From 5f8d505e3a60b957530c7ad9b1214cc440d8b951 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 30 Oct 2023 11:48:00 +0000 Subject: [PATCH] hw/input/stellaris_gamepad: Remove StellarisGamepadButton struct MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently for each button on the device we have a StellarisGamepadButton struct which has the irq, keycode and pressed state for it. When we convert to qdev, the qdev property and GPIO APIs are going to require that we have separate arrays for the irqs and keycodes. Convert from array-of-structs to three separate arrays in preparation. This is a migration compatibility break for the stellaris boards (lm3s6965evb, lm3s811evb).
