Pull MMC updates from Ulf Hansson:
"These are the updates for MMC and MEMSTICK for v5.5.

Note that this also contains quite some additional changes reaching
beyond both the MMC and MEMSTICK subsystems. This is primarily because
of fixing an old regression for a WiFi driver based on the SDIO
interface on an OMAP openpandora board

MMC core:
- Add CMD13 polling for MMC IOCTLS with R1B response.
- Add common DT properties for clk-phase-delays for various speed
modes.
- Fix size overflow for mmc gp-partitions.
- Re-work HW reset for SDIO cards, which also includes a re-work for
Marvell's WiFi mwifiex SDIO func driver.

MMC host:
- jz4740: Add support for X1000 and JZ4760.
- jz4740: Add support for 8-bit bus and for low power mode.
- mmci: Add support for HW busy timeout for the stm32_sdmmc variant.
- owl-mmc: Add driver for Actions Semi Owl SoCs SD/MMC controller.
- renesas_sdhi: Add support for r8a774b1.
- sdhci_am654: Add support for Command Queuing Engine for J721E.
- sdhci-milbeaut: Add driver for the Milbeaut SD controller.
- sdhci-of-arasan: Add support for ZynqMP tap-delays.
- sdhci-of-arasan: Add support for clk-phase-delays for SD cards.
- sdhci-of-arasan: Add support for Intel LGM SDXC.
- sdhci-of-aspeed: Allow inversion of the internal card detect
signal.
- sdhci-of-esdhc: Fixup workaround for erratum A-008171 for tunings.
- sdhci-of-at91: Improve support for calibration.
- sdhci-pci: Add support for Intel JSL.
- sdhci-pci: Add quirk for AMD SDHC Device 0x7906.
- tmio: Enable support for erase/discard/trim requests.

MMC/OMAP/pandora/wl1251:

The TI wl1251 WiFi driver for SDIO on the OMAP openpandora board has
been broken since v4.7. To fix the problems, changes have been made
cross subsystems, but also to OMAP2 machine code and to openpandora
DTS files, as summarized below. Relevant changes have been tagged for
stable.

- mmc/wl1251: Re-introduce lost SDIO quirks and vendor-id for wl1251
- omap/omap_hsmmc: Remove redundant platform config for openpandora
- omap_hsmmc: Initialize non-std SDIO card for wl1251 for pandora
- omap/dts/pandora: Specify wl1251 through a child node of mmc3
- wl1251: Add devicetree support for TI wl1251 SDIO"

mmc: sdhci-of-esdhc: fix up erratum A-008171 workaround

A previous patch implemented an incomplete workaround of erratum
A-008171. The complete workaround is as below. This patch is to
implement the complete workaround which uses SW tuning if HW tuning
fails, and retries both HW/SW tuning once with reduced clock if
workaround fails. This is suggested by hardware team, and the patch
had been verified on LS1046A eSDHC + Phison 32G eMMC which could
trigger the erratum.

Workaround:
/* For T1040, T2080, LS1021A, T1023 Rev 1: */
1. Program TBPTR[TB_WNDW_END_PTR] = 3*DIV_RATIO.
2. Program TBPTR[TB_WNDW_START_PTR] = 5*DIV_RATIO.
3. Program the software tuning mode by setting TBCTL[TB_MODE] = 2'h3.
4. Set SYSCTL2[EXTN] and SYSCTL2[SAMPCLKSEL].
5. Issue SEND_TUNING_BLK Command (CMD19 for SD, CMD21 for MMC).
6. Wait for IRQSTAT[BRR], buffer read ready, to be set.
7. Clear IRQSTAT[BRR].
8. Check SYSCTL2[EXTN] to be cleared.
9. Check SYSCTL2[SAMPCLKSEL], Sampling Clock Select. It's set value
indicate tuning procedure success, and clear indicate failure.
In case of tuning failure, fixed sampling scheme could be used by
clearing TBCTL[TB_EN].
/* For LS1080A Rev 1, LS2088A Rev 1.0, LA1575A Rev 1.0: */
1. Read the TBCTL[31:0] register. Write TBCTL[11:8]=4'h8 and wait for
1ms.
2. Read the TBCTL[31:0] register and rewrite again. Wait for 1ms second.
3. Read the TBSTAT[31:0] register twice.
3.1 Reset data lines by setting ESDHCCTL[RSTD] bit.
3.2 Check ESDHCCTL[RSTD] bit.
3.3 If ESDHCCTL[RSTD] is 0, go to step 3.4 else go to step 3.2.
3.4 Write 32'hFFFF_FFFF to IRQSTAT register.
4. if TBSTAT[15:8]-TBSTAT[7:0] > 4*DIV_RATIO or TBSTAT[7:0]-TBSTAT[15:8]
> 4*DIV_RATIO , then program TBPTR[TB_WNDW_END_PTR] = 4*DIV_RATIO and
program TBPTR[TB_WNDW_START_PTR] = 8*DIV_RATIO.
/* For LS1012A Rev1, LS1043A Rev 1.x, LS1046A 1.0: */
1. Read the TBCTL[0:31] register. Write TBCTL[20:23]=4'h8 and wait for
1ms.
2. Read the TBCTL[0:31] register and rewrite again. Wait for 1ms second.
3. Read the TBSTAT[0:31] register twice.
3.1 Reset data lines by setting ESDHCCTL[RSTD] bit.
3.2 Check ESDHCCTL[RSTD] bit.
3.3 If ESDHCCTL[RSTD] is 0, go to step 3.4 else go to step 3.2.
3.4 Write 32'hFFFF_FFFF to IRQSTAT register.
4. if TBSTAT[16:23]-TBSTAT[24:31] > 4*DIV_RATIO or TBSTAT[24:31]-
TBSTAT[16:23] > 4* DIV_RATIO , then program TBPTR[TB_WNDW_END_PTR] =
4*DIV_RATIO and program TBPTR[TB_WNDW_START_PTR] = 8*DIV_RATIO.
/* For LS1080A Rev 1, LS2088A Rev 1.0, LA1575A Rev 1.0 LS1012A Rev1,
* LS1043A Rev 1.x, LS1046A 1.0:
*/
5. else program TBPTR[TB_WNDW_END_PTR] = 3*DIV_RATIO and program
TBPTR[TB_WNDW_START_PTR] = 5*DIV_RATIO.
6. Program the software tuning mode by setting TBCTL[TB_MODE] = 2'h3.
7. Set SYSCTL2[EXTN], wait 1us and SYSCTL2[SAMPCLKSEL].
8. Issue SEND_TUNING_BLK Command (CMD19 for SD, CMD21 for MMC).
