From 2837a1d4161caec7dffefa03505b87f056c1f5bb Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Thu, 21 Feb 2013 22:42:38 -0700 Subject: [PATCH] ARM: bcm2835: fix I2C module clock rate BCM2835-ARM-Peripherals.pdf states that the I2C module's input clock is nominally 150MHz, and that value is currently reflected in bcm2835.dtsi. However, practical measurements show that the rate is actually 250MHz, and this agrees with various downstream kernels. Switch the I2C clock's frequency to 250MHz so that the generated bus clock rate is accurate.
