mfd: intel-lpss-pci: Fix clock speed for 38a8 UART

2022-01-16T08:11:14+00:00

commit 9651cf2cb14726c785240e9dc01b274a68e9959e upstream.

This device is found in the MacBookPro16,2, and as the MacBookPro16,1 is
from the same generation of MacBooks and has a UART with bxt_uart_info,
it was incorrectly assumed that the MacBookPro16,2's UART would have the
same info.

This led to the wrong clock speed being used, and the Bluetooth
controller exposed by the UART receiving and sending random data, which
was incorrectly assumed to be an issue with the Bluetooth stuff, not an
error with the UART side of things.

Changing the info to spt_uart_info changes the clock speed and makes it
send and receive data correctly.

mfd: intel-lpss: Fix too early PM enablement in the ACPI ->probe()

2022-01-16T08:11:14+00:00

commit c9e143084d1a602f829115612e1ec79df3727c8b upstream.

The runtime PM callback may be called as soon as the runtime PM facility
is enabled and activated. It means that ->suspend() may be called before
we finish probing the device in the ACPI case. Hence, NULL pointer
dereference:

  intel-lpss INT34BA:00: IRQ index 0 not found
  BUG: kernel NULL pointer dereference, address: 0000000000000030
  ...
  Workqueue: pm pm_runtime_work
  RIP: 0010:intel_lpss_suspend+0xb/0x40 [intel_lpss]

To fix this, first try to register the device and only after that enable
runtime PM facility.

Pull chrome platform updates from Benson Leung:
 "cros_ec_typec:

   - Clean up use of cros_ec_check_features

  cros_ec_*:

   - Rename and move cros_ec_pd_command to cros_ec_command, and make
     changes to cros_ec_typec and cros_ec_proto to use the new common
     command, reducing duplication.

  sensorhub:

   - simplify getting .driver_data in cros_ec_sensors_core and
     cros_ec_sensorhub

  misc:

   - Maintainership change. Enric Balletbo i Serra has moved on from
     Collabora, so removing him from chrome/platform maintainers. Thanks
     for all of your hard work maintaining this, Enric, and best of luck
     to you in your new role!

   - Add Prashant Malani as driver maintainer for cros_ec_typec.c and
     cros_usbpd_notify. He was already principal contributor of these
     drivers"

mfd: dln2: Add cell for initializing DLN2 ADC

2021-11-05T14:40:27+00:00

This patch extends the DLN2 driver; adding cell for adc_dln2 module.

The original patch[1] fell through the cracks when the driver was added
so ADC has never actually been usable. That patch did not have ACPI
support which was added in v5.9, so the oldest supported version this
current patch can be backported to is 5.10.
