Subject: [PATCH v4 3/5] leds: simatic-ipc-leds-gpio: add new model 227G
Date: Tue, 23 Aug 2022 12:23:42 +0200 [thread overview]
Message-ID: <20220823102344.17624-4-henning.schild@siemens.com> (raw)
In-Reply-To: <20220823102344.17624-1-henning.schild@siemens.com>
This adds support of the Siemens Simatic IPC227G. Its LEDs are connected
to GPIO pins provided by the gpio-f7188x module. We make sure that
gets loaded, if not enabled in the kernel config no LED support will be
available.
