i2c: pnx: Disable clk in suspend

2012-05-07T15:53:37+00:00

commit 6c557cfee08751d22aed34840f389b846f0f4508 upstream.

In the driver's suspend function, clk_enable() was used instead of
clk_disable(). This is corrected with this patch.

i2c-algo-bit: Fix spurious SCL timeouts under heavy load

2012-03-15T17:11:05+00:00

When the system is under heavy load, there can be a significant delay
between the getscl() and time_after() calls inside sclhi(). That delay
may cause the time_after() check to trigger after SCL has gone high,
causing sclhi() to return -ETIMEDOUT.

To fix the problem, double check that SCL is still low after the
timeout has been reached, before deciding to return -ETIMEDOUT.

Fix that. Also convert this and the related comment to proper commenting
style.

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.
