Use delayed timer as default instead of deferrable timer in order to monitor the GPU status regardless of CPU idle. Signed-off-by: Lukasz Luba <lukasz.luba@arm.com> --- Hi all, I've missed the Lima driver while working on Panfrost patch for fixing the issue with default devfreq framework polling mode.
