net: ipa: more include file cleanup

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

All of the config data files and all of the register definition files (plus a few others) use GSI_EE_AP, which is defined in "ipa_version.h". Include that header where it's needed. All of the IPA register definition files include "../ipa.h", though none of them need anything defined there. Similarly, all of the GSI register definition files include "../gsi.h", but don't need anything defined there. Remove these unnneded includes. All of the configuration data files include "../gsi.h", though none of them need anything defined there, so remove these includes. Remove other includes of local header files that are not required.

net: ipa: remove unneeded standard includes

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

Some IPA header files include one or more other standard header files despite not directly needing anything defined in the included files. Remove these unnecessary includes. Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni

net: ipa: pass a platform device to ipa_reg_init()

2024-03-04T11:44:40+00:00

Rather than using the platform device pointer field in the IPA pointer, pass a platform device pointer to ipa_reg_init(). Use that pointer throughout that function. Signed-off-by: Alex Elder Signed-off-by: David S. Miller

net: ipa: add IPA v5.5 register definitions

2023-11-24T12:18:55+00:00

GSI register definitions for IPA v5.5 are the same as those used for IPA v5.0. Update ipa_reg_id_valid() to reflect that IPA v5.0+ supports source and destination resource groups 4 through 7. Add the definitions of IPA register offsets and fields for IPA v5.5. Signed-off-by: Alex Elder Signed-off-by: David S. Miller

net: ipa: prepare for IPA v5.5

2023-11-24T12:18:55+00:00

For IPA v5.5+, the QTIME_TIMESTAMP_CFG register no longer defines two fields in the DPL timestamp. Make the code referencing those fields in ipa_qtime_config() conditional based on IPA version. IPA v5.0+ supports the IPA_MEM_AP_V4_FILTER and IPA_MEM_AP_V6_FILTER memory regions. Update ipa_mem_id_valid() to reflect that. IPA v5.5 no longer supports a few register fields, adds some others, and removes support for a few IPA interrupt types. Update "ipa_reg.h" to include information about IPA v5.5.

net: ipa: update IPA version comments in "ipa_reg.h"

2023-11-24T12:18:54+00:00

Some definitions in "ipa_reg.h" are only valid for certain versions of IPA. In such cases a comment indicates a version or range of versions where the definition is (or is not) valid. Almost all such cases look like "IPA vX.Y", but a few don't include the "IPA" tag. Update these so they all consistently include "IPA". And replace a few lines that talk about "the next bit" in the definition of the ipa_irq_id enumerated type with a more concise comment using the "IPA vX.Y" convention.

net: ipa: add IPA v5.0 register definitions

2023-03-23T05:44:00+00:00

Add the definitions of IPA register offsets and fields for IPA v5.0. These are used for the SDX65 SoC. In the Makefile, split IPA_VERSIONS to use IPA_REG_VERSIONS and IPA_DATA_VERSIONS instead, to allow IPA register definitions for a new version to be added separate from the IPA data. Rename GSI_IPA_VERSIONS to be GSI_REG_VERSIONS for consistency. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: fix some register validity checks

2023-03-17T04:33:18+00:00

A recent commit defined HW_PARAM_4 as a GSI register ID but did not add it to gsi_reg_id_valid() to indicate it's valid (for IPA v5.0+). Add version checks for the HW_PARAM_2 and INTER_EE IRQ GSI registers there as well. IPA v5.0 supports up to 8 source and destination resource groups. Update the validity check (and the comments where the register IDs are defined) to reflect that. Similarly update comments and validity checks for the hash/cache-related registers. Note that this patch fixes an omission and constrains things further, but these don't technically represent bugs.

net: ipa: kill FILT_ROUT_CACHE_CFG IPA register

2023-03-17T04:33:18+00:00

A recent commit defined a few IPA registers used for IPA v5.0+. One of those was a mistake. Although the filter and router caches get *flushed* using a single register, they use distinct registers (ENDP_FILTER_CACHE_CFG and ENDP_ROUTER_CACHE_CFG) for configuration. And although there *exists* a FILT_ROUT_CACHE_CFG register, it is not needed in upstream code. So get rid of definitions related to FILT_ROUT_CACHE_CFG, because they are not needed.

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.
