This patch adds SD/MMC support for STM32H7 SoCs.
Here is an extraction of SDMMC main features, embedded in
STM32H7 SoCs.
The SD/MMC block include the following:
_ Full compliance with MultiMediaCard System Specification
Version 4.51. Card support for three different databus modes:
1-bit (default), 4-bit and 8-bit.
_ Full compatibility with previous versions of MultiMediaCards
(backward compatibility).
_ Full compliance with SD memory card specifications version 4.1.
(SDR104 SDMMC_CK speed limited to maximum allowed IO speed,
SPI mode and UHS-II mode not supported).
_ Full compliance with SDIO card specification version 4.0.
Card support for two different databus modes: 1-bit (default)
and 4-bit. (SDR104 SDMMC_CK speed limited to maximum allowed IO
speed, SPI mode and UHS-II mode not supported).
_ Data transfer up to 208 Mbyte/s for the 8 bit mode.
(depending maximum allowed IO speed).
_ Data and command output enable signals to control external
bidirectional drivers.
The current version of the SDMMC supports only one SD/SDIO/MMC card
at any one time and a stack of MMC Version 4.51 or previous.

The Linux kernel driver sets the number of event segments and entries
to 1 , while the initial import of the xhci code set that values to 3
for reasons unknown. While most controllers are fine with more event
segments with more entries, there are standard-conformant controllers
(ie. Renesas RCar xHCI) which only support 1 event segment.
Set the number of event segments and event entries back to 1 to allow
such controllers to work with U-Boot xHCI stack. Note that the Renesas

- This adds support for reading the timer even before the

We want to support more than one phandle argument. It makes sense to use
an array for this rather than discrete struct members. Adjust the code to
support this. Rename the member to 'arg' instead of 'id'.

Rather than naming the phandle struct according to the number of cells it
uses (e.g. struct phandle_2_cell) name it according to the number of
arguments it has (e.g. struct phandle_1_arg). This is a more intuitive
naming.

When using 32-bit addresses dtoc works correctly. For 64-bit addresses it
does not since it ignores the #address-cells and #size-cells properties.
Update the tool to use fdt64_t as the element type for reg properties when
either the address or size is larger than one cell. Use the correct value
so that C code can obtain the information from the device tree easily.
Alos create a new type, fdt_val_t, which is defined to either fdt32_t or
fdt64_t depending on the word size of the machine. This type corresponds
to fdt_addr_t and fdt_size_t. Unfortunately we cannot just use those types
since they are defined to phys_addr_t and phys_size_t which use
'unsigned long' in the 32-bit case, rather than 'unsigned int'.
Add tests for the four combinations of address and size values (32/32,
64/64, 32/64, 64/32). Also update existing uses for rk3399 and rk3368
which now need to use the new fdt_val_t type.

By default, it is assumed that the UTMI clock is generated from
a 12 MHz reference clock (MAINCK). If it's not the case, the FREQ
field of the SFR_UTMICKTRIM has to be updated to generate the UTMI
clock in the proper way.
The UTMI clock has a fixed rate of 480 MHz. In fact, there is no
multiplier we can configure. The multiplier is managed internally,
depending on the reference clock frequency, to achieve the target
of 480 MHz.
The patch is cloned from the patch of mailing-list:

The STM32 LTDC display controller provides a parallel digital RGB and
signals for horizontal, vertical synchronization, Pixel Clock and Data
Enable as output to interface directly to a variety of LCD and TFT panels.
The LTDC main features are:
- 24-bit RGB Parallel Pixel Output, Programmable timings & polarity for
HSync, VSync and Data Enable.
- 2 layers with Blending, Color Keying, Window position & size,
Dithering, Background color, Color Look-Up Table (CLUT).
- Supported layer color formats: ARGB8888, RGB888, RGB565, ARGB1555,
ARGB4444, L8 CLUT, AL44 & AL88
This LTDC driver:
- supports: RGB parallel output with timings & polarity, 1 layer
in RGB565.
- supports but with hard-coded configurations: blending, window
position & size (crop), background color.
- does not support yet: rgb888, argb8888, 8-bit clut, dithering.
This LTDC driver is compatible with all stm32 platforms with the
