[PATCH] ARM: dts: omap: dm816x: Correct pinctrl register
From: Andrew Goodbody
Date: Thu Mar 12 2026 - 10:17:30 EST
The delcaration in the pinmux device for the pinctrl registers is not
correct. These registers are actually 32 bits wide, not 16. Also the
mask for functional bits is also wrong. Functional bits are 0-4, not
0-3. So the mask needs to changed to 0x1f.
This information is taken from the TMS320DM816x DaVinci
Digital Media Processors Technical Reference Manual.
