soc: qcom: ipa: GSI headers
The Generic Software Interface is a layer of the IPA driver that abstracts the underlying hardware. The next patch includes the main code for GSI (including some additional documentation). This patch just includes three GSI header files. - "gsi.h" is the top-level GSI header file. This structure is is embedded within the IPA structure. The main abstraction implemented by the GSI code is the channel, and this header exposes several operations that can be performed on a GSI channel. - "gsi_private.h" exposes some definitions that are intended to be private, used only by the main GSI code and the GSI transaction code (defined in an upcoming patch). - Like "ipa_reg.h", "gsi_reg.h" defines the offsets of the 32-bit registers used by the GSI layer, along with masks that define the position and width of fields less than 32 bits located within these registers.

|

* DOC: GSI Registers
|
||||
*
|
||||
* GSI registers are located within the "gsi" address space defined by Device
|
||||
* Tree. The offset of each register within that space is specified by
|
||||
* symbols defined below. The GSI address space is mapped to virtual memory
|
||||
* space in gsi_init(). All GSI registers are 32 bits wide.
|
||||
*
|
||||
* Each register type is duplicated for a number of instances of something.
|
||||
* For example, each GSI channel has its own set of registers defining its
|
||||
* configuration. The offset to a channel's set of registers is computed
|
||||
* based on a "base" offset plus an additional "stride" amount computed
|
||||
* from the channel's ID. For such registers, the offset is computed by a
|
||||
* function-like macro that takes a parameter used in the computation.
|
||||
*
|
||||
* The offset of a register dependent on execution environment is computed
|
||||
* by a macro that is supplied a parameter "ee". The "ee" value is a member
|
||||
* of the gsi_ee_id enumerated type.
|
||||
*
|
||||
* The offset of a channel register is computed by a macro that is supplied a
|
||||
* parameter "ch". The "ch" value is a channel id whose maximum value is 30
|
||||
* (though the actual limit is hardware-dependent).
|
||||
*
|
||||
* The offset of an event register is computed by a macro that is supplied a
|
||||
* parameter "ev". The "ev" value is an event id whose maximum value is 15
|
||||
* (though the actual limit is hardware-dependent).
