From 1690e35f9b95e0efe063d76a7ab485db3e8d3bc5 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 8 May 2014 16:56:28 +0200 Subject: [PATCH] misc: atmel_pwm: only build for supported platforms There is architecture code in mach-at91 that depends on the CONFIG_ATMEL_PWM symbol in order to call the soc-specific at91_add_device_pwm function. While all of this is about code that will be removed in the future, using DT probing and the PWM framework, we currently get a build failure: arch/arm/mach-at91/built-in.o: In function `at91_pwm_leds': arch/arm/mach-at91/leds.c:88: undefined reference to `at91_add_device_pwm' This patch ensures we only try to build this driver on platforms on which it will build and work.
