[U-Boot] [PATCH v3 3/9] i2c, soft-i2c: switch to new multibus/multiadapter support
Heiko Schocher
hs at denx.de
Sat May 4 14:01:37 CEST 2013
- added to soft_i2c driver new multibus/multiadpater support
- adapted all config files, which uses this driver
Signed-off-by: Heiko Schocher <hs at denx.de>
Cc: Simon Glass <sjg at chromium.org>
Cc: Stephen Warren <swarren at wwwdotorg.org>
---
- changes for v2:
- fix EEprom_ivm setting for km82xx boards
- adapted README
- rebase against current mainline 178d0cc1a4c73c3341afbeb2a93b172de8c96bd1
- pass i2c_adapter struct to i2c_core callbacks
suggested by Stephen Warren and Simon Glass.
- changes for v3:
- adapt to the new introduced U_BOOT_I2C_ADAP_COMPLETE define
- added README entry
- patch has 2 different checkpatch warnings:
WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt
+# define I2C_SOFT_DECLARATIONS volatile ioport_t *iop = \
WARNING: Avoid CamelCase: <pFIO_DIR>
+#define I2C_INIT (*pFIO_DIR |= PF_SCL); asm("ssync;")
This should be fixed in a seperate step, as it affects a lot
of boards...
