serial: meson: fix meson_serial_pending() tx logic

According to the dm_serial_ops documentation, pending() should:
> @return number of waiting characters, 0 for none, -ve on error

And:
> It is acceptable to return 1 if an indeterminant number
> of characters is waiting.

With the current implementation, we have:
* FIFO is full           -> pending() returns 0
* FIFO is partially used -> pending() returns 1
* FIFO is empty          -> pending() returns 1

This is not the same as what the documentation requires.

Moreover, since [1], arm reset now flushes all console devices
(including serial) before the cpu gets reset.
Because of the flawed logic:

  => reset # user calls reset
  flush() is called
  _serial_flush() is called
  ops->pending(dev, false) # never returns false
  # board hangs indefinitely without resetting.

Fix it by using AML_UART_TX_EMPTY instead of AML_UART_TX_FULL.

I2C: cdns: Fix broken retry mechanism on arbitration lost.

In the current implementation, in case of I2C arbitration lost, a retry is
attempted; the message counter and pointer are reset to the original values
and the I2C xfer process is restart from the beginning.

However the message counter and message pointer are respectively
decremented and incremented by one before attempting any transfer, causing
the 1st transfer not to be actually retried (in case of a single transfer,
nothing is actually retried at all).

This patch fixes this: in case of retry, the 1st transfer is also retried.

Tested on a ZynqMP Kria board, with upstream older u-boot, but the involved

arm: mach-k3: security: separate out validating binary logic

K3 GP devices allows booting the secure binaries on them by bypassing
the x509 header on them.

ATF and OPTEE firewalling required the rproc_load to be called before
authentication. This change caused the failure for GP devices that
strips off the headers. The boot vector had been set before the headers
were stripped off causing the runtime stripping to fail and stripping
becoming in-effective.

Separate out the secure binary check on GP/HS devices so that the
boot_vector could be stripped before calling rproc_load. This allows
keeping the authentication later when the cluster is on along with
allowing the stripping of the binaries in case of gp devices.

ddr: imx9: Add workaround for DDRPHY rank-to-rank errata

According to DDRPHY errata, the Rank-to-Rank Spacing and tphy_rdcsgap
specification does not include the Critical Delay Difference (CDD) to
properly define the required rank-to-rank read command spacing after
executing PHY training firmware.

Following the errata workaround, at the end of data training, we get
all CDD values through the MessageBlock, then re-configure the DDRC
timing of WWT/WRT/RRT/RWT with comparing MAX CDD values.

reset: rockchip: implement rk3588 lookup table

The current DT bindings for the rk3588 clock use a different ID than the
one that is supposed to be written to the hardware registers.
Thus, we cannot use directly the id provided in the phandle, but rather
use a lookup table to correctly setup the hardware.

This approach has been implemented already in Linux, by commit :
f1c506d152ff ("clk: rockchip: add clock controller for the RK3588")

Hence, implement a similar approach using the lookup table, and adapt
the existing reset driver to work with SoCs using lookup table.
The file rst-rk3588.c has been copied as much as possible from Linux.

Adapt the clk rk3588 driver as well to bind the reset driver with the
lookup table.
