Subject: ibm_ocp ethernet OPB clocks
Date: Thu, 08 Jul 2004 18:07:26 -0400 [thread overview]
Message-ID: <40EDC59E.9020403@rossvideo.com> (raw)
In pretty much all versions of the kernel (I checked 2.4.x, 2.6.7), one
finds in drivers/net/ibm_ocp/ibm_ocp_emac.h:
#define EMAC_M1_OPB_CLK_66 0x00000010 /* 66Mhz */
#define EMAC_M1_OPB_CLK_83 0x00000008 /* 83hz */
I believe these bitfield values are reversed... at least according to
the 440GX usermanual, page 879. Bug/typo? Is the usermanual wrong? Or
perhaps other 4xx series processors have different definitions?
The definitions for 100MHz and >100MHz appear to be correct though.
Is there a current maintainer for this driver?
