Hello Takashi,

Sorry for the late reply. I got pulled off on some other projects.

We will try to test this in-house but we will need Qualcomm's help.
I will also try to get some of our SOC partners to help with testing.

I think it will be difficult to complete the testing before that 5.2
deadline.
We should probably shoot for 5.3. If someone needs it sooner that they will
have the patches.

Thanks again for all this work.

I assume the four emails below have all the latest patches needed for rev 6.

Thanks,
Phil Burk
