From 885fd621a309a2c3f8e8d41bdc8ff893221dc478 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sun, 16 Mar 2025 14:51:44 +0100 Subject: ram: renesas: dbsc5: Make struct renesas_dbsc5_board_config public Make struct renesas_dbsc5_board_config {} definition public via include/dbsc5.h, so this structure can be defined in board files and passed into the DBSC5 DRAM driver by overriding weak function dbsc5_get_board_data() on board level.
