eca1e56cee iwlwifi: mvm: don't send GEO_TX_POWER_LIMIT to old firmwares
Old firmware versions don't support this command. Sending it
to any firmware before -41.ucode will crash the firmware.

1d6e81a288 usb: renesas_usbhs: add support for RZ/G2E
HS-USB found in RZ/G2E (a.k.a. r8a774c0) is very similar to the
one found in R-Car E3 (a.k.a. r8a77990), as it needs to release
the PLL reset by the UGCTRL register like R-Car E3, therefore add
r8a774c0 support in a similar fashion to what was done for the
r8a77990.

8dc7623bf6 usb: ehci-omap: Fix deferred probe for phy handling
PHY model is being used on omap5 platforms even if port mode
is not OMAP_EHCI_PORT_MODE_PHY. So don't guess if PHY is required
or not based on PHY mode.

If PHY is provided in device tree, it must be required. So, if
devm_usb_get_phy_by_phandle() gives us an error code other
than -ENODEV (no PHY) then error out.

This fixes USB Ethernet on omap5-uevm if PHY happens to
probe after EHCI thus causing a -EPROBE_DEFER.

c3788cd996 usb: roles: Add a description for the class to Kconfig
That makes the USB role switch support option visible and
selectable for the user. The class driver is also moved to
drivers/usb/roles/ directory.

This will fix an issue that we have with the Intel USB role
switch driver on systems that don't have USB Type-C connectors:

Intel USB role switch driver depends on the USB role switch
class as it should, but since there was no way for the user
to enable the USB role switch class, there was also no way
to select that driver. USB Type-C drivers select the USB
role switch class which makes the Intel USB role switch
driver available and therefore hides the problem.

So in practice Intel USB role switch driver was depending on
USB Type-C drivers.

346fc1089e blk-mq: export hctx->type in debugfs instead of sysfs
Now we only export hctx->type via sysfs, and there isn't such info
in hctx entry under debugfs. We often use debugfs only to diagnose
queue mapping issue, so add the support in debugfs.

Queue mapping becomes a bit more complicated after multiple queue
mapping is supported, we may write blktest to verify if queue mapping
is valid based on blk-mq-debugfs.

Given not necessary to export hctx->type twice, so remove the export
from sysfs.

9488585b21 tpm: add support for partial reads
Currently to read a response from the TPM device an application needs
provide big enough buffer for the whole response and read it in one go.
The application doesn't know how big the response it beforehand so it
always needs to maintain a 4K buffer and read the max (4K).
In case if the user of the TSS library doesn't provide big enough
buffer the TCTI spec says that the library should set the required
size and return TSS2_TCTI_RC_INSUFFICIENT_BUFFER error code so that the
application could allocate a bigger buffer and call receive again.
To make it possible in the TSS library, this requires being able to do
partial reads from the driver.
The library would read the 10 bytes header first to get the actual size
of the response from the header, and then read the rest of the response.

This patch adds support for partial reads, i.e. the user can read the
response in one or multiple reads, until the whole response is consumed.
The user can also read only part of the response and ignore
the rest by issuing a new write to send a new command.

ebd1d3b74f powerpc/32: Move the old 6xx -mcpu logic before the TARGET_CPU logic
The code:

TARGET_CPU logic was 64-bit only.

Since commit 0e00a8c9fd ("powerpc: Allow CPU selection
also on PPC32") this logic is no longer acceptable after the TARGET_CPU
specific. It currently appends -mcpu=powerpc at the end of the command
line, after any TARGET_CPU specific:

  gcc -Wp,-MD,init/.do_mounts.o.d ...
    -mcpu=powerpc -mbig-endian -m32 ...

2713fe3715 Revert "iommu/io-pgtable-arm: Check for v7s-incapable systems"
This reverts commit 82db33dc5e.

After the commit 29859aeb8a ("iommu/io-pgtable-arm-v7s: Abort
allocation when table address overflows the PTE"), v7s will return fail
if the page table allocation isn't expected. this PHYS_OFFSET check
is unnecessary now.

And this check may lead to fail. For example, If CONFIG_RANDOMIZE_BASE
is enabled, the "memstart_addr" will be updated randomly, then the
PHYS_OFFSET may be random.

Qcom's implementation of arm,mmu-500 works well with current
arm-smmu driver implementation. Adding a soc specific compatible
along with arm,mmu-500 makes the bindings future safe.

We need r8a774c0 to be whitelisted for SDHI to work on the RZ/G2E,
but we don't care about the revision of the SoC, so just whitelist
the generic part number.

0c204979c6 mmc: core: Cleanup BKOPS support
It's been ~6 years ago since we introduced the BKOPS support for eMMC
cards. The current code is a bit messy and primarily that's because it
prepares to support running BKOPS in an asynchronous mode. However, that
mode has never been fully implemented/enabled. Instead BKOPS is always
executed in synchronously, when the card has reported an urgent BKOPS
level.

For these reasons, let's make the code more readable by dropping the unused
parts. Let's also rename mmc_start_bkops() to mmc_run_bkops(), as to make
it more descriptive.

1217e61544 mmc: core: Drop redundant check in mmc_send_hpi_cmd()
There is no point checking if HPI is supported in mmc_send_hpi_cmd() as
mmc_interrupt_hpi(), which is the only caller, already checks if HPI has
been enabled. Therefore, let's drop the check and the corresponding error
path.
