NFC: 3.20 first pull request
This is the first NFC pull request for 3.20.
With this one we have:
- Secure element support for the ST Micro st21nfca driver. This depends
on a few HCI internal changes in order for example to support more
than one secure element per controller.
- ACPI support for NXP's pn544 HCI driver. This controller is found on
many x86 SoCs and is typically enumerated on the ACPI bus there.
- A few st21nfca and st21nfcb fixes.

+Description: Display fw status registers content
+
+ The ME FW writes its status information into fw status
+ registers for BIOS and OS to monitor fw health.
+
+ The register contains running state, power management
+ state, error codes, and others. The way the registers
+ are decoded depends on PCH or SoC generation.
+ Also number of registers varies between 1 and 6
+ depending on generation.

-
- To enable a trigger, write its name preceded by '+' to

- by '-' instead.
-
- For example, to enable the keyboard as trigger run:
- echo +keyboard > /sys/class/leds/dell::kbd_backlight/start_triggers
- To disable it:
- echo -keyboard > /sys/class/leds/dell::kbd_backlight/start_triggers

-Description:
- This file allows to specify the interval after which the
- keyboard illumination is disabled because of inactivity.
- The timeouts are expressed in seconds, minutes, hours and
- days, for which the symbols are 's', 'm', 'h' and 'd'

-
- To configure the timeout, write to this file a value along
- with any the above units. If no unit is specified, the value
- is assumed to be expressed in seconds.
-
- For example, to set the timeout to 10 minutes run:
- echo 10m > /sys/class/leds/dell::kbd_backlight/stop_timeout
-
- Note that when this file is read, the returned value might be
- expressed in a different unit than the one used when the timeout
- was set.
-
- Also note that only some timeouts are supported and that
- some systems might fall back to a specific timeout in case
- an invalid timeout is written to this file.

+* QEMU Firmware Configuration bindings for ARM
+
+QEMU's arm-softmmu and aarch64-softmmu emulation / virtualization targets
+provide the following Firmware Configuration interface on the "virt" machine
+type:
+
+- A write-only, 16-bit wide selector (or control) register,
+- a read-write, 64-bit wide data register.
+
+QEMU exposes the control and data register to ARM guests as memory mapped
+registers; their location is communicated to the guest's UEFI firmware in the
+DTB that QEMU places at the bottom of the guest's DRAM.
+
+The guest writes a selector value (a key) to the selector register, and then
+can read the corresponding data (produced by QEMU) via the data register. If
+the selected entry is writable, the guest can rewrite it through the data
+register.
+
+The selector register takes keys in big endian byte order.
+
+The data register allows accesses with 8, 16, 32 and 64-bit width (only at
+offset 0 of the register). Accesses larger than a byte are interpreted as
+arrays, bundled together only for better performance. The bytes constituting
+such a word, in increasing address order, correspond to the bytes that would
+have been transferred by byte-wide accesses in chronological order.
+
+The interface allows guest firmware to download various parameters and blobs
+that affect how the firmware works and what tables it installs for the guest
+OS. For example, boot order of devices, ACPI tables, SMBIOS tables, kernel and
+initrd images for direct kernel booting, virtual machine UUID, SMP information,
+virtual NUMA topology, and so on.
+
+The authoritative registry of the valid selector values and their meanings is
+the QEMU source code; the structure of the data blobs corresponding to the
+individual key values is also defined in the QEMU source code.
+
+The presence of the registers can be verified by selecting the "signature" blob
+with key 0x0000, and reading four bytes from the data register. The returned
+signature is "QEMU".
+
+The outermost protocol (involving the write / read sequences of the control and
+data registers) is expected to be versioned, and/or described by feature bits.
+The interface revision / feature bitmap can be retrieved with key 0x0001. The
+blob to be read from the data register has size 4, and it is to be interpreted
+as a uint32_t value in little endian byte order. The current value
+(corresponding to the above outer protocol) is zero.
+
+The guest kernel is not expected to use these registers (although it is
+certainly allowed to); the device tree bindings are documented here because
+this is where device tree bindings reside in general.
+
+Required properties:
+
+- compatible: "qemu,fw-cfg-mmio".
+
+- reg: the MMIO region used by the device.
+ * Bytes 0x0 to 0x7 cover the data register.
+ * Bytes 0x8 to 0x9 cover the selector register.
+ * Further registers may be appended to the region in case of future interface
+ revisions / feature bits.
+
+Example:
+
+/ {
+ #size-cells = <0x2>;
+ #address-cells = <0x2>;
+
+ fw-cfg@9020000 {
+ compatible = "qemu,fw-cfg-mmio";
+ reg = <0x0 0x9020000 0x0 0xa>;
+ };
+};

+-----------------------
+
+An alternative to using the original match portion of a key as the handle for
+flow identification is a unique flow identifier, or "UFID". UFIDs are optional
+for both the kernel and user space program.
+
+User space programs that support UFID are expected to provide it during flow
+setup in addition to the flow, then refer to the flow using the UFID for all

- * KFD Interrupts.
- *
- * AMD GPUs deliver interrupts by pushing an interrupt description onto the
- * interrupt ring and then sending an interrupt. KGD receives the interrupt
- * in ISR and sends us a pointer to each new entry on the interrupt ring.
- *
- * We generally can't process interrupt-signaled events from ISR, so we call
- * out to each interrupt client module (currently only the scheduler) to ask if
- * each interrupt is interesting. If they return true, then it requires further
- * processing so we copy it to an internal interrupt ring and call each
- * interrupt client again from a work-queue.
- *
- * There's no acknowledgment for the interrupts we use. The hardware simply
- * queues a new interrupt each time without waiting.
- *
- * The fixed-size internal queue means that it's possible for us to lose
- * interrupts because we have no back-pressure to the hardware.
