[RFC 2/2] mpc52xx_psc_spi device driver must not touch port_config and cdm

2008-01-07 Thread Grant Likely
From: Grant Likely <[EMAIL PROTECTED]> It is dangerous for an mpc52xx device driver to modify the port_config register. If the driver is probed incorrectly, it will change the pin IO configuration in ways which may not be compatible with the board. port_config should be set up by the bootloader,
