| * Qualcomm Connectivity SubSystem Platform Driver |
| |
| This platform driver adds support for the CNSS subsystem used for SDIO |
| based Wi-Fi devices. It also adds support to manage two 1.8V voltage |
| regulators and WLAN power enable 3.3V regulators. The main purpose of this |
| device tree entry below is to invoke the CNSS SDIO platform driver |
| and provide handle to the WLAN power enable 3.3V pmic GPIO and two 1.8V |
| PMIC voltage regulator resources. |
| |
| Required properties: |
| - compatible: "qcom,cnss_sdio" |
| - reg: memory resource to save firmware dump, optional. |
| - reg-names: memory resource name. |
| - subsys-name: cnss sdio subsytem device name, required. |
| - vdd-wlan-supply: phandle to the WLAN vdd regulator device tree node. |
| - vdd-wlan-dsrc-supply: phandle to the WLAN dsrc vdd regulator device tree node. |
| - vdd-wlan-io-supply: phandle to the WLAN IO regulator device tree node. |
| - vdd-wlan-xtal-supply: phandle to the WLAM XTAL regulator device tree node. |
| |
| Optional properties: |
| - pinctrl-names: Names corresponding to the numbered pinctrl states |
| - pinctrl-<n>: Pinctrl states as described in |
| bindings/pinctrl/pinctrl-bindings.txt |
| - qcom,is-antenna-shared: Enabled for Platforms with both sdio and pcie QCA |
| Chipsets are attached. |
| - qcom,cnss-enable-bus-bandwidth: define this property when target support to |
| vote for bus bandwidth. |
| - qcom,msm-bus,name: client name for msm bus register. |
| - qcom,msm-bus,num-cases: number of cases for bus scaling. |
| - qcom,msm-bus,num-paths: number of paths for bus scale vector. |
| - qcom,msm-bus,vectors-KBps: bus scale vector table. |
| |
