[PATCH AUTOSEL 5.3 01/81] regulator: of: fix suspend-min/max-voltage parsing

[Sasha Levin]

From: Marco Felsch <m.felsch@pengutronix.de>

[ Upstream commit 131cb1210d4b58acb0695707dad2eb90dcb50a2a ]

Currently the regulator-suspend-min/max-microvolt must be within the
root regulator node but the dt-bindings specifies it as subnode
properties for the regulator-state-[mem/disk/standby] node. The only DT
using this bindings currently is the at91-sama5d2_xplained.dts and this
DT uses it correctly. I don't know if it isn't tested but it can't work
without this fix.

[PATCH AUTOSEL 5.3 03/81] ASoC: wm8994: Do not register inapplicable controls for WM1811

[Sasha Levin]

From: Sylwester Nawrocki <s.nawrocki@samsung.com>

[ Upstream commit ca2347190adb5e4eece73a2b16e96e651c46246b ]

In case of WM1811 device there are currently being registered controls
referring to registers not existing on that device.
It has been noticed when getting values of "AIF1ADC2 Volume", "AIF1DAC2
Volume" controls was failing during ALSA state restoring at boot time:
 "amixer: Mixer hw:0 load error: Device or resource busy"

Reading some registers through I2C was failing with EBUSY error and
indeed these registers were not available according to the datasheet.

To fix this controls not available on WM1811 are moved to a separate
array and registered only for WM8994 and WM8958.

There are some further differences between WM8994 and WM1811,
e.g. registers 603h, 604h, 605h, which are not covered in this patch.

[PATCH AUTOSEL 5.3 04/81] regulator: da9062: fix suspend_enable/disable preparation

[Sasha Levin]

From: Marco Felsch <m.felsch@pengutronix.de>

[ Upstream commit a72865f057820ea9f57597915da4b651d65eb92f ]

Currently the suspend reg_field maps to the pmic voltage selection bits
and is used during suspend_enabe/disable() and during get_mode(). This
seems to be wrong for both use cases.

Use case one (suspend_enabe/disable):
Those callbacks are used to mark a regulator device as enabled/disabled
during suspend. Marking the regulator enabled during suspend is done by
the LDOx_CONF/BUCKx_CONF bit within the LDOx_CONT/BUCKx_CONT registers.
Setting this bit tells the DA9062 PMIC state machine to keep the
regulator on in POWERDOWN mode and switch to suspend voltage.

Use case two (get_mode):
The get_mode callback is used to retrieve the active mode state. Since
the regulator-setting-A is used for the active state and
regulator-setting-B for the suspend state there is no need to check
which regulator setting is active.

The "template.id" variable is an enum and in this context GCC will
treat it as an unsigned int so it can never be less than zero.

[PATCH AUTOSEL 5.3 06/81] arm64: dts: allwinner: a64: pine64-plus: Add PHY regulator delay

[Sasha Levin]

From: Jernej Skrabec <jernej.skrabec@siol.net>

[ Upstream commit 2511366797fa6ab4a404b4b000ef7cd262aaafe8 ]

Depending on kernel and bootloader configuration, it's possible that
Realtek ethernet PHY isn't powered on properly. According to the
datasheet, it needs 30ms to power up and then some more time before it
can be used.

Fix that by adding 100ms ramp delay to regulator responsible for
powering PHY.

[PATCH AUTOSEL 5.3 07/81] arm64: dts: allwinner: a64: Drop PMU node

[Sasha Levin]

From: Vasily Khoruzhick <anarsoul@gmail.com>

[ Upstream commit ed3e9406bcbc32f84dc4aa4cb4767852e5ab086c ]

Looks like PMU in A64 is broken, it generates no interrupts at all and
as result 'perf top' shows no events.

Tested on Pine64-LTS.

[PATCH AUTOSEL 5.3 08/81] arm64: dts: allwinner: a64: sopine-baseboard: Add PHY regulator delay

[Sasha Levin]

From: Jernej Skrabec <jernej.skrabec@siol.net>

[ Upstream commit ccdf3aaa27ded6db9a93eed3ca7468bb2353b8fe ]

It turns out that sopine-baseboard needs same fix as pine64-plus
for ethernet PHY. Here too Realtek ethernet PHY chip needs additional
power on delay to properly initialize. Datasheet mentions that chip
needs 30 ms to be properly powered on and that it needs some more time
to be initialized.

Fix that by adding 100ms ramp delay to regulator responsible for
powering PHY.

Note that issue was found out and fix tested on pine64-lts, but it's
basically the same as sopine-baseboard, only layout and connectors
differ.

[PATCH AUTOSEL 5.3 10/81] regulator: ti-abb: Fix timeout in ti_abb_wait_txdone/ti_abb_clear_all_txdone

[Sasha Levin]

From: Axel Lin <axel.lin@ingics.com>

[ Upstream commit f64db548799e0330897c3203680c2ee795ade518 ]

ti_abb_wait_txdone() may return -ETIMEDOUT when ti_abb_check_txdone()
returns true in the latest iteration of the while loop because the timeout
value is abb->settling_time + 1. Similarly, ti_abb_clear_all_txdone() may
return -ETIMEDOUT when ti_abb_check_txdone() returns false in the latest
iteration of the while loop. Fix it.

[PATCH AUTOSEL 5.3 11/81] pinctrl: intel: Allocate IRQ chip dynamic

[Sasha Levin]

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

[ Upstream commit 57ff2df1b952c7934d7b0e1d3a2ec403ec76edec ]

Keeping the IRQ chip definition static shares it with multiple instances of
the GPIO chip in the system. This is bad and now we get this warning from
GPIO library:

"detected irqchip that is shared with multiple gpiochips: please fix the driver."

Hence, move the IRQ chip definition from being driver static into the struct
intel_pinctrl. So a unique IRQ chip is used for each GPIO chip instance.

Fixes: ee1a6ca43dba ("pinctrl: intel: Add Intel Broxton pin controller support")
Depends-on: 5ff56b015e85 ("pinctrl: intel: Disable GPIO pin interrupts in suspend")

[PATCH AUTOSEL 5.3 12/81] ASoC: SOF: loader: fix kernel oops on firmware boot failure

[Sasha Levin]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

[ Upstream commit 798614885a0e1b867ceb0197c30c2d82575c73b0 ]

When we fail to boot the firmware, we encounter a kernel oops in
hda_dsp_get_registers(), which is called conditionally in
hda_dsp_dump() when the sdev_>boot_complete flag is set.

Setting this flag _after_ dumping the data fixes the issue and does
not change the programming flow.

[PATCH AUTOSEL 5.3 14/81] ASoC: SOF: Intel: hda: fix warnings during FW load

[Sasha Levin]

From: Kai Vehmanen <kai.vehmanen@linux.intel.com>

[ Upstream commit 4ff5f6439fe69624e8f7d559915e9b54a6477684 ]

The "snd_pcm_substream" handle was not initialized properly
in hda-loader.c for firmware load.

When the HDA DMAs were used to load the firmware,
the interrupts related to firmware load also triggered
calls to snd_sof_pcm_period_elapsed() on a non-existent ALSA
PCM stream.

This caused runtime kernel warnings from
pcm_lib.c:snd_pcm_period_elapsed().

[PATCH AUTOSEL 5.3 16/81] ASoC: SOF: Intel: hda: Disable DMI L1 entry during capture

From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

[ Upstream commit 43b2ab9009b13bfff47fcc1893de9244b39bdd54 ]

There is a known issue on some Intel platforms which causes
pause/release to run into xrun's during capture usecases.
The suggested workaround to address the issue is to
disable the entry of lower power L1 state in the physical
DMI link when there is a capture stream open.

[PATCH AUTOSEL 5.3 23/81] arm64: dts: rockchip: fix Rockpro64 RK808 interrupt line

[Sasha Levin]

From: Hugh Cole-Baker <sigmaris@gmail.com>

[ Upstream commit deea9f5fc32040fd6f6132f2260ba410fb5cf98c ]

Fix the pinctrl and interrupt specifier for RK808 to use GPIO3_B2. On the
Rockpro64 schematic [1] page 16, it shows GPIO3_B2 used for the interrupt
line PMIC_INT_L from the RK808, and there's a note which translates as:
"PMU termination GPIO1_C5 changed to this".

Tested by setting an RTC wakealarm and checking /proc/interrupts counters.
Without this patch, neither the rockchip_gpio_irq counter for the RK808,
nor the RTC alarm counter increment when the alarm time is reached.
With this patch, both interrupt counters increment by 1 as expected.

[PATCH AUTOSEL 5.3 25/81] arm64: dts: rockchip: fix RockPro64 vdd-log regulator settings

[Sasha Levin]

From: Soeren Moch <smoch@web.de>

[ Upstream commit 0990c5e7573098117c69651821647c228483e31b ]

The RockPro64 schematic [1] page 18 states a min voltage of 0.8V and a
max voltage of 1.4V for the VDD_LOG pwm regulator. However, there is an
additional note that the pwm parameter needs to be modified.
From the schematics a voltage range of 0.8V to 1.7V can be calculated.
Additional voltage measurements on the board show that this fix indeed
leads to the correct voltage, while without this fix the voltage was set
too high.

The RockPro64 schematics [1], [2] show that the rk3399 EMMC_STRB pin is
connected to the RESET pin instead of the DATA_STROBE pin of the eMMC module.
So the data strobe cannot be used for its intended purpose on this board,

[PATCH AUTOSEL 5.3 29/81] arm64: dts: zii-ultra: fix ARM regulator states

[Sasha Levin]

From: Lucas Stach <l.stach@pengutronix.de>

[ Upstream commit 21094ba5c1f4b15df096e8f6247a50b6ab57c869 ]

The GPIO controlled regulator for the ARM power supply is supplying
the higher voltage when the GPIO is driven high. This is opposite to
the similar regulator setup on the EVK board and is impacting stability
of the board as the ARM domain has been supplied with a too low voltage
when to faster OPPs are in use.

[PATCH AUTOSEL 5.3 30/81] ARM: dts: am3874-iceboard: Fix 'i2c-mux-idle-disconnect' usage

[Sasha Levin]

From: Andrey Smirnov <andrew.smirnov@gmail.com>

[ Upstream commit 647c8977e111c0a62c93a489ebc4b045c833fdb4 ]

According to
Documentation/devicetree/bindings/i2c/i2c-mux-pca954x.txt,
i2c-mux-idle-disconnect is a property of a parent node since it
pertains to the mux/switch as a whole, so move it there and drop all
of the concurrences in child nodes.

[PATCH AUTOSEL 5.3 33/81] ARM: dts: Use level interrupt for omap4 & 5 wlcore

[Sasha Levin]

From: Tony Lindgren <tony@atomide.com>

[ Upstream commit 087a2b7ec973f6f30f6e7b72cb50b6f7734ffdd2 ]

Commit 572cf7d7b07d ("ARM: dts: Improve omap l4per idling with wlcore edge
sensitive interrupt") changed wlcore interrupts to use edge interrupt based
on what's specified in the wl1835mod.pdf data sheet.

However, there are still cases where we can have lost interrupts as
described in omap_gpio_unidle(). And using a level interrupt instead of edge
interrupt helps as we avoid the check for untriggered GPIO interrupts in
omap_gpio_unidle().

And with commit e6818d29ea15 ("gpio: gpio-omap: configure edge detection
for level IRQs for idle wakeup") GPIOs idle just fine with level interrupts.

Let's change omap4 and 5 wlcore users back to using level interrupt
instead of edge interrupt. Let's not change the others as I've only seen
this on omap4 and 5, probably because the other SoCs don't have l4per idle
independent of the CPUs.

[PATCH AUTOSEL 5.3 34/81] ARM: mm: fix alignment handler faults under memory pressure

[Sasha Levin]

From: Russell King <rmk+kernel@armlinux.org.uk>

[ Upstream commit 67e15fa5b487adb9b78a92789eeff2d6ec8f5cee ]

When the system has high memory pressure, the page containing the
instruction may be paged out.  Using probe_kernel_address() means that
if the page is swapped out, the resulting page fault will not be
handled because page faults are disabled by this function.

Use get_user() to read the instruction instead.

[PATCH AUTOSEL 5.3 36/81] scsi: scsi_dh_alua: handle RTPG sense code correctly during state transitions

[Sasha Levin]

From: Hannes Reinecke <hare@suse.com>

[ Upstream commit b6ce6fb121a655aefe41dccc077141c102145a37 ]

Some arrays are not capable of returning RTPG data during state
transitioning, but rather return an 'LUN not accessible, asymmetric access
state transition' sense code. In these cases we can set the state to
'transitioning' directly and don't need to evaluate the RTPG data (which we
won't have anyway).

[PATCH AUTOSEL 5.3 39/81] ARM: 8908/1: add __always_inline to functions called from __get_user_check()

[Sasha Levin]

From: Masahiro Yamada <yamada.masahiro@socionext.com>

[ Upstream commit 851140ab0d083c78e5723a8b1cbd258f567a7aff ]

KernelCI reports that bcm2835_defconfig is no longer booting since
commit ac7c3e4ff401 ("compiler: enable CONFIG_OPTIMIZE_INLINING
forcibly") (https://lkml.org/lkml/2019/9/26/825).

I also received a regression report from Nicolas Saenz Julienne
(https://lkml.org/lkml/2019/9/27/263).

This problem has cropped up on bcm2835_defconfig because it enables
CONFIG_CC_OPTIMIZE_FOR_SIZE. The compiler tends to prefer not inlining
functions with -Os. I was able to reproduce it with other boards and
defconfig files by manually enabling CONFIG_CC_OPTIMIZE_FOR_SIZE.

The __get_user_check() specifically uses r0, r1, r2 registers.
So, uaccess_save_and_enable() and uaccess_restore() must be inlined.
Otherwise, those register assignments would be entirely dropped,
according to my analysis of the disassembly.

Prior to commit 9012d011660e ("compiler: allow all arches to enable
CONFIG_OPTIMIZE_INLINING"), the 'inline' marker was always enough for
inlining functions, except on x86.

Since that commit, all architectures can enable CONFIG_OPTIMIZE_INLINING.
So, __always_inline is now the only guaranteed way of forcible inlining.

I added __always_inline to 4 functions in the call-graph from the
__get_user_check() macro.

Fixes: 9012d011660e ("compiler: allow all arches to enable CONFIG_OPTIMIZE_INLINING")

[PATCH AUTOSEL 5.3 40/81] ARM: 8914/1: NOMMU: Fix exc_ret for XIP

[Sasha Levin]

From: Vladimir Murzin <vladimir.murzin@arm.com>

[ Upstream commit 4c0742f65b4ee466546fd24b71b56516cacd4613 ]

It was reported that 72cd4064fcca "NOMMU: Toggle only bits in
EXC_RETURN we are really care of" breaks NOMMU+XIP combination.
It happens because saved EXC_RETURN gets overwritten when data
section is relocated.

The fix is to propagate EXC_RETURN via register and let relocation
code to commit that value into memory.

[PATCH AUTOSEL 5.3 44/81] ARM: dts: imx6q-logicpd: Re-Enable SNVS power key

[Sasha Levin]

From: Adam Ford <aford173@gmail.com>

[ Upstream commit 52f4d4043d1edc4e9e66ec79cae3e32cfe0e44d6 ]

A previous patch disabled the SNVS power key by default which
breaks the ability for the imx6q-logicpd board to wake from sleep.
This patch re-enables this feature for this board.

From: Dan Carpenter <dan.carpenter@oracle.com>

[ Upstream commit fd47a417e75e2506eb3672ae569b1c87e3774155 ]

The problem is that sizeof() is unsigned long so negative error codes

[PATCH AUTOSEL 5.3 52/81] 8250-men-mcb: fix error checking when get_num_ports returns -ENODEV

[Sasha Levin]

From: Colin Ian King <colin.king@canonical.com>

[ Upstream commit f50b6805dbb993152025ec04dea094c40cc93a0c ]

The current checking for failure on the number of ports fails when
-ENODEV is returned from the call to get_num_ports. Fix this by making
num_ports and loop counter i signed rather than unsigned ints. Also
add check for num_ports being less than zero to check for -ve error
returns.

From: Bodo Stroesser <bstroesser@ts.fujitsu.com>

[ Upstream commit 27e84243cb63601a10e366afe3e2d05bb03c1cb5 ]

passthrough_parse_cdb() - used by TCMU and PSCSI - attepts to reset the LUN
field of SCSI-2 CDBs (bits 5,6,7 of byte 1).  The current code is wrong as
for newer commands not having the LUN field it overwrites relevant command
bits (e.g. for SECURITY PROTOCOL IN / OUT). We think this code was
unnecessary from the beginning or at least it is no longer useful. So we
remove it entirely.

All the kcontrol put() functions are currently returning 0 when

not seem to get notified on SND_CTL_EVENT_MASK_VALUE callbacks

This patch fixes that by returning true for volume, switch
and enum type kcontrols when values do change in put().

[PATCH AUTOSEL 5.3 61/81] tracing: Fix "gfp_t" format for synthetic events

[Sasha Levin]

From: Zhengjun Xing <zhengjun.xing@linux.intel.com>

[ Upstream commit 9fa8c9c647be624e91b09ecffa7cd97ee0600b40 ]

In the format of synthetic events, the "gfp_t" is shown as "signed:1",
but in fact the "gfp_t" is "unsigned", should be shown as "signed:0".

The issue can be reproduced by the following commands:

echo 'memlatency u64 lat; unsigned int order; gfp_t gfp_flags; int migratetype' > /sys/kernel/debug/tracing/synthetic_events

[PATCH AUTOSEL 5.3 62/81] ARM: dts: bcm2837-rpi-cm3: Avoid leds-gpio probing issue

[Sasha Levin]

From: Stefan Wahren <wahrenst@gmx.net>

[ Upstream commit 626c45d223e22090511acbfb481e0ece1de1356d ]

bcm2835-rpi.dtsi defines the behavior of the ACT LED, which is available
on all Raspberry Pi boards. But there is no driver for this particual
GPIO on CM3 in mainline yet, so this node was left incomplete without
the actual GPIO definition. Since commit 025bf37725f1 ("gpio: Fix return
value mismatch of function gpiod_get_from_of_node()") this causing probe
issues of the leds-gpio driver for users of the CM3 dtsi file.

  leds-gpio: probe of leds failed with error -2

Until we have the necessary GPIO driver hide the ACT node for CM3
to avoid this.

[PATCH AUTOSEL 5.3 63/81] i2c: aspeed: fix master pending state handling

[Sasha Levin]

From: Jae Hyun Yoo <jae.hyun.yoo@linux.intel.com>

[ Upstream commit 1f0d9cbeec9bb0a1c2013342836f2c9754d6502b ]

In case of master pending state, it should not trigger a master
command, otherwise data could be corrupted because this H/W shares
the same data buffer for slave and master operations. It also means
that H/W command queue handling is unreliable because of the buffer
sharing issue. To fix this issue, it clears command queue if a
master command is queued in pending state to use S/W solution
instead of H/W command queue handling. Also, it refines restarting
mechanism of the pending master command.
