addy ke b4a7bd7a38 i2c: rk3x: fix divisor calculation for SCL frequency ... I2C_CLKDIV register descripted in the previous version of RK3x chip manual is incorrect. Plus 1 is required. The correct formula: - T(SCL_HIGH) = T(PCLK) * (CLKDIVH + 1) * 8 - T(SCL_LOW) = T(PCLK) * (CLKDIVL + 1) * 8 - (SCL Divsor) = 8 * ((CLKDIVL + 1) + (CLKDIVH + 1)) - SCL = PCLK / (CLK Divsor) It will be updated to the latest version of chip manual.
