| | | | | | | | | | | Let's clear the sr register before waiting for bit to be set, instead of clearing it after hardware sets it.

* mxs-i2c: Fix internal address byte orderTorsten Fleischer2012-07-11-1/+1
| | | | | | | | | | | | | | | | | | Large EEPROMs, e.g. 24lc32, need 2 byte to address the internal memory. These devices require that the high byte of the internal address has to be written first. The mxs_i2c driver currently writes the address' low byte first. The following patch fixes the byte order of the internal address that should be written to the I2C device.

* mxc_i2c: remove setting speed at each startTroy Kisky2012-07-11-6/+0
| | | | | | | | | | | | Other then being very weird, this code was also wrong. For example, say I set speed to 100K. I'll read back the speed as 85937. But the speed is really 85937.5, so we I reset the speed to 85937, I'll get 73660.7. After a couple of transactions my speed is now exactly 68750 so it will remain there.

* i2c: designware_i2c.c: Add support for the "i2c probe" commandStefan Roese2012-07-07-6/+10
| | | | | | | | | | | | | | | i2c_probe() is changed to reinit the i2c bus upon read failure. This is naturally the case upon i2c bus probing. Also, some printf messages upon read failure are removed. As they would interfere with the "i2c probe" command. Additionally, i2c_set_bus_speed() now returns 0, so that the "i2c speed" command can be used.

* Revert "I2C: OMAP: detect more devices when probing an i2c bus"Tom Rini2012-07-07-11/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 0e57968a215d1b9d271f3fa5bebeddeaea0c8075. The short version of the original commit is that some i2c devices cannot be probed via read as they NAK the first cycle, so try and probe via a write that we abort before it writes to the device. This however is not allowed by the TRM for any of these parts. The section on I2C_CON (table 17-35 I2C_CON for am/dm37x for example) says you must not change the register while STT has been set. On these parts, the unpredictable behavior that the chip exhibits is not problematic. On OMAP4 however it results in the chip being in a bad state: Panda # i2c probe Valid chip addresses: 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 3E 3F 40 41 42 43 44 45 46 47 48 49 4A 4B 4C 4D 4E 4F 50 51 52 53 54 55 56 57 58 59 5A 5B 5C 5D 5E 5F 60 61 62 63 64 65 66 67 68 69 6A 6B 6C 6D 6E 6F 70 71 72 73 74 75 76 77 78 79 7A 7B 7C 7D 7E 7F Panda # i2c md 50 0 timed out in wait_for_pin: I2C_STAT=0 I2C read: I/O error Error reading the chip.

* drivers/i2c/omap24xx_i2c.c: move all local variables to SRAMAndreas Müller2012-01-16-4/+9
| | | | | | | | | | | | | At old overo boards TWL4030 RTC irq is connected to gpio112. Unfortunately this pin is also used for revision detection. Therefore we need to send shut-up to TWL4030 to avoid reading wrong revision. In SPL this must be done before SDRAM is set up because the type of SDRAM is revision dependent. By this patch it is ensured that all variables used by omap24xx_i2c.c are located in SRAM.

| * I2C: Fix mxc_i2c.c problem on imx31_phycoreMarek Vasut2011-11-03-11/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem was caused by a global variable being used early in the boot process. The symptoms were on imx31_phycore board, reading the environment from I2C EEPROM didn't work correctly and causes default environment to be loaded.

* console: Squelch pre-console output in console functionsGraeme Russ2011-10-01-5/+1
| | | | | | | | | | There are some locations in the code which anticipate printf() being called before the console is ready by squelching printf() on gd->have_console. Move this squelching into printf(), vprintf(), puts() and putc(). Also make tstc() and getc() return 0 if console is not yet initialised Signed-off-by: Graeme Russ <graeme.russ@gmail.com> Tested-by: Simon Glass <sjg@chromium.org>
