Alex Elder says: ==================== net: ipa: a few last bits This series incorporates a few last things that didn't fit neatly with patches I've posted recently. The first patch eliminates all remaining kernel-doc warnings. There's still room for kernel-doc improvement, but at least what's there will no longer produce warnings. The next moves the definition of the value to store in the backward compatibility register (when present) into platform data files. The third removes two endpoint definitions that do not need to be defined. The next two switch the naming convention used for configuration data files to be based on the IPA version rather than the specific platform. I was skeptical about this at first (i.e., I thought a platform might have quirks separate from the IPA version). But I'm now convinced the IPA version is enough to define the details of the hardware block. If any exceptions to this are found, we can treat those differently. Note: these two patches produce warnings from checkpatch.pl about updating MAINTAINERS: these can be ignored. The sixth removes unnecessary checks for alignment of DMA memory allocations, based comments from David Laight. And the last removes a symbol representing the size of a table entry, using sizeof(__le64) in its place. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Entries in an IPA route or filter table are 64-bit little-endian addresses, each of which refers to a routing or filtering rule. The format of these table slots are fixed, but IPA_TABLE_ENTRY_SIZE is used to define their size. This symbol doesn't really add value, and I think it unnecessarily obscures what a table entry *is*. So get rid of IPA_TABLE_ENTRY_SIZE, and just use sizeof(__le64) in its place throughout the code. Update the comments in "ipa_table.c" to provide a little better explanation of these table slots.

A recent patch avoided doing 64-bit modulo operations by checking the alignment of some DMA allocations using only the lower 32 bits of the address. David Laight pointed out (after the fix was committed) that DMA allocations might already satisfy the alignment requirements. And he was right. Remove the alignment checks that occur after DMA allocation requests, and update comments to explain why the constraint is satisfied. The only place IPA_TABLE_ALIGN was used was to check the alignment; it is therefore no longer needed, so get rid of it. Add comments where GSI_RING_ELEMENT_SIZE and the tre_count and event_count channel data fields are defined to make explicit they are required to be powers of 2. Revise a comment in gsi_trans_pool_init_dma(), taking into account that dma_alloc_coherent() guarantees its result is aligned to a page size (or order thereof). Don't bother printing an error if a DMA allocation fails. Suggested-by:

Rename the SC7180 configuration data file so that its name is derived from its IPA version. Update a few other references to the code that talk about the SC7180 rather than just IPA v4.2. Signed-off-by:

Rename the SDM845 configuration data file so that its name is derived from its IPA version. I am not aware of any special IPA behavior or handling that would be based on a specific SoC (as opposed to a specific version of the IPA it contains). Update a few other references to the code that talk about the SDM845 rather than just IPA v3.5.1. Signed-off-by:

We don't typically need much information about modem endpoints. Normally we need to specify information about modem endpoints in configuration data in only two cases: - When a modem TX endpoint supports filtering - When another endpoint's configuration refers to it For the first case, the AP initializes the filter table, and must know how many endpoints (AP and modem) support filtering. An example of the second case is the AP->modem TX endpoint, which defines the modem<-AP RX endpoint as its status endpoint. There is one exception to this, and it's due to a hardware quirk. For IPA v4.2 (only) there is a problem related to allocating GSI channels. And to work around this, the AP allocates *all* GSI channels at startup time--including those used by the modem. Get rid of the configuration information for two endpoints not required for the SDM845. SC7180 runs IPA v4.2, so we can't eliminate any modem endpoint definitions there. Two more minor changes: - Reorder the members defined for the ipa_endpoint_name enumerated type to match the order used in configuration data files when defining endpoints. - Add a new name, IPA_ENDPOINT_MODEM_DL_NLO_TX, which can be used for IPA v4.5+.

The backward compatibility register value is a platform-specific property that is not stored in the platform data. Create a data field where this can be represented, and get rid ipa_reg_bcr_val(). This register is not present starting with IPA v4.5. Signed-off-by:

Three minor changes: - When disabling PLL, there is no need to call core_write_mmd_indirect directly, use the core_write wrapper instead like the rest of the code in the function does. This change helps with consistency and readability. Move the comment to the definition of core_read_mmd_indirect where it belongs. - Disable both core and TRGMII Tx clocks prior to reconfiguring. Previously, only the core clock was disabled, but not TRGMII Tx clock. So disable both, then configure them, then re-enable both, for consistency. - The core clock enable bit (REG_GSWCK_EN) is written redundantly three times. Simplify the code and only write the register only once at the end of clock reconfiguration to enable both core and TRGMII Tx clocks. Tested on Ubiquiti ER-X running the GMAC0 and MT7530 in TRGMII mode. Signed-off-by:

After resilient next-hop groups have been added recently, there are two types of multipath next-hop groups: the legacy "mpath", and the new "resilient". Calling the legacy next-hop group type "mpath" is unfortunate, because that describes the fact that a packet could be forwarded in one of several paths, which is also true for the resilient next-hop groups. Therefore, to make the naming clearer, rename various artifacts to reflect the assumptions made. Therefore as of this patch: - The flag for multipath groups is nh_grp_entry::is_multipath. This includes the legacy and resilient groups, as well as any future group types that behave as multipath groups. Functions that assume this have "mpath" in the name. - The flag for legacy multipath groups is nh_grp_entry::hash_threshold. Functions that assume this have "hthr" in the name. - The flag for resilient groups is nh_grp_entry::resilient. Functions that assume this have "res" in the name. Besides the above, struct nh_grp_entry::mpath was renamed to ::hthr as well. UAPI artifacts were obviously left intact. Suggested-by:
