From d97556c8012015901a3ce77f46960078139cd79d Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 5 Jan 2017 11:07:18 -0800 Subject: ARM: dts: Fix omap3 off mode pull defines We need to also have OFFPULLUDENABLE bit set to use the off mode pull values. Otherwise the line is pulled down internally if no external pull exists. This is has some documentation at: http://processors.wiki.ti.com/index.php/Optimizing_OMAP35x_and_AM/DM37x_OFF_mode_PAD_configuration Note that the value is still glitchy during off mode transitions as documented in spz319f.pdf "Advisory 1.45". It's best to use external pulls instead of relying on the internal ones for off mode and even then anything pulled up will get driven down momentarily on off mode restore for GPIO banks other than bank1.
