usb: dwc_otg_310: pcd: fix force device mode issue

When tested usb device through force device mode method,
we found that usb device failed to connect to usb host
in the following case.

1. Use micro usb 2.0 OTG interface.
2. Plug in otg cable, and the id pin was pulled down
   to Ground.
3. User space force usb to enter device mode through
   'echo 2 > /sys/bus/platform/drivers/usb20_otg/force_usb_mode'
4. Use usb 2.0 Standard-A to Standard-A cable assembly,
   plug into otg cable receptor on one side, and connect
   to PC on the other side.
5. PC fail to enumerate our device, because of usb driver
   logical issue.

This is because that the dwc_otg_pcd_check_vbus_work()
only enable usb to start connecting if check the bvalid
and iddig is high. But in the above test case, the iddig
is low, so fail to start connection work. In this patch,
we enable usb to connect if iddig is high or usb is in
force device mode.

In addition, fix some coding style to increase the readability.

UPSTREAM: pinctrl: rockchip: Add iomux-route switching support

On the some rockchip SOCS, some things like rk3399 specific uart2 can use
multiple pins. Somewhere between the pin io-cells and the uart it seems
to have some sort of switch to decide to which pin to actually route the
data.

+-------+    +--------+  /- GPIO4_B0 (pinmux 2)

| uart2 | -- | switch | --- GPIO4_C0 (pinmux 2)

+-------+    +--------+  \- GPIO4_C3 (pinmux 2)
(switch selects one of the 3 pins base on the GRF_SOC_CON7[BIT0, BIT1])

The routing switch is determined by one pin of a specific group to be set
to its special pinmux function. If the pinmux setting is wrong for that
pin the ip block won't work correctly anyway.

can enter N/A MODE4 for "port mirroring" feature.

To provide normal operation of the PHY, one needs not only to explicitly
disable the port mirroring feature, but as well stop some IC internal
testing (which disables RGMII communication).

To do that the STRAP_STS1 (0x006E) register must be read and RESERVED bit
11 examined. When it is set, the another RESERVED bit (11) at PHYCR
(0x0010) register must be clear to disable testing mode and enable RGMII
communication.

Thorough explanation of the problem can be found at following e2e thread:
"DP83867IR: Problem with RESERVED bits in PHY Control Register (PHYCR) -
Linux driver"

UPSTREAM: net: phy: dp83867: Add lane swapping support in the DP83867 TI's PHY driver

This patch adds support for enabling or disabling the lane swapping (called
"port mirroring" in PHY's CFG4 register) feature of the DP83867 TI's PHY
device.

One use case is when bootstrap configuration enables this feature (because
of e.g. LED_0 wrong wiring) so then one needs to disable it in software
(at u-boot/Linux).

UPSTREAM: net: phy: dp83867: fix irq generation

For proper IRQ generation by DP83867 phy the INT/PWDN pin has to be
programmed as an interrupt output instead of a Powerdown input in
Configuration Register 3 (CFG3), Address 0x001E, bit 7 INT_OE = 1. The
current driver doesn't do this and as result IRQs will not be generated by
DP83867 phy even if they are properly configured in DT.

Hence, fix IRQ generation by properly configuring CFG3.INT_OE bit and
ensure that Link Status Change (LINK_STATUS_CHNG_INT) and Auto-Negotiation
Complete (AUTONEG_COMP_INT) interrupt are enabled. After this the DP83867
driver will work properly in interrupt enabled mode.

and then we can access the usb core registers safely, it

Also, we avoid to call otg20_hcd_connect_detect() if dwc2

we will do the same work in check_id_work() later. This can

because of hc list is NULL.

port1 work the same as otg-port host mode.

cpufreq: rockchip: limit frequency when reboot

If i2c driver adds a shutdown callback function, the callback will be
executed before cpu's shutdown callback when reboot system, it will
fail to scale voltage like the following.
rk3x-i2c ff650000.i2c: Access denied - device already shutdown
rk3x-i2c ff650000.i2c: Access denied - device already shutdown
rk3x-i2c ff650000.i2c: Access denied - device already shutdown
rk3x-i2c ff650000.i2c: Access denied - device already shutdown
cpu cpu4: _set_opp_voltage: failed to set voltage
(950000 950000 1350000 mV):-5

So add a reboot notifier to limit frequency before i2c's shutdown callback,
and the cpu's shutdown callback will do nothing.

UPSTREAM: dma-buf: Add ioctls to allow userspace to flush

The userspace might need some sort of cache coherency management e.g. when CPU
and GPU domains are being accessed through dma-buf at the same time. To
circumvent this problem there are begin/end coherency markers, that forward
directly to existing dma-buf device drivers vfunc hooks. Userspace can make use
of those markers through the DMA_BUF_IOCTL_SYNC ioctl. The sequence would be
used like following:
     - mmap dma-buf fd
     - for each drawing/upload cycle in CPU 1. SYNC_START ioctl, 2. read/write
       to mmap area 3. SYNC_END ioctl. This can be repeated as often as you
       want (with the new data being consumed by the GPU or say scanout device)
     - munmap once you don't need the buffer any more

BackPort:
  upstream kernel change dma-buf api with the commit(831e9da
  dma-buf: Remove range-based flush), avoid effect too much to
  current kernel, Just compatible dma-buf api to current version.

v2 (Tiago): Fix header file type names (u64 -> __u64)
v3 (Tiago): Add documentation. Use enum dma_buf_sync_flags to the begin/end
dma-buf functions. Check for overflows in start/length.
v4 (Tiago): use 2d regions for sync.
v5 (Tiago): forget about 2d regions (v4); use _IOW in DMA_BUF_IOCTL_SYNC and
remove range information from struct dma_buf_sync.
v6 (Tiago): use __u64 structured padded flags instead enum. Adjust
documentation about the recommendation on using sync ioctls.
v7 (Tiago): Alex' nit on flags definition and being even more wording in the
doc about sync usage.
v9 (Tiago): remove useless is_dma_buf_file check. Fix sync.flags conditionals
and its mask order check. Add <linux/types.h> include in dma-buf.h.
