From b395a996a65572a5e64d648ac4dc4d43a53ea38b Mon Sep 17 00:00:00 2001 From: Sylvain Lemieux Date: Mon, 27 Jul 2015 13:37:37 -0400 Subject: [PATCH] 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.
