Xu Yang · opsiff · commit ee7e509b24c7 · 2026-03-11T17:28:18.000+08:00
[ Upstream commit 27ee0869d77b2cb404770ac49bdceae3aedf658b ] Disabling PHYs in runtime usually causes the client with external abort exception or similar issue due to lack of API to notify clients about PHY removal. This patch removes the possibility to unbind i.MX PHY drivers in runtime.
