We should signal connect (pull up dp) after we have already
at peripheral mode, otherwise, the dp may be toggled due to
we reset controller or do disconnect during the initialization
for peripheral, then, the host may be confused during the
enumeration, eg, it finds the reset can't succeed, but the
device is still there, see below error message.

A new uas compatible controller has shown up in some people's devices from
the manufacturer Initio Corporation, this controller needs the US_FL_NO_ATA_1X
quirk to work properly with uas, so add it to the uas quirks table.

radeon_bo_create() calls radeon_ttm_placement_from_domain()
before ttm_bo_init() is called. radeon_ttm_placement_from_domain()
uses the ttm bo size to determine when to select top down
allocation but since the ttm bo is not initialized yet the
check is always false. It only took effect when buffers
were validated later. It also seemed to regress suspend
and resume on some systems possibly due to it not
taking effect in radeon_bo_create().
radeon_bo_create() and radeon_ttm_placement_from_domain()
need to be reworked substantially for this to be optimally
effective. Re-enable it at that point.

The EHCI IP only needs the UTMI/UPLL (uclk) and the peripheral (iclk)
clocks to work properly. Remove the useless system clock (fclk).
Avoid calling set_rate on the fixed rate UTMI/IPLL clock and remove
useless IS_ENABLED(CONFIG_COMMON_CLK) tests (all at91 platforms have been
moved to the CCF).
This patch also fixes a bug introduced by 3440ef1 (ARM: at91/dt: fix USB
high-speed clock to select UTMI), which was leaving the usb clock
uninitialized and preventing the OHCI driver from setting the usb clock
rate to 48MHz.
This bug was caused by several things:
1/ usb clock drivers set the CLK_SET_RATE_GATE flag, which means the rate
cannot be changed once the clock is prepared
2/ The EHCI driver was retrieving and preparing/enabling the uhpck
clock which was in turn preparing its parent clock (the usb clock),
thus preventing any rate change because of 1/

Since commit 0f04cf8df0b20a97369cb634663fef0578cbf273 ("drm/exynos:
fix wrong pipe calculation for crtc"), fimd_clear_channel() can be
called when is_drm_iommu_supported() returns true. In this case,
the kernel is going to be panicked because crtc is not set yet.

On sun4i-a10, when GPIOs are configured as external interrupt the value for
them in the data register does not seem to get updated, so set their mux to
input (and restore afterwards) when reading the pin.
Missed edges seem to be buffered, so this does not introduce a race
condition.
I've also tested this on sun5i-a13 and sun7i-a20 and those do not seem to
be affected, the input value representation in the data register does seem
to correctly get updated to the actual pin value while in irq mode there.

The gpiochip_lock_as_irq call can fail and return an error,
while the irq_startup is not expected to fail (returns an
unsigned int which is not checked by irq core code).
irq_request/release_resources functions have been created
to address this problem.
Move gpiochip_lock/unlock_as_irq calls into
irq_request/release_resources functions to prevent using a
gpio as an irq if the gpiochip_lock_as_irq call failed.

The commit breaks the legacy platforms, ie. these not using device-tree,
and setting up the interrupt resources with a flag to activate edge
detection. The issue was found on the zylonite platform.
The reason is that zylonite uses platform resources to pass the interrupt number
and the irq flags (here IORESOURCE_IRQ_HIGHEDGE). It expects the driver to
request the irq with these flags, which in turn setups the irq as high edge
triggered.
After the patch, this was supposed to be taken care of with :
irq_resflags = irqd_get_trigger_type(irq_get_irq_data(ndev->irq));
But irq_resflags is 0 for legacy platforms, while for example in
arch/arm/mach-pxa/zylonite.c, in struct resource smc91x_resources[] the
irq flag is specified. This breaks zylonite because the interrupt is not
setup as triggered, and hardware doesn't provide interrupts.

Going over the virtio mmio code, I noticed that it doesn't correctly
access modern device config values using "natural" accessors: it uses
readb to get/set them byte by byte, while the virtio 1.0 spec explicitly states:
4.2.2.2 Driver Requirements: MMIO Device Register Layout
...
The driver MUST only use 32 bit wide and aligned reads and writes to
access the control registers described in table 4.1.
For the device-specific configuration space, the driver MUST use
8 bit wide accesses for 8 bit wide fields, 16 bit wide and aligned
accesses for 16 bit wide fields and 32 bit wide and aligned accesses for
32 and 64 bit wide fields.
Borrow code from virtio_pci_modern to do this correctly.

Complete bong hit (and not the last...), the hardware will reassert the
interrupt to PMC if it's necessary.
Also potentially harmful in the face of interrupts such as the non-stall
interrupt, which remain active in NV_PFIFO_INTR even when we don't care
about servicing it.
It appears (hopefully, fdo#87244), that under certain loads, the methods
may pass quickly enough to hit the "100 spins and kill PFIFO" thing that
we had going on. Not ideal ;)

Setting of those features is conditional on "!CHIP_IS_E1x(bp)", but
the bp struct is not initialized yet at this point and consequently
any chip passes the check.
The check must use the "chip_is_e1x" local variable instead to work

--"Static context mode should be used for the first channel called
after reset to ensure that the all context RAM for that channel is
initialized during the context SAVE phase when the channel is
done or yields. Subsequent calls to the same channel or
different channels may use any of the dynamic context modes.
This will ensure that all context locations for the bootload
channel are initialized, and prevent undefined values in context

plane->state->fb and plane->fb should always reference the same FB so
that atomic and legacy codepaths have the same view of display state.
However, there are some places in kernel code that directly set
plane->fb and neglect to update plane->state->fb. If we never do a
successful update through the atomic pipeline, the RmFB cleanup code
will look at the plane->state->fb pointer, which has never actually
been set to a legitimate value, and try to clean it up, leading to
BUG's.
Add a quick helper function to synchronize plane->state->fb with
plane->fb and call it everywhere the driver tries to manually set
plane->fb outside of the atomic pipeline. In this function, use
drm_atomic_set_fb_for_plane instead of writing plane->state->fb
directly to keep the reference count right.

The linux kernel has supported the TiVo Slide remote control for some time, but
does not recognize the USB ID of the newer Slide Pro. This patch adds the
missing data structures so the newer remote will be recognized by the driver,
thereby allowing the TiVo, LiveTV, and Thumbs Up/Down buttons to be
mapped with a hwdb file.

This patch adds response to a_alt_hnp_support set feature request from legacy
A device, that is, B-device can provide a message to the user indicating that
the user needs to connect the B-device to an alternate port on the A-device.
A device sets this feature indicates to the B-device that it is connected
to an A-device port that is not capable of HNP, but that the A-device does have
an alternate port that is capable of HNP.
[Peter]
Without this patch, the OTG B device can't be enumerated on
non-HNP port at A device, see below log:
[ 2.287464] usb 1-1: Dual-Role OTG device on non-HNP port
[ 2.293105] usb 1-1: can't set HNP mode: -32

Kishon writes:
contains fixes all over drivers/phy and includes the following
*) Using phy_get_drvdata instead of dev_get_drvdata in armada375-usb2.c
*) Fixes w.r.t checking return values in regmap APIs, protecting regmap ops
with spin lock and directly using regmap_update_bits instead of having a
separate function to do the same in the various PHYs used in exynos.
*) check return value in platform_get_resource of hix5hd2-sata PHY
*) Removed NULL terminating entry from phys array and fix off-by-one
valid value checking for args->args[0] in of_xlate of exynos USB PHY.
*) Fixup rockchip_usb_phy_power_on failure path
*) Fix devm_phy_match to find the correct match in phy core and also fix to
return the correct value from PHY APIs if PM runtime is not enabled.
*) Removed redundant code in twl4030 and xgene
*) Fixed sizeof during memory allocation in miphy PHYs
*) simplify ti_pipe3_dpll_wait_lock implementation, fix missing clk_prepare
when using old dt name and nit pick in MOUDLE_ALIAS in TI PHYs.
