There's no need to check min(budget, NUM_RX_DESC). At first budget
(NAPI_POLL_WEIGHT = 64) is less then NUM_RX_DESC (256).
And more important: Even in case of budget > NUM_RX_DESC we could
safely continue processing descriptors as long as they are owned by
the CPU. In addition replace rx_left with a normal counter variable,
this allows to simplify the code. Last but not least there's no need
any longer to pass the budget as an u32.

The current assumption is that the felix DSA driver has flooding knobs
per traffic class, while ocelot switchdev has a single flooding knob.
This was correct for felix VSC9959 and ocelot VSC7514, but with the
introduction of seville VSC9953, we see a switch driven by felix.c which
has a single flooding knob.
So it is clear that we must do what should have been done from the
beginning, which is not to overwrite the configuration done by ocelot.c
in felix, but instead to teach the common ocelot library about the
differences in our switches, and set up the flooding PGIDs centrally.
The effect that the bogus iteration through FELIX_NUM_TC has upon
seville is quite dramatic. ANA_FLOODING is located at 0x00b548, and
ANA_FLOODING_IPMC is located at 0x00b54c. So the bogus iteration will
actually overwrite ANA_FLOODING_IPMC when attempting to write
ANA_FLOODING[1]. There is no ANA_FLOODING[1] in sevile, just ANA_FLOODING.
And when ANA_FLOODING_IPMC is overwritten with a bogus value, the effect
is that ANA_FLOODING_IPMC gets the value of 0x0003CF7D:
MC6_DATA = 61,
MC6_CTRL = 61,
MC4_DATA = 60,
MC4_CTRL = 0.
Because MC4_CTRL is zero, this means that IPv4 multicast control packets
are not flooded, but dropped. An invalid configuration, and this is how
the issue was actually spotted.

CNTKCTL_EL1.EVNTI
ARM virtual counter supports event stream, it can only trigger an event
when the trigger bit (the value of CNTKCTL_EL1.EVNTI) of CNTVCT_EL0 changes,
so the actual period of event stream is 2^(cntkctl_evnti + 1). For example,
when the trigger bit is 0, then virtual counter trigger an event for every
two cycles.
While we're at it, rework the way we compute the trigger bit position
by making it more obvious that when bits [n:n-1] are both set (with n
being the most significant bit), we pick bit (n + 1).

commit ("b0fc70ce1f02 arm64: berlin: Select DW_APB_TIMER_OF") added the
support for the dw_apb_timer into the arm64 defconfig. However, for some
platforms like the Intel Stratix10 and Agilex, the clock manager doesn't
get loaded until after the timer driver get loaded. Thus, the driver hits
the panic "No clock nor clock-frequency property for" because it cannot
properly get the clock.
This patch adds the error handling needed for the timer driver so that
the kernel can continue booting instead of just hitting the panic.

This patch add support to set the internal pulldown via dt property
and allow simplify the board design for the trace from emmc-phy to
the eMMC chipset.
Default to not set the pull-down.
This patch was inspired from the 4.4 tree of the
Rockchip SDK, where it is enabled unconditional.
The patch had been tested with our rk3399 customized board.

pm_runtime_enable() will decrease power disable depth. Thus a pairing
increment is needed on the error handling path to keep it balanced.

Compile-testing the DRM_MEDIATEK_HDMI driver shows two missing
dependencies, one results in a link failure:
arm-linux-gnueabi-ld: drivers/phy/mediatek/phy-mtk-hdmi.o: in function `mtk_hdmi_phy_probe':
phy-mtk-hdmi.c:(.text+0xd8): undefined reference to `__clk_get_name'
arm-linux-gnueabi-ld: phy-mtk-hdmi.c:(.text+0x12c): undefined reference to `devm_clk_register'
arm-linux-gnueabi-ld: phy-mtk-hdmi.c:(.text+0x250): undefined reference to `of_clk_add_provider'
arm-linux-gnueabi-ld: phy-mtk-hdmi.c:(.text+0x298): undefined reference to `of_clk_src_simple_get'
The other one is a harmless warning:
WARNING: unmet direct dependencies detected for PHY_MTK_HDMI
Depends on [n]: ARCH_MEDIATEK [=n] && OF [=y]
Selected by [y]:
- DRM_MEDIATEK_HDMI [=y] && HAS_IOMEM [=y] && DRM_MEDIATEK [=y]
Fix these by adding dependencies on CONFIG_OF and CONFIG_COMMON_CLK.
With that done, there is also no reason against adding
CONFIG_COMPILE_TEST.

Without CONFIG_PM, there is another warning about an unused function:
drivers/soundwire/intel.c:530:12: error: 'intel_link_power_down' defined but not used [-Werror=unused-function]
After a previous fix, the driver already uses both an #ifdef and
a __maybe_unused annotation but still gets it wrong. Remove the
ifdef and instead use __maybe_unused consistently to avoid the
problem for good.

This change could fix 2 issues on this machine:
- the bass speaker's output volume can't be adjusted, that is because
the bass speaker is routed to the DAC (Nid 0x6) which has no volume
control.
- after plugging a headset with vol+, vol- and pause buttons on it,
press those buttons, nothing happens, this means those buttons
don't work at all. This machine has alc287 codec, need to add the
codec id to the disable/enable_headset_jack_key(), then the headset
button could work.
The quirk of ALC285_FIXUP_THINKPAD_HEADSET_JACK could fix both of these
2 issues.

implement the NCI 2.x initial sequence to support NCI 2.x NFCC.
Since NCI 2.0, CORE_RESET and CORE_INIT sequence have been changed.
If NFCEE supports NCI 2.x, then NCI 2.x initial sequence will work.
In NCI 1.0, Initial sequence and payloads are as below:
(DH) (NFCC)
| -- CORE_RESET_CMD --> |
| <-- CORE_RESET_RSP -- |
| -- CORE_INIT_CMD --> |
| <-- CORE_INIT_RSP -- |
CORE_RESET_RSP payloads are Status, NCI version, Configuration Status.
CORE_INIT_CMD payloads are empty.
CORE_INIT_RSP payloads are Status, NFCC Features,
Number of Supported RF Interfaces, Supported RF Interface,
Max Logical Connections, Max Routing table Size,
Max Control Packet Payload Size, Max Size for Large Parameters,
Manufacturer ID, Manufacturer Specific Information.
In NCI 2.0, Initial Sequence and Parameters are as below:
(DH) (NFCC)
| -- CORE_RESET_CMD --> |
| <-- CORE_RESET_RSP -- |
| <-- CORE_RESET_NTF -- |
| -- CORE_INIT_CMD --> |
| <-- CORE_INIT_RSP -- |
CORE_RESET_RSP payloads are Status.
CORE_RESET_NTF payloads are Reset Trigger,
Configuration Status, NCI Version, Manufacturer ID,
Manufacturer Specific Information Length,
Manufacturer Specific Information.
CORE_INIT_CMD payloads are Feature1, Feature2.
CORE_INIT_RSP payloads are Status, NFCC Features,
Max Logical Connections, Max Routing Table Size,
Max Control Packet Payload Size,
Max Data Packet Payload Size of the Static HCI Connection,
Number of Credits of the Static HCI Connection,
Max NFC-V RF Frame Size, Number of Supported RF Interfaces,

Connect hosts H1 and H2 using two intermediate encapsulation routers
(LER1 and LER2). These routers encapsulate traffic from the hosts,
including the original Ethernet header, into MPLS.
Use ping to test reachability between H1 and H2.
