[Edwin Chiu <edwinchiu0505tw@gmail.com>]

This is a patch series for cpuidle driver for Sunplus SP7021 SoC.

Sunplus SP7021 is an ARM Cortex A7 (4 cores) based SoC. It integrates
many peripherals (ex: UART, I2C, SPI, SDIO, eMMC, USB, SD card and 
etc.) into a single chip. It is designed for industrial control.

Changes in v3
 - Rearrangement #include sequence
 - Change remark style to /*~*/
 - Align author email address to same as sob
 - Optimal code
Changes in v4
 - According Rob Herringrobh's comment
   There is no need for this binding.
   Just wanting a different driver is not a reason
   for a duplicate schema.
   So remove yaml file and submit driver again.
Changes in v5
 - According Krzysztof's comment
   You either use appropriate compatible in DT
   or add your compatible to cpuidle-arm.
   Even if this did not work, then the solution is to
   use common parts, not to duplicate entire driver.
   According Sudeep's comment
   In short NACK for any dedicated driver for this platform,
   use the generic cpuidle-arm driver with appropriate platform hooks
   Create cpuidle-sunplus.c in arch/arm/mach-sunplus/
   for hook generic cpuidle-arm driver
