553f0459b8 MAINTAINERS: MTD Git repository is hosted on kernel.org
Because of the slowness of the infradead.org server, Linus requested
that we send him PRs from another domain. We moved our Git repository
to kernel.org and maintain the following branches:
* Fixes based on the last -rc: mtd/fixes
* Next branch based usually on -rc1: mtd/next, nand/next, spi-nor/next.

d81645510c ASoC: Updates for v5.2
This is a pretty huge set of changes, it's been a pretty active release
 all round but the big thing with this release is the Sound Open Firmware
 changes from Intel, providing another DSP framework for use with the
 DSPs in their SoCs.  This one works with the firmware of the same name
 which is free software (unlike the previous DSP firmwares and framework)
 and there has been some interest in adoption by other systems already so
 hopefully we will see adoption by other vendors in the future.
 
 Other highlights incldue:
 
  - Support for MCLK/sample rate ratio setting in the generic cards.
  - Support for pin switches in the generic cards.
  - A big set of improvements to the TLV320AIC32x4 drivers from Annaliese
    McDermond.
  - New drivers for Freescale audio mixers, several Intel machines,
    several Mediatek machines, Meson G12A, Sound Open Firmware and
    Spreadtrum compressed audio and DMA devices.

  through the week whether to send the fixes, and then yesterday Jiri's
  crash fix for a regression introduced in this cycle clearly marked

  Most of the commits are tooling fixes, plus there's three kernel fixes
  via four commits:

    - race fix in the Intel PEBS code

    - fix an AUX bug and roll back a previous attempt

    - fix AMD family 17h generic HW cache-event perf counters

  The largest diffstat contribution comes from the AMD fix - a new event
  table is introduced, which is a fairly low risk change but has a large
  linecount"

7b9487a9a5 clk: analogbits: add Wide-Range PLL library
Add common library code for the Analog Bits Wide-Range PLL (WRPLL) IP
block, as implemented in TSMC CLN28HPC.

There is no bus interface or register target associated with this PLL.
This library is intended to be used by drivers for IP blocks that
expose registers connected to the PLL configuration and status
signals.

554aae3500 lib: Add support for generic packing operations
This provides an unified API for accessing register bit fields
regardless of memory layout. The basic unit of data for these API
functions is the u64. The process of transforming an u64 from native CPU
encoding into the peripheral's encoding is called 'pack', and
transforming it from peripheral to native CPU encoding is 'unpack'.

49b323157b soc: ti: Add MSI domain bus support for Interrupt Aggregator
With the system coprocessor managing the range allocation of the
inputs to Interrupt Aggregator, it is difficult to represent
the device IRQs from DT.

The suggestion is to use MSI in such cases where devices wants
to allocate and group interrupts dynamically.

Create a MSI domain bus layer that allocates and frees MSIs for
a device.

APIs that are implemented:
- ti_sci_inta_msi_create_irq_domain() that creates a MSI domain
- ti_sci_inta_msi_domain_alloc_irqs() that creates MSIs for the
  specified device and resource.
- ti_sci_inta_msi_domain_free_irqs() frees the irqs attached to the device.
- ti_sci_inta_msi_get_virq() for getting the virq attached to a specific event.

9f1463b86c irqchip/ti-sci-inta: Add support for Interrupt Aggregator driver
Texas Instruments' K3 generation SoCs has an IP Interrupt Aggregator
which is an interrupt controller that does the following:
- Converts events to interrupts that can be understood by
  an interrupt router.
- Allows for multiplexing of events to interrupts.

Configuration of the interrupt aggregator registers can only be done by
a system co-processor and the driver needs to send a message to this
co processor over TISCI protocol. Add the required infrastructure to
allow the allocation and routing of these events.

e3037485c6 rtw88: new Realtek 802.11ac driver
This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin

And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.

Supported:

 * Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)

Missing feature:

 * WOW/PNO
 * USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
 * BT coexistence (8822B/8822C are combo ICs)
 * Multiple interfaces (for now single STA is better supported)
 * Dynamic hardware calibrations (to improve/stabilize performance)

Potential problems:

 * static calibration spends too much time, and it is painful for
   driver to leave IDLE state. And slows down associate process.
   But reload function are under development, will be added soon!
 * TRX statictics misleading, as we are not reporting status correctly,
   or say, not reporting for "every" packet.

The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.

Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.

Finally, rtw88 has many authors, listed alphabetically:

====================
pull-request: bpf-next 2019-04-28

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Introduce BPF socket local storage map so that BPF programs can store
   private data they associate with a socket (instead of e.g. separate hash
   table), from Martin.

2) Add support for bpftool to dump BTF types. This is done through a new
   `bpftool btf dump` sub-command, from Andrii.

3) Enable BPF-based flow dissector for skb-less eth_get_headlen() calls which
   was currently not supported since skb was used to lookup netns, from Stanislav.

4) Add an opt-in interface for tracepoints to expose a writable context
   for attached BPF programs, used here for NBD sockets, from Matt.

5) BPF xadd related arm64 JIT fixes and scalability improvements, from Daniel.

6) Change the skb->protocol for bpf_skb_adjust_room() helper in order to
   support tunnels such as sit. Add selftests as well, from Willem.

7) Various smaller misc fixes.

controller is based on DesignWare's IP.

The controller doesn't support accessing the Root Port's config space via
ECAM, so we obtain its base address via an AMZN0001 device.

Furthermore, the DesignWare PCIe controller doesn't filter out config
transactions sent to devices 1 and up on its bus, so they are filtered by
the driver.

All subordinate buses do support ECAM access.

Implementing specific PCI config access functions involves:
 - Adding an init function to obtain the Root Port's base address from
   an AMZN0001 device.
 - Adding a new entry in the MCFG quirk array.

[bhelgaas: Note that there is no Kconfig option for this driver because it
is only intended for use with the generic ACPI host bridge driver.  This
driver is only needed because the DesignWare IP doesn't completely support
ECAM access to the root bus.]

f1d8a071d4 counter: 104-quad-8: Add Generic Counter interface support
This patch adds support for the Generic Counter interface to the
104-QUAD-8 driver. The existing 104-QUAD-8 device interface should not
be affected by this patch; all changes are intended as supplemental
additions as perceived by the user.

Generic Counter Counts are created for the eight quadrature channel
counts, as well as their respective quadrature A and B Signals (which
are associated via respective Synapse structures) and respective index
Signals.

The new Generic Counter interface sysfs attributes are intended to
expose the same functionality and data available via the existing
104-QUAD-8 IIO device interface; the Generic Counter interface serves
to provide the respective functionality and data in a standard way
expected of counter devices.

0040a390d2 counter: Introduce the Generic Counter interface
This patch introduces the Generic Counter interface for supporting
counter devices.

In the context of the Generic Counter interface, a counter is defined as
a device that reports one or more "counts" based on the state changes of
one or more "signals" as evaluated by a defined "count function."

Driver callbacks should be provided to communicate with the device: to
read and write various Signals and Counts, and to set and get the
"action mode" and "count function" for various Synapses and Counts
respectively.

To support a counter device, a driver must first allocate the available
Counter Signals via counter_signal structures. These Signals should
be stored as an array and set to the signals array member of an
allocated counter_device structure before the Counter is registered to
the system.

Counter Counts may be allocated via counter_count structures, and
respective Counter Signal associations (Synapses) made via
counter_synapse structures. Associated counter_synapse structures are
stored as an array and set to the the synapses array member of the
respective counter_count structure. These counter_count structures are
set to the counts array member of an allocated counter_device structure
before the Counter is registered to the system.

A counter device is registered to the system by passing the respective
initialized counter_device structure to the counter_register function;
similarly, the counter_unregister function unregisters the respective
Counter. The devm_counter_register and devm_counter_unregister functions
serve as device memory-managed versions of the counter_register and
counter_unregister functions respectively.

It's time to officially admit I'm not doing anything useful for
mach-davinci anymore.  Since Bartosz is bringing all the code I wrote
10+ years ago into the modern era, he should take over.
