spi: Tesla FSD support 

Merge series from Alim Akhtar:

This series adds support for the SPI controller in the Tesla FSD SoC,
also pulling in:

   git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd.git ib-mfd-spi-dt-v5.18

from the MFD tree which has dependencies for the DT bindings.

Maxim MAX14577/77836 Multi-Function Device



MAX14577 is a Multi-Function Device with Micro-USB Interface Circuit, Li+

Battery Charger and SFOUT LDO output for powering USB devices. It is

interfaced to host controller using I2C.



MAX77836 additionally contains PMIC (with two LDO regulators) and Fuel Gauge.

For the description of Fuel Gauge low SOC alert interrupt see:

../power/supply/max17040_battery.txt





Required properties:

- compatible : Must be "maxim,max14577" or "maxim,max77836".

- reg : I2C slave address for the max14577 chip (0x25 for max14577/max77836)

- interrupts : IRQ line for the chip.





Required nodes:

 - charger :

	Node for configuring the charger driver.

	Required properties:

		- compatible : "maxim,max14577-charger"

			or "maxim,max77836-charger"

		- maxim,fast-charge-uamp : Current in uA for Fast Charge;

			Valid values:

			- for max14577: 90000 - 950000;

			- for max77836: 45000 - 475000;

		- maxim,eoc-uamp : Current in uA for End-Of-Charge mode;

			Valid values:

			- for max14577: 50000 - 200000;

			- for max77836: 5000 - 100000;

		- maxim,ovp-uvolt : OverVoltage Protection Threshold in uV;

			In an overvoltage condition, INT asserts and charging

			stops. Valid values:

			- 6000000, 6500000, 7000000, 7500000;

		- maxim,constant-uvolt : Battery Constant Voltage in uV;

			Valid values:

			- 4000000 - 4280000 (step by 20000);

			- 4350000;





Optional nodes:

- max14577-muic/max77836-muic :

	Node used only by extcon consumers.

	Required properties:

		- compatible : "maxim,max14577-muic" or "maxim,max77836-muic"



- regulators :

	Required properties:

		- compatible : "maxim,max14577-regulator"

			or "maxim,max77836-regulator"



	May contain a sub-node per regulator from the list below. Each

	sub-node should contain the constraints and initialization information

	for that regulator. See regulator.txt for a description of standard

	properties for these sub-nodes.



	List of valid regulator names:

	- for max14577: CHARGER, SAFEOUT.

	- for max77836: CHARGER, SAFEOUT, LDO1, LDO2.



	The SAFEOUT is a fixed voltage regulator so there is no need to specify

	voltages for it.





Example:



#include <dt-bindings/interrupt-controller/irq.h>



max14577@25 {

	compatible = "maxim,max14577";

	reg = <0x25>;

	interrupts = <5 IRQ_TYPE_LEVEL_LOW>;



	muic: max14577-muic {

		compatible = "maxim,max14577-muic";

	};



	regulators {

		compatible = "maxim,max14577-regulator";



		SAFEOUT {

		};

		CHARGER {

			regulator-name = "CHARGER";

			regulator-min-microamp = <90000>;

			regulator-max-microamp = <950000>;

			regulator-boot-on;

Maxim MAX77802 multi-function device



The Maxim MAX77802 is a Power Management IC (PMIC) that contains 10 high

efficiency Buck regulators, 32 Low-DropOut (LDO) regulators used to power

up application processors and peripherals, a 2-channel 32kHz clock outputs,

a Real-Time-Clock (RTC) and a I2C interface to program the individual

regulators, clocks outputs and the RTC.



Bindings for the built-in 32k clock generator block and

regulators are defined in ../clk/maxim,max77802.txt and

../regulator/max77802.txt respectively.



Required properties:

- compatible		: Must be "maxim,max77802"

- reg			: Specifies the I2C slave address of PMIC block.

- interrupts		: I2C device IRQ line connected to the main SoC.



Example:



	max77802: pmic@9 {

		compatible = "maxim,max77802";

		interrupt-parent = <&intc>;

		interrupts = <26 IRQ_TYPE_NONE>;

		reg = <0x09>;
