f7c48bccf1 mtd: rawnand: print offset instead of page number for bad blocks
This makes printed info consistent with other kernel messages. After
scanning NAND BBT create_bbt() prints offset of each bad block. This
change makes is easy to verify nand_erase_nand() failure reason.

fecbd4a317 mtd: rawnand: atmel: fix refcount issue in atmel_nand_controller_init
The reference counting issue happens in several error handling paths
on a refcounted object "nc->dmac". In these paths, the function simply
returns the error code, forgetting to balance the reference count of
"nc->dmac", increased earlier by dma_request_channel(), which may
cause refcount leaks.

Fix it by decrementing the refcount of specific object in those error
paths.

42da5a4ba1 mtd: rawnand: omap2: Actually prevent invalid configuration and build error
The root of the problem is that we are selecting symbols that have
dependencies. This can cause random configurations that can fail.
The cleanest solution is to avoid using select.

This driver uses interfaces from the OMAP_GPMC driver so we have to
depend on it instead.

ad5e35f583 mtd: Replace the expert mode symbols with a single helper
Reduce the number of exported symbols by replacing:
- mtd_expert_analysis_warning (the error string)
- mtd_expert_analysis_mode (the boolean)
with a single helper:
- mtd_check_expert_analysis_mode

Calling this helper will both check/return the content of the internal
boolean -which is not exported anymore- and as well conditionally
WARN_ONCE() the user, like it was done before.

While on this function, make the error string local to the helper and
set it const. Only export this helper when CONFIG_DEBUG_FS is defined to
limit the growth of the Linux kernel size only for a debug feature on
production kernels.

Mechanically update all the consumers.

3f26d1bf90 mtd: Fix misuses of of_match_ptr()
of_match_ptr() either expands to NULL if !CONFIG_OF, or is transparent
otherwise. There are several drivers using this macro which keep their
of_device_id array enclosed within an #ifdef CONFIG_OF check, these are
considered fine. However, When misused, the of_device_id array pointed
by this macro will produce a warning because it is finally unused when
compiled without OF support.

A number of fixes are possible:
- Always depend on CONFIG_OF, but this will not always work and may
  break boards.
- Enclose the compatible array by #ifdef's, this may save a bit of
  memory but will reduce build coverage.
- Tell the compiler the array may be unused, if this can be avoided,
  let's not do this.
- Just drop the macro, setting the of_device_id array for a non OF
  enabled platform is not an issue, it will just be unused.

The latter solution seems the more appropriate, so let's use it.

The brcmnand driver contains a bug in which if a page (example 2k byte)
is read from the parallel/ONFI NAND and within that page a subpage (512
byte) has correctable errors which is followed by a subpage with
uncorrectable errors, the page read will return the wrong status of
correctable (as opposed to the actual status of uncorrectable.)

The bug is in function brcmnand_read_by_pio where there is a check for
uncorrectable bits which will be preempted if a previous status for
correctable bits is detected.

The fix is to stop checking for bad bits only if we already have a bad
bits status.

Interacting with a NAND chip on an IPQ6018 I found that the qcomsmem NAND
partition parser was returning -EPROBE_DEFER waiting for the main smem
driver to load.

This caused the board to reset. Playing about with the probe() function
shows that the problem lies in the core clock being switched off before the
nandc_unalloc() routine has completed.

If we look at how qcom_nandc_remove() tears down allocated resources we see
the expected order is

qcom_nandc_unalloc(nandc);

clk_disable_unprepare(nandc->aon_clk);
clk_disable_unprepare(nandc->core_clk);

dma_unmap_resource(&pdev->dev, nandc->base_dma, resource_size(res),
		   DMA_BIDIRECTIONAL, 0);

Tweaking probe() to both bring up and tear-down in that order removes the
reset if we end up deferring elsewhere.

15e27d197a mtd: rawnand: gpmi: validate controller clock rate
What to do when the real rate of the gpmi clock is not equal to the
required one? The solutions proposed in [1] did not lead to a conclusion
on how to validate the clock rate, so, inspired by the document [2], I
consider the rate correct only if not lower or equal to the rate of the
previous edo mode. In fact, in chapter 4.16.2 (NV-DDR) of the document [2],
it is written that "If the host selects timing mode n, then its clock
period shall be faster than the clock period of timing mode n-1 and
slower than or equal to the clock period of timing mode n.". I thought
that it could therefore also be used in this case, without therefore
having to define the valid rate ranges empirically.

For example, suppose that gpmi_nfc_compute_timings() is called to set
edo mode 5 (100MHz) but the rate returned by clk_round_rate() is 80MHz
(edo mode 4). In this case gpmi_nfc_compute_timings() will return error,
and will be called again to set edo mode 4, which this time will be
successful.

109cf81fb5 mtd: rawnand: nandsim: Add NS_PAGE_BYTE_SHIFT macro to replace the repeat pattern
The (ns->regs.column + ns->regs.off) pattern repeats a lot which
represents the byte shift in next page to access. We can replace it

3ceff4ea07 sound updates for 5.17-rc1
It's a relatively calm development cycle, but still lots of updates in
 the driver side like Intel SOF.  Below are some highlights:
 
 * ALSA / ASoC core:
 - A new kselftest for ALSA control API
 - PCM NO_REWINDS support
 - Potential race fixes around control removals
 - Unify x86 SG-buffer memory allocation code
 - Cleanups and race fixes for ASoC DPCM locking
 
 * ASoC:
 - Refinements and cleanups around the delay() APIs
 - Wider use of dev_err_probe().
 - Continuing cleanups and improvements to the SOF code
 - Support for pin switches in simple-card derived cards
 - Support for AMD Renoir ACP, Asahi Kasei Microdevices AKM4375, Intel
   systems using NAU8825 and MAX98390, Mediatek MT8915, nVidia Tegra20
   S/PDIF, Qualcomm systems using ALC5682I-VS and Texas Instruments
   TLV320ADC3xxx
 
 * HD-audio / USB-audio:
 - Fix deadlock at HD-audio codec unbinding
 - Fixes for Tegra194 HD-audio, new HDA support for CS35L41 codec
 - Quirks for Lenovo and HP machines, Gigabyte mobo, Bose device
 
 * Misc:
 - Fix virmidi drain behavior
 
 Note that the merge of CS35L41 codec support is still half-baked, and
 at least one ACPI change is missing.  Although this won't hinder the
 kernel build itself, we're going to catch up before RC1.

 Noteworthy new features are:
 
  - The op-tee firmware driver gains support for asynchronous
    notifications from secure-world firmware.
 
  - Qualcomm platforms gain support for new SoC types in various
    drivers: power domain, cache controller, RPM sleep, soc-info
 
  - Samsung SoC drivers gain support for new SoCs in ChipID and PMU,
    as well as a new USIv2 driver that handles various types of
    serial communiction (uart, i2c, spi)
 
  - Renesas adds support for R-Car S4-8 (R8A779F0) in multiple
    drivers, as well as memory controller support for RZ/G2L
    (R9A07G044).

compatible and another moved the IDs to a header which created a
conflict: moving the new ID as well in the header fixed it.]

ecb78b290b mtd: rawnand: gpmi: Use platform_get_irq_byname() to get the interrupt
platform_get_resource_byname(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypasses the hierarchical setup and messes up the
irq chaining.

In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq_byname().
