Subject: [PATCH 3/8] ARM: OMAP2+: Remove bogus warnings for machines without twl PMIC

From: Tony Lindgren <[email-masked]>
Date: Wed, 9 Oct 2019 17:12:19 -0700

In general we want to see a quiet dmesg output with no errors or warnings
unless something is really wrong and needs attention. We currently see
these bogus warnings on boot:

twl: not initialized
twl6030_uv_to_vsel:OUT OF RANGE! non mapped vsel for 1375000 Vs max 1316660
twl6030_uv_to_vsel:OUT OF RANGE! non mapped vsel for 1375000 Vs max 1316660
twl6030_uv_to_vsel:OUT OF RANGE! non mapped vsel for 1375000 Vs max 1316660
twl6030_uv_to_vsel:OUT OF RANGE! non mapped vsel for 1375000 Vs max 1316660
...

Let's avoid these by checking if a device tree node for cpcap PMIC exists.
