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.

+ bool "Google Firmware Drivers"
+ default n
+ help
+ These firmware drivers are used by Google servers,
+ Chromebooks and other devices using coreboot firmware.
+ If in doubt, say "N".

+config GOOGLE_SMI
+ tristate "SMI interface for Google platforms"
+ depends on X86 && ACPI && DMI
+ help
+ Say Y here if you want to enable SMI callbacks for Google
+ platforms. This provides an interface for writing to and
+ clearing the event log. If CONFIG_EFI is also enabled this
+ driver provides an interface for reading and writing NVRAM
+ variables.
+
+config GOOGLE_CBMEM
+ tristate "CBMEM entries in sysfs"
+ depends on GOOGLE_COREBOOT_TABLE
+ help
+ CBMEM is a downwards-growing memory region created by the
+ Coreboot BIOS containing tagged data structures from the
+ BIOS. These data structures expose things like the verified
+ boot firmware variables, flash layout, firmware event log,
+ and more.
+
+ This option enables the cbmem module, which causes the
+ kernel to search for Coreboot CBMEM entries, and expose the
+ memory for each entry in sysfs under
+ /sys/bus/coreboot/devices/cbmem-<id>.
+
+config GOOGLE_COREBOOT_TABLE
+ tristate "Coreboot Table Access"
+ depends on HAS_IOMEM && (ACPI || OF)
+ help
+ This option enables the coreboot_table module, which provides other
+ firmware modules access to the coreboot table. The coreboot table
+ pointer is accessed through the ACPI "GOOGCB00" object or the
+ device tree node /firmware/coreboot.
+ If unsure say N.

+ help
+ This option enables the kernel to search for a firmware log in

+ userland in the file /sys/firmware/log.
+
+config GOOGLE_FRAMEBUFFER_COREBOOT
+ tristate "Coreboot Framebuffer"
+ depends on GOOGLE_COREBOOT_TABLE
+ help
+ This option enables the kernel to search for a framebuffer in
+ the coreboot table. If found, it is registered with a platform
+ device of type coreboot-framebuffer. Using the old device of
+ type simple-framebuffer is deprecated.
+
+config GOOGLE_MEMCONSOLE_COREBOOT
+ tristate "Firmware Memory Console"
