net: ipa: sort all includes

2024-04-18T11:01:05+00:00

Establish the rule that header files are always included in sorted (POSIX local) order. Standard and private headers are separated by a blank line. Similarly, sort all forward-declarations for structures. Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni

net: ipa: include some standard header files

2024-04-18T11:01:05+00:00

Some IPA header files use types defined in , but do not include that file: - In "ipa_mem.h", the ipa_mem structure has u16 and u32 fields - In "ipa_power.h", ipa_power_retention() takes a bool argument, and ipa_core_clock_rate() returns u32 - In "ipa_version.h", ipa_version_supported() returns bool Include it in these files to satisfy their dependencies. The ipa_qmi structure (defined in "ipa_qmi.h") contains a work structure, so include in there. All of the data and register definition files, as well as "reg.h", use the ARRAY_SIZE() macro. Include everywhere it's used. Similarly, all register definition files (and a few others) use the GENMASK() macro, so include to ensure it's defined where used. BIT() becomes available by including this file also. Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni

When "reg.h" got created, it included calls to WARN() and WARN_ON(). Those macros are defined via . In addition, it uses is_power_of_2(), which is defined in . Include those files so IPA "reg.h" has access to all definitions it requires. Meanwhile, is included but nothing defined therein is required directly in "reg.h", so get rid of that.

net: ipa: generalize register field functions

2023-02-10T08:06:32+00:00

Rename functions related to register fields so they don't appear to be IPA-specific, and move their definitions into "reg.h": ipa_reg_fmask() -> reg_fmask() ipa_reg_bit() -> reg_bit() ipa_reg_field_max() -> reg_field_max() ipa_reg_encode() -> reg_encode() ipa_reg_decode() -> reg_decode() Signed-off-by: Alex Elder Signed-off-by: David S.

net: ipa: generalize register offset functions

2023-02-10T08:06:32+00:00

Rename ipa_reg_offset() to be reg_offset() and move its definition to "reg.h". Rename ipa_reg_n_offset() to be reg_n_offset() also. Signed-off-by: Alex Elder Signed-off-by: David S. Miller

IPA register definitions have evolved with each new version. The changes required to support more than 32 endpoints in IPA v5.0 made it best to define a unified mechanism for defining registers and their fields. GSI register definitions, meanwhile, have remained fairly stable. And even as the total number of IPA endpoints goes beyond 32, the number of GSI channels on a given EE that underly endpoints still remains 32 or less. Despite that, GSI v3.0 (which is used with IPA v5.0) extends the number of channels (and events) it supports to be about 256, and as a result, many GSI register definitions must change significantly. To address this, we'll use the same "ipa_reg" mechanism to define the GSI registers. As a first step in generalizing the "ipa_reg" to also support GSI registers, isolate the definitions of the "ipa_reg" and "ipa_regs" structure types (and some supporting macros) into a new header file, and remove the "ipa_" and "IPA_" from symbol names. Separate the IPA register ID validity checking from the generic check that a register ID is in range. Aside from that, this is intended to have no functional effect on the code.
