFIG_SYS_I2C. As CONFIG_I2C_MUX is only used on the keymile boards, and they are now completely moved to the new framework, remove CONFIG_I2C_MUX.

2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk
The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

2009-07-18cmd_i2c: bugfix: add missing braceAlessandro Rubini
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>
2009-06-12General help message cleanupWolfgang Denk
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>
2009-06-12cmd_i2c: Fix i2c help command output when CONFIG_I2C_MUXPeter Tyser
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 ...

2009-06-12i2c: Update references to individual i2c commandsPeter Tyser
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>
2009-06-12i2c: Remove deprecated individual i2c commandsPeter Tyser
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. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2009-06-12i2c: Create common default i2c_[set|get]_bus_speed() functionsPeter Tyser
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.

2008-10-18I2C: add new command i2c reset.Heiko Schocher
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>
