Ulf Hansson fa700d7349 mmc: Revert "mmc: core: Allow mmc_start_host() synchronously detect a card"
It has turned out that some mmc host drivers were not ready to deal with
this change. Let's fix those host drivers first, then we can give this a
new try.

Pull gpio updates from Bartosz Golaszewski:
 "We have two new drivers, some improvements to the core code, lots of
  different updates to existing GPIO drivers and some dt-bindings on
  top.

  There's nothing controversial in here and almost everything has been
  in next for more than a week (95% a lot longer than this). The only
  thing that has spent less time in next is a new driver so no risk of
  regressions.

Ulf Hansson b1a665932d mmc: mmci: Add support for SW busy-end timeouts
The ux500 variant doesn't have a HW based timeout to use for busy-end IRQs.
To avoid hanging and waiting for the card to stop signaling busy, let's
schedule a delayed work, according to the corresponding cmd->busy_timeout
for the command. If the work gets to run, let's kick the IRQ handler to
complete the currently running request/command.

Marek Vasut c467c8f081 mmc: Add MMC_QUIRK_BROKEN_SD_CACHE for Kingston Canvas Go Plus from 11/2019
This microSD card never clears Flush Cache bit after cache flush has
been started in sd_flush_cache(). This leads e.g. to failure to mount
file system. Add a quirk which disables the SD cache for this specific
card from specific manufacturing date of 11/2019, since on newer dated
cards from 05/2023 the cache flush works correctly.

Robert Marko f1738a1f81 mmc: core: disable TRIM on Kingston EMMC04G-M627
It seems that Kingston EMMC04G-M627 despite advertising TRIM support does
not work when the core is trying to use REQ_OP_WRITE_ZEROES.

We are seeing I/O errors in OpenWrt under 6.1 on Zyxel NBG7815 that we did
not previously have and tracked it down to REQ_OP_WRITE_ZEROES.

Trying to use fstrim seems to also throw errors like:
[93010.835112] I/O error, dev loop0, sector 16902 op 0x3:(DISCARD) flags 0x800 phys_seg 1 prio class 2

Disabling TRIM makes the error go away, so lets add a quirk for this eMMC
to disable TRIM.

In stm32 sdmmc variant revision v3.0, a block gap hardware flow control
should be used with bus speed modes SDR104 and HS200.
It is enabled by writing a non-null value to the new added register
MMCI_STM32_FIFOTHRR.
The threshold will be 2^(N-1) bytes, so we can use the ffs() function to
compute the value N to be written to the register. The threshold used
should be the data block size, but must not be bigger than the FIFO size.

This makes the ux500 ->busy_complete() callback re-read
the status register 10 times while waiting for the busy
signal to assert in the status register.

If this does not happen, we bail out regarding the
command completed already, i.e. before we managed to
start to check the busy status.

There is a comment in the code about this, let's just
implement it to be certain that we can catch this glitch

Linus Walleij 7be5ac5f7a mmc: mmci: Make busy complete state machine explicit
This refactors the ->busy_complete() callback currently
only used by Ux500 and STM32 to handle busy detection on
hardware where one and the same IRQ is fired whether we get
a start or an end signal on busy detect.

The code is currently using the cached status from the
command IRQ in ->busy_status as a state to select what to
do next: if this state is non-zero we are waiting for
IRQs and if it is zero we treat the state as the starting
point for a busy detect wait cycle.

Make this explicit by creating a state machine where the
->busy_complete callback moves between three states.

The Ux500 busy detect code currently assumes this order:
we enable the busy detect IRQ, get a busy start IRQ, then a
busy end IRQ, and then we clear and mask this IRQ and
proceed.

We insert debug prints for unexpected states.

This works as before on most cards, however on a
problematic card that is not working with busy detect, and
which I have been debugging, the following happens a lot:

[    3.380554] mmci-pl18x 80005000.mmc: no busy signalling in time
[    3.387420] mmci-pl18x 80005000.mmc: no busy signalling in time
[    3.394561] mmci-pl18x 80005000.mmc: lost busy status
     when waiting for busy start IRQ

This probably means that the busy detect start IRQ has
already occurred when we start executing the
->busy_complete() callbacks, and the busy detect end IRQ
is counted as the start IRQ, and this is what is causing
the card to not be detected properly.

Linus Walleij e1a2485cc3 mmc: mmci: Break out error check in busy detect
The busy detect callback for Ux500 checks for an error
in the status in the first if() clause. The only practical
reason is that if an error occurs, the if()-clause is not
executed, and the code falls through to the last
if()-clause if (host->busy_status) which will clear and
disable the irq. Make this explicit instead: it is easier
to read.

if-expression:

With the more readable:

  if (!host->busy_status && !(status & err_msk)) {
     status = readl(base + MMCISTATUS);
     if (status & host->variant->busy_detect_flag) {

Second notice that the re-read MMCISTATUS register is now

if something else changed too?

Christophe Kerello 47b3ad6b78 mmc: mmci: stm32: fix max busy timeout calculation
The way that the timeout is currently calculated could lead to a u64
timeout value in mmci_start_command(). This value is then cast in a u32
register that leads to mmc erase failed issue with some SD cards.

Fixes: 8266c585f4 ("mmc: mmci: add hardware busy timeout feature")

Dennis Zhou 2cc83bf7d4 mmc: core: Allow mmc_start_host() synchronously detect a card
When using dm-verity with a data partition on an emmc device, dm-verity
races with the initialization of the (e)MMC/SD cards. This is because the
card detection procedure is being managed from a workqueue, rather than
synchronously from the mmc host's ->probe() routine.

To allow the card detect to be synchronous, let's simply skip using the
workqueue at the first initialization attempt from mmc_start_host().

Stephan Gerhold e6f9e590b7 mmc: sdhci-msm: Disable broken 64-bit DMA on MSM8916
While SDHCI claims to support 64-bit DMA on MSM8916 it does not seem to
be properly functional. It is not immediately obvious because SDHCI is
usually used with IOMMU bypassed on this SoC, and all physical memory
has 32-bit addresses. But when trying to enable the IOMMU it quickly
fails with an error such as the following:

Looking closely it's obvious that only the 32-bit part of the address
(0xfffff200) arrives at the SMMU, the higher 16-bit (0xffff...) get
lost somewhere. This might not be a limitation of the SDHCI itself but
perhaps the bus/interconnect it is connected to, or even the connection
to the SMMU.

Work around this by setting SDHCI_QUIRK2_BROKEN_64_BIT_DMA to avoid
using 64-bit addresses.

other uses of fmode_t are FMODE_READ and FMODE_WRITE.  Define a new
blk_mode_t instead for use in blkdev_get_by_{dev,path}, ->open and
->ioctl and stop abusing fmode_t.

Abel Vesa c7eed31e23 mmc: sdhci-msm: Switch to the new ICE API
Now that there is a new dedicated ICE driver, drop the sdhci-msm ICE
implementation and use the new ICE api provided by the Qualcomm soc
driver ice. The platforms that already have ICE support will use the
API as library since there will not be a devicetree node, but instead
they have reg range. In this case, the of_qcom_ice_get will return an
ICE instance created for the consumer's device. But if there are
platforms that do not have ice reg in the consumer devicetree node
and instead provide a dedicated ICE devicetree node, theof_qcom_ice_get
will look up the device based on qcom,ice property and will get the ICE
instance registered by the probe function of the ice driver.

The ICE clock is now handle by the new driver. This is done by enabling
it on the creation of the ICE instance and then enabling/disabling it on
SDCC runtime resume/suspend.

Victor Shih 0e92aec2ef mmc: sdhci-pci-gli: Add support SD Express card for GL9767
Add support SD Express card for GL9767. The workflow of the
SD Express card in GL9767 is as below.
1. GL9767 operates in SD mode and set MMC_CAP2_SD_EXP flag.
2. If card is inserted, Host send CMD8 to ask the capabilities
   of the card.
3. If the card has PCIe capability, then init_sd_express()
   will be invoked.
4. If the card has been put in write protect state then the
   SD features supported by SD mode but not supported by
   PCIe mode, therefore GL9767 switch to SD mode.
5. If the card has not been put in write protect state then
   GL9767 switch from SD mode to PCIe/NVMe mode and mmc driver
   handover control to NVMe driver.
6. If card is removed, GL9767 will return to SD mode.
