	Macros can be confusing on their own; hiding commas make things worse. This can sometimes be downright misleading. A "good" example would be the code in soc/intel/xeon_sp/spr/chip.c: CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev, This appears as CHIP_NAME() being some struct when in fact these are defining 2 separate members of the same struct. It was decided to remove this macro altogether, as it does not do anything special and incurs a maintenance burden.

	This adds a driver for the ITE IT5570E EC in combination with Clevo vendor EC firmware. The interface is mostly identical on various laptop models. Thus, we have implemented one common driver to support them all. The following features were implemented: - Basics like battery, ac, etc. - Suspend/hibernate support: S0ix, S3, S4/S5 - Save/restore of keyboard backlight level during S0ix without the need for Clevo vendor software (ControlCenter) - Flexicharger - Fn keys (backlight, volume, airplane etc.) - Various configuration options via Kconfig / CMOS options Note: S3 support works at least on L140CU (Cometlake), but it's not enabled for this board because S0ix is used. Not implemented, yet: - Type-C UCSI: the EC firmware seems to be buggy (with vendor fw, too) - dGPU support is WIP An example of how this driver can be hooked up by a board can be seen in in change CB:59850, where support for the L140MU is added. Known issues: - Touchpad toggle: The touchpad toggle (Fn-F1) has two modes, Ctrl-Alt-F9 mode and keycodes 0xf7/0xf8 mode. Ctrl-Alt-F9 is the native touchpad toggle shortcut on Windows. On Linux this would switch to virtual console 9, if enabled. Thus, one should use the keycodes mode and add udev rules as specified in [1]. If VT9 is disabled, Ctrl-Alt-F9 mode could be used to set up a keyboard shortcut command toggling the touchpad. - Multi-fan systems The Clevo NV41MZ (w/o dGPU) has two fans that should be in-sync. However, the second fan does not spin. This needs further investigation. [1] https://docs.dasharo.com/variants/clevo_nv41/post_install/ Testing the various functionalities of this EC driver was done in the changes hooking up this driver for the boards.
