Subject: [PATCH 2/4] intel_idle: move one more model specific workaround into the newly created seperate function
Date: Mon, 17 Jul 2023 15:18:54 +0000 [thread overview]
Message-ID: <20230717151856.2529029-2-arjan@linux.intel.com> (raw)
In-Reply-To: <20230717151856.2529029-1-arjan@linux.intel.com>
From: Arjan van de Ven <arjan@linux.intel.com>
byt_auto_demotion_disable_flag (for baytrail) handling can now be moved into the newly created
model_specific_fixups() function.
This frees up intel_idle_init_cstates_icpu() from containing model specific information direclty
