Month: 2025-12 — Summary of work on flipperdevices/u-boot focused on stability and SDHCI reliability. Implemented a DLL control hook to disable the core DLL when the bus clock is at or below 100 MHz, improving stability and performance in the MSM SDHCI driver. The change includes an SDHCI ops hook (config_dll) and a minimal DLL control routine, aligning with upstream Linux MSM SDHCI behavior. Patch is submitted with a full Signed-off-by chain and references upstream patch link, demonstrating adherence to kernel development practices. This work reduces low-clock instability in the MMC/SD subsystem and contributes to more reliable boot-time and device operation across affected platforms.
