5.15-2.2.x: lpuart still not working

Since the fix and merge of #621 happened so fast, I was able to test it today. Sadly, it does not work. This time the results are different - no error happens, but console output just plain stops after some diagnostic messages from the driver.

This is the last of what I see:

[    1.198118] 5a060000.serial: ttyLP0 at MMIO 0x5a060010 (irq = 74, base_baud = 5000000) is a FSL_LPUART
[    1.208224] 5a070000.serial: ttyLP1 at MMIO 0x5a070010 (irq = 75, base_baud = 5000000) is a FSL_LPUART

I have no clue as to why this happens. What fixes this for me is moving uart_add_one_port() before lpuart_global_reset(). So, where before #621 there were two calls to add_one_port(), and the patch removed the first one while reordering cleanup, what works for me is removing the second call and leaving cleanup as-is.

If necessary, I can create a PR later tonight.

I.MX8QM-EVK Fails to boot due to mmc not getting probed

Hi,

I was trying to boot an I.MX8QM-EVK board with 6.6-1.0.x-imx and getting problems due to the MMC not getting probed, thus being unable to mount rootfs. The kernel output was the following:

[    3.342228] sdhci-esdhc-imx: probe of 5b020000.mmc failed with error -2

It seemed like the mmc clock has an index problem. From further investigation and comparing this repo with linux-imx I found that the clk index's were changed on the usdhc* devices. For example, usdhc1 on the file imx8-ss-conn.dtsi:

linux-imx:

	usdhc1: mmc@5b010000 {
		interrupts = <GIC_SPI 232 IRQ_TYPE_LEVEL_HIGH>;
		reg = <0x5b010000 0x10000>;
		clocks = <&sdhc0_lpcg 1>,
			 <&sdhc0_lpcg 2>,
			 <&sdhc0_lpcg 0>;
		clock-names = "ipg", "ahb", "per";
		assigned-clocks = <&clk IMX_SC_R_SDHC_0 IMX_SC_PM_CLK_PER>;
		assigned-clock-rates = <400000000>;
		power-domains = <&pd IMX_SC_R_SDHC_0>;
		fsl,tuning-start-tap = <20>;
		fsl,tuning-step= <2>;
		status = "disabled";
	};

linux-fslc:

	usdhc1: mmc@5b010000 {
		interrupts = <GIC_SPI 232 IRQ_TYPE_LEVEL_HIGH>;
		reg = <0x5b010000 0x10000>;
		clocks = <&sdhc0_lpcg IMX_LPCG_CLK_4>,
			 <&sdhc0_lpcg IMX_LPCG_CLK_5>,
			 <&sdhc0_lpcg IMX_LPCG_CLK_0>;
		clock-names = "ipg", "ahb", "per";
		assigned-clocks = <&clk IMX_SC_R_SDHC_0 IMX_SC_PM_CLK_PER>;
		assigned-clock-rates = <400000000>;
		power-domains = <&pd IMX_SC_R_SDHC_0>;
		fsl,tuning-start-tap = <20>;
		fsl,tuning-step= <2>;
		status = "disabled";
	};

Both repo's have the IMX_LPCG_CLK* defines in the file include/dt-bindings/clock/imx8-lpcg.h. Changing the index's to match imx's made it so the MMC got correctly probed and the board booted.
Comparing with mainline, I noticed that linux-fslc seems to be missing these index's in the lpcg's. Example:

linux-fslc:

	sdhc0_lpcg: clock-controller@5b200000 {
		compatible = "fsl,imx8qxp-lpcg";
		reg = <0x5b200000 0x10000>;
		#clock-cells = <1>;
		clocks = <&clk IMX_SC_R_SDHC_0 IMX_SC_PM_CLK_PER>,
			 <&conn_ipg_clk>, <&conn_axi_clk>;
		bit-offset = <0 16 20>;
		clock-output-names = "sdhc0_lpcg_per_clk",
				     "sdhc0_lpcg_ipg_clk",
				     "sdhc0_lpcg_ahb_clk";
		power-domains = <&pd IMX_SC_R_SDHC_0>;
	};

linux:

	sdhc0_lpcg: clock-controller@5b200000 {
		compatible = "fsl,imx8qxp-lpcg";
		reg = <0x5b200000 0x10000>;
		#clock-cells = <1>;
		clocks = <&clk IMX_SC_R_SDHC_0 IMX_SC_PM_CLK_PER>,
			 <&conn_ipg_clk>, <&conn_axi_clk>;
		clock-indices = <IMX_LPCG_CLK_0>, <IMX_LPCG_CLK_4>,
				<IMX_LPCG_CLK_5>;
		clock-output-names = "sdhc0_lpcg_per_clk",
				     "sdhc0_lpcg_ipg_clk",
				     "sdhc0_lpcg_ahb_clk";
		power-domains = <&pd IMX_SC_R_SDHC_0>;
	};

From what I can see mainline opt's to use clock-indices and IMX_LPCG_CLK* defines while NXP uses bit-offset's and no IMX_LPCG_CLK* defines. But in this repo a mixture of both is used, thus not working properly.
I am not very familiar with the clock subsystem on Linux and thus, could be misinterpreting the way this is working, but reverting the macros made the board boot again, so something must be wrong.

PS: The issue happens in every device that uses the IMX_LPCG_CLK* macros, although none beside the mmc prevent the board from booting.

kill drm application, system crash

My current test program uses the DRM framework. When I test, I find that when I kill my display program with the kill command, the system will crash

Issue to put kernel branch 4.9-1.0.x-imx in imx7d-pico with linux-fslc with Kernel 6.6

**Hi,

I stay running linux-fslc (Linux imx7d-pico 6.6.0-fslc-fslc-00010-g34836895e19e #1 SMP Mon Oct 30)
and U-Boot 2023.10+fslc+g105a9c8cc0 in my imx7d-pico device by TechNexion.
based in this tutorial: https://imxdev.gitlab.io/ann/The_imx7d-pico_board_is_now_supported_in_FSL_Community_BSP/

My problems start when I try to use rpmsg-lite.

Firstly I tried to insert the settings below in this kernel version and I was unable to do so:

CONFIG_HAVE_IMX_MU=y
CONFIG_HAVE_IMX_RPMSG=y
CONFIG_RPMSG=y
CONFIG_RPMSG_VIRTIO=y
CONFIG_IMX_RPMSG_PINGPONG=m
CONFIG_IMX_RPMSG_TTY=m

Afterwards (I've been trying for 2 weeks) I tried to put/port kernel 4.9-1.0.x-imx (https://github.com/diegosueiro/linux-fslc/tree/4.9-1.0.x-imx)

If the way mentioned above works, I will certainly be successful as the compilation of the zephyr-m4-side bin file is almost ready

Below are the errors I currently get when trying to port the kernel (from 6.6 to 4.9) and a screenshot**

E.g.: I'm putting the 4.9 kernel in a local folder on my computer (with all authorizations and permissions, ssh, git user, etc) and creating a *.bbappend with:

FILESEXTRAPATHS:prepend := "${THISDIR}/${PN}:"

SRC_URI = "git://srv/git/linux.git;branch=scorpion_test2"
KBRANCH =  "scorpion_test2"
#SRCBRANCH =  "scorpion_test2"
##SRCPV  = "scorpion_test"
SRCREV = "${AUTOREV}"

My issue is below:

mipi_dsi missing from imx8mm.dtsi

Is there a reason why the mipi_dsi node is missing from imx8mm.dtsi in linux-fslc while it is present in linux-fslc-imx?
If it's missing for no reason, I will make a PR to resolve this
