[PATCH 09/40] pl050: introduce pl050_mouse_class_init() and pl050_mouse_


From: Mark Cave-Ayland
Subject: [PATCH 09/40] pl050: introduce pl050_mouse_class_init() and pl050_mouse_realize()
Date: Wed, 29 Jun 2022 13:39:55 +0100

Introduce a new pl050_mouse_class_init() function containing a call to
device_class_set_parent_realize() which calls a new pl050_mouse_realize()
function to initialise the PS2 mouse device.
