Subject: [PATCH RESEND v2 6/6] ARM: dts: samsung: exynos4212-tab3: Drop
dummy mic bias regulators
Add the samsung,tab3-audio compatible that makes mic bias regulators
non-required, and drop the dummy main/sub mic bias regulators that
don't exist in hardware.
Signed-off-by: Artur Weber <aweber.kernel@...il.com>

Changes in v2:
- Rename earmic bias reg node to voltage-regulator-4
