However, according to the m31 reference manual, it should be serial_pll_clk. Guennadi always used a 20 MHz clock that was by chance changed to a 45 MHz that fits in the mt9t031 spec. Now the clocks are computed and output correctly (measured on oscillo).

You're right - I got the IOMUX tables wrong and thought UART0 pins are selected unconditionally. But as it turns out TXD1/RXD1 is for UART0 (mxc_uart_device0), TXD2/RXD2 for UART1 (mxc_uart_device1) etc. Below is a new patch.
