Embodiment
By describe in detail technical scheme technology contents, structural attitude, realized object and effect, coordinate accompanying drawing to be explained in detail below in conjunction with specific embodiment.In the following description, numerous details is set forth for explanatory purposes providing the thorough understanding to one or more aspect.But it is evident that do not have these details also can put into practice this type of aspect.The list of some terms occurred in literary composition is provided at this:
DeviceTree: be a kind of data structure describing hardware;
DTS:devicetreesource, .dts file is a kind of DeviceTree description of text formatting, .dts file can quote (include) other .dtsi files, and in this article, amendment .dts file also can refer to the .dtsi file that amendment .dts quotes; DTC:devicetreecompiler, is compiled as the instrument of .dtb by .dts;
Particular content of the present invention is realized by illustrating in conjunction with the linux equipment that bootloader guides for the present invention in embodiment, but should understand, the present invention or its improvement also can be applicable to window or mac system, or in conjunction with other starting factor instrument or code, solve the problem that the present invention runs into, realize object of the present invention.In the present invention, said equipment is computer equipment, includes but not limited to: personal computer, server, multi-purpose computer, special purpose computer, the network equipment, embedded device, programmable device, intelligent mobile terminal, intelligent home device, wearable intelligent equipment, vehicle intelligent equipment etc.; Described storage medium, includes but not limited to: RAM, ROM, magnetic disc, tape, CD, flash memory, USB flash disk, portable hard drive, storage card, SD card, EMMC, NANDFlash, memory stick, webserver storage, network cloud storage etc.; See Fig. 2, a kind of embodiment comprises step:
See step S210, configuration .dts file, namely dts file syntax rule is pressed by the initializes configuration information of all dissimilar PMIC of required support write DTS file, also namely according to PMIC and the dts file syntax rule of required support, the initialization information of newly-increased corresponding PMIC in .dts file.Required support PMIC namely preset supported PMIC.The initializes configuration information of PMIC comprises mode of operation and equipment state, voltage, the model etc. of PMIC, and when PMIC initialization, these initializes configuration information are as the parameter of initialization directive.In certain embodiments, the status information in the initializes configuration information of PMIC has three kinds of values, namely enables (okey), forbidding (i.e. disable), empty (not number completion value).Status information in the initialization information of PMIC all in .dts file all can be set to forbidding during configuration .dts file, also it all can be set to enable.By DTC .dts file is compiled as .dtb file again, by the assigned address of .dtb burning file to the storage medium in equipment, i.e. the burning position of the .dtb file of acquiescence or setting.Configuration file is equal to .dtb file or .dts file in the present embodiment.Configuration file also can be the file of other types in other embodiments.
Should be appreciated that .dts file is for recording the initialization information of various PMIC in the present embodiment, namely PMIC initialization information also can be recorded in alternative document with character code or binary form in further embodiments, and the PMIC initialization information read when system starts in this file, for the PMIC initialization in equipment.
See step S220, after equipment energising, take out .dtb files loading in internal memory, and the information of resolving in .dtb file is dts file..dtb file can also can Leader in bootloader.Should be appreciated that, it is not necessary for resolving to dts file, it resolves to dts file is information in order to obtain in file, in the performance history of any this real realization, numerous decision specific to realizing must be carried out, to realize the specific purpose of developer, such as relevant to system and that business is relevant constraint is compatible, and these constraints can be different with realization.
Call I2C see step S230, bootloader to drive.It should be noted that, conventional I2C Interface Controller PMIC, it should be understood that at present, other interfaces also can connect PMIC and for control PMIC, in the specific implementation, according to the difference of control interface, call different interface drivers, namely differ establish a capital be call I2C drive.Bootloader obtains all relevant information of PMIC in .dts.Bootloader obtains and presets the initializes configuration information of supported PMIC in some cases, and in dts file, this category information exists with the form of node (Node) one by one.
Generate the list of the PMIC supported according to all relevant information of obtained PMIC see step S240, bootloader.
See step S250, and attempt using the first corresponding initialization directive collection to carry out hardware initialization according to PMIC list.Such as, a certain PMIC is one of described multiple default supported PMIC, according to the initializes configuration information of a certain PMIC, in conjunction with the PMIC in the first initialization directive collection initialization apparatus of corresponding a certain PMIC.
See step S251, S252, the initialization PMIC that the initializes configuration information of above-mentioned a certain PMIC cannot be correct in conjunction with the first initialization directive collection of its correspondence if use, then attempt the initializes configuration information of another PMIC.Another PMIC above-mentioned is also one of default supported PMIC, and the initializes configuration information of another PMIC above-mentioned is also recorded in configuration file.Until attempt the first initialization directive collection (see step S252, S291) of the PMIC of all pre-supports, or until the integrated merit of the first initialization directive of a certain PMIC has carried out initialization to PMIC.First initialization directive collection is made up of many instructions of initialization PMIC and (also comprises initiation parameter in instruction, the initialization directive of different PMIC is generally different), preferred its can be minimum setup code module, also can be instruction set corresponding to minimum setup code module.First setup code can be that the I2C of each PMIC device described in DTS sends broadcast packet from address in another embodiment, detects whether there is reply handshake, if there is handshake, and initialization success.
See step S260, if the integrated merit of the initialization directive of a certain PMIC has carried out initialization to hardware, then revise the dts file in internal memory, mark wherein can the initializes configuration information of PMIC in successful initialization equipment, namely can be the status information in initialization information corresponding for this PMIC in dts file be revised as to enable (okey), the initialization information of other PMIC be revised as forbidding (disable).In certain embodiments, bootloader by amended dts file transfers to kernel.In certain embodiments, the dts file in internal memory is packaged into dtb data block by bootloader again, and covers the dtb data block on original storage medium.Needing to understand, can be marked by the status information in amendment PMIC initializes configuration information at dts file, also can mark by adding other fields.
Call the second initialization directive collection see step S270, bootloader, initial configuration is carried out to it.After second initialization directive collection initialization, the PMIC in equipment presses set model work, and in certain embodiments, the second initialization directive collection i.e. this PMIC drives.Second initialization directive collection can perform when linux kernel starts, namely jump to linux kernel from bootloader to start, linux kernel loads amended dtb file when starting, if the configuration information of the PMIC in dtb file only enables a PMIC initialization information, other are all forbiddings, namely the status information of the configuration information of a PMIC is only had for enabling, the configuration information of PMIC that then linux calls according to it calls the second initialization directive collection of corresponding PMIC, completes the initialization to PMIC.It should be noted that PMIC generally by Interface Controller such as I2C, before the driving of shelf PMIC, also carrying out initialization to interfaces such as I2C, is also understandable.
