From 029180b1c99046831c33ed43fdbdb620506cb15b Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Thu, 18 Jun 2015 15:41:33 +0100 Subject: drivers: firmware: psci: define more generic PSCI_FN_NATIVE macro This patch replaces the definition and usage of PSCI_0_2_FN_NATIVE with the new and more generic macro PSCI_FN_NATIVE that can be used with any version. This will be useful for the new features introduced in PSCIv1.0 and for any future revisions.
