[PATCH AUTOSEL 6.6 011/294] arm64: Add support for HIP09 Spectre-BHB mitigation

[Sasha Levin]

From: Jinqian Yang <yangjinqian1@huawei.com>

[ Upstream commit e18c09b204e81702ea63b9f1a81ab003b72e3174 ]

The HIP09 processor is vulnerable to the Spectre-BHB (Branch History
Buffer) attack, which can be exploited to leak information through
branch prediction side channels. This commit adds the MIDR of HIP09
to the list for software mitigation.

[PATCH AUTOSEL 6.6 025/294] spi-rockchip: Fix register out of bounds access

[Sasha Levin]

From: Luis de Arquer <luis.dearquer@inertim.com>

[ Upstream commit 7a874e8b54ea21094f7fd2d428b164394c6cb316 ]

Do not write native chip select stuff for GPIO chip selects.
GPIOs can be numbered much higher than native CS.
Also, it makes no sense.

[PATCH AUTOSEL 6.6 038/294] wifi: mt76: only mark tx-status-failed frames as ACKed on mt76x0/2

[Sasha Levin]

From: Felix Fietkau <nbd@nbd.name>

[ Upstream commit 0c5a89ceddc1728a40cb3313948401dd70e3c649 ]

The interrupt status polling is unreliable, which can cause status events
to get lost. On all newer chips, txs-timeout is an indication that the
packet was either never sent, or never acked.
Fixes issues with inactivity polling.

[PATCH AUTOSEL 6.6 039/294] wifi: mt76: mt7996: revise TXS size

[Sasha Levin]

From: Benjamin Lin <benjamin-jw.lin@mediatek.com>

[ Upstream commit 593c829b4326f7b3b15a69e97c9044ecbad3c319 ]

Size of MPDU/PPDU TXS is 12 DWs.
In mt7996/mt7992, last 4 DWs are reserved, so TXS size was mistakenly
considered to be 8 DWs. However, in mt7990, 9th DW of TXS starts to be used.

[PATCH AUTOSEL 6.6 077/294] ASoC: sun4i-codec: support hp-det-gpios property

[Sasha Levin]

From: Ryan Walklin <ryan@testtoast.com>

[ Upstream commit a149377c033afe6557c50892ebbfc0e8b7e2e253 ]

Add support for GPIO headphone detection with the hp-det-gpios
property. In order for this to properly disable the path upon
removal of headphones, the output must be labelled Headphone which
is a common sink in the driver.

Describe a headphone jack and detection GPIO in the driver, check for
a corresponding device tree node, and enable jack detection in a new
machine init function if described.

[PATCH AUTOSEL 6.6 085/294] arm64/mm: Check PUD_TYPE_TABLE in pud_bad()

[Sasha Levin]

From: Ryan Roberts <ryan.roberts@arm.com>

[ Upstream commit bfb1d2b9021c21891427acc86eb848ccedeb274e ]

pud_bad() is currently defined in terms of pud_table(). Although for some
configs, pud_table() is hard-coded to true i.e. when using 64K base pages
or when page table levels are less than 3.

pud_bad() is intended to check that the pud is configured correctly. Hence
let's open-code the same check that the full version of pud_table() uses
into pud_bad(). Then it always performs the check regardless of the config.

[PATCH AUTOSEL 6.6 086/294] mmc: dw_mmc: add exynos7870 DW MMC support

[Sasha Levin]

From: Kaustabh Chakraborty <kauschluss@disroot.org>

[ Upstream commit 7cbe799ac10fd8be85af5e0615c4337f81e575f3 ]

Add support for Exynos7870 DW MMC controllers, for both SMU and non-SMU
variants. These controllers require a quirk to access 64-bit FIFO in 32-bit
accesses (DW_MMC_QUIRK_FIFO64_32).

[PATCH AUTOSEL 6.6 101/294] watchdog: aspeed: Update bootstatus handling

[Sasha Levin]

From: Chin-Ting Kuo <chin-ting_kuo@aspeedtech.com>

[ Upstream commit 5c03f9f4d36292150c14ebd90788c4d3273ed9dc ]

The boot status in the watchdog device struct is updated during
controller probe stage. Application layer can get the boot status
through the command, cat /sys/class/watchdog/watchdogX/bootstatus.
The bootstatus can be,
WDIOF_CARDRESET => System is reset due to WDT timeout occurs.
Others          => Other reset events, e.g., power on reset.

On ASPEED platforms, boot status is recorded in the SCU registers.
- AST2400: Only a bit is used to represent system reset triggered by
           any WDT controller.
- AST2500/AST2600: System reset triggered by different WDT controllers
                   can be distinguished by different SCU bits.

Besides, on AST2400 and AST2500, since alternating boot event is
also triggered by using WDT timeout mechanism, it is classified
as WDIOF_CARDRESET.

[PATCH AUTOSEL 6.6 112/294] media: c8sectpfe: Call of_node_put(i2c_bus) only once in c8sectpfe_probe()

[Sasha Levin]

From: Markus Elfring <elfring@users.sourceforge.net>

[ Upstream commit b773530a34df0687020520015057075f8b7b4ac4 ]

An of_node_put(i2c_bus) call was immediately used after a pointer check
for an of_find_i2c_adapter_by_node() call in this function implementation.
Thus call such a function only once instead directly before the check.

This issue was transformed by using the Coccinelle software.

[PATCH AUTOSEL 6.6 127/294] drm/rockchip: vop2: Add uv swap for cluster window

[Sasha Levin]

From: Andy Yan <andy.yan@rock-chips.com>

[ Upstream commit e7aae9f6d762139f8d2b86db03793ae0ab3dd802 ]

The Cluster windows of upcoming VOP on rk3576 also support
linear YUV support, we need to set uv swap bit for it.

As the VOP2_WIN_UV_SWA register defined on rk3568/rk3588 is
0xffffffff, so this register will not be touched on these
two platforms.

[PATCH AUTOSEL 6.6 130/294] clk: imx8mp: inform CCF of maximum frequency of clocks

[Sasha Levin]

From: Ahmad Fatoum <a.fatoum@pengutronix.de>

[ Upstream commit 06a61b5cb6a8638fa8823cd09b17233b29696fa2 ]

The IMX8MPCEC datasheet lists maximum frequencies allowed for different
modules. Some of these limits are universal, but some depend on
whether the SoC is operating in nominal or in overdrive mode.

The imx8mp.dtsi currently assumes overdrive mode and configures some
clocks in accordance with this. Boards wishing to make use of nominal
mode will need to override some of the clock rates manually.

As operating the clocks outside of their allowed range can lead to
difficult to debug issues, it makes sense to register the maximum rates
allowed in the driver, so the CCF can take them into account.

[PATCH AUTOSEL 6.6 133/294] ARM: at91: pm: fix at91_suspend_finish for ZQ calibration

[Sasha Levin]

From: Li Bin <bin.li@microchip.com>

[ Upstream commit bc4722c3598d0e2c2dbf9609a3d3198993093e2b ]

For sama7g5 and sama7d65 backup mode, we encountered a "ZQ calibrate error"
during recalibrating the impedance in BootStrap.
We found that the impedance value saved in at91_suspend_finish() before
the DDR entered self-refresh mode did not match the resistor values. The
ZDATA field in the DDR3PHY_ZQ0CR0 register uses a modified gray code to
select the different impedance setting.
But these gray code are incorrect, a workaournd from design team fixed the
bug in the calibration logic. The ZDATA contains four independent impedance
elements, but the algorithm combined the four elements into one. The elements
were fixed using properly shifted offsets.

[PATCH AUTOSEL 6.6 134/294] drm/mediatek: mtk_dpi: Add checks for reg_h_fre_con existence

[Sasha Levin]

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>

[ Upstream commit 8c9da7cd0bbcc90ab444454fecf535320456a312 ]

In preparation for adding support for newer DPI instances which
do support direct-pin but do not have any H_FRE_CON register,
like the one found in MT8195 and MT8188, add a branch to check
if the reg_h_fre_con variable was declared in the mtk_dpi_conf
structure for the probed SoC DPI version.

As a note, this is useful specifically only for cases in which
the support_direct_pin variable is true, so mt8195-dpintf is
not affected by any issue.

[PATCH AUTOSEL 6.6 137/294] soc: apple: rtkit: Use high prio work queue

[Sasha Levin]

From: Janne Grunau <j@jannau.net>

[ Upstream commit 22af2fac88fa5dbc310bfe7d0b66d4de3ac47305 ]

rtkit messages as communication with the DCP firmware for framebuffer
swaps or input events are time critical so use WQ_HIGHPRI to prevent
user space CPU load to increase latency.
With kwin_wayland 6's explicit sync mode user space load was able to
delay the IOMFB rtkit communication enough to miss vsync for surface
swaps. Minimal test scenario is constantly resizing a glxgears
Xwayland window.

From: Hector Martin <marcan@marcan.st>

[ Upstream commit a06398687065e0c334dc5fc4d2778b5b87292e43 ]

Apparently nobody can figure out where the old logic came from, but it
seems like it has never been actually used on any supported firmware to
this day. OSLog buffers were apparently never requested.

But starting with 13.3, we actually need this implemented properly for
MTP (and later AOP) to work, so let's actually do that.

[PATCH AUTOSEL 6.6 148/294] net: ethernet: mtk_ppe_offload: Allow QinQ, double ETH_P_8021Q only

[Sasha Levin]

From: Eric Woudstra <ericwouds@gmail.com>

[ Upstream commit 7fe0353606d77a32c4c7f2814833dd1c043ebdd2 ]

mtk_foe_entry_set_vlan() in mtk_ppe.c already supports double vlan
tagging, but mtk_flow_offload_replace() in mtk_ppe_offload.c only allows
for 1 vlan tag, optionally in combination with pppoe and dsa tags.

However, mtk_foe_entry_set_vlan() only allows for setting the vlan id.
The protocol cannot be set, it is always ETH_P_8021Q, for inner and outer
tag. This patch adds QinQ support to mtk_flow_offload_replace(), only in
the case that both inner and outer tags are ETH_P_8021Q.

Only PPPoE-in-Q (as before) and Q-in-Q are allowed. A combination
of PPPoE and Q-in-Q is not allowed.

[PATCH AUTOSEL 6.6 152/294] soc: ti: k3-socinfo: Do not use syscon helper to build regmap

[Sasha Levin]

From: Andrew Davis <afd@ti.com>

[ Upstream commit a5caf03188e44388e8c618dcbe5fffad1a249385 ]

The syscon helper device_node_to_regmap() is used to fetch a regmap
registered to a device node. It also currently creates this regmap
if the node did not already have a regmap associated with it. This
should only be used on "syscon" nodes. This driver is not such a
device and instead uses device_node_to_regmap() on its own node as
a hacky way to create a regmap for itself.

This will not work going forward and so we should create our regmap
the normal way by defining our regmap_config, fetching our memory
resource, then using the normal regmap_init_mmio() function.

[PATCH AUTOSEL 6.6 157/294] ASoC: mediatek: mt8188: Treat DMIC_GAINx_CUR as non-volatile

[Sasha Levin]

From: Nícolas F. R. A. Prado <nfraprado@collabora.com>

[ Upstream commit 7d87bde21c73731ddaf15e572020f80999c38ee3 ]

The DMIC_GAINx_CUR registers contain the current (as in present) gain of
each DMIC. During capture, this gain will ramp up until a target value
is reached, and therefore the register is volatile since it is updated
automatically by hardware.

However, after capture the register's value returns to the value that
was written to it. So reading these registers returns the current gain,
and writing configures the initial gain for every capture.

>From an audio configuration perspective, reading the instantaneous gain
is not really useful. Instead, reading back the initial gain that was
configured is the desired behavior. For that reason, consider the
DMIC_GAINx_CUR registers as non-volatile, so the regmap's cache can be
used to retrieve the values, rather than requiring pm runtime resuming
the device.

[PATCH AUTOSEL 6.6 186/294] serial: mctrl_gpio: split disable_ms into sync and no_sync APIs

The following splat has been observed on a SAMA5D27 platform using

This warning is emitted when trying to toggle, at the highest level,
some flow control (with serdev_device_set_flow_control) in a device
driver. At the lowest level, the atmel_serial driver is using
serial_mctrl_gpio lib to enable/disable the corresponding IRQs
accordingly.  The warning emitted by CONFIG_DEBUG_ATOMIC_SLEEP is due to
disable_irq (called in mctrl_gpio_disable_ms) being possibly called in
some atomic context (some tty drivers perform modem lines configuration
in regions protected by port lock).

Split mctrl_gpio_disable_ms into two differents APIs, a non-blocking one
and a blocking one. Replace mctrl_gpio_disable_ms calls with the
relevant version depending on whether the call is protected by some port
lock.

[PATCH AUTOSEL 6.6 188/294] pmdomain: imx: gpcv2: use proper helper for property detection

[Sasha Levin]

From: Ahmad Fatoum <a.fatoum@pengutronix.de>

[ Upstream commit 6568cb40e73163fa25e2779f7234b169b2e1a32e ]

Starting with commit c141ecc3cecd7 ("of: Warn when of_property_read_bool()
is used on non-boolean properties"), probing the gpcv2 device on i.MX8M
SoCs leads to warnings when LOCKDEP is enabled.

Fix this by checking property presence with of_property_present as
intended.

[PATCH AUTOSEL 6.6 198/294] firmware: arm_ffa: Reject higher major version as incompatible

[Sasha Levin]

From: Sudeep Holla <sudeep.holla@arm.com>

[ Upstream commit efff6a7f16b34fd902f342b58bd8bafc2d6f2fd1 ]

When the firmware compatibility was handled previously in the commit
8e3f9da608f1 ("firmware: arm_ffa: Handle compatibility with different firmware versions"),
we only addressed firmware versions that have higher minor versions
compared to the driver version which is should be considered compatible
unless the firmware returns NOT_SUPPORTED.

However, if the firmware reports higher major version than the driver
supported, we need to reject it. If the firmware can work in a compatible
mode with the driver requested version, it must return the same major
version as requested.

[ Upstream commit 385a59e7f7fb3438466a0712cc14672c708bbd57 ]

Add clock-output-names property to clock nodes, so that the resulting
clock name do not change when clock node name is changed.
Also, replace underscores with hyphens in the clock node names as per
dt-schema rule.

[PATCH AUTOSEL 6.6 278/294] firmware: arm_scmi: Relax duplicate name constraint across protocol ids

[Sasha Levin]

From: Sudeep Holla <sudeep.holla@arm.com>

[ Upstream commit 21ee965267bcbdd733be0f35344fa0f0226d7861 ]

Currently in scmi_protocol_device_request(), no duplicate scmi device
name is allowed across any protocol. However scmi_dev_match_id() first
matches the protocol id and then the name. So, there is no strict
requirement to keep this scmi device name unique across all the protocols.

Relax the constraint on the duplicate name across the protocols and
inhibit only within the same protocol id.

[PATCH AUTOSEL 6.6 284/294] spi: zynqmp-gqspi: Always acknowledge interrupts

From: Sean Anderson <sean.anderson@linux.dev>

[ Upstream commit 89785306453ce6d949e783f6936821a0b7649ee2 ]

RXEMPTY can cause an IRQ, even though we may not do anything about it
(such as if we are waiting for more received data). We must still handle
these IRQs because we can tell they were caused by the device.
