From 2ca9e472c70f15de768ab200571e2f6634f66394 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Mon, 25 Apr 2022 18:45:43 -0700 Subject: [PATCH] soc: rockchip: power-domain: Replace dsb() with smb() It's unclear if these are really needed at all, but seemingly their purpose is only as a write barrier. Use the general macro instead of the ARM-specific one. This driver is partially marked for COMPILE_TEST'ing, but it doesn't build under non-ARM architectures. Fix this up before *really* enabling it for COMPILE_TEST.
