The leap year check in rtc_set() passes the loop variable 'i' (month
index, always 1 when the condition is true) to isleap() instead of the
actual year. Since isleap(1) is always false, February 29th is never
accounted for when computing the day count, resulting in the RTC being
set one day behind for any date after February in a leap year.
Pass tmp->tm_year to isleap() so the leap day is correctly included.

Add a SDRAM controller driver for the AST2700, derived from the
existing AST2700 controller code used by the Ibex SPL but adapted
to run from ARM U-Boot proper on the Cortex-A35 cores.
The DDR4/DDR5 controller and its DesignWare PHY are programmed by
the Ibex SPL before ARM U-Boot proper takes over. This driver
reads back the configuration left by the SPL, probes the
controller, and exposes ram_info (base and size, with the VGA
carve-out subtracted) via UCLASS_RAM so that dram_init() can
populate gd->ram_size.
The PHY firmware-load entry points (dwc_ddrphy_phyinit_userCustom_*)
are kept compiled but call a __weak fmc_hdr_get_prebuilt() stub
when ARM U-Boot proper is the caller; the real implementation is
provided by the Ibex SPL via the same fmc_hdr.h descriptor format
(here added for the ARM build).
Adds the supporting register-layout headers under
arch/arm/include/asm/arch-aspeed/:
- sdram.h: SDRAM controller and DWC PHY register definitions
- scu.h: SCU bits referenced by the SDRAM driver
- fmc_hdr.h: prebuilt-blob descriptor (binary-compatible with
arch/riscv/include/asm/arch-ast2700/fmc_hdr.h used
by the Ibex SPL)

The existing clk_register_divider() only supports linear or

When trying two ums commands in a row, the second one no longer
enumerates properly from the host.
This happens since commit
59310d1ecb9f ("usb: gadget: introduce 'enabled' flag in struct usb_ep")
causing usb_ep_enable() to return early when ep->enabled is already set.
Gadget function drivers (such as f_fastboot or f_mass_storage) implement
a disable() function which is called whenever we are done using the
gadget.
Because f_mass_storage driver does not disable the endpoints,
ep->enabled will never be set to false again.
This can be reproduced on the STM32MP157C-DK2 or the Khadas VIM3 boards.
Add calls to usb_ep_disable() as done in linux [1] to fix this.

Currently, the bi_dram[] information is stored in the board info
structure (bd). Because bd is only valid after reserve_board(),
dram_init_banksize() must be called late in the initialization process.
This limitation is problematic, as it forces us to rely on a variety of
bespoke functions to determine board RAM, bank memory sizes, and other
early setup requirements.
By moving bi_dram[] into the global data (gd), we can run it earlier.
This is particularly convenient since boards define their own
dram_init_banksize() routines, which do not always rely on parsing
Device Tree (DT) memory nodes.
Additionally, U-Boot defaults to relocating to the top of the first memory
bank. While boards currently use custom functions to override this
behavior, having the DRAM bank information available earlier in gd makes
relocating to a different bank trivial and standardizes the process.

ca_serial_getc() reads from the URX_DATA register unconditionally
without first checking whether the RX FIFO contains valid data. When
the FIFO is empty, this returns whatever stale value is in the
register, which the DM serial framework interprets as a valid
character.
The DM serial framework expects getc() to return -EAGAIN when no data
is available, so it can handle retries and call schedule() to service
the watchdog between attempts.
Add a check of the UINFO register's UINFO_RX_FIFO_EMPTY bit before
reading URX_DATA, returning -EAGAIN when no data is pending. This
is consistent with how ca_serial_putc() already checks
UINFO_TX_FIFO_FULL before writing.

Private data isn't ready during bind time. The call of dev_get_priv()
function will return NULL. Thus we can't save mdio device pointer and
use it later during probe.
To solve an issue, we will move mt7531 mdio device binding to the probing
function of 'airoha-eth' driver.
All GDM ports (except of GDM1) are connected directly to their PHYs, so
corresponding mdio bus will be automatically probed during PHY setup.
GDM1 ports differ from other GDM ports. It connected to the airoha switch
device. The mt7531 mdio bus is used to manage link state of airoha switch
device ports (LAN ports 1-4 corresponds to PHYs 0x09-0x0C). Therefore,
manual probing of mt7531 mdio bus is required to be able set/query states
of corresponding LAN ports.

The read_poll_timeout() macro breaks out of its loop when the condition
evaluates to true. The current code uses "!tx_complete" as the
condition, which means it exits immediately when tx_complete is false
(i.e., transmission has NOT completed yet), rather than waiting for
completion.
Fix the condition to "tx_complete" so that the poll loop waits until
the TCPC signals transmission success/failure/discard before
proceeding.
Without this fix, tcpm_pd_transmit() returns before the TCPC has
finished transmitting, causing the PD state machine to proceed with

This series aims to add back the omap4 support. This support was removed
by commit b0ee3fe642c ("arm: ti: Remove omap4 platform support") because
at that moment, none of the OMAP4-based boards had done the migration to
DM_I2C.
My use case is an old product based on the Variscite's omap4 system on
module. I needed to upgrade U-Boot on it for security reasons. I think
that this work could benefit to other people who may have same kind of
product to maintain.
Patch 1 to 3 remove the omap's clock driver dependency to the AM33xx
as it is also present in omap4 platforms. I tested these changes on the
beaglebone black to ensure I didn't break the AM33xx case.
Patch 4 & 5 revert the deletion of the omap4 support. The revert makes
checkpatch.pl angry. I fixed quite a lots of warnings already but it
remains two kinds of warnings:
- CamelCase on timings structure, I left the CamelCase because IMHO it's
more readable this way.
- #ifdef CONFIG_XYZ shouldn't be used anymore. I left one of this because
I didn't find a clean way to get rid of it.

they could benefit from the latest U-Boot support for obvious security

This is a DRAM controller driver for the R-Car X5H and its enablement.
This makes the U-Boot on RSIP usable beyond U-Boot shell running on
Cortex-M33, as the U-Boot on RSIP can now load not only SCP firmware
into the SCP core STCM, but also TFA BL31, OPTEE-OS and U-Boot into DRAM
and start them on the Cortex-A720AE core. This is self-contained and
affects only the R-Car X5H and a bit of R-Car V4H, besides it went
through rounds of testing until now, therefore it is safe to include it
this late in the release cycle. I know this will make rc5 massive, sorry
about that.

Add Renesas R-Car Gen5 DBSC5 DRAM controller driver. This driver is currently
capable of bringing LPDDR5X DRAM on Renesas R-Car X5H Ironhide board. Further
boards can be supported by supplying board specific DRAM configuration data
via dbsc5_get_board_data().
The driver reuses parts of previous DBSC5 driver, but due to hardware changes,
can not be fully integrated into existing DBSC and DRAM driver, therefore the
currentl DBSC and DRAM drivers are moved into R8A779G0 V4H specific files, and
the R8A78000 X5H files are added in parallel.
The Gen5 DBSC driver is meant to be used in RSIP context, while the Gen4 DBSC
driver is meant to be used in SPL, therefore the Kconfig conditionals have been
