i2c: mxs: only flag completion when queue is completely done

2012-02-24T21:28:27+00:00

The hardware generates an interrupt for every completed command in the
queue while the code assumed that it will only generate one interrupt
when the queue is empty. So, explicitly check if the queue is really
empty. This patch fixed problems which occurred due to high traffic on
the bus. While we are here, move the completion-initialization after the
parameter error checking.

i2c: OMAP: Fix OMAP1 build error

2012-01-20T16:24:22+00:00

CONFIG_OF is not defined for OMAP1 yet and thus the omap1_defconfig build
generate an error for 3.3-rc1.

drivers/i2c/busses/i2c-omap.c: In function 'omap_i2c_probe':
drivers/i2c/busses/i2c-omap.c:1021:26: error: 'omap_i2c_of_match' undeclared (first use in this function)
drivers/i2c/busses/i2c-omap.c:1021:26: note: each undeclared identifier is reported only once for each function it appears in

Wrap omap_i2c_of_match with of_match_ptr() to prevent compilation error in case of OMAP1 build.

i2c-eg20t: use i2c_add_numbered_adapter to get a fixed bus number

2012-01-17T23:24:37+00:00

For EG20T and ML7213 IOH, the i2c controller numbers are fixed, using
fixed bus number will make it much easier for platform code to use
i2c_register_board_info() to register i2c devices.
