Merge branch 'i2c/for-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux 

Pull i2c updates from Wolfram Sang:

 - mostly driver updates. Bigger ones for mlxcpld and iproc. But most of
   them are all over the place.

 - removal of the efm32, sirf, u300, and zte zx bus drivers because of
   platform removal. So, we have a pleasant diffstat this time.

 - first set of cleanups in the I2C core as preparation to increase
   maximum length of SMBus transfers to 255 (as specified in the new
   standard). Better documentation of struct i2c_msg and its flags stand
   out here.

 - the testunit can now respond to SMBus block process calls which is
   the testcase when implementing the above new maximum length.

I2C for SiRFprimaII platforms



Required properties :

- compatible : Must be "sirf,prima2-i2c"

- reg: physical base address of the controller and length of memory mapped

     region.

- interrupts: interrupt number to the cpu.



Optional properties:

- clock-frequency : Constains desired I2C/HS-I2C bus clock frequency in Hz.

  The absence of the property indicates the default frequency 100 kHz.



Examples :



i2c0: i2c@b00e0000 {

    compatible = "sirf,prima2-i2c";

    reg = <0xb00e0000 0x10000>;

    interrupts = <24>;

- #address-cells = <1>;

- #size-cells = <0>;

ZTE zx2967 I2C controller



Required properties:

 - compatible: must be "zte,zx296718-i2c"

 - reg: physical address and length of the device registers

 - interrupts: a single interrupt specifier

 - clocks: clock for the device

 - #address-cells: should be <1>

 - #size-cells: should be <0>

 - clock-frequency: the desired I2C bus clock frequency.



Examples:



	i2c@112000 {

		compatible = "zte,zx296718-i2c";

		reg = <0x00112000 0x1000>;

		interrupts = <GIC_SPI 112 IRQ_TYPE_LEVEL_HIGH>;
