Also remove the suspend function since all it does is log.

Now that we have defined generic set_bit_le() we do not need to use
test_and_set_bit_le() for atomically setting a bit.

Hi Richard,
I am new to serial framework. Can you please elaborate on what you
mean by implementing a hangup ?

Some 85xx silicons like MPC8536 and P1022 have a JOG feature, which provides
a dynamic mechanism to lower or raise the CPU core clock at runtime.
This patch adds the support to change CPU frequency using the standard
cpufreq interface. The ratio CORE to CCB can be 1:1(except MPC8536), 3:2,
2:1, 5:
The cpufreq driver of mpc85xx will disable/enable cpu hotplug temporarily.
Therefore, the related functions should be exported.

Thanks !
IMO, goto statements are meaningful on _probe().
However, 'goto err_sysfs' also can be removed if the size of code is critical.

I don't know if it is just me, but a code snippet might help

Without checking if the auart supports the hardware flow control or not,
the old mxs_auart_set_mctrl() asserted the RTS pin blindly.
This will causes the auart receives wrong data in the following case:
The far-end has already started the write operation, and wait for

Hi,
I have written a console driver where I also do the serial driver
registration and handling. The driver seems to work fine till the
login point(reads and writes). The driver for some reason does not
print the content I type on console after login prompt. Any reason
why this might be happening

Speaking of old "parches" lying about, the below fixes a real problem if
you're using either 'should die' isolcpus or 'should work' cpusets to
isolate cores.
