Since commit c895f6f703ad ("bpf: correct broken uapi for
BPF_PROG_TYPE_PERF_EVENT program type"), all architectures
(except um) are required to have bpf_perf_event.h in uapi/asm.
Add it to mandatory-y so "make headers_install" can check it.

This patch adds support to run dual pipes simultaneously.
A private ioctl to configure the pipe mode (video or still)
is also implemented.
IPU3 hardware supports a maximum of 2 streams per pipe.
With the support of dual pipes, more than 2 stream outputs
can be achieved.
This helps to support advanced camera features like
Continuous View Finder (CVF) and Snapshot During Video(SDV).
Extend ipu3 IMGU driver to support dual pipes
1. Extend current IMGU device to contain 2 groups
of video nodes and 2 subdevs
2. Extend current css to support 2 pipeline and make
CSS APIs to support 2 pipe
3. Add a v4l2 ctrl to allow user to specify the mode
of the pipe
4. Check media pipeline link status to get enabled
pipes

The dma_direct_supported() function intends to check the DMA mask against
specific values. However, the phys_to_dma() function includes the SME
encryption mask, which defeats the intended purpose of the check. This
results in drivers that support less than 48-bit DMA (SME encryption mask
is bit 47) from being able to set the DMA mask successfully when SME is
active, which results in the driver failing to initialize.
Change the function used to check the mask from phys_to_dma() to
__phys_to_dma() so that the SME encryption mask is not part of the check.

The signal delivery path of posix-timers can try to rearm the timer even if
the interval is zero. That's handled for the common case (hrtimer) but not
for alarm timers. In that case the forwarding function raises a division by
zero exception.
The handling for hrtimer based posix timers is wrong because it marks the
timer as active despite the fact that it is stopped.
Move the check from common_hrtimer_rearm() to posixtimer_rearm() to cure
both issues.

Commit f6aa5beb45be ("serial: 8250: Fix clearing FIFOs in RS485 mode
again") makes a change to FIFO clearing code which its commit message
suggests was intended to be specific to use with RS485 mode, however:
1) The change made does not just affect __do_stop_tx_rs485(), it also
affects other uses of serial8250_clear_fifos() including paths for
starting up, shutting down or auto-configuring a port regardless of
whether it's an RS485 port or not.
2) It makes the assumption that resetting the FIFOs is a no-op when
FIFOs are disabled, and as such it checks for this case & explicitly
avoids setting the FIFO reset bits when the FIFO enable bit is
clear. A reading of the PC16550D manual would suggest that this is
OK since the FIFO should automatically be reset if it is later
enabled, but we support many 16550-compatible devices and have never
required this auto-reset behaviour for at least the whole git era.
Starting to rely on it now seems risky, offers no benefit, and
indeed breaks at least the Ingenic JZ4780's UARTs which reads
garbage when the RX FIFO is enabled if we don't explicitly reset it.
3) By only resetting the FIFOs if they're enabled, the behaviour of
serial8250_do_startup() during boot now depends on what the value of
FCR is before the 8250 driver is probed. This in itself seems
questionable and leaves us with FCR=0 & no FIFO reset if the UART
was used by 8250_early, otherwise it depends upon what the
bootloader left behind.
4) Although the naming of serial8250_clear_fifos() may be unclear, it
is clear that callers of it expect that it will disable FIFOs. Both
serial8250_do_startup() & serial8250_do_shutdown() contain comments
to that effect, and other callers explicitly re-enable the FIFOs
after calling serial8250_clear_fifos(). The premise of that patch
that disabling the FIFOs is incorrect therefore seems wrong.
For these reasons, this reverts commit f6aa5beb45be ("serial: 8250: Fix
clearing FIFOs in RS485 mode again").

Some eMMCs from Micron have been reported to need ~800 ms timeout, while
enabling the CACHE ctrl after running sudden power failure tests. The
needed timeout is greater than what the card specifies as its generic CMD6
timeout, through the EXT_CSD register, hence the problem.
Normally we would introduce a card quirk to extend the timeout for these
specific Micron cards. However, due to the rather complicated debug process
needed to find out the error, let's simply use a minimum timeout of 1600ms,
the double of what has been reported, for all cards when enabling CACHE
ctrl.

even BKOPS and CACHE ctrl became prevented. Let's restore those parts and
allow BKOPS and CACHE ctrl even if HPI isn't supported.

While booting with rootfs on MMC, the following warning is encountered
on OMAP4430:
omap-dma-engine 4a056000.dma-controller: DMA-API: mapping sg segment longer than device claims to support [len=69632] [max=65536]
This is because the DMA engine has a default maximum segment size of 64K
but HSMMC sets:
mmc->max_blk_size = 512; /* Block Length at max can be 1024 */
mmc->max_blk_count = 0xFFFF; /* No. of Blocks is 16 bits */
mmc->max_req_size = mmc->max_blk_size * mmc->max_blk_count;
mmc->max_seg_size = mmc->max_req_size;
which ends up telling the block layer that we support a maximum segment
size of 65535*512, which exceeds the advertised DMA engine capabilities.
Fix this by clamping the maximum segment size to the lower of the
maximum request size and of the DMA engine device used for either DMA
channel.

Recent changes in the mvneta driver reworked allocation
and handling of the ingress buffers to use entire pages.
Apart from that in SW BM scenario the HW must be informed
via PRXDQS about the biggest possible incoming buffer
that can be propagated by RX descriptors.
The BufferSize field was filled according to the MTU-dependent
pkt_size value. Later change to PAGE_SIZE broke RX operation
when usin 64K pages, as the field is simply too small.
This patch conditionally limits the value passed to the BufferSize
of the PRXDQS register, depending on the PAGE_SIZE used.
On the occasion remove now unused frag_size field of the mvneta_port
structure.

Create a net bridge, add eth and vnet to the bridge. The vnet is used
by a virtual machine. When ping the virtual machine from the outside
host and the virtual machine send multicast at the same time, the ping
package will lost.
The multicast package send to the eth, eth will send it to the bridge too,
and the bridge learn the mac of eth. When outside host ping the virtual
mechine, it will match the promisc entry of the eth which is not expected,
and the bridge send it to eth not to vnet, cause ping lost.
So this patch change promisc tcam entry position to the END of 512 tcam
entries, which indicate lower priority. And separate one promisc entry to
two: mc & uc, to avoid package match the wrong tcam entry.

So need doubled ndev->watchdog_timeo if device watchdog occurred
until watchdog_timeo up to 40s and then try resetting to recover

According to the hip06 datasheet:
1.Six registers use wrong address:
RCB_COM_SF_CFG_INTMASK_RING
RCB_COM_SF_CFG_RING_STS
RCB_COM_SF_CFG_RING
RCB_COM_SF_CFG_INTMASK_BD
RCB_COM_SF_CFG_BD_RINT_STS
DSAF_INODE_VC1_IN_PKT_NUM_0_REG
2.The offset of DSAF_INODE_VC1_IN_PKT_NUM_0_REG should be
0x103C + 0x80 * all_chn_num
3.The offset to show the value of DSAF_INODE_IN_DATA_STP_DISC_0_REG
is wrong, so the value of DSAF_INODE_SW_VLAN_TAG_DISC_0_REG will be
overwrite
These registers are only used in "ethtool -d", so that did not cause ndev
to misfunction.

There are two test cases:
1. Remove the 4 modules:hns_enet_drv/hns_dsaf/hnae/hns_mdio,
and install them again, must use "ifconfig down/ifconfig up"
command pair to bring port to work.
This patch calls phy_stop function when init phy to fix this bug.
2. Remove the 2 modules:hns_enet_drv/hns_dsaf, and install them again,
all ports can not use anymore, because of the phy devices register
failed(phy devices already exists).
Phy devices are registered when hns_dsaf installed, this patch
removes them when hns_dsaf removed.
The two cases are sometimes related, fixing the second case also requires
fixing the first case, so fix them together.

According to the hip06 Datasheet:
1. The offset of INGRESS_SW_VLAN_TAG_DISC should be 0x1A00+4*all_chn_num
2. The offset of INGRESS_IN_DATA_STP_DISC should be 0x1A50+4*all_chn_num

Tested with 4.19.9.
v2: Changed from CXT_FIXUP_MUTE_LED_GPIO to CXT_FIXUP_HP_DOCK because
that's what the existing fixups for EliteBooks use.

As a result of investigation for Fireface 800, 'struct snd_ff_spec.regs'
is just for higher address to receive tx asynchronous packets of MIDI
messages, thus it can be simplified.
This commit simplifies it.

This commit adds a functionality to multiplex PCM frames into isochronous
packets and demultiplex PCM frames from isochronous packets for ALSA PCM
applications.
Fireface 800 voluntarily maintains resources for tx isochronous
communication. It performs reservation of isochronous channel and
allocation/update of bandwidth in some cases below:
- at a first request to allocation after bus resets
- at requests to allocation when further bandwidth is required
When request is grant and the unit is prepared, read data from
0x0000801c0008 represents isochronous channel for tx stream, then
the unit can handle requests to start communication. If driver
send the request without checking the register, the unit takes
panic to continue bus resets. The unit starts transmission of
tx packets after receiving several rx packets from driver.
I note that the unit can process tx/rx packets and generate/record
sound regardless of HOST LED.

The way to maintain isochronous resources on bus is different between
Fireface 400/800.
This commit is a preparation. This commit moves a function to allocate resource to
model-dependent implementation.

Fireface 400/800 use three modes against the number of data channels in
data block for both tx/rx packets.
This commit adds refactoring for it. Some enumerators are added to
represent each of mode and a function is added to calculate the mode
from sampling frequency code (sfc).

Both of Fireface 400/800 have the same register to switch frame fetching
mode regardless of difference of available number of PCM frames in
rx isochronous packet.
This commit moves a helper function from model-dependent implementation.
