soundwire: pass sdw_bpt_section to cdns BPT helpers

2025-12-08T07:07:27Z

We can get start_register, data_size, and buffer data from the new sdw_bpt_section parameter. Also, handle all register sections in the cdns BRA helpers. No function changes as section number is 1.

soundwire: introduce BPT section

2025-12-08T07:07:27Z

Currently we send a BRA message with a start address with continuous registers in a BPT stream. However, a codec may need to write different register sections shortly. Introduce a register section in struct sdw_btp_msg which contain register start address, length, and buffer. This commit uses only 1 section for each BPT message. And we need to add up all BPT section length and check if it reach maximum BPT bytes. No function changes.

soundwire: intel_ace2x: add fake frame to BRA read command

2025-12-08T07:07:26Z

Intel DMA buffer size need to be a multiple of data block size. Find the minimal fake data size and extra buffer size to meet the requirement.

soundwire: cadence_master: add fake_size parameter to sdw_cdns_prepare_read_dma_buffer

2025-12-08T07:07:26Z

We may need to add few fake frames to fit the aligned read dma buffer size. Add a fake_size parameter to allow the caller to set the fake data size.

soundwire: update Intel BPT message length limitation

2025-06-09T16:12:18Z

The limitation of "must be multiples of 32 bytes" does not fit the requirement of current Intel platforms. Update it to meet the requirement.

module: Convert symbol namespace to string literal

2024-12-02T19:34:44Z

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.
