clk: sunxi-ng: v3s: Fix incorrect number of hw_clks.
The hws field of sun8i_v3s_hw_clks has only 74
members. However, the number specified by CLK_NUMBER
is 77 (= CLK_I2S0 + 1). This leads to runtime segmentation
fault that is not always reproducible.

This patch fixes the problem by specifying correct clock number.

arm64: dts: allwinner: a64: olinuxino: Fix SDIO supply regulator
A64-OLinuXino uses DCDC1 (VCC-IO) for MMC1 supply. In commit 916b68cfe4
("arm64: dts: a64-olinuxino: Enable RTL8723BS WiFi") ALDO2 is set, which is
VCC-PL. Since DCDC1 is always present, the boards are working without a
problem.

This patch sets the correct regulator.

arm64: dts: allwinner: a64: olinuxino: Fix eMMC supply regulator
A64-OLinuXino-eMMC uses 1.8V for eMMC supply. This is done via a triple
jumper, which sets VCC-PL to either 1.8V or 3.3V. This setting is different
for boards with and without eMMC.

This is not a big issue for DDR52 mode, however the eMMC will not work in
HS200/HS400, since these modes explicitly requires 1.8V.

43cb86799f drm: meson: venc: cvbs: fix CVBS mode matching
With commit 222ec1618c ("drm: Add aspect ratio parsing in DRM
layer") the drm core started honoring the picture_aspect_ratio field
when comparing two drm_display_modes. Prior to that it was ignored.
When the CVBS encoder driver was initially submitted there was no aspect
ratio check.

Switch from drm_mode_equal() to drm_mode_match() without
DRM_MODE_MATCH_ASPECT_RATIO to fix "kmscube" and X.org output using the
CVBS connector. When (for example) kmscube sets the output mode when
using the CVBS connector it passes HDMI_PICTURE_ASPECT_NONE, making the
drm_mode_equal() fail as it include the aspect ratio.

Prior to this patch kmscube reported:
  failed to set mode: Invalid argument

The CVBS mode checking in the sun4i (drivers/gpu/drm/sun4i/sun4i_tv.c
sun4i_tv_mode_to_drm_mode) and ZTE (drivers/gpu/drm/zte/zx_tvenc.c
tvenc_mode_{pal,ntsc}) drivers don't set the "picture_aspect_ratio" at
all. The Meson VPU driver does not rely on the aspect ratio for the CVBS
output so we can safely decouple it from the hdmi_picture_aspect
setting.

27dbc542f6 PM / devfreq: Use PM QoS for sysfs min/max_freq
Switch the handling of min_freq and max_freq from sysfs to use the
dev_pm_qos_request interface.

Since PM QoS handles frequencies as kHz this change reduces the
precision of min_freq and max_freq. This shouldn't introduce problems
because frequencies which are not an integer number of kHz are likely
not an integer number of Hz either.

Try to ensure compatibility by rounding min values down and rounding
max values up.

2ef139393f clk: imx8m: Suppress bind attrs
The clock drivers on imx8m series are registered as platform devices and
this opens the possibility of reloading the driver at runtime.

This doesn't actually work: clocks are never removed and attempting to

useful

e7096c131e net: WireGuard secure network tunnel
WireGuard is a layer 3 secure networking tunnel made specifically for
the kernel, that aims to be much simpler and easier to audit than IPsec.
Extensive documentation and description of the protocol and
considerations, along with formal proofs of the cryptography, are
available at:

  * https://www.wireguard.com/
  * https://www.wireguard.com/papers/wireguard.pdf

This commit implements WireGuard as a simple network device driver,
accessible in the usual RTNL way used by virtual network drivers. It
makes use of the udp_tunnel APIs, GRO, GSO, NAPI, and the usual set of
networking subsystem APIs. It has a somewhat novel multicore queueing
system designed for maximum throughput and minimal latency of encryption
operations, but it is implemented modestly using workqueues and NAPI.
Configuration is done via generic Netlink, and following a review from
the Netlink maintainer a year ago, several high profile userspace tools
have already implemented the API.

This commit also comes with several different tests, both in-kernel
tests and out-of-kernel tests based on network namespaces, taking profit
of the fact that sockets used by WireGuard intentionally stay in the
namespace the WireGuard interface was originally created, exactly like
the semantics of userspace tun devices. See wireguard.com/netns/ for
pictures and examples.

The source code is fairly short, but rather than combining everything
into a single file, WireGuard is developed as cleanly separable files,
making auditing and comprehension easier. Things are laid out as
follows:

  * noise.[ch], cookie.[ch], messages.h: These implement the bulk of the
    cryptographic aspects of the protocol, and are mostly data-only in
    nature, taking in buffers of bytes and spitting out buffers of
    bytes. They also handle reference counting for their various shared
    pieces of data, like keys and key lists.

  * ratelimiter.[ch]: Used as an integral part of cookie.[ch] for
    ratelimiting certain types of cryptographic operations in accordance
    with particular WireGuard semantics.

  * allowedips.[ch], peerlookup.[ch]: The main lookup structures of
    WireGuard, the former being trie-like with particular semantics, an
    integral part of the design of the protocol, and the latter just
    being nice helper functions around the various hashtables we use.

  * device.[ch]: Implementation of functions for the netdevice and for
    rtnl, responsible for maintaining the life of a given interface and
    wiring it up to the rest of WireGuard.

  * peer.[ch]: Each interface has a list of peers, with helper functions
    available here for creation, destruction, and reference counting.

  * socket.[ch]: Implementation of functions related to udp_socket and
    the general set of kernel socket APIs, for sending and receiving
    ciphertext UDP packets, and taking care of WireGuard-specific sticky
    socket routing semantics for the automatic roaming.

  * netlink.[ch]: Userspace API entry point for configuring WireGuard
    peers and devices. The API has been implemented by several userspace
    tools and network management utility, and the WireGuard project
    distributes the basic wg(8) tool.

  * queueing.[ch]: Shared function on the rx and tx path for handling
    the various queues used in the multicore algorithms.

  * send.c: Handles encrypting outgoing packets in parallel on
    multiple cores, before sending them in order on a single core, via
    workqueues and ring buffers. Also handles sending handshake and cookie
    messages as part of the protocol, in parallel.

  * receive.c: Handles decrypting incoming packets in parallel on
    multiple cores, before passing them off in order to be ingested via
    the rest of the networking subsystem with GRO via the typical NAPI
    poll function. Also handles receiving handshake and cookie messages
    as part of the protocol, in parallel.

  * timers.[ch]: Uses the timer wheel to implement protocol particular
    event timeouts, and gives a set of very simple event-driven entry
    point functions for callers.

  * main.c, version.h: Initialization and deinitialization of the module.

  * selftest/*.h: Runtime unit tests for some of the most security
    sensitive functions.

  * tools/testing/selftests/wireguard/netns.sh: Aforementioned testing
    script using network namespaces.

This commit aims to be as self-contained as possible, implementing
WireGuard as a standalone module not needing much special handling or
coordination from the network subsystem. I expect for future
optimizations to the network stack to positively improve WireGuard, and
vice-versa, but for the time being, this exists as intentionally
standalone.

We introduce a menu option for CONFIG_WIREGUARD, as well as providing a
verbose debug log and self-tests via CONFIG_WIREGUARD_DEBUG.

The original logic is ok for primary display, but will not find out

For example, plane->index is 6 for external display, but there are only
2 layer nr in external display, and this condition will never happen:
if (plane->index < (count + mtk_ddp_comp_layer_nr(comp)))

Fix this by using the offset of the plane to mtk_crtc->planes as index,

e18f64712e clk: imx: Mark dram pll on 8mm and 8mn with CLK_GET_RATE_NOCACHE
DRAM frequency switches are executed in firmware and can change the
configuration of the DRAM PLL outside linux. Mark these CLKs with
CLK_GET_RATE_NOCACHE so we always read back the PLL config registers and
recalculate rates.

In current DRAM frequency tables on 8mm/8mn only the maximum frequency
uses the PLL so it's always configured in the same way. However reading
back the PLL configuration is the correct behavior and allows additional
setpoints in the future.

d9ea9ca2b4 clk: imx8m: Set CLK_GET_RATE_NOCACHE on dram clocks
These clocks are only modified as part of DRAM frequency switches during
which DRAM itself is briefly inaccessible. The switch is performed with
a SMC call to by TF-A which runs from a SRAM area; upon returning to
linux several clocks bits are modified and we need to update them.

For rate bits an easy solution is to just mark with
CLK_GET_RATE_NOCACHE so that new rates are always read back from
registers.

b731fadff4 ARM: dts: e60k02: fix power button
The power button was only producing irqs, but no key events,
Forced power down with long key press works, so probably
only a short spike arrives at the SoC.
Further investigation shows that LDORTC2 is off after boot
of the vendor kernel. LDORTC2 is shared with a GPIO at the pmic
which probably transfers the button press to the SoC.
That regulator off at boot, so "regulator-boot-on" is definitively
wrong. So remove that.

0840a47ee8 ARM: dts: ls1021a-tsn: Use interrupts for the SGMII PHYs
On the LS1021A-TSN board, the 2 Atheros AR8031 PHYs for eth0 and eth1
have interrupt lines connected to the shared IRQ2_B LS1021A pin.

Switching to interrupts offloads the PHY library from the task of
polling the MDIO status and AN registers (1, 4, 5) every second.

Unfortunately, the BCM5464R quad PHY connected to the switch does not
appear to have an interrupt line routed to the SoC.
