The Meson SDIO controller uses the DAT0 lane for hardware busy
detection. Set MMC_CAP_WAIT_WHILE_BUSY accordingly. This fixes
the following error observed with Linux 5.7 (pre-rc-1):

tidss uses devm_kzalloc to allocate DRM plane, encoder and crtc objects.
This is not correct as the lifetime of those objects should be longer
than the underlying device's.
When unloading tidss module, the devm_kzalloc'ed objects have already
been freed when tidss_release() is called, and the driver will accesses
freed memory possibly causing a crash, a kernel WARN, or other undefined
behavior, and also KASAN will give a bug.

When the 'spi_device_id' table was removed, it omitted to cleanup/fix the
assignment:
'indio_dev->name = spi_get_device_id(spi)->name;'
After that patch 'spi_get_device_id(spi)' returns NULL, so this crashes
during probe with null de-ref.
This change fixes this by introducing an ad7192_chip_info struct, and
defines all part-names [that should be assigned to indio_dev->name] in a
'ad7192_chip_info_tbl' table.
With this change, the old 'st->devid' is also moved to be a
'chip_info->chip_id'. And the old 'ID_AD719X' macros have been renamed to
'CHIPID_AD719X'. Tld identifiers have been re-purposed to be enum/index
values in the new 'ad7192_chip_info_tbl'.
This should fix the bug, and maintain the ABI for the 'indio_dev->name'
field.

Suspend/resume were not working correctly with pm runtime.
Now suspend check if the chip is already suspended, and
resume put runtime pm in the correct state.
Issues seen prior to this were:
When entering suspend, there was an error in logs because we
were disabling vddio regulator although it was already disabled.
And when resuming, the chip was pull back to full power but the
pm_runtime state was not updated. So it was believing it was
still suspended.

The XADC supports a samplerate of up to 1MSPS. Unfortunately the hardware
does not have a FIFO, which means it generates an interrupt for each
conversion sequence. At one 1MSPS this creates an interrupt storm that
causes the system to soft-lock.
For this reason the driver limits the maximum samplerate to 150kSPS.
Currently this check is only done when setting a new samplerate. But it is
also possible that the initial samplerate configured in the FPGA bitstream
exceeds the limit.
In this case when starting to capture data without first changing the
samplerate the system can overload.
To prevent this check the currently configured samplerate in the probe
function and reduce it to the maximum if necessary.

simultaneous mode
The XADC has two internal ADCs. Depending on the mode it is operating in
either one or both of them are used. The device manual calls this
continuous (one ADC) and simultaneous (both ADCs) mode.
The meaning of the sequencing register for the aux channels changes
depending on the mode.
In continuous mode each bit corresponds to one of the 16 aux channels. And
the single ADC will convert them one by one in order.
In simultaneous mode the aux channels are split into two groups the first 8
channels are assigned to the first ADC and the other 8 channels to the
second ADC. The upper 8 bits of the sequencing register are unused and the
lower 8 bits control both ADCs. This means a bit needs to be set if either
the corresponding channel from the first group or the second group (or
both) are set.
Currently the driver does not have the special handling required for
simultaneous mode. Add it.

When enabling the trigger and unmasking the end-of-sequence (EOS) interrupt
the EOS interrupt should be cleared from the status register. Otherwise it
is possible that it was still set from a previous capture. If that is the
case the interrupt would fire immediately even though no conversion has
been done yet and stale data is being read from the device.
The old code only clears the interrupt if the interrupt was previously
unmasked. Which does not make much sense since the interrupt is always
masked at this point and in addition masking the interrupt does not clear
the interrupt from the status register. So the clearing needs to be done
unconditionally.

In fine adjustement mode, which is the current default, the sub-second
increment register is the number of nanoseconds that will be added to
the clock when the accumulator overflows. At each clock cycle, the
value of the addend register is added to the accumulator.
Currently, we use 20ns = 1e09ns / 50MHz as this value whatever the
frequency of the ptp clock actually is.
The adjustment is then done on the addend register, only incrementing
every X clock cycles X being the ratio between 50MHz and ptp_clock_rate
(addend = 2^32 * 50MHz/ptp_clock_rate).
This causes the following issues :
- In case the frequency of the ptp clock is inferior or equal to 50MHz,
the addend value calculation will overflow and the default
addend value will be set to 0, causing the clock to not work at
all. (For instance, for ptp_clock_rate = 50MHz, addend = 2^32).
- The resolution of the timestamping clock is limited to 20ns while it
is not needed, thus limiting the accuracy of the timestamping to
20ns.
Fix this by setting sub-second increment to 2e09ns / ptp_clock_rate.
It will allow to reach the minimum possible frequency for
ptp_clk_ref, which is 5MHz for GMII 1000Mps Full-Duplex by setting the
sub-second-increment to a higher value. For instance, for 25MHz, it
gives ssinc = 80ns and default_addend = 2^31.
It will also allow to use a lower value for sub-second-increment, thus
improving the timestamping accuracy with frequencies higher than
100MHz, for instance, for 200MHz, ssinc = 10ns and default_addend =
2^31.
v1->v2:
- Remove modifications to the calculation of default addend, which broke
compatibility with clock frequencies for which 2000000000 / ptp_clk_freq
is not an integer.
- Modify description according to discussions.

There are 2 registers to write to enable a ptp ref clock coming from the
fpga.
One that enables the usage of the clock from the fpga for emac0 and emac1
as a ptp ref clock, and the other to allow signals from the fpga to reach
emac0 and emac1.
Currently, if the dwmac-socfpga has phymode set to PHY_INTERFACE_MODE_MII,
PHY_INTERFACE_MODE_GMII, or PHY_INTERFACE_MODE_SGMII, both registers will
be written and the ptp ref clock will be set as coming from the fpga.
Separate the 2 register writes to only enable signals from the fpga to
reach emac0 or emac1 when ptp ref clock is not coming from the fpga.

i2400mu_bus_bm_wait_for_ack() invokes usb_get_urb(), which increases the
refcount of the "notif_urb".
When i2400mu_bus_bm_wait_for_ack() returns, local variable "notif_urb"
becomes invalid, so the refcount should be decreased to keep refcount
balanced.
The issue happens in all paths of i2400mu_bus_bm_wait_for_ack(), which
forget to decrease the refcnt increased by usb_get_urb(), causing a
refcnt leak.
Fix this issue by calling usb_put_urb() before the
i2400mu_bus_bm_wait_for_ack() returns.

Compile-testing the driver can result in a link failure
when CONFIG_SOC_BUS is disabled:
x86_64-linux-ld: drivers/soc/imx/soc-imx8m.o: in function `imx8_soc_init':
soc-imx8m.c:(.init.text+0x28d): undefined reference to `soc_device_register'
Select it from Kconfig, as we do from the other SoC drivers.

A 1024 byte variable on the stack will warn on any 32-bit architecture
during compile-testing, and is generally a bad idea anyway:
fsl/dpio/dpio-service.c: In function 'dpaa2_io_service_enqueue_multiple_desc_fq':
fsl/dpio/dpio-service.c:495:1: error: the frame size of 1032 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
There are currently no callers of this function, so I cannot tell whether
dynamic memory allocation is allowed once callers are added. Change
it to kcalloc for now, if anyone gets a warning about calling this in
atomic context after they start using it, they can fix it later.

Building dpio for 32 bit shows a new compiler warning from converting
a pointer to a u64:
drivers/soc/fsl/dpio/qbman-portal.c: In function 'qbman_swp_enqueue_multiple_desc_direct':
drivers/soc/fsl/dpio/qbman-portal.c:870:14: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
870 | addr_cena = (uint64_t)s->addr_cena;
The variable is not used anywhere, so removing the assignment seems
to be the correct workaround. After spotting what seemed to be
some confusion about address spaces, I ran the file through sparse,
which showed more warnings:
drivers/soc/fsl/dpio/qbman-portal.c:756:42: warning: incorrect type in argument 1 (different address spaces)
drivers/soc/fsl/dpio/qbman-portal.c:756:42: expected void const volatile [noderef] <asn:2> *addr
drivers/soc/fsl/dpio/qbman-portal.c:756:42: got unsigned int [usertype] *[assigned] p
drivers/soc/fsl/dpio/qbman-portal.c:902:42: warning: incorrect type in argument 1 (different address spaces)
drivers/soc/fsl/dpio/qbman-portal.c:902:42: expected void const volatile [noderef] <asn:2> *addr
drivers/soc/fsl/dpio/qbman-portal.c:902:42: got unsigned int [usertype] *[assigned] p
Here, the problem is passing a token from memremap() into __raw_readl(),
which is only defined to work on MMIO addresses but not RAM. Turning
this into a simple pointer dereference avoids this warning as well.

So get rid of the select.

kmemleak reports several memory leaks from devicetree unittest.
This is the fix for problem 5 of 5.
When overlay 'overlay_bad_add_dup_prop' is applied, the apply code
properly detects that a memory leak will occur if the overlay is removed
since the duplicate property is located in a base devicetree node and
reports via printk():
OF: overlay: WARNING: memory leak will occur if overlay removed, property: /testcase-data-2/substation@100/motor-1/rpm_avail
OF: overlay: WARNING: memory leak will occur if overlay removed, property: /testcase-data-2/substation@100/motor-1/rpm_avail
The overlay is removed when the apply code detects multiple changesets
modifying the same property. This is reported via printk():
OF: overlay: ERROR: multiple fragments add, update, and/or delete property /testcase-data-2/substation@100/motor-1/rpm_avail
As a result of this error, the overlay is removed resulting in the
expected memory leak.
Add another device node level to the overlay so that the duplicate
property is located in a node added by the overlay, thus no memory
leak will occur when the overlay is removed.
Thus users of kmemleak will not have to debug this leak in the future.

hinting
It can be confusing to have multiple features within the same driver that
are using the same verbage. As such this patch is creating a union of
free_page_report_cmd_id with free_page_hint_cmd_id so that we can clean-up
the userspace code a bit in terms of readability while maintaining the
functionality of legacy code.
