2023-07-31ACPI: scan: Create platform device for CS35L56Simon Trimmer1-0/+14
The ACPI device CSC3556 is a Cirrus Logic CS35L56 mono amplifier which is used in multiples, and can be connected either to I2C or SPI. There will be multiple instances under the same Device() node. Add it to ignore_serial_bus_ids and handle it in the serial-multi-instantiate driver. There can be a 5th I2cSerialBusV2, but this is an alias address and doesn't represent a real device. Ignore this by having a dummy 5th entry in the serial-multi-instantiate instance list with the name of a non-existent driver, on the same pattern as done for bsg2150.

This function escapes certain special characters like \n. So if the last character in the string is a '\n' then it gets changed into two characters '\' and '\n'. But maybe we only have space for the '\' so we need to check for that. The "conv_dst_size" variable is always less than or to equal the "size" variable.

System76 EC since system76/ec@9ac513128ad9 detects if the keyboard is white or RGB backlit via `RGBKB-DET#` at run-time instead of being set at compile-time. As part of this, the brightness of white-only backlit keyboards was also changed to behave more like the RGB-backlit keyboards: a value between 0 and 255 instead of a firmware-defined level. The EC ACPI methods in coreboot have been updated for this new functionality only, removing the old behavior. This should preserve behavior as we roll out new firmware with these changes included and users update to it.

2023-07-25platform/x86: msi-laptop: Fix rfkill out-of-sync on MSI Wind U100Maxim Mikityanskiy1-4/+4
Only the HW rfkill state is toggled on laptops with quirks->ec_read_only (so far only MSI Wind U90/U100). There are, however, a few issues with the implementation: 1. The initial HW state is always unblocked, regardless of the actual state on boot, because msi_init_rfkill only sets the SW state, regardless of ec_read_only. 2. The initial SW state corresponds to the actual state on boot, but it can't be changed afterwards, because set_device_state returns -EOPNOTSUPP. It confuses the userspace, making Wi-Fi and/or Bluetooth unusable if it was blocked on boot, and breaking the airplane mode if the rfkill was unblocked on boot. Address the above issues by properly initializing the HW state on ec_read_only laptops and by allowing the userspace to toggle the SW state. Don't set the SW state ourselves and let the userspace fully control it. Toggling the SW state is a no-op, however, it allows the userspace to properly toggle the airplane mode. The actual SW radio disablement is handled by the corresponding rtl818x_pci and btusb drivers that have their own rfkills. Tested on MSI Wind U100 Plus, BIOS ver 1.0G, EC ver 130.

HP Elite Dragonfly G2 (a convertible laptop/tablet) has a reliable VGBS method. If VGBS is not called on boot, the firmware sends an initial 0xcd event shortly after calling the BTNL method, but only if the device is booted in the laptop mode. However, if the device is booted in the tablet mode and VGBS is not called, there is no initial 0xcc event, and the input device for SW_TABLET_MODE is not registered up until the user turns the device into the laptop mode. Call VGBS on boot on this device to get the initial state of SW_TABLET_MODE in a reliable way. Tested with BIOS 1.13.1.

2023-07-25platform/x86: intel: hid: Always call BTNL ACPI methodHans de Goede1-12/+9
On a HP Elite Dragonfly G2 the 0xcc and 0xcd events for SW_TABLET_MODE are only send after the BTNL ACPI method has been called. Likely more devices need this, so make the BTNL ACPI method unconditional instead of only doing it on devices with a 5 button array. Note this also makes the intel_button_array_enable() call in probe() unconditional, that function does its own priv->array check. This makes the intel_button_array_enable() call in probe() consistent with the calls done on suspend/resume which also rely on the priv->array check inside the function.

2023-07-14platform/x86: serial-multi-instantiate: Auto detect IRQ resource for CSC3551David Xu1-4/+17
The current code assumes that the CSC3551(multiple cs35l41) always have its interrupt pin connected to GPIO thus the IRQ can be acquired with acpi_dev_gpio_irq_get. However on some newer laptop models this is no longer the case as they have the CSC3551's interrupt pin connected to APIC. This causes smi_i2c_probe to fail on these machines. To support these machines, a new macro IRQ_RESOURCE_AUTO was introduced for cs35l41 smi_node, and smi_get_irq function was modified so it tries to get GPIO irq resource first and if failed, tries to get APIC irq resource for cs35l41. This patch affects only the cs35l41's probing and brings no negative influence on machines that indeed have the cs35l41's interrupt pin connected to GPIO.

2023-07-12platform/x86: asus-wmi: add safety checks to gpu switchingLuke D. Jones1-0/+48
Add safety checking to dgpu_disable, egpu_enable, gpu_mux_mode. These checks prevent users from doing such things as: - disabling the dGPU while is muxed to drive the internal screen - enabling the eGPU which also disables the dGPU, while muxed to the internal screen - switching the MUX to dGPU while the dGPU is disabled Signed-off-by: Luke D.
