Subject: [PATCH v2 1/2] dt-bindings: pinctrl: samsung: google,gs101-pinctrl needs a clock
Date: Fri, 26 Apr 2024 14:10:46 +0100	[thread overview]
Message-ID: <20240426-samsung-pinctrl-busclock-v2-1-8dfecaabf020@linaro.org> (raw)
In-Reply-To: <20240426-samsung-pinctrl-busclock-v2-0-8dfecaabf020@linaro.org>

The pin controller on Google Tensor gs101 requires a bus clock for
register access to work. Add it.

Signed-off-by: André Draszik <andre.draszik@linaro.org>

---
As we only have the one clock here, please let me know if the
clock-names should be removed. Having it does make
/sys/kernel/debug/clk/clk_summary look nicer / more meaningful though
:-)
