Input: tsc2007 - read "ti,poll-period" as u32grafted
The "ti,poll-period" property is documented as a normal uint32 cell. The driver used a u64 helper, which makes the helper type disagree with the schema even though the stored value is still small. Read "ti,poll-period" with the u32 helper matching the documented DT cell size.

+Memory Management
+=================
+
+Linux memory management subsystem is responsible, as the name implies,
+for managing the memory in the system. This includes implementation of
+virtual memory and demand paging, memory allocation both for kernel
+internal structures and user space programs, mapping of files into
+processes address space and many other cool things.
+
+Linux memory management is a complex system with many configurable
+settings. Most of these settings are available via ``/proc``
+filesystem and can be queried and adjusted using ``sysctl``. These APIs
+are described in Documentation/admin-guide/sysctl/vm.rst and in `man 5 proc`_.
+
+.. _man 5 proc: http://man7.org/linux/man-pages/man5/proc.5.html
+
+Linux memory management has its own jargon and if you are not yet
+familiar with it, consider reading Documentation/admin-guide/mm/concepts.rst.
+
+Here we document in detail how to interact with various mechanisms in
+the Linux memory management.
