The maximum UART speed is stated to be 4Mbps in the datasheet. Have you

I tried increasing the bps to 1152000 but it didn't work.
Hi all,
Newer u-boot versions may chose a different (better) PLL6 / PLL5 setting
and/or different voltage settings. Unfortunately the old linux-sunxi-3.4
kernels have a number of hardcoded assumptions about PLL5 speed, and in some
cases override the bootloader chosen PLL6 / voltages in a bad way.
Some fex files contain wrong values, causing stability issues.

Before the u-boot dram cleanup u-boot would always set PLL5 factor m to
2 (reg value 1) and div p to 1, and get_cmu_clk in the nand code
would calculate the pll5p clk like this:
clk = 24 * factor_n * factor_k / div_p / factor_m;
aka:
clk = 24 * factor_n * factor_k / (div_p * factor_m);
This is
Keep the PLL6 frequency as it is set by the bootloader, it may be used as
parent for the mbus, and if we change it we may be changing the mbus frequency,
all peripherals (*) using pll6 are already capable of dealing with it running at
a different frequency.
*) Only mmc uses pll6 as a parent by
