 Hi, 
 
this is Madhusudhan J from KPITCummins Bangalore India . 
I have issue with uart driver   in linux kernel 2.6.24
(drivers\serial\Mpc52xx_uart.c)
I am using platform  mpc5121e to communicating to modem through serial
driver. i am not able to communicate with  UART
driver(drivers\serial\Mpc52xx_uart.c).
In this file i could not see 512x uart operations but UART opration are
there for 52xx. could you please let me know how to make it work with
uart driver on 5121e platform?.
 
Appriciate your help in this regard.
 
Regards,
Madhu

Can you tell more about which kernel you are using?

Please use the lates git head called "ads5121" from denx.
I am using that one, and the UART works fine.
There are although a lot of tricky details in your device-tree that have to
be correct in order for this driver to work.
Are you using you own hardware, or are you using the ADS5121?
What version of the MPC5121e processor do you have? M34K, 2M34K or M36P?
