Subject: dt-bindings: timestamp: Add Tegra264 support
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=d354e47f6464bddd777916f3939bafa1673156c7;p=thirdparty%2Fkernel%2Flinux.git

dt-bindings: timestamp: Add Tegra264 support

Add timestamp provider support for the Tegra264 in devicetree
bindings. Tegra264 has two generic timestamping engines (GTE)
which are the always-on GTE (AON) and legacy interrupt
controller (LIC) GTE.
'nvidia,slices' property is deprecated and hence not allowed for
Tegra264.
