Subject: [PATCH 3/8] HID: amd_sfh: Add support for light color temperature
Date: Fri, 15 Sep 2023 10:46:58 +0530	[thread overview]
Message-ID: <20230915051703.1689578-4-Basavaraj.Natikar@amd.com> (raw)
In-Reply-To: <20230915051703.1689578-1-Basavaraj.Natikar@amd.com>

In most cases, ambient color sensors also support light color temperature.
As a result, add support of light color temperature.
