From 5a523605afa7d3b54b2e7041f8c9e6bc39872a7e Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Tue, 10 Sep 2013 15:45:05 +0530 Subject: regulator: core: provide fixed voltage in desc for single voltage rail If given rail has the single voltage (n_voltages = 1) then provide the rail voltage through regulator descriptor so that core can use this value for finding voltage. This will avoid the implementation of the callback for get_voltage() or list_voltage() callback on regulator driver.
