Merge tag 'tegra-for-6.16-dt-bindings' of https://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into soc/dt

Device tree bindings updates for v6.16-rc1

Convert the legacy interrupt controller (LIC) and APBDMA controller
device tree bindings from freeform text to dt-schema.

Document the ASUS Transformer Pad TF300TL compatible string and add
missing compatible strings for newer generations of the Tegra CEC.

-NVIDIA Legacy Interrupt Controller
-
-All Tegra SoCs contain a legacy interrupt controller that routes
-interrupts to the GIC, and also serves as a wakeup source. It is also
-referred to as "ictlr", hence the name of the binding.
-
-The HW block exposes a number of interrupt controllers, each
-implementing a set of 32 interrupts.
-
-Required properties:
-
-- compatible : should be: "nvidia,tegra<chip>-ictlr". The LIC on
-  subsequent SoCs remained backwards-compatible with Tegra30, so on
-  Tegra generations later than Tegra30 the compatible value should
-  include "nvidia,tegra30-ictlr".	
-- reg : Specifies base physical address and size of the registers.
-  Each controller must be described separately (Tegra20 has 4 of them,
-  whereas Tegra30 and later have 5).
-- interrupt-controller : Identifies the node as an interrupt controller.
-- #interrupt-cells : Specifies the number of cells needed to encode an
-  interrupt source. The value must be 3.
-
-Notes:
-
-- Because this HW ultimately routes interrupts to the GIC, the
-  interrupt specifier must be that of the GIC.
-- Only SPIs can use the ictlr as an interrupt parent. SGIs and PPIs
-  are explicitly forbidden.
-
-Example:
-
-	ictlr: interrupt-controller@60004000 {
-		compatible = "nvidia,tegra20-ictlr", "nvidia,tegra-ictlr";
-		reg = <0x60004000 64>,
-		      <0x60004100 64>,
-		      <0x60004200 64>,
-		      <0x60004300 64>;
-		interrupt-controller;
-		#interrupt-cells = <3>;
-		interrupt-parent = <&intc>;
-	};
