From d7a354dab0fb45ff2161a535003dadc7cdb59f95 Mon Sep 17 00:00:00 2001 From: Tarun Tuli Date: Wed, 21 Jun 2023 19:45:43 +0000 Subject: mb/google/brya/acpi: Set polling timing for DL23 and LD23 to 2ms Reducing the polling time from 16ms to 2ms. Experimentally we have determined that the link state normally takes approximately 3.5ms to update and therefore we were waiting longer than necessary. TEST=build and confirm we are not waiting the extended period.
