[BUG] intel-quickspi: touchscreen DMA write timeout (Goodix 27C6:012D) on Lenovo YOGA Pro 16 IAH10

[Qiao Ruihao]

Hello,

The touchscreen on my Lenovo YOGA Pro 16 IAH10 does not work under
Linux. The intel-quickspi driver detects the device, but the
feature-report fetch (GET_REPORT) fails with a TxDMA write timeout,
which makes hid-multitouch fail initialization and fall back to a
generic keyboard, so the screen does not respond to any touch input.

The touchscreen works correctly under Windows 11 on the same hardware.

## Hardware

  - Laptop: Lenovo YOGA Pro 16 IAH10 (MT 83L0)
  - CPU: Intel Arrow Lake-H
  - Touchscreen: Goodix 27C6:012D, connected via Intel THC QuickSPI
  - THC controller: 00:10.0 Digitizer Pen [8086:7749] (rev 03),
    subsystem Lenovo [17aa:3815]

## Software

  - Kernel: 7.0.14-070014-generic
    (also reproduced on 6.19.14-061914-generic)
  - Distro: Ubuntu 22.04.5 LTS

## Problem

At boot the device is detected (reset + device descriptor read
succeed), but then hid-multitouch fails to fetch its feature reports
because every GET_REPORT command sent over TxDMA times out.

## Relevant kernel log

  intel_quickspi 0000:00:10.0: Can't find wake GPIO resource
  ACPI: \_SB.PC00.THC0._RST: Excess arguments - Caller passed 1, ACPI requires 0

  hid-multitouch 0001:27C6:012D.0002: failed to fetch feature 3
  hid-multitouch 0001:27C6:012D.0002: input,hidraw1: <UNKNOWN> HID v8.65 Keyboard [quickspi-hid 27C6:012D]

## Analysis

The reset (acpi_tic_reset via _RST) and device-descriptor read
succeed, so the SPI link and interrupt path partially work. The
failure is specific to quickspi_get_report() ->
write_cmd_to_txdma() -> thc_dma_write(): the TxDMA transfer never
completes (write_done is never set, 1s timeout -> -ETIMEDOUT).

I would be happy to provide additional information (full dmesg, ACPI
tables, register dumps) or test patches.

Thanks,
Qiao Ruihao

Could you attach full dmesg too?
