99ae5e3234 video: sunxi: de2: switch to public uclass functions
Currently DE2 driver uses functions which are defined in internal
headers. They are not meant to be used outside of uclass framework.
Switch DE2 driver to public ones. This has additional benefit that
device_probe doesn't need to be called manually.

59dd8622d0 video: sunxi: dw-hdmi: read source_id later
There is no real need to read source_id at probe time. It also doesn't
make sense to store it in driver private data since it's already stored
in class platform data. While this looks like cleanup (and it is), it's
also important for DE2 driver rework because this info will be filled
later (after probe is already executed).

935b5198ef video: sunxi: Use DW-HDMI hpd function
It turns out that there are two ways how hot plug detection can be done.
One is standard way for DW HDMI controller - checking bit 2 in 0x3004
register. Another way is applicable only to Allwinner custom PHY - by
checking bit 19 in register 0x10038. Both methods are equally good as
far as we know.

Use standard method in order to reduce amount of custom code.

3daea8632c common: edid: extract code for detailed timing search
Code which searches for valid detailed timing entry will be used in more
places. Extract it.

No functional change is made. However, descriptors are casted to
edid_detailed_timing instead of edid_monitor_descriptor. Descriptor can
be of either type, but since we're interested only in DTD, it is more
fitting to cast to edid_detailed_timing.

e1769da17e usb: ehci-hcd: Add IAA handshake for removing async QH
According to EHCI spec, software needs to do handshake with HC for
safely removing QH from async list. This handshake is implemented by
setting IAAD (Interrupt on Async Advance Doorbell) bit in USB_USBCMD
register and poll the IAA (Interrupt on Async Advance bit) in the
USB_USBSTS to ensure the HC has released all on-chip state that may
potentially reference one of the data structures just removed.

Current codes only check active status of the last QTD, but this can't
ensure the QH is released from HC. We can meet unrecoverable
"EHCI timed out on TD" errors when running UEFI SCT tests on USB disk.
The USB_ASYNCLISTADDR register is changed to a invalid address when the
issue happens. It is fixed after adding the IAA handshake.

Steps to reproduce the issue:
1. Build the UEFI SCT from https://github.com/tianocore/edk2-test
2. Build the EDK2 UEFI Shell from https://github.com/tianocore/edk2
3. Copy SCT files and Shell.efi to USB disk FAT partition
4. Load the Shell.efi from USB FAT, and run bootefi to execute it
5. After booting into Shell, enter the SCT directory and run "sct -a"
   to execute all tests.
6. Tests run about 1 hour and stop with many EHCI timeout errors like
   EHCI timed out on TD - token=0x801f8c80

0089affee2 configs: stm32mp15: increase the number of reserved memory region in lmb
For the latest kernel device tree the max number of reserved regions
in lmb library is reached: 8 with 5 reserved regions in device tree.

When a new region is added, the lmb allocation for the device tree
relocation failed and boot with ramdisk failed.

This patch avoids this issue by increasing the max number of
supported reserved memory in lmb library to 16.

6d66502bc7 lmb: Add 2 config to define the max number of regions
Add 2 configs CONFIG_LMB_MEMORY_REGIONS and CONFIG_LMB_RESERVED_REGIONS
to change independently the max number of the regions in lmb
library.

When CONFIG_LMB_USE_MAX_REGIONS=y, move the lmb property arrays to
struct lmb and manage the array size with the element 'max' of struct
lmb_region; their are still allocated in stack.

When CONFIG_LMB_USE_MAX_REGIONS=n, keep the current location in
struct lmb_region to allow compiler optimization.

Increase CONFIG_LMB_RESERVED_REGIONS is useful to avoid lmb errors in
bootm when the number of reserved regions (not adjacent) is reached:
+ 1 region for relocated U-Boot
+ 1 region for initrd
+ 1 region for relocated linux device tree
+ reserved memory regions present in Linux device tree.

The current limit of 8 regions is reached with only 5 reserved regions
in DT.

b7135b034f psci: add features/reset2 support
Adds support for:
* PSCI_FEATURES, which was introduced in PSCI 1.0. This provides API
that allows discovering whether a specific PSCI function is implemented
and its features.
* SYSTEM_RESET2, which was introduced in PSCI 1.1, which extends existing
SYSTEM_RESET. It provides support for vendor-specific resets, providing
reset_type as an additional param.

For additional details visit [1].

Implementations of some functions were borrowed from Linux PSCI driver
code [2].
