From 32400a7e872fe620ab52ec32521e839a71ffb54c Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Mon, 30 Oct 2023 11:47:59 +0000 Subject: qdev: Add qdev_prop_set_array() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of exposing the ugly hack of how we represent arrays in qdev (a static "foo-len" property and after it is set, dynamically created "foo[i]" properties) to boards, add an interface that allows setting the whole array at once. Once all internal users of devices with array properties have been converted to use this function, we can change the implementation to move away from this hack.
