From mboxrd@z Thu Jan 1 00:00:00 1970 From: davidb@codeaurora.org (David Brown) Date: Wed, 2 Nov 2011 11:36:10 -0700 Subject: [RFC PATCH 13/34] msm: clock-debug: Implement a default is_enabled() In-Reply-To: <1320258991-22325-1-git-send-email-davidb@codeaurora.org> References: <1320258991-22325-1-git-send-email-davidb@codeaurora.org> Message-ID: <1320258991-22325-14-git-send-email-davidb@codeaurora.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Stephen Boyd Some clocks are simple enough that determining if they are enabled or disabled can be done by reading the 'count' member of struct clk. Implement support for such clocks in clock-debug.c so that these types of clocks don't need to implement the is_enabled() ops.
