[PATCH] Fixes for MPC512x PSC

[Albrecht Dreß]

Hi Steve:

A while ago I posted a patch which improves the baud rate calculation of the '5200, but also refactors the driver a little bit so it also influences the '512x.  However, there has been some confusion about the config regs of the 521x's uart.  It would be great if you colud have a look at the patch <http://lists.ozlabs.org/pipermail/linuxppc-dev/2010-March/081477.html>, in particular function mpc512x_psc_set_baudrate(), and comment on it.  Some more infor is in the thread <http://lists.ozlabs.org/pipermail/linuxppc-dev/2010-March/080867.html>.

Thanks in advance,
Albrecht.

Betreff: [PATCH] Fixes for MPC512x PSC

> This will apply on the mpc512x-v2.6.33-devel branch of the DENX git

>  In clock.c replaced clk_enable with mpc5121_clk_enable as clk_functions

>  Added initialization of the FIFO address and size registers based on

>  Removed port-number property from mpc5121ads device tree as the driver
> doesn't use it.
>  Made sure PSC clocks are enabled early for console.
>  Made sure interrupt is requested with IRQF_SHARED as they share the
> FIFO irq.
>  Moved initialization of CSR to mpc52xx_uart_set_termios so it is done
> for the MPC512x
>  and also so it is done early in the console setup.
