Re: MPC52xx: sysfs failure on adding new device driver

Hi Grant

In the mean time, here's another option:  Leave
arch/ppc/syslib/mpc52xx_devices.c alone, but modify the table in the
board setup code to assign specific drivers to the PSC devices before
the table is parsed by the platform bus.  This has the added advantage
of eliminating the need for mpc52xx_match_psc_function() and it's
cousins.

+	/* Assign driver names to PSC devices */
+	ppc_sys_platform_devices[MPC52xx_PSC1].name = "mpc52xx-psc.uart";
+	ppc_sys_platform_devices[MPC52xx_PSC2].name = "mpc52xx-psc.uart";
+	ppc_sys_platform_devices[MPC52xx_PSC3].name = "mpc52xx-psc.spi";

Yes, I kinda like that. That maybe the cleanest way, just 1 line of code 
per device and when no subfn is assigned, nothing is loaded.

I don't really like messing manually with the ppc_sys_platform 
"internals" outside of the ppc_sys code, but maybe creating a call like

ppc_sys_assign_subfn(MPC52xx_PSC1,"uart");


and place it in the ppc_sys code so that other platforms havin such 
"multi usage" device all have an uniform way of handling that. Galak ?
