- Qualcomm Technologies Inc Blackghost(BG) PIL driver:
- Blackghost(BG) PIL driver provide interface to load and boot Blackghost(BG)
- SOC. Blackghost(BG) SOC is an external SOC which communicate to MSM via
- SPI. The PIL driver loads firmware into memory and invoke secure app via
- qseecom to transfer and handshake the boot process. Once Blackghost(BG) SOC
- is booted it raises ready interrupt which is handled by BG PIL driver, and
- this event is informed to other MSM drivers, other remote subsystem via
- notifier framework. The PIL driver also handles interrupt for the BG SOC
- crash upon arrival of which it reset and initiates ramdump collection for BG
- SOC.
- Required properties:
- - compatible: Must be "qcom,PIL-blackghost"
- - qcom,firmware-name: Base name of the firmware image.
- - qcom,bg2ap-status-gpio: GPIO used by the blackghost to indicate status to the apps.
- - qcom,bg2ap-errfatal-gpio: GPIO used by the blackghost to indicate software error to the apps.
- - qcom,ap2bg-status-gpio: GPIO used by the apps to indicate its status to blackghost.
- - qcom,ap2bg-errfatal-gpio: GPIO used by the apps to indicate blackghost about apps reset.
- Example:
- qcom,blackghost {
- compatible = "qcom,pil-blackghost";
- qcom,firmware-name = "bgelf";
- /* GPIO inputs from blackghost */
- qcom,bg2ap-status-gpio = <&msm_gpio 97 0>;
- qcom,bg2ap-errfatal-gpio = <&msm_gpio 95 0>;
- /* GPIO output to blackghost */
- qcom,ap2bg-status-gpio = <&msm_gpio 17 0>;
- qcom,ap2bg-errfatal-gpio = <&msm_gpio 23 0>;
- };
