ARM: driver updates for 6.1

Browse Source 
The drivers branch for 6.1 is a bit larger than for most releases.  Most
 of the changes come from SoC maintainers for the drivers/soc subsystem:
 
  - A new driver for error handling on the NVIDIA Tegra
    'control backbone' bus.
 
  - A new driver for Qualcomm LLCC/DDR bandwidth measurement
 
  - New Rockchip rv1126 and rk3588 power domain drivers
 
  - DT binding updates for memory controllers, older Rockchip
    SoCs, various Mediatek devices, Qualcomm SCM firmware
 
  - Minor updates to Hisilicon LPC bus, the Allwinner SRAM
    driver, the Apple rtkit firmware driver, Tegra firmware
 
  - Minor updates for SoC drivers (Samsung, Mediatek, Renesas,
    Tegra, Qualcomm, Broadcom, NXP, ...)
 
 There are also some separate subsystem with downstream maintainers that
 merge updates this way:
 
  - Various updates and new drivers in the memory controller
    subsystem for Mediatek and Broadcom SoCs
 
  - Small set of changes in preparation to add support for FF-A
    v1.1 specification later, in the Arm FF-A firmware subsystem
 
  - debugfs support in the PSCI firmware subsystem

assorted actions.

* "qcom,scm-sm8250"
* "qcom,scm-sm8350"
* "qcom,scm-sm8450"
and:
* "qcom,scm"
- clocks: Specifies clocks needed by the SCM interface, if any:
* core clock required for "qcom,scm-apq8064", "qcom,scm-msm8660" and
"qcom,scm-msm8960"
* core, iface and bus clocks required for "qcom,scm-apq8084",
"qcom,scm-msm8916", "qcom,scm-msm8953", "qcom,scm-msm8974" and "qcom,scm-msm8976"
- clock-names: Must contain "core" for the core clock, "iface" for the interface
clock and "bus" for the bus clock per the requirements of the compatible.
- qcom,dload-mode: phandle to the TCSR hardware block and offset of the
download mode control register (optional)
- interconnects: Specifies the bandwidth requirements of the SCM interface (optional)
Example for MSM8916:

* Samsung Exynos5 G-Scaler device
G-Scaler is used for scaling and color space conversion on Exynos5 SoCs.
Required properties:
- compatible: should be one of
"samsung,exynos5250-gsc"
"samsung,exynos5420-gsc"
"samsung,exynos5433-gsc"
"samsung,exynos5-gsc" (deprecated)
- reg: should contain G-Scaler physical address location and length.
- interrupts: should contain G-Scaler interrupt number
Optional properties:
- samsung,sysreg: handle to syscon used to control the system registers to
set writeback input and destination
Example:
gsc_0: gsc@13e00000 {
compatible = "samsung,exynos5250-gsc";
reg = <0x13e00000 0x1000>;
interrupts = <0 85 0>;
};
Aliases:
Each G-Scaler node should have a numbered alias in the aliases node,
in the form of gscN, N = 0...3. G-Scaler driver uses these aliases
to retrieve the device IDs using "of_alias_get_id()" call.
Example:
aliases {
gsc0 =&gsc_0;
gsc1 =&gsc_1;
gsc2 =&gsc_2;
gsc3 =&gsc_3;
};

Synopsys DesignWare Enhanced uMCTL2 DDR Memory Controller is capable of
working with the memory devices supporting up to (LP)DDR4 protocol. It can
be equipped with SEC/DEC ECC feature if DRAM data bus width is either
16-bits or 32-bits or 64-bits wide.
For instance the ZynqMP DDR controller is based on the DW uMCTL2 v2.40a
controller. It has an optional SEC/DEC ECC support in 64- and 32-bits
bus width configurations.

The System Reset Controller (SRC) is responsible for the generation of
all the system reset signals and boot argument latching.
Its main functions are as follows,
- Deals with all global system reset sources from other modules,
and generates global system reset.
- Responsible for power gating of MIXs (Slices) and their memory
low power control.
