Subject: [PATCH 1/2] arm64: dts: apple: t8103: Rename clk24 to clkref
Date: Sun, 12 Dec 2021 10:43:45 +0900 [thread overview]
Message-ID: <20211212014346.69320-1-marcan@marcan.st> (raw)
We now know that this frequency comes from the external reference
oscillator and is used for various SoC blocks, and isn't just a random
24MHz clock, so let's call it something more appropriate.
