| Qualcomm MSS QDSP6v5 Peripheral Image Loader |
| |
| pil-qdsp6v5-mss is a peripheral image loader (PIL) driver. It is used for |
| loading QDSP6v5 (Hexagon) firmware images for modem subsystems into memory and |
| preparing the subsystem's processor to execute code. It's also responsible for |
| shutting down the processor when it's not needed. |
| |
| Required properties: |
| - compatible: Must be "qcom,pil-q6v5-mss" |
| - reg: Pairs of physical base addresses and region sizes of |
| memory mapped registers. |
| - reg-names: Names of the bases for the above registers. "qdsp6_base", |
| "halt_base", "rmb_base", "restart_reg", and |
| "metadata_base" are expected. |
| - interrupts: The modem watchdog interrupt |
| - vdd_mss-supply: Reference to the regulator that supplies the processor. |
| - vdd_cx-supply: Reference to the regulator that supplies the vdd_cx domain. |
| - vdd_mx-supply: Reference to the regulator that supplies the memory rail. |
| - qcom,firmware-name: Base name of the firmware image. Ex. "mdsp" |
| - qcom,pil-self-auth: <0> if the hardware does not require self-authenticating |
| images and self-authentication is not desired; |
| <1> if the hardware requires self-authenticating images. |
| - qcom,is-loadable: if PIL is required to load the modem image |
| |
| Optional properties: |
| - vdd_pll-supply: Reference to the regulator that supplies the PLL's rail. |
| - qcom,vdd_pll: Voltage to be set for the PLL's rail. |
| |
| Example: |
| qcom,mss@fc880000 { |
| compatible = "qcom,pil-q6v5-mss"; |
| reg = <0xfc880000 0x100>, |
| <0xfd485000 0x400>, |
| <0xfc820000 0x020>, |
| <0xfc401680 0x004>, |
| <0x0d1f0000 0x4000>; |
| reg-names = "qdsp6_base", "halt_base", "rmb_base", |
| "restart_reg", metadata_base"; |
| interrupts = <0 24 1>; |
| vdd_mss-supply = <&pm8841_s3>; |
| vdd_cx-supply = <&pm8841_s2>; |
| vdd_mx-supply = <&pm8841_s1>; |

| qcom,is-loadable; |
| qcom,firmware-name = "mba"; |
| qcom,pil-self-auth = <1>; |
