The RZ/V2M SoC contains an External Power Sequence Controller (PWC) module. This module provides an external power supply on/off sequence, on/off signal for the LPDDR4 core power supply, General Purpose Outputs, and key input signals. This patch adds PWC support to the SoC specific device tree. Signed-off-by:

Although of_fdt_device_is_available returns true when the DT property "status" is assigned "ok" or "okay", and false for every other value, it's become common practice to assign "disabled" when we want of_fdt_device_is_available to return false. For some reason, the status property of the ethernet node was assigned "disable" when originally added to the kernel. Change it to "disabled" for consistency. Signed-off-by:

The WM8962 is configured so the SoC is driving the clock, and it's currently set to 24 MHz. However, when playing audio it shows the following message: wm8962 5-001a: Unsupported sysclk ratio 500 While not harmful, a better clock ratio is 512. It makes the message disappear, and it still plays sound. Signed-off-by:Adam Ford <aford173@gmail.com> Reviewed-by:

Due to the part shortage, the AR8031 PHY was replaced with a Micrel KSZ9131. Hard-coding the ID of the PHY makes this new PHY non-operational on newer hardware. Since previous hardware had only shipped to a limited number of people, and they have not gone to production, it should be safe to update the PHY ID. Signed-off-by:

The board used to originally introduce the Beacon Embedded RZ/G2[M/N/H] boards had a GPIO expander with address 20, but this was changed when the final board went to production. The production boards changed both the part itself and the address. With the incorrect address, the LCD cannot come up. If the LCD fails, the rcar-du driver fails to come up, and that also breaks HDMI. Pre-release board were not shipped to the general public, so it should be safe to push this as a fix. Anyone with a production board would have video fail due to this GPIO expander change. Fixes: a1d8a344 ("arm64: dts: renesas: Introduce r8a774a1-beacon-rzg2m-kit") Signed-off-by:

ALSA SoC has many types of Generic Audio Card drivers (Simple Audio Card, Audio Graph Card, Audio Graph Card2), and Renesas/Kuninori Morimoto wants to test these. The Generic Audio Card driver had been requested on ALSA SoC. It supports many types of device connection methods, and historically, the requested connection support range of the generic driver has been upgraded. Upgrading the connection support range itself could not be implemented in the generic driver, because we need to keep compatibility with old DTBs. This is one of the reasons why we have many types of Generic Audio Card driver. The ULCB/KF combo is a good board stack to test these. Kuninori has been testing these Generic Audio Card drivers by using his local patches to switching drivers. But from an information sharing point of view, it is a good idea to upstream these, because the DT configuration is complex. Hence this can be a good sample for the user. Hence add a "Simple Audio Card + MIXer + TDM Split" DT setting file for ULCB/KF. Because of the limited number of subdevices, the HDMI output is ignored. This setting can be enabled by updating ulcb.dtsi / ulcb-kf.dtsi. From a normal user point of view who doesn't need to test the driver, everything should stay as-is, and nothing changes. Note that because this needs "switching driver", and not "adding extra feature", this does not use a Device Tree overlay. Signed-off-by:

There is a generic clock called CPG_AUDIO_CLK_I defined in each of the SoC DTSI files which points to this unique clock. By using that, the clock information for the rcar_sound can be consolidated into the baseboard file and have it reference this generic clock thus removing the duplication from the three variants.

Enable WDT node on RZ/Five SMARC SoM. Note, WDT block is enabled in RZ/G2UL SMARC SoM DTSI [0] hence deleting the disabled node from RZ/Five SMARC SoM DTSI enables it here too as we include [0] in RZ/Five SMARC SoM DTSI. [0] arch/arm64/boot/dts/renesas/rzg2ul-smarc-som.dtsi Signed-off-by:

Due to several bugs caused by timers being re-armed after they are shutdown and just before they are freed, a new state of timers was added called "shutdown". After a timer is set to this state, then it can no longer be re-armed. The following script was run to find all the trivial locations where del_timer() or del_timer_sync() is called in the same function that the object holding the timer is freed. It also ignores any locations where the timer->function is modified between the del_timer*() and the free(), as that is not considered a "trivial" case. This was created by using a coccinelle script and the following commands: $ cat timer.cocci @@ expression ptr, slab; identifier timer, rfield; @@ ( - del_timer(&ptr->timer); + timer_shutdown(&ptr->timer); | - del_timer_sync(&ptr->timer); + timer_shutdown_sync(&ptr->timer); ) ... when strict when != ptr->timer ( kfree_rcu(ptr, rfield); | kmem_cache_free(slab, ptr); | kfree(ptr); ) $ spatch timer.cocci . > /tmp/t.patch $ patch -p1 < /tmp/t.patch Link: https://lore.kernel.org/lkml/20221123201306.823305113@linutronix.de/ Signed-off-by:Steven Rostedt (Google) <rostedt@goodmis.org> Acked-by: Pavel Machek <pavel@ucw.cz> [ LED ] Acked-by: Kalle Valo <kvalo@kernel.org> [ wireless ] Acked-by: Paolo Abeni <pabeni@redhat.com> [ networking ] Signed-off-by:
