^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  1) Palmas RTC controller bindings
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) Required properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) - compatible:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5)   - "ti,palmas-rtc" for palma series of the RTC controller
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) - interrupts: Interrupt number of RTC submodule on device.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) Optional properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) - ti,backup-battery-chargeable: The Palmas series device like TPS65913 or
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 	TPS80036 supports the backup battery for powering the RTC when main
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 	battery is removed or in very low power state. The backup battery
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 	can be chargeable or non-chargeable. This flag will tells whether
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 	battery is chargeable or not. If charging battery then driver can
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 	enable the charging.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) - ti,backup-battery-charge-high-current: Enable high current charging in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) 	backup battery. Device supports the < 100uA and > 100uA charging.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 	The high current will be > 100uA. Absence of this property will
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 	charge battery to lower current i.e. < 100uA.
