Subject: i2c: lpc32xx: use api to get hclk instead of fix value
X-Git-Tag: v2015.10-rc2~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b395a996a65572a5e64d648ac4dc4d43a53ea38b;p=platform%2Fkernel%2Fu-boot.git

i2c: lpc32xx: use api to get hclk instead of fix value

The HCLK is not constant and can take different value; use the api function to get the value of the HCLK for the I2C clock high and low computation.
