Subject: [PATCH v5 6/7] clk: clk-axi-clkgen move to min/max()
Date: Mon, 12 May 2025 15:46:49 +0100 [thread overview]
Message-ID: <20250512-dev-axi-clkgen-limits-v5-6-a86b9a368e05@analog.com> (raw)
In-Reply-To: <20250512-dev-axi-clkgen-limits-v5-0-a86b9a368e05@analog.com>
From: Nuno Sá <nuno.sa@analog.com>
Instead of using the type versions of min/max(), use the plain ones as
now they are perfectly capable of handling different types like
unsigned and non negative integers that are compiletime constant.
