Now the debugfs files dais/platforms/codecs have a size limit PAGE_SIZE and
the user can not see the whole contents of dai_list/platform_list/codec_list
when they are larger than this limit.
This patch uses seq_file instead to make sure dais/platforms/codecs show the
full contents of dai_list/platform_list/codec_list.

If bcm2835 is configured as bitclock master calling hw_params()
after prepare() fails with EBUSY. This also makes it impossible to
use bcm2835 in full duplex mode.
The error is caused by the split clock setup: clk_set_rate
is called in hw_params, clk_prepare_enable in prepare. As hw_params
doesn't check if the clock was already enabled clk_set_rate
fails with EBUSY.
Fix this by moving clock startup from prepare to hw_params and
let hw_params properly deal with an already set up or enabled
clock.

The armada 3700 SPI controller has support for full-duplex transfers,
but it can only be done without using the hardware FIFOs.
A full duplex transfer is done by shifting 4 bytes at a time, or even
one byte at a time for transfers less than 4 bytes long.
While this method is perfectly suitable for small transfers, it is still
slower than using the FIFOs.
This commit implement full-duplex support, making sure that half-duplex
transfers are still done using the FIFOs with the existing method.
Some setup functions were moved around to make sure the controller is
properly configured before beginning each transfer.
This was tested on EspressoBin with a logical analyser, and a simple
setup where MISO is connected on MOSI. Transfers were made from
userspace using spidev and spi-pipe from the spi-tools project

Armada 3700 SPI controller has an internal clock divider which can
divide the parent clock frequency by up to 30.
This patch sets the limits in the spi_controller fields so that we can
detect when a non-supported frequency is requested by a device for a
transfer.

When performing a read using FIFO mode, the spi controller shifts out
the last 2 bytes that were written in a previous transfer on MOSI.
This undocumented behaviour can cause devices to misinterpret the
transfer, so we explicitly clear the WFIFO before each read.
This behaviour was noticed on EspressoBin.

Some issues have been reported with the for loop in stop_this_cpu() that
issues the 'wbinvd; hlt' sequence. Reverting this sequence to halt()
has been shown to resolve the issue.
However, the wbinvd is needed when running with SME. The reason for the
wbinvd is to prevent cache flush races between encrypted and non-encrypted
entries that have the same physical address. This can occur when
kexec'ing from memory encryption active to inactive or vice-versa. The
important thing is to not have outside of kernel text memory references
(such as stack usage), so the usage of the native_*() functions is needed
since these expand as inline asm sequences. So instead of reverting the
change, rework the sequence.
Move the wbinvd instruction outside of the for loop as native_wbinvd()
and make its execution conditional on X86_FEATURE_SME. In the for loop,
change the asm 'wbinvd; hlt' sequence back to a halt sequence but use
the native_halt() call.

Keith reported an issue with vector space exhaustion on a server machine
which is caused by the i40e driver allocating 168 MSI interrupts when the
driver is initialized, even when most of these interrupts are not used at
all.
The x86 vector allocation code tries to avoid the immediate allocation with
the reservation mode, but the card uses MSI and does not support MSI entry
masking, which prevents reservation mode and requires immediate vector
allocation.
The matrix allocator is a bit naive and prefers the first CPU in the
cpumask which describes the possible target CPUs for an allocation. That
results in allocating all 168 vectors on CPU0 which later causes vector
space exhaustion when the NVMe driver tries to allocate managed interrupts
on each CPU for the per CPU queues.
Avoid this by finding the CPU which has the lowest vector allocation count
to spread out the non managed interrupt accross the possible target CPUs.

Current code configures the hardware with a new SA before the state has been
fully initialized. During this time interval, an incoming ESP packet can cause
a crash due to a NULL dereference. More specifically, xfrm_input() considers
the packet as valid, and yet, anti-replay mechanism is not initialized.
Move hardware configuration to the end of xfrm_state_construct(), and mark
the state as valid once the SA is fully initialized.

The E1 has two headphone jacks, one of which can be set as a microphone
input. In the default mode, it uses the built-in microphone as an input.
By sending a special command, the second headphone jack is instead used
as an input.
This might work with the E3 as well, but I don't have one of those to
test it.

If an invalid CANFD frame is received, from a driver or from a tun
interface, a Kernel warning is generated.
This patch replaces the WARN_ONCE by a simple pr_warn_once, so that a
kernel, bootet with panic_on_warn, does not panic. A printk seems to be
more appropriate here.

This IP provides the write protect signal level in the status
register, but it is also possible to use GPIO for WP. They are
exclusive, so it is not efficient to call mmc_gpio_get_ro() every
time from tmio_mmc_get_ro() if we know gpio_ro is not used.
Check the capability of gpio_ro just once in the probe function,
then set mmc_gpio_get_ro to .get_ro if it is the case.

mmc_of_parse() parses various DT properties and sets capability flags
accordingly. However, drivers have no chance to run platform init
code depending on such flags because mmc_of_parse() is called from
tmio_mmc_host_probe().
Move mmc_of_parse() to tmio_mmc_host_alloc() so that drivers can
handle capabilities before mmc_add_host(). Move tmio_mmc_of_parse()
likewise.

The clock is enabled in the tmio_mmc_host_probe(). It also prevents
drivers from performing platform-specific settings before mmc_add_host()
because the register access generally requires a clock.
Enable/disable the clock in drivers' probe/remove. Also, I passed
tmio_mmc_data to tmio_mmc_host_alloc() because renesas_sdhi_clk_enable()
needs it to get the private data from tmio_mmc_host.
