struct timeval tv is used to get current time.
32-bit systems using 'struct timeval' will break in the year 2038, so
we have to replace that code with more appropriate types.

It's possible that multiple MAX732X can be hooked up to the same

MAX732X clears all pending interrupts on I2C read (when interrupts
register is being read). Driver doesn't need to send any ACKs when
interrupt was handled. So replace handle_edge_irq() with
handle_simple_irq().
Using handle_edge_irq() (w/o .irq_ack callback set) may lead to NULL

LKML is a very high volume list, if you're seeing problems that were
introduced by a particular patch, it's a good idea to CC the author of
that patch.
/me adds CC, and tags (again) to take a peek.

We may suffer from extra rt overload rq due to the affinity,
so when the affinity of any runnable rt task is changed, we
should check to trigger balancing, otherwise it will cause
some unnecessary delayed real-time response. Unfortunately,
current RT global scheduler does nothin

Hi All,
This patchset adds apq8016 audio support into lpass driver. Existing Lpass
driver can not be used as-it-is for apq8016 as it contains code specific to
ipq806x. Also the driver only supports single i2s port, single dma channel and
single bitclk control.
APQ8016 has 4 MI2S( Primary, Seconda
This patch remove redundant check after request_resource as ioremap would
do the check anyway.

This patch attempts to remove the hardcoded i2s port number in lpass
driver. Now the the port number comes from the dai id field.
This will allow other SOCs to use different port numbers on the lpass
driver.
