c4dedaaeb3 mmc: sdhci-pci-gli: GL9767: Fix low power mode in the SD Express process
When starting the SD Express process, the low power negotiation mode will
be disabled, so we need to re-enable it after switching back to SD mode.

8c68b5656e mmc: sdhci-pci-gli: GL9767: Fix low power mode on the set clock function
On sdhci_gl9767_set_clock(), the vendor header space(VHS) is read-only
after calling gl9767_disable_ssc_pll() and gl9767_set_ssc_pll_205mhz().
So the low power negotiation mode cannot be enabled again.
Introduce gl9767_set_low_power_negotiation() function to fix it.

The explanation process is as below.

static void sdhci_gl9767_set_clock()
{
	...
        gl9767_vhs_write();
        ...
	value |= PCIE_GLI_9767_CFG_LOW_PWR_OFF;
        pci_write_config_dword(pdev, PCIE_GLI_9767_CFG, value); <--- (a)

        gl9767_disable_ssc_pll(); <--- (b)
        sdhci_writew(host, 0, SDHCI_CLOCK_CONTROL);

        if (clock == 0)
                return;  <-- (I)

	...
        if (clock == 200000000 && ios->timing == MMC_TIMING_UHS_SDR104) {
		...
                gl9767_set_ssc_pll_205mhz(); <--- (c)
        }
	...
	value &= ~PCIE_GLI_9767_CFG_LOW_PWR_OFF;
        pci_write_config_dword(pdev, PCIE_GLI_9767_CFG, value); <-- (II)
        gl9767_vhs_read();
}

(a) disable low power negotiation mode. When return on (I), the low power
mode is disabled.  After (b) and (c), VHS is read-only, the low power mode
cannot be enabled on (II).

27e8fe0da3 mmc: sdhci-of-dwcmshc: Prevent stale command interrupt handling
While working with the T-Head 1520 LicheePi4A SoC, certain conditions
arose that allowed me to reproduce a race issue in the sdhci code.

To reproduce the bug, you need to enable the sdio1 controller in the
device tree file
`arch/riscv/boot/dts/thead/th1520-lichee-module-4a.dtsi` as follows:

&sdio1 {
	bus-width = <4>;
	max-frequency = <100000000>;
	no-sd;
	no-mmc;
	broken-cd;
	cap-sd-highspeed;
	post-power-on-delay-ms = <50>;
	status = "okay";
	wakeup-source;
	keep-power-in-suspend;
};

When resetting the SoC using the reset button, the following messages
appear in the dmesg log:

Here's what happens: the __mmc_start_request function is called with
opcode 5. Since the power to the Wi-Fi card, which resides on this SDIO
bus, is initially off after the reset, an interrupt SDHCI_INT_TIMEOUT is
triggered. Immediately after that, a second interrupt SDHCI_INT_RESPONSE
is triggered. Depending on the exact timing, these conditions can
trigger the following race problem:

1) The sdhci_cmd_irq top half handles the command as an error. It sets
   host->cmd to NULL and host->pending_reset to true.
2) The sdhci_thread_irq bottom half is scheduled next and executes faster
   than the second interrupt handler for SDHCI_INT_RESPONSE. It clears
   host->pending_reset before the SDHCI_INT_RESPONSE handler runs.
3) The pending interrupt SDHCI_INT_RESPONSE handler gets called, triggering
   a code path that prints: "mmc2: Got command interrupt 0x00000001 even
   though no command operation was in progress."

To solve this issue, we need to clear pending interrupts when resetting
host->pending_reset. This ensures that after sdhci_threaded_irq restores
interrupts, there are no pending stale interrupts.

The behavior observed here is non-compliant with the SDHCI standard.
Place the code in the sdhci-of-dwcmshc driver to account for a
hardware-specific quirk instead of the core SDHCI code.

c26339faed mmc: core: Only set maximum DMA segment size if DMA is supported
Since upstream commit 334304ac2b ("dma-mapping: don't return errors
from dma_set_max_seg_size") calling dma_set_max_seg_size() on a device
not supporting DMA results in a warning traceback. This is seen when
booting the sifive_u machine from SD. The underlying SPI controller
(sifive,spi0 compatible) explicitly sets dma_mask to NULL.

Avoid the backtrace by only calling dma_set_max_seg_size() if DMA is
supported.

cb787f4ac0 [tree-wide] finally take no_llseek out
no_llseek had been defined to NULL two years ago, in commit 868941b144
("fs: remove no_llseek")

To quote that commit,

  At -rc1 we'll need do a mechanical removal of no_llseek -

  git grep -l -w no_llseek | grep -v porting.rst | while read i; do
	sed -i '/\<no_llseek\>/d' $i
  done

  would do it.

Unfortunately, that hadn't been done.  Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
	.llseek = no_llseek,
so it's obviously safe.

6f25e5deca mmc: core: Convert simple_stroul to kstroul
simple_strtoul() is obsolete and lacks proper error handling, making it
unsafe for converting strings to unsigned long values. Replace it with
kstrtoul(), which provides robust error checking and better safety.

This change improves the reliability of the string-to-integer conversion
and aligns with current kernel coding standards. Error handling is added
to catch conversion failures, returning -EINVAL when input is invalid.

Issue reported by checkpatch:
- WARNING: simple_strtoul is obsolete, use kstrtoul instead

8396c793ff mmc: dw_mmc: Fix IDMAC operation with pages bigger than 4K
Commit 616f876617 ("mmc: pass queue_limits to blk_mq_alloc_disk") [1]
revealed the long living issue in dw_mmc.c driver, existing since the
time when it was first introduced in commit f95f3850f7 ("mmc: dw_mmc:
Add Synopsys DesignWare mmc host driver."), also making kernel boot
broken on platforms using dw_mmc driver with 16K or 64K pages enabled,
with this message in dmesg:

    mmcblk: probe of mmc0:0001 failed with error -22

That's happening because mmc_blk_probe() fails when it calls
blk_validate_limits() consequently, which returns the error due to
failed max_segment_size check in this code:

    /*
     * The maximum segment size has an odd historic 64k default that
     * drivers probably should override.  Just like the I/O size we
     * require drivers to at least handle a full page per segment.
     */
    ...
    if (WARN_ON_ONCE(lim->max_segment_size < PAGE_SIZE))
        return -EINVAL;

In case when IDMAC (Internal DMA Controller) is used, dw_mmc.c always
sets .max_seg_size to 4 KiB:

    mmc->max_seg_size = 0x1000;

The comment in the code above explains why it's incorrect. Arnd
suggested setting .max_seg_size to .max_req_size to fix it, which is
also what some other drivers are doing:

   $ grep -rl 'max_seg_size.*=.*max_req_size' drivers/mmc/host/ | \
     wc -l
   18

This change is not only fixing the boot with 16K/64K pages, but also
leads to a better MMC performance. The linear write performance was
tested on E850-96 board (eMMC only), before commit [1] (where it's
possible to boot with 16K/64K pages without this fix, to be able to do
a comparison). It was tested with this command:

    # dd if=/dev/zero of=somefile bs=1M count=500 oflag=sync

Test results are as follows:

  - 4K pages,  .max_seg_size = 4 KiB:                   94.2 MB/s
  - 4K pages,  .max_seg_size = .max_req_size = 512 KiB: 96.9 MB/s
  - 16K pages, .max_seg_size = 4 KiB:                   126 MB/s
  - 16K pages, .max_seg_size = .max_req_size = 2 MiB:   128 MB/s
  - 64K pages, .max_seg_size = 4 KiB:                   138 MB/s
  - 64K pages, .max_seg_size = .max_req_size = 8 MiB:   138 MB/s

Unfortunately, SD card controller is not enabled in E850-96 yet, so it
wasn't possible for me to run the test on some cheap SD cards to check
this patch's impact on those. But it's possible that this change might
also reduce the writes count, thus improving SD/eMMC longevity.

All credit for the analysis and the suggested solution goes to Arnd.

469e5e4713 mmc: core: apply SD quirks earlier during probe
Applying MMC_QUIRK_BROKEN_SD_CACHE is broken, as the card's SD quirks are
referenced in sd_parse_ext_reg_perf() prior to the quirks being initialized

To fix this problem, let's split out an SD-specific list of quirks and
apply in mmc_sd_init_card() instead. In this way, sd_read_ext_regs() to has
the available information for not assigning the SD_EXT_PERF_CACHE as one of
the (un)supported features, which in turn allows mmc_sd_init_card() to
properly skip execution of sd_enable_cache().

The SD/MMC block on the RZ/V2H(P) ("R9A09G057") SoC is similar to that
of the R-Car Gen3, but it has some differences:
- HS400 is not supported.
- It has additional SD_STATUS register to control voltage,
  power enable and reset.
- It supports fixed address mode.

To accommodate these differences, a SoC-specific 'renesas,sdhi-r9a09g057'
compatible string is added.

Note for RZ/V2H(P), we are using the `of_rzg2l_compatible` OF data as it
already handles no HS400 and fixed address mode support. Since the SDxIOVS
and SDxPWEN pins can always be used as GPIO pins on the RZ/V2H(P) SoC, no
driver changes are done to control the SD_STATUS register.

a1e627af32 mmc: mmc_test: Fix NULL dereference on allocation failure
If the "test->highmem = alloc_pages()" allocation fails then calling
__free_pages(test->highmem) will result in a NULL dereference.  Also
change the error code to -ENOMEM instead of returning success.

When we use cmd8 as the tuning command in hs400 mode, the command

c2a96b7f18 Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
 
 Lots of stuff in here, with not a huge diffstat, but apis are evolving
 which required lots of files to be touched.  Highlights of the changes
 in here are:
   - platform remove callback api final fixups (Uwe took many releases to
     get here, finally!)
   - Rust bindings for basic firmware apis and initial driver-core
     interactions.  It's not all that useful for a "write a whole driver
     in rust" type of thing, but the firmware bindings do help out the
     phy rust drivers, and the driver core bindings give a solid base on
     which others can start their work.  There is still a long way to go
     here before we have a multitude of rust drivers being added, but
     it's a great first step.
   - driver core const api changes.  This reached across all bus types,
     and there are some fix-ups for some not-common bus types that
     linux-next and 0-day testing shook out.  This work is being done to
     help make the rust bindings more safe, as well as the C code, moving
     toward the end-goal of allowing us to put driver structures into
     read-only memory.  We aren't there yet, but are getting closer.
   - minor devres cleanups and fixes found by code inspection
   - arch_topology minor changes
   - other minor driver core cleanups
 
 All of these have been in linux-next for a very long time with no
 reported problems.

63e555d9bf mmc: sdhci-esdhc-imx: obtain the 'per' clock rate after its enablement
The I.MX SDHCI driver assumes that the frequency of the 'per' clock
can be obtained even on disabled clocks, which is not always the case.

According to 'clk_get_rate' documentation, it is only valid
once the clock source has been enabled.
