Subject: dt-bindings: Add bindings for Tegra234 Host1x and VIC
X-Git-Tag: v6.1-rc5~617^2~14^2~25
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5c5a6ff72e193302b21fd4c2afc6bd8cc26f68e2;p=platform%2Fkernel%2Flinux-starfive.git

dt-bindings: Add bindings for Tegra234 Host1x and VIC

Update VIC and Host1x bindings for changes in Tegra234.

Namely,
- New compatible strings
- Sharded syncpoint interrupts
- Optional reset.

Also, fix the order of descriptions for VM/hypervisor
register apertures -- while the reg-names specification
was correct, the descriptions for these were switched.
