33 * the digital control register for all color control looks like:
34 * +-----------------+------------------+
35 * | [7:0] | [15:8] |
36 * +-----------------+------------------+
37 * | 0x020f | 0x020e |
38 * --------------------------------------
39 * it is used to calculate the digital gain times value(integral + fractional)
40 * the [15:8] bits is the fractional part and [7:0] bits is the integral
41 * calculation equation is:
42 * gain value (unit: times) = REG[15:8] + REG[7:0]/0x100
43 * Only value in 0x0100 ~ 0x0FFF range is allowed.
44 * Analog gain use 10 bits in the registers and allowed range is 0 ~ 960
