i2c-tegra: fix possible race condition after tx

2011-09-06T23:13:40+00:00

In tegra_i2c_fill_tx_fifo, once we have finished pushing all the bytes to the I2C hardware controller, the interrupt might happen before we have updated i2c_dev->msg_buf_remaining at the end of the function. Then, in tegra_i2c_isr, we will call again tegra_i2c_fill_tx_fifo triggering weird behaviour. This has been shown to happen under real conditions.

i2c-tegra: Add of_match_table

2011-09-06T23:11:46+00:00

This patch was intended to be part of 7ca2d1a105a239e300b937e9c41a10a4bd08f569 "i2c: Tegra: Add DeviceTree support". However, an early version of that patch, which was missing a chunk, was applied to next-i2c. This change is that missing chunk.

Revert "i2c-omap: fix static suspend vs. runtime suspend"

2011-08-23T19:19:16+00:00

This reverts commit adf6e07922255937c8bfeea777d19502b4c9a2be. Remove system PM methods which can race with runtime PM methods. Also, as of v3.1, the PM domain level code for OMAP handles device power state transistions automatically for devices, so drivers no longer need to specifically call the bus/pm_domain methods themselves.

i2c-nomadik: Do not use _interruptible_ variant call

2011-08-23T19:13:39+00:00

If there is a signal pending and wait_for_completion_interruptible_timeout exited because of the -ERESTARTSYS error we are unable to send any more i2c messages. So, deprecate this _interruptible_ variant call. Signed-off-by: Srinidhi Kasagar Signed-off-by: Linus Walleij Signed-off-by: Ben Dooks

i2c-eg20t : Fix the issue of Combined R/W transfer mode

2011-07-26T23:02:28+00:00

issue-1 In case combined transfer mode fails halfway, the processing must be stopped halfway. However currently, the processing is continued. This patch breaks the processing. issue-2 Currently, pch_i2c_xfer returns read/write size at that time. However pch_i2c_xfer must return the number of messages to be read/written. This patch modifies correctly. Signed-off-by: Tomoya MORINAGA Signed-off-by: Ben Dooks

i2c-eg20t : Support Combined R/W transfer mode
