In order to avoid having to touch memory with the MMU and caches
disabled, and therefore having to invalidate it from the caches
explicitly, just defer storing the value until after the MMU has been
turned on, unless we are giving up with an error.
While at it, move the associated variable definitions into C code.

Now that we can access the entire kernel image via the ID map, we can
execute the page table population code with the MMU and caches enabled.
The only thing we need to ensure is that translations via TTBR1 remain
disabled while we are updating the page tables the second time around,
in case KASLR wants them to be randomized.

Instead of calling into the kernel to map the FDT into the kernel page
tables before even calling start_kernel(), let's switch to the initial,
temporary mapping of the device tree that has been added to the ID map.

We need to access the DT very early to get at the command line and the
KASLR seed, which currently means we rely on some hacks to call into the
kernel before really calling into the kernel, which is undesirable.
So instead, let's create a mapping for the FDT in the initial ID map,
which is feasible now that it has been extended to cover more than a
single page or block, and can be updated in place to remap other output
addresses.

Formerly, we had to access the RELA and RELR tables via the kernel
mapping that was being relocated, and so deriving the start and end
addresses using ADRP/ADD references was not possible, as the relocation
code runs from the ID map.
Now that we map the entire kernel image via the ID map, we can simplify
this, and just load the entries via the ID map as well.

As a first step towards avoiding the need to create, tear down and
recreate the kernel virtual mapping with MMU and caches disabled, start
by expanding the ID map so it covers the page tables as well as all
executable code. This will allow us to populate the page tables with the
MMU and caches on, and call KASLR init code before setting up the
virtual mapping.
Since this ID map is only needed at boot, create it as a temporary set
of page tables, and populate the permanent ID map after enabling the MMU
and caches. While at it, switch to read-only attributes for the where
possible, as writable permissions are only needed for the initial kernel
page tables. Note that on 4k granule configurations, the permanent ID
map will now be reduced to a single page rather than a 2M block mapping.

The asm macros used to create the initial ID map and kernel mappings
don't support randomly remapping parts of the address space after it has
been populated. What we can do, however, given that all block or page
mappings are created at the final level, is take a subset of the mapped
range and update its attributes or output address. This will permit us
to make parts of these page tables read-only, or remap a part of it to
cover the device tree.
So add a helper that encapsulates this.

Some early boot code runs before the virtual placement of the kernel is
finalized, and we used to go back to the very start and recreate the ID
map along with the page tables describing the virtual kernel mapping,
and this involved setting some global variables with the caches off.
In order to ensure that global state created by the KASLR code is not
corrupted by the cache invalidation that occurs in that case, we needed
to clean those global variables to the PoC explicitly.
This is no longer needed now that the ID map is created only once (and
the associated global variable updates are no longer repeated). So drop
the cache maintenance that is no longer necessary.

Split off the creation of the ID map page tables, so that we can avoid
running it again unnecessarily when KASLR is in effect (which only
randomizes the virtual placement). This will permit us to drop some
explicit cache maintenance to the PoC which was necessary because the
cache invalidation being performed on some global variables might
otherwise clobber unrelated variables that happen to share a cacheline.

In a future patch, we will start using an ID map that covers the entire
image, rather than a single page. This means that we need to deal with
the pathological case of an extended ID map where the kernel image does
not fit neatly inside a single entry at the root level, which means we
will need to create additional table entries and map additional pages
for page tables.
The existing map_memory macro already takes care of most of that, so
let's just extend it to deal with this case as well. While at it, drop
the conditional branch on the value of T0SZ: we don't set the variable
anymore in the entry code, and so we can just let the map_memory macro
deal with the case where the output address exceeds VA_BITS.

Simplify the macros in head.S that are used to set up the early page
tables, by switching to immediates for the number of bits that are
interpreted as the table index at each level. This makes it much
easier to infer from the instruction stream what is going on, and
reduces the number of instructions emitted substantially.
Note that the extended ID map for cases where no additional level needs
to be configured now uses a compile time size as well, which means that
we interpret up to 10 bits as the table index at the root level (for
52-bit physical addressing), without taking into account whether or not
this is supported on the current system. However, those bits can only
be set if we are executing the image from an address that exceeds the
48-bit PA range, and are guaranteed to be cleared otherwise, and given
that we are dealing with a mapping in the lower TTBR0 range of the
address space, the result is therefore the same as if we'd mask off only
6 bits.

Setting idmap_t0sz involves fiddling with the caches if done with the
MMU off. Since we will be creating an initial ID map with the MMU and

it with a macro that simply issues the three instructions needed to
calculate the value wherever it is needed before the MMU is turned on.

There are some functions that were missed by commit d77e74561368 ("regmap:

bulk read/write callbacks in regmap_config was introduced.
The regmap_bulk_write() and regmap_noinc_write() functions weren't changed
to use the added map->write instead of the map->bus->write handler.
Also, the regmap_can_raw_write() was not modified to take map->write into
account. So will only return true if a bus with a .write callback is set.

by the commit d77e74561368 ("regmap: Add bulk read/write callbacks into

a map->bus->read callback wasn't set.
But that commit dropped the check and now a call to _regmap_raw_read() is
attempted even when bulk read operations are not supported. That function
checks for map->read anyways but there's no point to continue if the read
can't succeed.
Also is a fragile assumption to make so is better to make it fail earlier.

DAPM keeps a copy of the current value of mux/demux controls,
however this value is only initialised in the case of autodisable
controls. This leads to false notification events when first
modifying a DAPM kcontrol that has a non-zero default.
Autodisable controls are left as they are, since they already
initialise the value, and there would be more work required to
support autodisable muxes where the first option isn't disabled
and/or that isn't the default.
Technically this issue could affect mixer/switch elements as well,
although not on any of the devices I am currently running. There
is also a little more work to do to address the issue there due to
that side supporting stereo controls, so that has not been tackled
in this patch.

We discoverd that the state of BCLK on, LRCLK off and SD_MODE on
may cause the speaker melting issue. Removing LRCLK while BCLK
is present can cause unexpected output behavior including a large
DC output voltage as described in the Max98357a datasheet.
In order to:
1. prevent BCLK from turning on by other component.
2. keep BCLK and LRCLK being present at the same time
This patch switches BCLK to GPIO func before LRCLK output, and
configures BCLK func back during LRCLK is output.
Without this fix, BCLK is turned on 11 ms earlier than LRCK by the
da7219.
With this fix, BCLK is turned on only 0.4 ms earlier than LRCK by
the rockchip codec.

The IMR was assumed to be preserved when suspending to S4 and S5
states, but community reports invalidate that assumption, the hardware
seems to be powered off and the IMR memory content cleared.
Make sure regular boot with firmware download is used for S4 and S5.

We currently don't have a means to differentiate between S3, S4 and
S5. Add definitions so that we have select different code paths
depending on the target state in follow-up patches.

Commit 288fad2f71fa ("ASoC: SOF: Intel: hda: add quirks for HDAudio DMA position information")
modified the PCM path only, but left the compressed data patch using an
obsolete option.
Move the functionality in a helper that can be called for both PCM and
compressed data.

The "wlf,spkvdd-ena" GPIO needed by the bytcr_wm5102 driver
is made available through a gpio-lookup table.
This gpio-lookup table is registered by drivers/mfd/arizona-spi.c, which
may get probed after the bytcr_wm5102 driver.
If the gpio-lookup table has not registered yet then the gpiod_get()
will return -ENOENT. Treat -ENOENT as -EPROBE_DEFER to still keep
things working in this case.

Keyon Jie was a key contributor to the Intel ASoC and SOF Intel
drivers, but he's moved on to a different role within Intel. We wish
him all the best in his new endeavors.
Bard Liao, Kai Vehmanen, Ranjani Sridharan and Peter Ujfalusi have
been involved in the Intel multi-maintainer team, it's time to update
the MAINTAINERS entry to reflect their contributions and clarify their
role.

Currently wcd938x_*_put() unconditionally report that the value of the
control changed, resulting in spurious events being generated. Return 0 in
that case instead as we should. There is still an issue in the compander
control which is a bit more complex.
