[i2c] [patch 2.6.20-rc1 6/6] part II: update omap OSK support
David Brownell
david-b at pacbell.net
Tue Dec 19 00:29:15 CET 2006
Partial conversion of one board to use new style I2C driver binding:
- OMAP5912 OSK gets board info; it has from two to four I2C chips, depending
on whether the Mistral board is there, and whether a camera is attached.
- The tps65010 driver converts to "new style" driver binding, and moves some
of its board-specific init code out of the driver. (Unfortunately not all;
this driver is used during board bringup, and there's a shortage of places
to put such bringup code...)
This patch doesn't include changes to the AIC23 support (a complex ALSA driver
requiring some OMAP-specific interfaces, which has not yet gone upstream), the
ov9640 driver (similar, but it's a camera driver instead), or the at24c driver.
Most of the tps65010 changes (by volume) are just adjusting to the fact that
this driver no longer allocates the i2c_client structure. But it's also
about 10% smaller, mostly because the I2C_CLIENT_INSMOD data is gone.
