Subject: [PATCH v6 0/9] Improve MCP3911 driver

This patch series intend to fix bugs and improve functionality of the MCP3911 driver.
The main features added are
- Support for buffers
- Interrupt driven readings
- Support for oversampling ratio
- Support for set scale values (Gain)

Among the bug fixes, there are changes in the formula for calculate raw value and a fix for mismatch in the devicetree property.

Another general improvement for the driver is to use managed resources for all allocated resources.

See patch notes for more specific changes.

General changes for the series:

v3:
- Drop Phase patch
- Add Fixes tags for those patches that are fixes
- Move Fixes patches to the beginning of the patchset

v4:
- Split up devm-cleanup functions 
- Cosmetic cleanups
- Add
	select IIO_BUFFER
	select IIO_TRIGGERED_BUFFER
    To Kconfig
- Add .endianness = IIO_BE

v5:
- Drop remove function
- Split tx&rx transfers in mcp3911_trigger_handler()
- Moved Kconfig changes to right patch

v6:
- Go for devm_clk_get_enabled()
- Cosmetic cleanups
- Clarify the description of microchip,data-ready-hiz
