The omap3_pmx_core pinmux device in the device tree handles the system controller module (SCM) PADCONFS fonction. Its control registers are split in two distinct areas, with other SCM registers in-between. Those other registers can't thus be requested by other drivers as the memory region gets reserved by the pinmux driver. Split the omap3_pmx_core device tree node in two for the two memory regions. The second region address and size depends on the SoC model. The change in omap3.dtsi fixes an "external abort on non-linefetch" when doing cat /sys/kernel/debug/pinctrl/.../pins on a Nokia N900. Note that the core2 padconf region is different for 3430 vs 3630, and does not exist on 3517 as noted by Nishanth Menon <nm@ti.com>.
