Re: [U-Boot] [PATCH] powerpc/mpc85xx: Fix the I2C bus speed error on p1022
Hello yuantian.t...@freescale.com, Am 06.09.2013 04:45, schrieb yuantian.t...@freescale.com: From: Tang Yuantianyuantian.t...@freescale.com The source clock frequency of I2C bus on p1022 is the platform(CCB) clock, not CCB/2. The wrong source clock frequency leads to wrong I2C bus speed setting. so, fixed it.
