[PATCH] dscc4: scc changes
From: Francois Romieu <romieu@fr.zoreil.com> - more #define for specific bits; - more scc_patchl use; - just say no to bozo programming: + SCC core _really_ disabled at startup; + Interrupts Mask Register setup and SCC core activation are done as late as possible (i.e. in dscc4_open()); + they are reverted if dscc4_open() fails; + as well as unconditionnaly in dscc4_close(); - more or less paranoid quirk in Xpr handler.
