Subject: [PATCH 02/33] clk: ast2600: Add FSI parent clock with correct rate
Date: Thu, 15 Feb 2024 16:07:28 -0600	[thread overview]
Message-ID: <20240215220759.976998-3-eajames@linux.ibm.com> (raw)
In-Reply-To: <20240215220759.976998-1-eajames@linux.ibm.com>

In order to calculate correct FSI bus clocks, the FSI clock must
correctly calculate the rate from the parent (APLL / 4).
