From 885087b3288346e2e09da92e506e5f390cd4ad29 Mon Sep 17 00:00:00 2001
From: Kumar Gala <galak@kernel.org>

Subject: [PATCH] drivers: pwm: Update drivers to use devicetree Kconfig symbol

Update pwm drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.

We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.
