This is mandated by the USB Specification section 6.5.3 Normative Spread Spectrum Clocking (SSC). Series has been posted as individual patches for respective boards since the Fixes tag is different for each board and needs to be backported via stable. Series is based on commit 74fe02ce122a Merge tag 'wq-for-7.1-rc2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq of Mainline Linux. v1 of this series is at: https://lore.kernel.org/r/20260505110631.1144200-1-s-vadapalli@ti.com/ Changes since v1: - Collected Acked-by tag on patch 1 from Josua Mayer - Reordered properties in patches 7, 8, 12 and 13 to have 'status' at the end of the node based on feedback from Francesco Dolcini Series has been tested on the following boards: 1.
