     Shevchenko)

     PNP_UART1_SKIP quirk for Lenovo Blade2 tablets (Hans de Goede)

   - Move acpi_blacklisted() declaration to asm/acpi.h (Kuppuswamy
     Sathyanarayanan)

   - Add Lunar Lake support to the ACPI DPTF driver (Sumeet Pawnikar)

   - Mark the einj_driver driver's remove callback as __exit because it
     cannot get unbound via sysfs (Uwe Kleine-König)

   - Fix a typo in the ACPI documentation regarding the layout of sysfs
     subdirectory representing the ACPI namespace (John Watts)

   - Make the ACPI pfrut utility print the update_cap field during
     capability query (Chen Yu)

   - Add HAS_IOPORT dependencies to PNP (Niklas Schnelle)"

platform/chrome: cros_ec: Handle events during suspend after resume completion

2024-04-30T01:38:04+00:00

Commit 47ea0ddb1f56 ("platform/chrome: cros_ec_lpc: Separate host
command and irq disable") re-ordered the resume sequence. Before that
change, cros_ec resume sequence is:
1) Enable IRQ
2) Send resume event
3) Handle events during suspend

After commit 47ea0ddb1f56 ("platform/chrome: cros_ec_lpc: Separate host
command and irq disable"), cros_ec resume sequence is:
1) Enable IRQ
2) Handle events during suspend
3) Send resume event.

This re-ordering leads to delayed handling of any events queued between
items 2) and 3) with the updated sequence. Also in certain platforms, EC
skips triggering interrupt for certain events eg. mkbp events until the
resume event is received. Such events are stuck in the host event queue
indefinitely. This change puts back the original order to avoid any
delay in handling the pending events.

platform/chrome: cros_ec_lpc: add quirks for the Framework Laptop (AMD)

2024-04-24T08:46:00+00:00

The original Framework Laptop 13 platform (Intel 11th, 12th, and 13th
Generation at this time) uses a Microchip embedded controller in a
standard configuration.

The newer devices in this product line--Framework Laptop 13 and 16 (AMD
Ryzen)--use a NPCX embedded controller. However, they deviate from the
configuration of ChromeOS platforms built with the NPCX EC.

* The MMIO region for EC memory begins at port 0xE00 rather than the
  expected 0x900.

cros_ec_lpc's quirks system is used to address this issue.

platform/chrome: cros_ec_lpc: add a "quirks" system

2024-04-24T08:46:00+00:00

Some devices ship a ChromeOS EC in a non-standard configuration. Quirks
allow cros_ec_lpc to account for these non-standard configurations.

It only supports one quirk right now:

2024-04-24T08:45:59+00:00

lpc_driver_data stores the MMIO port base for EC mapped memory.
cros_ec_lpc_readmem uses this port base instead of hardcoding
EC_LPC_ADDR_MEMMAP.

platform/chrome: add HAS_IOPORT dependencies

2024-04-24T08:45:59+00:00

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. We thus need to add HAS_IOPORT as dependency for those
drivers using them.

primary match.

Also shrink the name for fitting to [2].
