[PATCH 5.10 031/188] ARM: dts: turris-omnia: configure LED[2]/INTn pin as interrupt pin

[Greg Kroah-Hartman]

From: Marek Behún <kabel@kernel.org>

commit a26c56ae67fa9fbb45a8a232dcd7ebaa7af16086 upstream.

Use the `marvell,reg-init` DT property to configure the LED[2]/INTn pin
of the Marvell 88E1514 ethernet PHY on Turris Omnia into interrupt mode.

Without this the pin is by default in LED[2] mode, and the Marvell PHY
driver configures LED[2] into "On - Link, Blink - Activity" mode.

This fixes the issue where the pca9538 GPIO/interrupt controller (which
can't mask interrupts in HW) received too many interrupts and after a
time started ignoring the interrupt with error message:
  IRQ 71: nobody cared

There is a work in progress to have the Marvell PHY driver support
parsing PHY LED nodes from OF and registering the LEDs as Linux LED
class devices. Once this is done the PHY driver can also automatically
set the pin into INTn mode if it does not find LED[2] in OF.

Until then, though, we fix this via `marvell,reg-init` DT property.

[PATCH 5.10 130/188] ASoC: sunxi: sun4i-codec: fill ASoC card owner

[Greg Kroah-Hartman]

From: Bastian Germann <bage@linutronix.de>

[ Upstream commit 7c0d6e482062eb5c06ecccfab340abc523bdca00 ]

card->owner is a required property and since commit 81033c6b584b ("ALSA:
core: Warn on empty module") a warning is issued if it is empty. Add it.
This fixes following warning observed on Lamobo R1:

WARNING: CPU: 1 PID: 190 at sound/core/init.c:207 snd_card_new+0x430/0x480 [snd]
Modules linked in: sun4i_codec(E+) sun4i_backend(E+) snd_soc_core(E) ...
CPU: 1 PID: 190 Comm: systemd-udevd Tainted: G         C  E     5.10.0-1-armmp #1 Debian 5.10.4-1
Hardware name: Allwinner sun7i (A20) Family
