8cb9d3ed3a mmc: dw_mmc: Fixes data read when receiving DTO interrupt in FIFO mode
The data read is not working when using FIFO mode.

From DesignWare databook, when a Data_Transfer_Over (DTO) interrupt is
received, the software should read the remaining data from FIFO.

Add DTO interrupt checking on data read path and clear interrupts before
start reading from FIFO. So, it doesn't clear the next pending
interrupts unintentionally after read from FIFO.

3a3672cc37 mmc: mtk-sd: increase the minimum bus frequency
With a 48MHz input clock, the lowest bus frequency can be as low as
48000000 / (4 * 4095) = 2930Hz. Such an extremely low frequency will cause
the mmc framework take seconds to finish the initialization.

Limiting the minimum bus frequency to a slightly higher value can solve the
issue without any side effects.

ae7020b435 mmc: fsl_esdhc: convert to CONFIG_FSL_ESDHC_VS33_NOT_SUPPORT
For eSDHC, power supply is through peripheral circuit.
Some eSDHC versions have value 0 of the bit but that
does not reflect the truth. 3.3V is common for SD/MMC,
and is supported for all boards with eSDHC in current
u-boot. So, make 3.3V is supported in default in code.
CONFIG_FSL_ESDHC_VS33_NOT_SUPPORT can be enabled if
future board does not support 3.3V.

This is also a fix-up for one previous patch, which converted
to use IS_ENABLED() for CONFIG_SYS_FSL_MMC_HAS_CAPBLT_VS33
that is not a Kconfig option.

8974ff1a60 mmc: fsl_esdhc_imx: add extra delay for IO voltage switch if necessary
Some board like imx8mm-evkb, IO voltage switch from 3.3v to 1.8v need
around 18ms, common code only delay 10ms, so need to delay extra 8ms.
Otherwise voltage switch will timeout when wait for data0 line.

This IO voltage switch time depends on board design, depend on the
PMIC and capacitance. imx8mm-evkb board use PCA9450(PMIC) and 10uF
capacitance.

For FSL_USDHC, it do not implement VENDORSPEC_CKEN/PEREN/HCKEN/IPGEN, these
are reserved bits. Instead, use VENDORSPEC_FRC_SDCLK_ON to gate on/off the
card clock output.

After commit b5874b552f ("mmc: fsl_esdhc_imx: add wait_dat0() support"),
we meet SD3.0 card can't work at UHS mode, mmc_switch_voltage() fail because
the second mmc_wait_dat0 return -ETIMEDOUT. According to SD spec, during
voltage switch, need to gate off/on the card clock. If not set the FRC_SDCLK_ON,
after CMD11, hardware will gate off the card clock automatically, so card do
not detect the clock off/on behavior, so will draw the data0 line low until
next command.

of-platdata-inst we do not use driver_info, but instead instantiate
udevice records at build-time.

However the semantics of using the function are the same in each case:
the caller provides an index and gets back a device.

So rename the function to device_get_by_ofplat_idx(), so that it can be
used for both situations. The caller does not really need to worry about

9b7aac7536 clk: zynq: Add dummy clock enable function
A lot of Xilinx drivers are checking -ENOSYS which means that clock driver
doesn't have enable function. Remove this checking from drivers and create
dummy enable function as was done for clk_fixed_rate driver by
commit 6bf6d81c11 ("clk: fixed_rate: add dummy enable() function").

2f22cb40e5 mmc: mmc_spi: Fix potential spec violation in receiving card response
After command is sent and before card response shows up on the line,
there is a variable number of clock cycles in between called Ncr.
The spec [1] says the minimum is 1 byte and the maximum is 8 bytes.

Current logic in mmc_spi_sendcmd() has a flaw that it could only work
with certain SD cards with their Ncr being just 1 byte.

When resp_match is false, the codes try to receive only 1 byte from
the SD card. On the other hand when resp_match is true, the logic
happens to be no problem as it loops until timeout to receive as many
bytes as possible to see a match of the expected resp_match_value.
However not every call to mmc_spi_sendcmd() is made with resp_match
being true hence this exposes a potential issue with SD cards that
have a larger Ncr value.

Given no issue was reported as of today, we can reasonably conclude
that all cards being used on the supported boards happen to have a 1
byte Ncr timing requirement. But a broken case can be triggered by
utilizing QEMU to emulate a larger value of Ncr (by default 1 byte
Ncr is used on QEMU). This commit fixes such potential spec violation
to improve the card compatibility.

37e1362efc mmc: sdhci: skip cache invalidation if DMA is not used
If DMA(SDMA or ADMA) is not used, the cache invalidation
after reading is no need, should be skipped. Otherwise
U-Boot may hang at the cache invalidation.

Found this issue and tested this fix on DragonBoard 410c.
