From ea6533ada828cf71b9359f566be0f9c640022543 Mon Sep 17 00:00:00 2001 From: Anup Patel Date: Tue, 11 Jul 2023 09:00:31 +0530 Subject: [PATCH] lib: utils/gpio: Fix RV32 compile error for designware GPIO driver Currently, we see following compile error in the designeware GPIO driver for RV32 systems: lib/utils/gpio/fdt_gpio_designware.c:115:20: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] 115 | chip->dr = (void *)addr + (bank * 0xc); | ^ lib/utils/gpio/fdt_gpio_designware.c:116:21: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] 116 | chip->ext = (void *)addr + (bank * 4) + 0x50; We fix the above error using an explicit type-cast to 'unsigned long'.
