From a897ea13f7a801e6baba8d4985f459042712244c Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Wed, 8 Oct 2008 09:02:11 -0600 Subject: powerpc/mpc5200: fix build warnings on mpc52xx_psc_spi driver The register definitions have been changed for the mpc5200 PSC ports to cover some of the changes in the mpc5200b. One change is that the ccr register is now a u32 instead of a u16. However, for the purposes of this driver we want to continue to use 16 bit access to avoid changing the existing (working) behaviour. This patch allows the driver to continue to do 16 bit accesses without the compiler complaining about it.

The bindings specifies verbose information for the devices, but it doesn't fit in the I2C ID's 20 characters limit. The limit won't change[2], and the bindings won't change either as they're correct.
