7b68357130 imx: imx8ulp_evk: call the handshake with M33
If M33 handshake is successful, TPM and DSI panel MUX setting is
done by M33, no need to set them.
If handshake is failed or M33 is not booted, continue the TPM
and DSI panel MUX setting

3524540e70 imx: imx8ulp: Load the lposc fuse for dual boot
Found the lposc fuse loading having impact to cpu idle in kernel.
Without the loading in dual boot mode, kernel will hang after idle
for a while.

4ab38f6822 imx: imx8ulp_evk: Skip init DDR for reboot in dual boot mode
When M33 is LPAV owner in dual boot, DDR, PCC5, CGC2 won't be reset
during APD reset. So no need to init DDR again after reboot, but need to
reconfigure the PLL4 PFD/PFDDIV/LPAV NIC etc, because kernel may
change or disable some of them.

a092f33305 imx: imx8ulp: add ND/LD clock
Add a new ddr script, defconfig for ND
Configure the clock for ND mode
changing A35 to 960MHz for OD mode
Update NIC CLK for the various modes
Introduce clock_init_early/late, late is used after pmic voltage
setting, early is used in the very early stage for upower mu, lpuart and
etc.

Note: NIC runs at 324MHz, 442MHz has some random kernel hang issue with
cpuidle enabled now.

4ddb33dac5 imx: imx8ulp_evk: Remove PMIC Bucks PWM mode settings
This workaround is not needed on i.MX8ULP proto-1B EVK as board has
fixed the problem. Because we don't support proto-1A any longer,
remove the PMIC settings.

9c7fbebe5d imx8ulp: Workaround LPOSC_TRIM fuse load issue
8ULP ROM should read the LPOSC trim BIAS fuse to fill the CGC0
LPOSCCTRL[7:0], but it writes a fixed value on A0.1 revision.

A0.2 will fix the issue in ROM. But A0.1 we have to workaround
it in SPL by setting LPOSCCTRL BIASCURRENT again.

9dde390be6 imx8ulp_evk: Control LPI2C0 PCA6416 and TPM0 for display
The board use IO9 of PCA6416 on LPI2C0 and TPM0 for MIPI DSI MUX and
backlight. However the LPI2C0 and TPM0 are M33 resources, in this
patch we simply access them, but this is a temporary solution.
We will modify it when M33 FW changes to set MIPI DSI panel as default
path and enable backlight after reset.

Log as below: I would keep some debug info for now, and after we move
