From: Thomas Abraham <redacted> For Exynos5420 platforms, add CPU operating points and CPU regulator supply properties for migrating from Exynos specific cpufreq driver to using generic cpufreq driver. Changes by Bartlomiej: - split Exynos5420 support from the original patch Changes by Ben Gamari: - Port to operating-points-v2 Cc: Kukjin Kim <redacted> Cc: Doug Anderson <dianders@chromium.org> Cc: Javier Martinez Canillas <redacted> Cc: Andreas Faerber <afaerber@suse.de> Cc: Sachin Kamat <redacted> Cc: Thomas Abraham <redacted> Signed-off-by: Ben Gamari <redacted> Signed-off-by: Bartlomiej Zolnierkiewicz <redacted> --- arch/arm/boot/dts/exynos5420.dtsi | 122 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 122 insertions(+)
