u-boot.git/drivers/i2c, branch v2009.08-rc1 Unnamed repository; edit this file 'description' to name the repository. i2c, mpc83xx: add CONFIG_SYS_I2C_INIT_BOARD for fsl_i2c 2009-07-21T05:06:26+00:00 Heiko Schocher hs@denx.de 2009-07-09T10:04:26+00:00 39df00d9aecfb465b9eec9af593f9b763fb5209a This patch adds the possibility to call a board specific i2c bus reset routine for the fsl_i2c bus driver, and adds this option for the keymile kmeter1 board. The deblock sequence for this board is implemented and tested in the following way: CR = 0x20 (release SDA and SCL pin) CR = 0xa0 (start read) dummy read dummy read if 2. dummy read == 0x00 3. dummy read CR = 0x80 (SDA and SCL now 1 SR = 0x86) CR = 0x00 (Modul reset SR=0x81) CR = 0x80 (SDA and SCL = 1, SR = 0x81) Signed-off-by: Heiko Schocher <hs@denx.de> 
This patch adds the possibility to call a board specific
i2c bus reset routine for the fsl_i2c bus driver, and adds
this option for the keymile kmeter1 board.

The deblock sequence for this board is implemented and
tested in the following way:

CR = 0x20 (release SDA and SCL pin)
CR = 0xa0 (start read)
dummy read
dummy read
if 2. dummy read == 0x00
	3. dummy read

CR = 0x80 (SDA and SCL now 1 SR = 0x86)
CR = 0x00 (Modul reset SR=0x81)
CR = 0x80 (SDA and SCL = 1, SR = 0x81)

Blackfin: TWI/I2C: fix pure writes 2009-06-30T06:27:45+00:00 Peter Meerwald pmeerw@pmeerw.net 2009-06-29T19:48:33+00:00 98ab14e858bf60306d0aa3f0df5a7a5f88264aff If doing a pure write with register address and data (not a read/write combo transfer), we don't set the initial transfer length properly which ends up causing only the register address to be transferred. While we're here, fix the i2c_write() parameter description of the buffer. Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

i2c: Update references to individual i2c commands 2009-06-12T18:39:46+00:00 Peter Tyser ptyser@xes-inc.com 2009-04-19T03:34:03+00:00 0f89c54be92773b23d66ac401ba6acb6144100c3 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>".

i2c: Create common default i2c_[set|get]_bus_speed() functions 2009-06-12T18:39:45+00:00 Peter Tyser ptyser@xes-inc.com 2009-04-19T03:34:01+00:00 655b34a78adf60ef260981688837904208883ae9 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.
