054b62d9f2 i2c: imx: fix the i2c bus hang issue when do repeat restart
Test i2c device Maxim max44009, datasheet is located at:
http://www.maximintegrated.com/datasheet/index.mvp/id/7175

The max44009 support repeat operation like:
read -> repeat restart -> read/write

The current i2c imx host controller driver don't support this
operation that causes i2c bus hang due to "MTX" is cleared in
.i2c_imx_read(). If "read" is the last message there have no problem,
so the current driver supports all SMbus operation like:
write -> repeat restart -> read/write

IMX i2c controller for master receiver has some limitation:
- If it is the last byte for one operation, it must generate STOP
  signal before read I2DR to prevent controller from generating another
  clock cycle.
- If it is the last byte in the read, and then do repeat restart, it must
  set "MTX" before read I2DR to prevent controller from generating another
  extra clock cycle.

The patch is to fix the issue.

218e149613 i2c: exynos5: add support for HSI2C on Exynos5260 SoC
HSI2C module on Exynos5260 differs from current modules in
following ways:
1.  HSI2C on Exynos5260 has fifo_depth of 16bytes
2.  Module needs to be reset as a part of init sequence.

Hence, Following changes are involved.
1. Add a new compatible string and Updates the Documentation dt bindings.
2. Introduce a variant struct to support the changes in H/W
3. Reset the module during init. Thus, bringing the module back
to default state irrespective of what firmware did with it.

9219982bc6 i2c: nomadik: Fixup system suspend
For !CONFIG_PM_RUNTIME, the device were never put back into active
state while resuming.

For CONFIG_PM_RUNTIME, we blindly trusted the device to be inactive
while we were about to handle it at suspend late, which is just too
optimistic.

Even if the driver uses pm_runtime_put_sync() after each tranfer to
return it's runtime PM resources, there are no guarantees this will
actually mean the device will inactivated. The reason is that the PM
core will prevent runtime suspend during system suspend, and thus when
a transfer occurs during the early phases of system suspend the device
will be kept active after the transfer.

To handle both issues above, use pm_runtime_force_suspend|resume() from
the system suspend|resume callbacks.

b2e3432af1 Merge tag 'spi-v3.15-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi fixes from Mark Brown:
 "A few core fixes around outlying cases here, nothing that should
  affect most users but useful fixes.  The diffstat is rather larger
  than one might hope due some simple code motion in the fix for
  !CONFIG_DMA, the actual meaningful change is much smaller.

   - Fix handling of unsupported dual and quad mode support on slave
     registration so that drivers that can degrade gracefully do so,
     preventing regressions for drivers this is added.
   - Fix build in !CONFIG_DMA cases following addition of generic DMA
     mapping support.
   - Fix error handling for queue creation which due to wider kernel
     changes can be triggered more easily.
   - A couple of driver specific fixes"

  spi/pxa2xx: Prevent DMA from transferring too many bytes
