Subject: [PATCH v2 9/9] HID: amd_sfh: Add light chromaticity for SFH1.1
Date: Tue, 19 Sep 2023 13:40:54 +0530	[thread overview]
Message-ID: <20230919081054.2050714-10-Basavaraj.Natikar@amd.com> (raw)
In-Reply-To: <20230919081054.2050714-1-Basavaraj.Natikar@amd.com>

In most cases, ambient color sensors also support the x and y light
colors, which represent the coordinates on the CIE 1931 chromaticity
diagram. Thus, add light chromaticity x and y for SFH1.1.
