Subject: [PATCH v1 0/1] rtc: zynqmp: ensure correct RTC calibration
Date: Mon, 4 Aug 2025 15:47:49 +0000 [thread overview]
Message-ID: <20250804154750.28249-1-l.rubusch@gmail.com> (raw)
We've observed intermittent failures with the current implementation on our
Xilinx hardware. These issues were not present prior to the commit
referenced by the Fixes tag, using the same hardware setup. The problem
appears to be identical to the one described here:
https://adaptivesupport.amd.com/s/article/000036886?language=en_US
Instead of explicitly writing 0x7FFF to the calibration register using
devmem, the patch now resets the register.
