    Subject[PATCH AUTOSEL 6.6 38/51] accel/ivpu: Disable d3hot_delay on all NPU generations
    Date
    From: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com>

    [ Upstream commit a7f31091ddf457352e3dd7ac183fdbd26b4dcd04 ]

    NPU does not require this delay regardless of the generation.
    All generations are integrated into the SOC.
