The CONFIG_HPET_MMAP Kconfig option exposes the memory map of the HPET registers to userspace. The Kconfig help points out that in some cases this can be a security risk as some systems may erroneously configure the map such that additional data is exposed to userspace. This is a problem for

[PATCH 1/7] ARM: tegra: finalize USB EHCI and PHY bindings

The existing Tegra USB bindings have a few issues: 1) Many properties are documented as being part of the EHCI controller node, yet they apply more to the PHY device. They should be moved. 2) Some registers in PHY1 are shared with PHY3, and hence PHY3 needs a reg entry to point at PHY1's
