From f6fbc397066e57d180aebc62e6bf52464d06bd76 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Sat, 29 Aug 2020 23:07:28 +0200 Subject: build: define PWM_SUPPORT arch feature flag As the PWM has its own sub-system in the Linux kernel, I think it should be handled in the same way as GPIO, RTC, PCI... This patch introduces a specific feature flag "pwm" and the "leds-pwm" kernel module as the first customer.
