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 a293ec25d59d Merge tag 'linux_kselftest-fixes-7.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest of Mainline Linux. Series has been tested on the following boards: 1. AM642-SK https://gist.github.com/Siddharth-Vadapalli-at-TI/c9f644dda67a122d3299569b2a0214ab 2.
