On Vybrid, the machine/architecture specific code seems not to
enable wakeup for devices, hence force RTC as wakeup source in
the driver.

The smbus block read is not currently supported for imx i2c devices.
This patchset adds the support to imx i2c bus so that blocks of data
can be read using SMbus block reads.(using i2c_smbus_read_block_data()
function from the i2c_core.c.). Tested with 3.10.9 kernel.

Adding the i2c_add_numbered_adapter might already lead to calls
of i2c_imx_xfer, which requires the semaphore to be assigned.
Hence we should assign the semaphore before add the I2C adapter.

Don't disable I2C clock between each transfers. Instead, disable the
module internally between the transfers. This also fixes SMBus
multi-block transfers.

    0d1862e can: flexcan: fix flexcan_chip_start() on imx6

the loop in flexcan_chip_start() that iterates over all mailboxes after the
soft reset of the CAN core was removed. This loop put all mailboxes (even the
ones marked as reserved 1...7) into EMPTY/INACTIVE mode. On mailboxes 8...63,
this aborts any pending TX messages.

After a cold boot there is random garbage in the mailboxes, which leads to
spontaneous transmit of CAN frames during first activation. Further if the
interface was disabled with a pending message (usually due to an error
condition on the CAN bus), this message is retransmitted after enabling the
interface again.

This patch fixes the regression by:
1) Limiting the maximum number of used mailboxes to 8, 0...7 are used by the RX
FIFO, 8 is used by TX.
2) Marking the TX mailbox as EMPTY/INACTIVE, so that any pending TX of that
mailbox is aborted.

Add parameter to define the minimal pressure required to be interpreted
as a touch event. Also filter out unusual high pressure since this
means there is no touch screen connected.

Extend FlexCAN driver to support Vybrid. Vybrids variant of the IP
has ECC support which is controlled through the memory error
control register (MECR). There is also an errata which leads to
false positive error detections (ID e5295). This patch disables
the memory error detection completely.

Extend the clock control for FlexCAN to enable the clocks.

Fix the base addresses and introduce the necessary pinmux defines.

In flexcan_chip_enable() and flexcan_chip_disable() fixed delays are used.
Experiments have shown that the transition from and to low power mode may take
several microseconds.

This patch adds a while loop which polls the Low Power Mode ACK bit (LPM_ACK)
that indicates a successfull mode change. If the function runs into a timeout a
error value is returned.

This is a simpliefied backport of
