From 752e4b6c8efb5bd624f316f7a9686d9956d55dd7 Mon Sep 17 00:00:00 2001 From: Ashok Reddy Soma Date: Mon, 10 Jul 2023 14:11:59 +0200 Subject: [PATCH] mmc: zynq_sdhci: Dll reset only for ZynqMP platform Dll reset is needed only for ZynqMP platforms, add condition in tuning to call arasan_zynqmp_dll_reset() just for ZynqMP platforms. On other platforms like Versal NET, If this condition is not added, we see PLM error messages when dll reset smc is called.
