Subject: [PATCH v2] ARM: dts: aspeed: clemente: Add HDD LED GPIO
Date: Tue, 30 Sep 2025 10:49:23 +0800 [thread overview]
Message-ID: <20250930-leo-dts-add-shunt-resistor-v2-1-8712984f04c4@gmail.com> (raw)
Define a GPIO expander pin for the HDD LED and expose it via the
LED subsystem. This allows the BMC to control the front panel
HDD activity LED.
Signed-off-by: Leo Wang <leo.jt.wang@gmail.com>
