[PATCH 01/20] imx8ulp: soc: Check the DBD_EN fuse before setting RDC

[Peng Fan (OSS)]

From: Ye Li <ye.li@nxp.com>

S400 enables RDC only when the DBD_EN is fused. Otherwise, the RDC
is allowed by all masters.

Current S400 has issue if the XRDC has released to A35, then A35 reset
will fail in ROM due to S400 fails to get XRDC.
So temp work around is checking the DBD_EN, if it is not fused, we
don't need to call release XRDC or TRDC.

[PATCH 07/20] imx8ulp_evk: Control LPI2C0 PCA6416 and TPM0 for display

[Peng Fan (OSS)]

From: Ye Li <ye.li@nxp.com>

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.

[PATCH 11/20] imx8ulp: Workaround LPOSC_TRIM fuse load issue

[Peng Fan (OSS)]

From: Ye Li <ye.li@nxp.com>

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.

The LPAV is not allocated to APD when dual boot, so LPAV won't

otherwise its initialization will fail.

[PATCH 16/20] imx8ulp: clock: Handle the DDRLOCKED when setting DDR clock

[Peng Fan (OSS)]

From: Ye Li <ye.li@nxp.com>

The DDRLOCKED bit in CGC2 DDRCLK will auto lock up and down by HW
according to DDR DIV updating or DDR CLK halt status change. So DDR
PCC disable/enable will trigger the lock up/down flow. We
need wait until unlock to ensure clock is ready.

And before configuring the DDRCLK DIV, we need polling the DDRLOCKED
until it is unlocked. Otherwise writing ti DIV bits will not set.

[PATCH 20/20] imx8ulp: ddr: Fix DDR frequency request issue

[Peng Fan (OSS)]

From: Ye Li <ye.li@nxp.com>

After acking the requested frequency, should wait the ack bit clear
by DDR controller and check the DFS interrupt for next request polling.
Otherwise, the next polling of request bit will get previous value
that DDR controller have not cleared it, so a wrong request frequency
is used.

[PATCH 16/20] imx8ulp: clock: Handle the DDRLOCKED when setting DDR clock

[sbabic]

> From: Ye Li <ye.li@nxp.com>
> The DDRLOCKED bit in CGC2 DDRCLK will auto lock up and down by HW
> according to DDR DIV updating or DDR CLK halt status change. So DDR
> PCC disable/enable will trigger the lock up/down flow. We
> need wait until unlock to ensure clock is ready.
> And before configuring the DDRCLK DIV, we need polling the DDRLOCKED
