Subject: [PATCH 1/2] pwm: Add stubs for pwm operations
Date: Wed, 18 May 2011 18:30:52 +0530	[thread overview]
Message-ID: <1305723652-22737-1-git-send-email-mpallaka@codeaurora.org> (raw)

Chip drivers that support both pwm and non-pwm modes
would encounter compilation errors if the platform doesn't
have support for pwm, even though the chip is programmed
to work in non-pwm mode. Add stubs for pwm functions to
avoid compilation errors in these scenarios.
