From f8e125c995384771a2dcd33d299e21ff8879e3bf Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Tue, 30 Jan 2024 15:51:06 +0100 Subject: [PATCH] arm64: zynqmp: Fix kr260 clock wiring kr260 revA/revA01 is using discrete oscilator for DP (27MHz) and si5332 for other clocks but clocks are different compare to kv260 that's why fix it to aligned with the latest schematics. On the other handle kr260 revB/revA03 also contains 74.25 MHz discrete clock chip for SLVC-EC output which is not defined.
