From 8f50db4b5c79af2ba54f5fbe8a5173fd7f37a493 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Wed, 30 Dec 2020 16:37:44 +0100 Subject: powercap/drivers/dtpm: Fix __udivdi3 and __aeabi_uldivmod unresolved symbols 32-bit architectures do not support u64 divisions, so the macro DIV_ROUND_CLOSEST is not adequate as the compiler will replace the call to an unexisting function for the platform, leading to unresolved references to symbols. Fix this by using the compatible macros: DIV64_U64_ROUND_CLOSEST and DIV_ROUND_CLOSEST_ULL.
