Vladimir Zapolskiy ea16c6a13b i2c: lpc32xx: correct sanity check for requested bus speed ... LPC32xx has 3 I2C bus controllers, 2 of them are used as generic ones and their parent clock is HCLK and CLK_HI/CLK_LO registers are 10 bit wide. This means that if HCLK is 104MHz, then minimal configurable I2C clock speed is about 51KHz. Only USB OTG I2C bus controller CLK registers are 8 bit wide, thus in assumption that peripheral clock is 13MHz it allows to set the minimal bus speed about 25.5KHz. Check for negative half clock value is removed since it is always false. The change fixes the following problem for I2C busses 0 and 1: => i2c dev 0 Setting bus to 0 => i2c speed 100000 Setting bus speed to 100000 Hz Failure changing bus speed (-22) Signed-off-by: Vladimir Zapolskiy <vz@mleia.com> Tested-by: Sylvain Lemieux <slemieux@tycoint.com>		2015-08-18 13:45:59 -04:00
