From e40219d5e4b2177bfd4d885e7b64e3b236af40ac Mon Sep 17 00:00:00 2001 From: Jerry Lin Date: Fri, 6 Sep 2019 09:06:14 +0800 Subject: [PATCH] staging: olpc_dcon: allow simultaneous XO-1 and XO-1.5 support This patch remove model related configuration. Since the module can decide which platform data to use itself base on current running olpc board. Also change module dependency from (GPIO_CS5535 || GPIO_CS5535=n) to (GPIO_CS5535 || ACPI) because original one does not make any sense and module only doing real work when GPIO_CS5535 or ACPI is setted.
