With all such cases this should be dedicated enum. Best regards, Krzysztof

mt8195 uses 10bit-to-12bit gamma-LUT, which is not compatible with current 9bit-to-10bit gamma-LUT. This patch thus add constant compatible for mt8195, which means that mt8195 should only use specified mt8195 gamma driver data. Also, delete related compatible from enum, to ensure that mt8195 will not accidentally get others' gamma driver data and thus cause fatal error.
