"program" mode on this controller can trigger up to 56 bits of data
shifting. During the operation, data in PRGDATA[0-5] will be
shifted out from MOSI, and data from MISO will be continuously filling
SHREG[0-9].
Currently this mode is used to implement transfer_one_message for 6-byte
full-duplex transfer, but it can execute a transfer for up-to 7 bytes
as long as the last byte is read only.
transfer_one_message is expected to perform full-duplex transfer,
instead of transfer with specific format. mtk_nor_spi_mem_prg is
added here to use this extra byte.
Newer version of this controller can trigger longer data shifting with
shift bytes more than PRGDATA_MAX + SHREG_MAX. This patch is implemented
with that in mind and it checks against both SHREG_MAX and PRG_CNT_MAX
for future support of new controllers.

Add support for new device: the TI bq34z100-G1, a Wide Range Fuel Gauge
for Li-Ion, PbA, NiMH, and NiCd batteries. The device shares a lot with
other models, although it has its own differences requiring new quirks.
This patch was tested on a system equipped with NiMH batteries.

bq27000, bq27010 and upcoming bq34z100 have a Capacity Inaccurate flag.
However except this similarity, bq34z100 is quite different than
bq27000/bq27010, so flag BQ27XXX_O_ZERO cannot be reused here. Add
a new bit flag describing this capability.

Some TIS based TPMs can return 0xff to status reads if the locality
hasn't been properly requested. Detect this condition by checking the

When fitted, the SynQuacer platform exposes its SPI TPM via a MMIO
window that is backed by the SPI command sequencer in the SPI bus
controller. This arrangement has the limitation that only byte size

that take this into account.

This patch series enables support for the regulators as found in
the PM660 and PM660L PMICs.
While at it, and to make them work, along with other regulators
for other qcom PMICs, enlarge the maximum property name length in
the regulator core, so that we're able to correctly parse the
supply parents, which have got very long names (details in patch 1/5).
This patch series has been tested against the following devices:

- Sony Xperia 10 (SDM630 Ganges Kirin)
- Sony Xperia 10 Plus (SDM636 Ganges Mermaid)

The only usage of qcom_labibb_ops is to assign it to the ops field in
the regulator_desc struct, which is a const pointer. The only usage of
pmi8998_lab_desc and pmi8998_ibb_desc is to assign their address to the
desc field in the labibb_regulator_data struct which can be made const,
since it is only copied into the desc field in the
labbibb_regulator_data struct. This struct is modified, but that's a
copy of the static one. Make them const to allow the compiler to put
them in read-only memory.

The PM660 and PM660L are a very very common PMIC combo, found on
boards using the SDM630, SDM636, SDM660 (and SDA variants) SoC.
PM660 provides 6 SMPS and 19 LDOs (of which one is unaccesible),
while PM660L provides 5 SMPS (of which S3 and S4 are combined),
10 LDOs and a Buck-or-Boost (BoB) regulator.
The PM660L IC also provides other regulators that are very
specialized (for example, for the display) and will be managed
in the other appropriate drivers (for example, labibb).

The PM660 PMIC is very often paired with the PM660L option on
SDM630/663/660 (and SDA variants) boards.
The PM660 has 11 "660" LDOs (2 NMOS, 9 PMOS) and 7 HT LDOs (4 NMOS,
3 PMOS) and a quirk: the L4 regulator is unaccessible or does not
exist on the PMIC.
The PM660L has 8 "660" LDOs (1 NMOS, 7 PMOS) and 2 HT NMOS LDOs.

Some regulator drivers may be defining very long names: this is the
case with the qcom_smd and qcom_spmi regulators, where we need to
parse the regulator parents from DT.
For clarity, this is an example:
{ "l13a", QCOM_SMD_RPM_LDOA, 13, &pm660_ht_lvpldo,
"vdd_l8_l9_l10_l11_l12_l13_l14" },
pm660-regulators {
...
vdd_l8_l9_l10_l11_l12_l13_l14-supply = <&vreg_s4a_2p04>
...
};
Now, with a 32 characters limit, the function is trying to parse,
exactly, "vdd_l8_l9_l10_l11_l12_l13_l14-s" (32 chars) instead of
the right one, which is 37 chars long in this specific case.
... And this is not only the case with PM660/PM660L, but also with
PMA8084, PM8916, PM8950 and others that are not implemented yet.
The length of 64 chars was chosen based on the longest parsed property
name that I could find, which is in PM8916, and would be 53 characters
long.
At that point, rounding that to 64 looked like being the best idea.

Some EtherAVB variants support internal clock delay configuration, which
can add larger delays than the delays that are typically supported by
the PHY (using an "rgmii-*id" PHY mode, and/or "[rt]xc-skew-ps"
properties).
Historically, the EtherAVB driver configured these delays based on the
"rgmii-*id" PHY mode. This caused issues with PHY drivers that
implement PHY internal delays properly[1]. Hence a backwards-compatible
workaround was added by masking the PHY mode[2].
Add proper support for explicit configuration of the MAC internal clock
delays using the new "[rt]x-internal-delay-ps" properties.
Fall back to the old handling if none of these properties is present.

The gain from this option is that the device page table can be aligned

Move to use hmm_range_fault() instead of get_user_pags_remote() to improve
performance in a few aspects:
This includes:
- Dropping the need to allocate and free memory to hold its output
- No need any more to use put_page() to unpin the pages
- The logic to detect contiguous pages is done based on the returned
order, no need to run per page and evaluate.
In addition, moving to use hmm_range_fault() enables to reduce page faults
in the system with it's snapshot mode, this will be introduced in next
patches from this series.
As part of this, cleanup some flows and use the required data structures
to work with hmm_range_fault().

To enable shadow register access, host needs to pass shadow
register configuration to firmware via qmi message. Host also
needs to update ring's HP or TP address to shadow register
address. The write operation to shadow register will be
forwarded to target register by hardware automatically, and
the write operation to shadow register is permitted even
when the target is in power save or sleep mode.
Update the shadow config whenever power up happens.
This feature is controlled by hw parameter supports_shadow_regs which is only

With QCA6390 when doing rmmod the kernel crashed. The reason was that the
destroy functions ath11k_debugfs_pdev_destroy() and ath11k_debugfs_soc_destroy()
accidentally had swapped the debugfs directories and
ath11k_debugfs_soc_destroy() was removing an already removed directory, which
crashed the kernel.
The source of confusion is badly named function and variable names. I think the

For QCA6390 we first need to call free_irq() and only then disable_msi(). Otherwise a
kernel BUG below will happen. Also free core, hal_srng and ce resources during
ath11k_pci_remove().

Add packet log support for QCA6390, otherwise the data connection will stall
within a minute or so. Enable it via debugfs and use trace-cmd to capture the
pktlogs.
echo 0xffff 1 > /sys/kernel/debug/ath11k/qca6390\ hw2.0/mac0/pktlog_filter
The mon status ring doesn't support interrupt so far, so host starts
a timer to reap this ring. The timer handler also reaps the
rxdma_err_dst_ring in case of monitor mode.
As QCA6390 requires bss created ahead of starting vdev, so check
vdev_start_delay for monitor mode.
For QCA6390, it uses wbm_desc_rel_ring to return descriptors.
It also uses rx_refill_buf_ring to fill mon buffer instead of
rxdma_mon_buf_ring.

QCA6390 does not support monitor mode at the moment so disable it altogether,
using a hack as mac80211 does not support disabling it otherwise. Add a boolean
to hw_params to know if hardware supports monitor mode.
IPQ8074 continues to support monitor mode normally.

There are different versions of QCA6390. Check TCSR_SOC_HW_VERSION to make sure
that the device is hw2.0, all the rest are unsupported.
This needs to be checked after ath11k_pci_claim() so move the whole switch choosing hw_ver.

As QCA6390 does not support mesh interfaces, move the interface_modes to
hw_params. Also create interface combinations dynamically so that it's easy to
change the values.
Now QCA6390 does not claim to support mesh interfaces to user space, but
IPQ8074 continues to do that.

For QCA6390, station vdev needs to delay startup but not for AP mode. On AP
mode vdev starts up immediately after bss peer is created in chanctx assignment
context.
This patch does not affect IPQ8074 family of devices.

The QCA6390 board I have, model 8291M-PR comes with an ELF board file. To get
this to at least somewhat work, I renamed bdwlan.e04 to 'board.bin' and then
added this patch to check for ELF magic string in the beginning of the file.
If that is found, use type ELF. After this the driver loads.
