Subject: [PATCH 0/3] Add gamma lut support for mt8195
Date: Mon, 22 Aug 2022 17:19:42 +0800 [thread overview]
Message-ID: <20220822091945.21343-1-zheng-yan.chen@mediatek.com> (raw)
Since the gamma_set_common() function for previous SoC,
such as mt8173 and mt8183, is designed for 9bit-to-10bit
conversion.
mt8195 is using 10bit-to-12bit conversion, which is
not compatible with the previous function.
Thus, need to update the function to fit the need of mt8195.
