Subject: [U-Boot] [PATCH 2/2][for v2008.10] 85xx: Using proper I2C source clock divider for MPC8544
Date: Thu, 16 Oct 2008 21:58:50 -0500 [thread overview]
Message-ID: <1224212330-14491-2-git-send-email-galak@kernel.crashing.org> (raw)
In-Reply-To: <1224212330-14491-1-git-send-email-galak@kernel.crashing.org>
The MPC8544 RM incorrect shows the SEC_CFG bit in PORDEVSR2 as being
bit 26, instead it should be bit 28. This caused in incorrect
interpretation of the i2c_clk which is the same as the SEC clk on
MPC8544. The SEC clk is controlled by cfg_sec_freq that is reported
in PORDEVSR2.
