JIRA: https://issues.redhat.com/browse/RHEL-147786 commit d2e6fb2c31a07f34e5e7533df11431cb0d2ecf9f Author: Ricky Wu <ricky_wu@realtek.com> Date: Tue, 12 Aug 2025 11:08:11 +0800 This patch adds support for Over Current Protection (OCP) to the Realtek USB card reader driver. The OCP mechanism protects the hardware by detecting and handling current overload conditions. This implementation includes: - Register configurations to enable OCP monitoring. - Handling of OCP interrupt events and associated error reporting. - Card power management changes in response to OCP triggers. This enhancement improves the robustness of the driver when operating in environments where electrical anomalies may occur, particularly with SD and MS card interfaces.
