In ipa_uc_response_hdlr() a comment uses the wrong function name when it describes where a clock reference is taken. Fix this. Also fix the comment in ipa_uc_response_hdlr() to correctly refer to ipa_uc_setup(), which is where the clock reference described here is taken.

/**
|
|
* DOC: IPA Registers
|
|
*
|
|
* IPA registers are located within the "ipa-reg" address space defined by
|
|
* Device Tree. The offset of each register within that space is specified
|
|
* by symbols defined below. The address space is mapped to virtual memory
|
|
* space in ipa_mem_init(). All IPA registers are 32 bits wide.
|
|
*
|
|
* Certain register types are duplicated for a number of instances of
|
|
* something. For example, each IPA endpoint has an set of registers
|
|
* defining its configuration. The offset to an endpoint's set of registers
|
|
* is computed based on an "base" offset, plus an endpoint's ID multiplied
|
|
* and a "stride" value for the register. For such registers, the offset is
|
|
* computed by a function-like macro that takes a parameter used in the
|
|
* computation.
|
|
*
|
|
* Some register offsets depend on execution environment. For these an "ee"
|
|
* parameter is supplied to the offset macro. The "ee" value is a member of
|
|
* the gsi_ee enumerated type.
|
|
*
|
|
* The offset of a register dependent on endpoint ID is computed by a macro
|
|
* that is supplied a parameter "ep", "txep", or "rxep". A register with an
|
|
* "ep" parameter is valid for any endpoint; a register with a "txep" or
|
|
* "rxep" parameter is valid only for TX or RX endpoints, respectively. The
|
|
* "*ep" value is assumed to be less than the maximum valid endpoint ID
|
|
* for the current hardware, and that will not exceed IPA_ENDPOINT_MAX.
|
|
*
|
|
* The offset of registers related to filter and route tables is computed
|
|
* by a macro that is supplied a parameter "er". The "er" represents an
|
|
* endpoint ID for filters, or a route ID for routes. For filters, the
|
|
* endpoint ID must be less than IPA_ENDPOINT_MAX, but is further restricted
|
|
* because not all endpoints support filtering. For routes, the route ID
|
|
* must be less than IPA_ROUTE_MAX.
|
|
*
|
|
* The offset of registers related to resource types is computed by a macro
|
|
* that is supplied a parameter "rt". The "rt" represents a resource type,
|
|
* which is is a member of the ipa_resource_type_src enumerated type for
|
|
* source endpoint resources or the ipa_resource_type_dst enumerated type
|
|
* for destination endpoint resources.
|
|
*
|
|
* Some registers encode multiple fields within them. For these, each field
|
|
* has a symbol below defining a field mask that encodes both the position
|
|
* and width of the field within its register.
|
|
*
|
|
* In some cases, different versions of IPA hardware use different offset or
|
|
* field mask values. In such cases an inline_function(ipa) is used rather
|
|
* than a MACRO to define the offset or field mask to use.
|
|
*
|
|
* Finally, some registers hold bitmasks representing endpoints. In such
|
|
* cases the @available field in the @ipa structure defines the "full" set
|
|
* of valid bits for the register.
