  * Drop compatible properties.
* Patch 2: "regulator: max77541: Add ADI MAX77541/MAX77540 Regulator Support"
  * Change if-else ladder to switch case for chip->id
  * Drop driver_data in platform_device_id
* Patch 3: "iio: adc: : max77541 Add ADI MAX77541 ADC Support"
  * Drop max77541_adc_iio struct
* Patch 4: "dt-bindings: mfd: max77541: adi,max77541.yaml Add MAX77541 bindings"
  * Drop allOf
* Patch 5: "mfd: max77541: Add MAX77541/MAX77540 PMIC Support"
  * Dont use compatible when using MFD_CELL_OF MACRO

Changes in v4:
* Patch 1: "dt-bindings: regulator: Add ADI MAX77541/MAX77540 Regulator"
  * NO CHANGE
* Patch 2: "drivers: regulator: Add ADI MAX77541/MAX77540 Regulator Support"
  * Drop OF ID Table

  * Add missing blank line
* Patch 4: "dt-bindings: mfd: adi,max77541.yaml Add MAX77541 bindings"
  * NO CHANGE(Order of patchset changed, and [4/5] has dependency to [1/5])
* Patch 5: "drivers: mfd: Add MAX77541/MAX77540 PMIC Support"
  * Use pointers in the driver_data
  * Use probe_new instead of probe

Changes in v3:
* Patch 1: "drivers: mfd: Add ADI MAX77541/MAX77540 PMIC Support"
  * Change struct name from max77541_dev to max77541
  * Adjust max-line-length lower than 80
* Patch 2: "dt-bindings: mfd: Add ADI MAX77541/MAX77540"
  * Remove adc object as we do not need
  * Remove adc node from example
* Patch 3: "drivers: regulator: Add ADI MAX77541/MAX77540 Regulator Support"
  * Change node name from "BUCK#_id" to "buck#_id" in regulator desc
* Patch 4: "dt-bindings: regulator: Add ADI MAX77541/MAX77540 Regulator"
  * Change node name from "BUCK" to "buck" in regulators
* Patch 5: "drivers: iio: adc: Add ADI MAX77541 ADC Support"
  * Convert voltage values from V to mV for scaling.
  * Convert temperature values from C to miliC for scale and offset
  * Do not set offset bit in info_mask_separate for voltage that does not need offset
  * Remove unnecessary dev_get_drvdata() instead of it use dev_get_regmap to have regmap.
  * Assing hard coded name for adc dev name

Changes in v2:
* Patch 1: "drivers: mfd: Add MAX77541/MAX77540 PMIC Support"
  * Drop "this patch adds" from commit message.
  * Drop redundant blank lines.
  * Drop module version
  * Use definition for parameter of devm_mfd_add_devices(.., -1,..)
  * Use desc in chip_info to adding desc for different devices.
  * Add missing headers and forward declarations.
  * Drop unused elements from max77541_dev struct
  * Add chip_info into max77541_dev struct to identify different devices.
* Patch 2: "dt-bindings: mfd: adi,max77541.yaml Add MAX77541 bindings"
  * Drop "this patch adds" from commit message.
  * Fix $ref path
  * Drop adc part under allOf
  * Keep only one example (more complex one)
  * Fix make dt_binding_check errors.(trailing space, No newline)
* Patch 3: "drivers: regulator: Add MAX77541 Regulator Support"
  * Drop "this patch adds" from commit message.
  * Add trailing comma for required structs.
  * Fix wrong indentation.
  * Drop redundant blank lines.
  * Drop max77541_regulator_dev struct.
  * Use "regulator_desc *desc" for both regulator
    regarding to "max77541->id"
* Patch 4: "dt-bindings: regulator: max77541-regulator.yaml Add MAX77541
            Regulator bindings"
  * Drop "this patch adds" from commit message.
  * Chance filename (matching compatible), so adi,max77541-regulator.yaml
  * Fix make dt_binding_check errors.(trailing space, No newline)
* Patch 5: "drivers: iio: adc: Add MAX77541 ADC Support"
  * Drop "this patch adds" from commit message.
  * Drop redundant blank lines.
  * Fix wrong include path.
  * Use switch instead of if-else for range setting in max77541_adc_scale
  * Move max77541_adc_range enum from max77541.h to here.
