On DA850/OMAP-L138 SoC, the PLL which supplies the clock to CPU also
feeds the UART and the UART input frequency can change when the CPU
frequency is scaled.
This patch adds cpufreq support for 8250 serial driver. A clk structure
member has been added to
Use for_each_set_bit_from to iterate over all the set bit in a memory
region.

This patch was submitted 2 years ago but didn't make it to the mainline. Now
i am reposting it.
Can you fix it instead of just reposting it ?

Clock for EMIF is derived from ASYNC clock domain(PLL0_SYSCLK3) and was
configured with fixed divider as there was no significant performance
degradation with existing NAND/NOR EMIF devices if it is not
reconfigured accordingly at different OPPs.
On systems where devices other than NAND/NOR are
