[ Upstream commit 6c5c659dfe3f02e08054a6c20019e3886618b512 ]
On a config (such as arch/sh/) which does not set HAS_DMA when MMU
is not set, several ATMEL ASoC drivers select symbols that cause
kconfig warnings. There is one "depends on HAS_DMA" which is no longer
needed. Dropping it eliminates the kconfig warnings and still builds
with no problems reported.
Fix the following kconfig warnings:

[ Upstream commit 2e6d793e1bf07fe5e20cfbbdcec9e1af7e5097eb ]
This uses the sg_pcopy_from_buffer to copy data, instead of doing it
ourselves.
In addition to reducing code size, this fixes the following oops
resulting from failing to kmap the page:

[ Upstream commit 6ad61a7847da09b6261824accb539d05bcdfef65 ]
When the VP8 decoders can't find a reference frame,
the driver falls back to the current output frame.
This will probably produce some undesirable results,
leading to frame corruption, but shouldn't cause
noisy warnings.

This patch is part of a quite extensive series touching multiple
drivers and devicetree descriptions and will do more harm than good if
backported without the rest of the series. The options here are:
a) backport the entire series (this will most likely not match the
stable criteria)
b) drop the patch from the stable queue
Regards,
Lucas

ERR009165 fixed on i.mx6ul/6ull/6sll. All other i.mx6/7 and
i.mx8m/8mm still need this errata. Please refer to nxp official
errata document from https://www.nxp.com/ .
For removing workaround on those chips. Add new i.mx6ul type.

[ Upstream commit 7ab1f6539762946de06ca14d7401ae123821bc40 ]
Regulator node names don't reflect class of the device. Fix that by
prefixing names with "regulator-".

[ Upstream commit 818c4593434e81c9971b8fc278215121622c755e ]
The wrong property "atmel,shdwc-debouncer" was used to specify the
debounce delay for the shutdown controler. Replace it with the
documented and implemented property "debounce-delay-us", as mentioned
in v4 driver submission. See:

[ Upstream commit 0ada1697ed4256b38225319c9896661142a3572d ]
When the stream fails to start, the first two buffers in the queue have
been moved to the active_vb2_buf array and are returned to vb2 by
imx7_csi_dma_unsetup_vb2_buf(). The function is called with the buffer
state set to VB2_BUF_STATE_ERROR unconditionally, which is correct when
stopping the stream, but not when the start operation fails. In that
case, the state should be set to VB2_BUF_STATE_QUEUED. Fix it.

[ Upstream commit cd7cd5b716d594e27a933c12f026d4f2426d7bf4 ]
PPD has only one ACHC device, which effectively is a Kinetis
microcontroller. It has one SPI interface used for normal
communication. Additionally it's possible to flash the device
firmware using NXP's EzPort protocol by correctly driving a
second chip select pin and the device reset pin.

From: Nathan Chancellor <nathan@kernel.org>
[ Upstream commit 4367355dd90942a71641c98c40c74589c9bddf90 ]
When compiling with clang in certain configurations, an objtool warning
appears:
drivers/net/ethernet/stmicro/stmmac/dwmac-ipq806x.o: warning: objtool:
ipq806x_gmac_probe() falls through to next function phy_modes()
This happens because the unreachable annotation in the third switch
statement is not eliminated. The compiler should know that the first
default case would prevent the second and third from being reached as
the comment notes but sanitizer options can make it harder for the
compiler to reason this out.
Help the compiler out by eliminating the unreachable() annotation and
unifying the default case error handling so that there is no objtool
warning, the meaning of the code stays the same, and there is less
duplication.

From: Quanyang Wang <quanyang.wang@windriver.com>
[ Upstream commit a19effb6dbe5bd1be77a6d68eba04dba8993ffeb ]
The Runtime PM subsystem will force the device "fd4a0000.zynqmp-display"
to enter suspend state while booting if the following conditions are met:
- the usage counter is zero (pm_runtime_get_sync hasn't been called yet)
- no 'active' children (no zynqmp-dp-snd-xx node under dpsub node)
- no other device in the same power domain (dpdma node has no
"power-domains = <&zynqmp_firmware PD_DP>" property)
So there is a scenario as below:
1) DP device enters suspend state <- call zynqmp_gpd_power_off
2) zynqmp_disp_crtc_setup_clock <- configurate register VPLL_FRAC_CFG
3) pm_runtime_get_sync <- call zynqmp_gpd_power_on and clear previous
VPLL_FRAC_CFG configuration
4) clk_prepare_enable(disp->pclk) <- enable failed since VPLL_FRAC_CFG
configuration is corrupted
From above, we can see that pm_runtime_get_sync may clear register
VPLL_FRAC_CFG configuration and result the failure of clk enabling.
Putting pm_runtime_get_sync at the very beginning of the function
zynqmp_disp_crtc_atomic_enable can resolve this issue.

[ Upstream commit a338619bd76011035d462f0f9e8b2f24d7fe5a1e ]
When insmod zynqmp-dpsub.ko after rmmod it, system will hang with the
error log as below:
root@xilinx-zynqmp:~# insmod zynqmp-dpsub.ko
[ 88.391289] [drm] Initialized zynqmp-dpsub 1.0.0 20130509 for fd4a0000.display on minor 0
[ 88.529906] Console: switching to colour frame buffer device 128x48

[ 94.023404] Console: switching to colour dummy device 80x25
root@xilinx-zynqmp:~# insmod zynqmp-dpsub.ko
<hang here>
This is because that in zynqmp_dp_probe it tries to access some DP
registers while the DP controller is still in the reset state. When
running "rmmod zynqmp_dpsub", zynqmp_dp_reset(dp, true) in
zynqmp_dp_phy_exit is called to force the DP controller into the reset
state. Then insmod will call zynqmp_dp_probe to program the DP registers,
but at this moment the DP controller hasn't been brought out of the reset
state yet since the function zynqmp_dp_reset(dp, false) is called later and
this will result the system hang.
Releasing the reset to DP controller before any read/write operation to it
will fix this issue. And for symmetry, move zynqmp_dp_reset() call from
zynqmp_dp_phy_exit() to zynqmp_dp_remove().

[ Upstream commit bd306fdb4e60bcb1d7ea5431a74092803d3784a6 ]
The GW71xx has a USB Type-C connector with USB 2.0 signaling. GPIO1_12
is the power-enable to the TPS25821 Source controller and power switch
responsible for monitoring the CC pins and enabling VBUS. Therefore
GPIO1_12 must always be enabled and the vbus output enable from the
IMX8MM can be ignored.
To fix USB OTG VBUS enable a pull-up on GPIO1_12 to always power the
TPS25821 and change the regulator output to GPIO1_10 which is
unconnected.

[ Upstream commit 83e5dcbece4ea67ec3ad94b897e2844184802fd7 ]
When skipping the tests due to a lack of system support for MTE we
currently print a message saying FAIL which makes it look like the test
failed even though the test did actually report KSFT_SKIP, creating some
confusion. Change the error message to say SKIP instead so things are
clearer.

The PAC tests check to see if the system supports the relevant PAC features
but instead of skipping the tests if they can't be executed they fail the
tests which makes things look like they're not working when they are.

[ Upstream commit c626f3864bbbb28bbe06476b0b497c1330aa4463 ]
In certain randconfigs, clang warns:
drivers/gpu/drm/exynos/exynos_drm_dma.c:121:19: warning: variable
'mapping' is uninitialized when used here [-Wuninitialized]
priv->mapping = mapping;
^~~~~~~
drivers/gpu/drm/exynos/exynos_drm_dma.c:111:16: note: initialize the
variable 'mapping' to silence this warning
void *mapping;
^
= NULL
1 warning generated.
This occurs when CONFIG_EXYNOS_IOMMU is enabled and both
CONFIG_ARM_DMA_USE_IOMMU and CONFIG_IOMMU_DMA are disabled, which makes
the code look like
void *mapping;
if (0)
mapping = arm_iommu_create_mapping()
else if (0)
mapping = iommu_get_domain_for_dev()
...
priv->mapping = mapping;
Add an else branch that initializes mapping to the -ENODEV error pointer
so that there is no more warning and the driver does not change during
runtime.

[ Upstream commit c0b4e411a9b09748466ee06d2ae6772effa64dfb ]
SD standard speed timing was met only at 19MHz and not 25 MHz, that's
why changing driver to 19MHz. The reason for this is when a level shifter
is used on the board, timing was met for standard speed only at 19MHz.
Since this level shifter is commonly required for high speed modes,
the driver is modified to use standard speed of 19Mhz.

[ Upstream commit 6a48d0ae01a6ab05ae5e78328546a2f5f6d3054a ]
If IRQ occurs between calling devm_request_threaded_irq() and
initializing dwc3_imx->dwc3, then null pointer dereference occurs
since dwc3_imx->dwc3 is used in dwc3_imx8mp_interrupt().
The patch puts registration of the interrupt handler after
initializing of neccesery data.

[ Upstream commit b8731209958a1dffccc2888121f4c0280c990550 ]
xhci-mtk depends on xhci's internal virt_dev when it retrieves its
internal data from usb_host_endpoint both in add_endpoint and
drop_endpoint callbacks. But when setup packet was retired by
transaction errors in xhci_setup_device() path, a virt_dev for the slot
is newly created with real_port 0. This leads to xhci-mtks's NULL pointer
dereference from drop_endpoint callback as xhci-mtk assumes that virt_dev's
real_port is always started from one. The similar problems were addressed
by [1] but that can't cover the failure cases from setup_device.
This patch drops the usages of xhci's virt_dev in xhci-mtk's drop_endpoint
callback by adopting rhashtable for searching mtk's schedule entity
from a given usb_host_endpoint pointer instead of searching a linked list.
So mtk's drop_endpoint callback doesn't have to rely on virt_dev at all.

[ Upstream commit 53ca9b9777b95cdd689181d7c547e38dc79adad0 ]
