The SD physical layer specification requires that the operating supply
be stable for at least 1 millisecond before providing the required 74
clocks. The maximum VDD ramp time is specified at 35ms, giving a total
minimum delay of 36ms.

This Kconfig has wrongly been added to defconfig files. It is not the

that need it should select the symbol in their Kconfig entries. Drop
PINCTL from Kconfig.defconfig and add proper select at Kconfig.sam*.

The imx USDHC driver previously queried the peripheral's internal card
detect signal to check card presence if no card detect method was
configured. However, some boards do not route the card detect signal and
do not work correctly with the DAT3 detection method supported by this
peripheral. As a fallback, assume the card is present in the slot but
log a warning to the user.

Rework CMD12 failure logic for SDHC SPI driver. Previously, the error
code of CMD12 was not checked, so even if CMD12 failed to send the
initial command would be retried. Change this behavior to retry CMD12
until it succeeds. If CMD12 fails, its error code will be propagated to
the caller. Otherwise, the return code from the command being sent by
the caller will be propagated.

Add basic functionality of Renesas SD/MMC driver. It can be used
for both gen3 and gen4 R-car boards, but tested only with H3ULCB,
Salvator XS M3 and Spider boards. This driver working with SDHC
subsystem.
The driver supports regularal reading/writing throught SD/MMC
controller buffer, DMA mode w/o interrupts and timing tuning.
Add gpio5 and sd0 nodes to h3ulcb and salvator xs which are needed
for working with SD cards. The GPIO node is needed for switching
voltage on SD card through gpio regulator driver.
Notes:
* the driver doesn't support SPI mode;
* SCC tuning and DMA mode based on IRQs are enabled by default;
* an address of a data buffer has to be aligned to 128 bytes if it
is not, driver will use non-DMA mode automatically;
* Renesas MMC DMAC doesn't support 64-bit DMA addresses, so for
case when we have 64-bit xref data address we use non-DMA mode;
* SD/MMC controller supports block size between 512 and 1 with
a lot of restrictions, more details you can find in code;
* support of HS400 mode isn't implemented inside driver.

This change marks each instance of the 'api' as 'static const'.
The rationale is that 'api' is used for declaring internal
module interfaces and is not intended to be modified at runtime.
By using 'static const', we ensure immutability, leading to usage of only
.rodata and a reduction in the .data area.

In sdhc_spi_response_get, the logic for slow cards previously only

Enable SPI SDHC driver to manage card power via pwr-gpios property.
Control for this property was previously partially implemented. When
this property is present, the SPI SDHC driver will use it to control
power to the SD card.
Power is toggled during SD init, so this power control can make SD init
more reliable as the power toggle will insure the SD card state is reset.
