Subject: [PATCH V4 1/4] dt-bindings: soc: qcom: Remove SPI controller maximum frequency binding
Date: Tue, 18 Sep 2018 23:37:23 +0530	[thread overview]
Message-ID: <1537294047-12093-2-git-send-email-dkota@codeaurora.org> (raw)
In-Reply-To: <1537294047-12093-1-git-send-email-dkota@codeaurora.org>

SPI controller driver should maintain the maximum frequency
of the controller instead of relying on device tree bindings.
Because maximum frequency is specific property of SPI
controller.
