Could you please resend against linux-next (or my 'next' branch)? Patch #3 should go through Sven's tree. Thanks.
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. Signed-off-by: Sasha Finkelstein <fnkl.kernel@gmail.com> --- Changes in v7: - Added a dependency on ARCH_APPLE to prevent potential confusion on x86 - Link to v6: https://lore.kernel.org/r/20250205-z2-v6-0-cc60cbee1d5b@gmail.com 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 --- Sasha Finkelstein (4): dt-bindings: input: touchscreen: Add Z2 controller input: apple_z2: Add a driver for Apple Z2 touchscreens arm64: dts: apple: Add touchbar digitizer nodes MAINTAINERS: Add entries for Apple Z2 touchscreen driver .../input/touchscreen/apple,z2-multitouch.yaml | 70 +++ MAINTAINERS | 2 + arch/arm64/boot/dts/apple/t8103-j293.dts | 27 ++ arch/arm64/boot/dts/apple/t8103.dtsi | 19 + arch/arm64/boot/dts/apple/t8112-j493.dts | 23 + arch/arm64/boot/dts/apple/t8112.dtsi | 14 + drivers/input/touchscreen/Kconfig | 13 + drivers/input/touchscreen/Makefile | 1 + drivers/input/touchscreen/apple_z2.c | 473 +++++++++++++++++++++ 9 files changed, 642 insertions(+) --- base-commit: b62cef9a5c673f1b8083159f5dc03c1c5daced2f change-id: 20241124-z2-c012b528ea0d
