powerpc/powernv: Free name on error in opal_event_init()

2024-11-17T13:58:53+00:00

[ Upstream commit cf8989d20d64ad702a6210c11a0347ebf3852aa7 ]

In opal_event_init() if request_irq() fails name is not freed, leading
to a memory leak. The code only runs at boot time, there's no way for a
user to trigger it, so there's no security impact.

Fix the leak by freeing name in the error path.

ARM: dts: rockchip: Fix the realtek audio codec on rk3036-kylin

2024-11-17T13:58:50+00:00

[ Upstream commit 77a9a7f2d3b94d29d13d71b851114d593a2147cf ]

Both the node name as well as the compatible were not named
according to the binding expectations, fix that.

ARM: dts: rockchip: Fix the spi controller on rk3036

2024-11-17T13:58:50+00:00

[ Upstream commit 8bade1ad1f0821aef31f6a8fb1027ae292566d85 ]

Compatible and clock names did not match the existing binding.
So set the correct values and re-order+rename the clocks.

It looks like no rk3036 board did use the spi controller so far,
so this was never detected on a running device yet.

ARM: dts: rockchip: drop grf reference from rk3036 hdmi

Neither the binding nor the driver implementation specify/use the grf
reference provided in the rk3036. And neither does the newer rk3128
user of the hdmi controller. So drop the rockchip,grf property.

Set the correct nodename, use the correct compatible, add the needed

arm64: dts: rockchip: Remove #cooling-cells from fan on Theobroma lion

2024-11-17T13:58:49+00:00

[ Upstream commit 5ed96580568c4f79a0aff11a67f10b3e9229ba86 ]

All Theobroma boards use a ti,amc6821 as fan controller.
It normally runs in an automatically controlled way and while it may be
possible to use it as part of a dt-based thermal management, this is
not yet specified in the binding, nor implemented in any kernel.

Newer boards already don't contain that #cooling-cells property, but
older ones do. So remove them for now, they can be re-added if thermal
integration gets implemented in the future.

There are two further occurences in v6.12-rc in px30-ringneck and
rk3399-puma, but those already get removed by the i2c-mux conversion
scheduled for 6.13 . As the undocumented property is in the kernel so
long, I opted for not causing extra merge conflicts between 6.12 and 6.13

arm64: dts: rockchip: Remove hdmi's 2nd interrupt on rk3328

2024-11-17T13:58:49+00:00

[ Upstream commit de50a7e3681771c6b990238af82bf1dea9b11b21 ]

The "synopsys,dw-hdmi.yaml" binding specifies that the interrupts
property of the hdmi node has 'maxItems: 1', so the hdmi node in
rk3328.dtsi having 2 is incorrect.

Paragraph 1.3 ("System Interrupt connection") of the RK3328 TRM v1.1
page 16 and 17 define the following hdmi related interrupts:
-  67 hdmi_intr
- 103 hdmi_intr_wakeup

The difference of 32 is due to a different base used in the TRM.

The RK3399 (which uses the same binding) has '23: hdmi_irq' and
'24: hdmi_wakeup_irq' according to its TRM (page 19).
The RK3568 (also same binding) has '76: hdmi_wakeup' and '77: hdmi'
according to page 17 of its TRM.
In both cases the non-wakeup IRQ was used, so use that too for rk3328.
