Subject: [PATCH v1 3/4] qoriq_thermal: No need to program site adjustment register
Date: Thu,  5 Jan 2023 18:17:47 +0800	[thread overview]
Message-ID: <20230105101748.6714-4-alice.guo@oss.nxp.com> (raw)
In-Reply-To: <20230105101748.6714-1-alice.guo@oss.nxp.com>

From: Pankit Garg <pankit.garg@nxp.com>

No need to program site adjustment register, as programming
these registers do not give accurate value and also these
registers are not mentioned in Reference Manual.
