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.

2023-07-26platform: Explicitly include correct DT includesRob Herring3-2/+1
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

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.

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.

2023-07-14platform/x86/intel/tpmi: Add debugfs interfaceSrinivas Pandruvada1-7/+212
Add debugfs interface for debugging TPMI configuration and register contents. This shows PFS (PM Feature structure) for each TPMI device. For each feature, show full register contents and allow to modify register at an offset. This debugfs interface is not present on locked down kernel with no DEVMEM access and without CAP_SYS_RAWIO permission.

2023-07-14platform/x86/intel/tpmi: Read feature control statusSrinivas Pandruvada1-0/+180
Some of the PM features can be locked or disabled. In that case, write interface can be locked. This status is read via a mailbox. There is one TPMI ID which provides base address for interface and data register for mail box operation. The mailbox operations is defined in the TPMI specification. Refer to https://github.com/intel/tpmi_power_management/ for TPMI specifications. An API is exposed to feature drivers to read feature control status.

2023-07-14platform/x86: simatic-ipc: use extra module loading for watchdogHenning Schild1-23/+19
We recently introduced a way to name additional modules to load for each device. Use that instead of wdtmode to load the watchdog module. This patch does not change behaviour, it is just style.

2023-07-14platform/x86: simatic-ipc: add auto-loading of hwmon modulesHenning Schild1-13/+53
In order to know which hwmon modules to load one would have to usually first probe from user-land i.e. with sensors-detect and create a config for each machine. But here we know exactly what machines we are dealing with, so we can request those howmon modules without user-mode detection and config files.

Siemens Simatic Industrial PCs can monitor the voltage of the CMOS battery with two bits that indicate low or empty state. This can be GPIO or PortIO based. Here we model that as a hwmon voltage. The core driver does the PortIO and provides boilerplate for the GPIO versions. Which are split out to model runtime dependencies while allowing fine-grained kernel configuration.

Expose various CPU and dGPU tunables that are available on many ASUS ROG laptops. The tunables shown in sysfs will vary depending on the CPU and dGPU vendor. All of these variables are write only and there is no easy way to find what the defaults are. In general they seem to default to the max value the vendor sets for the CPU and dGPU package - this is not the same as the min/max writable value. Values written to these variables that are beyond the capabilities of the CPU are ignored by the laptop. Signed-off-by: Luke D.
