- Fix 'function-mask' referring to TRM Section 7.4.4: "Pad Functional Multiplexing and Configuration". - Fix 'omap3_pmx_core' referring to TRM Table 7-4: "Core Control Module Pad Configuration Register Fields" - Fix 'omap3_pmx_wkup' referring to TRM Table 7-6: "Wake-Up Control Module Pad Configuration Register Fields".Maybe mention which TRM this is so people will know.quoted

Which TRM are you looking at?I used TRM Omap35xx, and yes in the TRM Omap36xx 0x234 is fine. I'll fix this in the next revision of this patch.
OK

Ack for the function-mask change for omap3, looks like those bits are not used.quoted

So yes 0x2a00 is the right start as otherwise we're missing some wkup registers. But the size should be 0x50 instead of 0x54 as the JTAG_TDO[31:16] is already un-used in TRM? Or it could be 0x60 if we want to map also the reserved GPIO128[31:16].Why not 0x5c ? GPIO128[31:16] starts at 0x2a5a and its size is 2 bytes.
Oops yes 0x5c as it's 2 bytes. So the original value is fine then. Regards, Tony
