Subject: [PATCH 0/2] bus: imx-aipstz: fix probe-related issues
Date: Mon, 7 Jul 2025 19:46:26 -0400 [thread overview]
Message-ID: <20250707234628.164151-1-laurentiumihalcea111@gmail.com> (raw)
From: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>
Since the introduction of the i.MX AIPSTZ bridge driver via commit
796cba2dd4d9 ("bus: add driver for IMX AIPSTZ bridge"), a couple of
problems have been reported by Mark Brown and Alexander Stein. Namely:
1) The driver doesn't get compiled when using the ARM64
defconfig [1].
2) The children of the SPBA bus do not get probed [2].
These issues are addressed here by:
1) Enabling the driver config option in the ARM64 defconfig.
2) Replacing devm_of_platform_populate() with
of_platform_populate() and passing a reference to the bus OF
match table to it.
