[PATCH 1/5] powerpc/dts: add MPIC v4.3 dts node

2013-06-14 Thread Minghuan Lian
For the latest platform T4 and B4, MPIC controller has been updated to v4.3. This patch adds a new file to describe the latest MPIC. The MSI blocks number is increased to four, the registers number of each block is increased to sixteen. MSIIR1 has been added to access these sixteen MSI registers.
