From 20d1836eeab7a2335892b970575bfb1e9bcac567 Mon Sep 17 00:00:00 2001 From: Venkatesh Yadav Abbarapu <venkatesh.abbarapu@amd.com> Date: Wed, 11 Oct 2023 08:45:15 +0530 Subject: [PATCH] spi: cadence_ospi_versal: Add support for 64-bit address When 64-bit address is passed only lower 32-bit address is getting updated. Program the upper 32-bit address in the DMA destination memory address MSBs register.
