On Exynos5422 and Exynos5800 we support 12 cpufreq steps (200-1300 MHz) for LITTLE and 18 steps for big core (200-1700 MHz). Add respective cooling cells. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org>

* This file provides desired ordering for Exynos5422: CPU[0123] being the A7.
|
|
*
|
|
* The Exynos5420, 5422 and 5800 actually share the same CPU configuration
|
|
* but particular boards choose different booting order.
|
|
*
|
|
* Exynos5420 and Exynos5800 always boot from Cortex-A15. On Exynos5422
|
|
* booting cluster (big or LITTLE) is chosen by IROM code by reading
|
|
* the gpg2-1 GPIO. By default all Exynos5422 based boards choose booting
|
|
* from the LITTLE: Cortex-A7.
