The RAA215300 is a high Performance 9-Channel PMIC supporting DDR Memory, with Built-In Charger and RTC. It supports DDR3, DDR3L, DDR4, and LPDDR4 memory power requirements. The internally compensated regulators, built-in Real-Time Clock (RTC), 32kHz crystal oscillator, and coin cell battery charger provide a highly integrated, small footprint power solution ideal for System-On-Module (SOM) applications. A spread spectrum feature provides an ease-of-use solution for noise-sensitive audio or RF applications. Signed-off-by: Biju Das --- v2->v3: * Added more detailed description for renesas,rtc-enabled property. RFC->v2: * Updated reg property * Added optional reg-names, interrupts and renesas,rtc-enabled properties. * Fixed the node name in the example * Dropped the cross link property renesas,raa215300-rtc. * Updated the example --- .../bindings/mfd/renesas,raa215300.yaml | 70 +++++++++++++++++++ 1 file changed, 70 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/renesas,raa215300.yaml diff --git a/Documentation/devicetree/bindings/mfd/renesas,raa215300.yaml b/Documentation/devicetree/bindings/mfd/renesas,raa215300.yaml new file mode 100644 index 000000000000..04d34e5be23e --- /dev/null +++ b/Documentation/devicetree/bindings/mfd/renesas,raa215300.yaml @@ -0,0 +1,70 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/mfd/renesas,raa215300.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Renesas RAA215300 Power Management Integrated Circuit (PMIC) + +maintainers: + - Biju Das + +description: | + The RAA215300 is a high-performance, low-cost 9-channel PMIC designed for + 32-bit and 64-bit MCU and MPU applications.
