Cover letter [PATCH v2 0/3] ARM: imx: Add cpuidle for imx platforms
Quoted 26 lines · Sascha Hauer

Hi Robert,

Quoted 9 lines · Robert Lee

This patch series adds a common imx cpuidle driver, some common mach-mx5 level cpuidle functionality, and an i.MX51 instance of using this driver.

The patch series is based on v3.1-rc2.

Changes since v1:
* To address all the problems found during review of v1, a complete re-write was needed.

Much better than the last version, thanks.

And this one should go to arch/arm/mach-mx5/cpuidle.c, then we have all i.MX5 specific cpuidle stuff together without ifdeffing the code. I assume that cpuidle support for i.MX53 will look identically, right?

Yes, let's not separate only for i.MX51. i.MX53 and even i.MX6 might look similar. They can always tune the exit latency criteria if needed.
