Subject: [PATCH RESEND v6 0/4] Driver for Apple Z2 touchscreens.
Date: Mon, 17 Feb 2025 12:38:00 +0100 [thread overview]
Message-ID: <20250217-z2-v6-0-c2115d6e5a8f@gmail.com> (raw)
Hi.
This series adds support for Apple touchscreens using the Z2 protocol.
Those are used as the primary touchscreen on mobile Apple devices, and for the
touchbar on laptops using the M-series chips. (T1/T2 laptops have a coprocessor
in charge of speaking Z2 to the touchbar).
Originally sent as a RFC at https://lore.kernel.org/all/20230223-z2-for-ml-v1-0-028f2b85dc15@gmail.com/
The changes since then mostly address the review feedback, but also
add another machine that has this specific controller.

Changes in v6:
- Went back to build_cal_blob returning an allocated buffer, other fixes.
- Link to v5: https://lore.kernel.org/r/20250118-z2-v5-0-6d38b2582169@gmail.com
Changes in v5:
- Added missing \ns, removed 4kb-ish of wasted ram
- Link to v4: https://lore.kernel.org/r/20250115-z2-v4-0-d7361ab16ba0@gmail.com
Changes in v4:
- Dropped another allocation, other fixes.
- Link to v3: https://lore.kernel.org/r/20250112-z2-v3-0-5c0e555d3df1@gmail.com
Changes in v3:
- Tx/Rx buffers used in interrupt handler are now allocated in probe and reused
- Other various style fixes
- Link to v2: https://lore.kernel.org/r/20241128-z2-v2-0-76cc59bbf117@gmail.com
Changes in v2:
- In a separate patch, fixed an issue that prevented the SPI controller
from using GPIO CS, and as such, moved the hardware quirk to there
- Went back to uploading the firmware in probe() instad of open()
- Other changes addressing the review feedback
- Link to v1: https://lore.kernel.org/r/20241126-z2-v1-0-c43c4cc6200d@gmail.com
