Kernel interface for battery controls

Are there any plans to add support for interacting with the battery controls in the Dell kernel driver (analog to the [implementation in libsmbios](https://github.com/dell/libsmbios/commit/0eab0085e8f0db3c2a0f8ae0146d3352c40d785a), just in the kernel)?

As I have outlined already in an issue for the [TLP utility](https://github.com/linrunner/TLP) (https://github.com/linrunner/TLP/issues/321#issuecomment-575653531 and https://github.com/linrunner/TLP/issues/321#issuecomment-576059832), Google has introduced a set of new sysfs attributes and infrastructure that makes it fairly easy to implement extended controls for power supplies, and in particular batteries (for details see [Documentation/ABI/testing/sysfs-class-power](https://github.com/torvalds/linux/blob/26dca6dbd62d74a5012cafab6b2d6d65a01ea69c/Documentation/ABI/testing/sysfs-class-power#L156) and [drivers/power/supply/power_supply_sysfs.c](https://github.com/torvalds/linux/blob/26dca6dbd62d74a5012cafab6b2d6d65a01ea69c/drivers/power/supply/power_supply_sysfs.c#L239)).

This appears to be primarily aimed at their new Embedded Controller (Wilco EC) on the chromebook platform ([drivers/power/supply/wilco-charger.c](https://github.com/torvalds/linux/blob/26dca6dbd62d74a5012cafab6b2d6d65a01ea69c/drivers/power/supply/wilco-charger.c) and [Documentation/ABI/testing/sysfs-class-power-wilco](https://github.com/torvalds/linux/blob/26dca6dbd62d74a5012cafab6b2d6d65a01ea69c/Documentation/ABI/testing/sysfs-class-power-wilco)), but in particular the [charge modes](https://github.com/torvalds/linux/blob/26dca6dbd62d74a5012cafab6b2d6d65a01ea69c/drivers/power/supply/wilco-charger.c#L24) and [battery charging threshold settings in custom mode](https://github.com/torvalds/linux/blob/26dca6dbd62d74a5012cafab6b2d6d65a01ea69c/drivers/power/supply/wilco-charger.c#L118) of the Wilco EC map directly to the ones found in [Dell laptops](https://github.com/dell/libsmbios/commit/0eab0085e8f0db3c2a0f8ae0146d3352c40d785a#diff-edb5764dc20eb3b3ec617b1bf3cce546R113).

Support for [Huawei](https://github.com/torvalds/linux/commit/355a070b09ab1f29f36447c91cde3e6fd07775e0) and [Asus](https://github.com/torvalds/linux/commit/7973353e92ee1e7ca3b2eb361a4b7cb66c92abee) laptops to use this new sysfs interface has also been implemented, and the [Lenovo](https://sourceforge.net/p/ibm-acpi/mailman/message/36911999/) driver may also be ported over soon.

Last, if there is a better place to report feature request for the Dell laptop driver in the Linux kernel, I would appreciate if someone could direct to the right place/forum for that.
