efb5dab7ba nxp: Migrate CONFIG_DDR_CLK_FREQ to Kconfig
As this symbol can either be a fixed value or the function
get_board_ddr_clk, migration is tricky.  Introduce a choice of DYNAMIC
or STATIC_DDR_CLK_FREQ.  If DYNAMIC, we continue to use the board
defined get_board_ddr_clk function.  If STATIC, set CONFIG_DDR_CLK_FREQ
to that value and now include/clock_legacy.h contains the function
prototype or defines get_board_ddr_clk() to that static value.  Update
callers to test for DYNAMIC or STATIC.

2ac8490412 watchdog: add gpio watchdog driver
A rather common kind of external watchdog circuit is one that is kept
alive by toggling a gpio. Add a driver for handling such a watchdog.

The corresponding linux driver apparently has support for some
watchdog circuits which can be disabled by tri-stating the gpio, but I
have never actually encountered such a chip in the wild; the whole
point of adding an external watchdog is usually that it is not in any
way under software control. For forward-compatibility, and to make DT
describe the hardware, the current driver only supports devices that
have the always-running property. I went a little back and forth on
whether I should fail ->probe or only ->start, and ended up deciding
->start was the right place.

The compatible string is probably a little odd as it has nothing to do
with linux per se - however, I chose that to make .dts snippets
reusable between device trees used with U-Boot and linux, and this is
the (only) compatible string that linux' corresponding driver and DT
binding accepts. I have asked whether one should/could add "wdt-gpio"
to that binding, but the answer was no:

  https://lore.kernel.org/lkml/CAL_JsqKEGaFpiFV_oAtE+S_bnHkg4qry+bhx2EDs=NSbVf_giA@mail.gmail.com/

If someone feels strongly about this, I can certainly remove the
"linux," part from the string - it probably wouldn't the only place where
one can't reuse a DT snippet as-is between linux and U-Boot.

492ee6b8d0 watchdog: wdt-uclass.c: handle all DM watchdogs in watchdog_reset()
A board can have and make use of more than one watchdog device, say
one built into the SOC and an external gpio-petted one. Having
wdt-uclass only handle the first is both a little arbitrary and
unexpected.

So change initr_watchdog() so we visit (probe) all DM watchdog
devices, and call the init_watchdog_dev helper for each.

Similarly let watchdog_reset() loop over the whole uclass - each
having their own ratelimiting metadata, and a separate "is this device
running" flag.

This gets rid of the watchdog_dev member of struct global_data.  We
do, however, still need the GD_FLG_WDT_READY set in
initr_watchdog(). This is because watchdog_reset() can get called
before DM is ready, and I don't think we can call uclass_get() that
early.

The current code just returns 0 if "getting" the first device fails -
that can of course happen because there are no devices, but it could
also happen if its ->probe call failed. In keeping with that, continue
with the handling of the remaining devices even if one fails to
probe. This is also why we cannot use uclass_probe_all().

If desired, it's possible to later add a per-device "u-boot,autostart"
boolean property, so that one can do CONFIG_WATCHDOG_AUTOSTART
per-device.

90555dc83e watchdog: wdt-uclass.c: add wdt_stop_all() helper
Since the watchdog_dev member of struct global_data is going away in
favor of the wdt-uclass handling all watchdog devices, prepare for
that by adding a helper to call wdt_stop() on all known devices.

If an error is encountered, still do wdt_stop() on remaining devices,
but remember and return the first error seen.

Initially, this will only be used in one single
place (board/alliedtelesis/x530/x530.c).

f1b112afbb watchdog: wdt-uclass.c: keep track of each device's running state
As a step towards handling all DM watchdogs in watchdog_reset(), use a
per-device flag to keep track of whether the device has been started
instead of a bit in gd->flags.

We will still need that bit to know whether we are past
initr_watchdog() and hence have populated gd->watchdog_dev -
incidentally, that is how it was used prior to commit 9c44ff1c5f.

6d24dc89f0 watchdog: wdt-uclass.c: introduce struct wdt_priv
As preparation for having the wdt-uclass provided watchdog_reset()
function handle all DM watchdog devices, and not just the first such,
introduce a uclass-owned struct to hold the reset_period and
next_reset, so these become per-device instead of being static
variables.

8967ebb653 watchdog: wdt-uclass.c: use wdt_start() in wdt_expire_now()
wdt_start() does the "no ->start? return -ENOSYS" check, don't
open-code that in wdt_expire_now().

Also, wdt_start() maintains some global (and later some per-device)
state, which would get out of sync with this direct method call - not
that it matters much here since the board is supposed to reset very
soon.

b6f44082d5 mmc: zynq_sdhci: Wait till sd card detect state is stable
As per SD spec when SD host controller is reset, it takes 1000msec
to detect the card state. In case, if we enable the sd bus voltage &
card detect state is not stable, then host controller will disable
the sd bus voltage.

In case of warm/subsystem reboot, due to unstable card detect state
host controller is disabling the sd bus voltage to sd card causing
sd card timeout error. So we wait for a maximum of 1000msec to get
the card detect state stable before we enable the sd bus voltage.

This current fix is workaround for now, this needs to be analysed
further. Zynqmp platform should behave the same as Versal, but we
did not encounter this issue as of now. So we are fixing it for
Versal only.

655d69faaf mmc: zynq_sdhci: Move setting tapdelay code to driver
Move tapdelay function calls to zynq_sdhci.c and make them static
inline. zynqmp_tap_delay.h has function prototypes for the functions
defined in tap_delays.c, which will not be needed anymore.

Remove tap_delays.c and zynqmp_tap_delay.h files.

d044982555 mmc: zynq_sdhci: Add xilinx_pm_request() method to set tapdelays
Currently xilinx sdhci driver is using zynqmp_mmio_write() to set
tapdelay values and DLL resets. Continue to use this for SPL and mini
U-Boot where U-Boot will be executed at EL3 level.

Use firmware call xilinx_pm_request() using appropriate arguments to
set input/output tapdelays and also for DLL resets in regular flow(EL2).

Host driver should explicitly request DLL reset before ITAP (assert DLL)
and after OTAP (release DLL) to avoid issues in some cases. Also handle
error return where possible.

59d4230429 ddr: altera: Add SDRAM driver for Intel N5X device
The DDR subsystem in Diamond Mesa is consisted of controller, PHY,
memory reset manager and memory clock manager.

Configuration settings of controller, PHY and  memory reset manager
is come from DDR handoff data in bitstream, which contain the register
base addresses and user settings from tool.

Configuration settings of memory clock manager is come from the HPS
handoff data in bitstream, however the register base address is defined
in device tree.

The calibration is fully done in HPS, which requires IMEM and DMEM
binaries loading to PHY SRAM for running this calibration, both
IMEM and DMEM binaries are also part of bitstream, this bitstream
would be loaded to OCRAM by SDM, and configured by DDR driver.
