From 3d0aa91984463a922c1c1a3abef6ff117bb5f418 Mon Sep 17 00:00:00 2001 From: Maya Erez Date: Fri, 26 Apr 2019 18:43:37 +0300 Subject: [PATCH] wil6210: remove HALP for Talyn devices In Talyn the HW is responsible for power management enter / exit flow, hence the deep sleep exit latency is significantly shorter than in Sparrow. In such a case HALP feature, that is meant to prevent long PCIe blocking accesses, is no longer needed and can be removed for Talyn.
