Subject: [PATCH 00/13] TI: K3 DTS: fix USB Clocking for Compliance
Date: Tue, 5 May 2026 16:36:01 +0530 [thread overview]
Message-ID: <20260505110631.1144200-1-s-vadapalli@ti.com> (raw)
Hello,
This series enables Internal Spread Spectrum Clocking (SSC) for USB
SuperSpeed configuration. 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
