| Qualcomm Femtocell (FSM99XX and FSM90XX) Peripheral Image Loader |
| |
| pil-femto-modem is a peripheral image loader (PIL) driver. It is used for |
| loading firmware images on multiple modems resident on the FSM99XX and |
| FSM90XX platforms. |
| |
| The top-level device tree entry has the following properties: |
| |
| Required properties: |
| - compatible: Must be "qcom,pil-femto-modem". |
| - reg: Pair of physical base address and region size of the |
| QDSP6[0] control registers. |
| - reg-names: "qdsp6_base" is required. |
| - qcom,firmware-name: Base name of the MBA firmware image ("mba"). |
| Maximum size is 4 characters. |
| - qcom,max-num-modems: Number of modem child nodes specified. |
| |
| Optional properties: |
| - qcom,q6-freq-row: Row number from the frequency table. Must be specified |
| with qcom,q6-freq-col. Refer to MBA documentation for |
| specifics on frequency table row selection. Current |
| row maximum is 6. |
| - qcom,q6-freq-col: The column numbers from the frequency table. This must |
| be specified if qcom,q6-freq-row is specified. The |
| number of column values corresponds to the number of |
| QDSPs available, and each selection corresponds to a |
| desired frequency. Refer to MBA documentation for |
| specifics on frequency table column selections when |
| paired with a given row. Current column maximum is 7. |
| |
| One child node per modem that must be loaded is required. |
| |
| Required properties: |
| - compatible: Must be "qcom,pil-femto-modem-desc". |
| - reg: Pair of physical base address and region size of the |
| Relay Message Buffer (RMB) registers for this modem. |
| - reg-names: "rmb_base" is required. |
| - qcom,firmware-name: Base filename of the firmware image (e.g. "mdm0"). |
| Maximum size is 4 characters. |
| - qcom,modem-id: Unique ID of this modem. This is not a logical |
| index. |
| - qcom,max-num-images: The maximum number of images that will be loaded to |
| this modem. |
| |
| Optional properties: |
| - qcom,pil-skip-entry-check: |
| Some entry pointers are virtual addresses, |
| which will cause the PIL entry address check |
| to fail. This parameter will disable the |
| check. |
