Extensions - not fully tested

Here you can find additional patches for regulator run-level and LED control as well as for charger/fuel-gauge support. Please see the branch stable-v5.4.6. Keep in mind that some GPIO/regulator features have been backported to this stable kernel and no full testing has been performed - you should be prepared to do testing and fixing as needed. Please treat these changes as a implementation reference only.

Configuration options may want to enable are:

* CONFIG_MFD_ROHM_BD71828 for BD71828 core
* CONFIG_REGULATOR_BD71828 for regulator control
* CONFIG_COMMON_CLK_BD718XX for clock gate control
* CONFIG_GPIO_BD71828 for GPIO control
* CONFIG_RTC_DRV_BD70528 for RTC control

Configuration options for out of tree drivers:
* CONFIG_POWER_BD71828
