Current dai_link related property are parsed and enabled only on CPU
port node (A)(b)(c). OTOH, Audio Graph Card2 supports many connections
like Multi-CPU, DPCM, Codec2Codec today. For example in Multi-CPU case,
it will be checked via (X) -> (B) -> (b) process, but (X) / (B) part
property is not parsed.
>From dai_link related settings point of view, (B) (C) part and Codec
port also enabled is more viscerally understandable, and useful.
card2 {
(X) links = <&snd-cpu (A)
&snd-multi (B)
&snd-dpcm (C)
...>
multi {
ports {
(B) snd-multi: port { ... };
...
};
};
dpcm {
ports {
(C) snd-dpcm: port { ... };
...
};
};
codec2codec {
...
};
};
cpu_device {
ports {
(A) snd-cpu: port { ... };
(b) mcpu: port { ... };
(c) dcpu: port { ... };
}
};
One note here is that if it was Multi-CPU/Codec case, 1st port only
enabled to have property it.

On riscv32, it is possible for the last page in virtual address space
(0xfffff000) to be allocated. This page overlaps with PTR_ERR, so that
shouldn't happen.
There is already some code to ensure memblock won't allocate the last page.
However, buddy allocator is left unchecked.
Fix this by reserving physical memory that would be mapped at virtual
addresses greater than 0xfffff000.

The TQMx86 GPIO controller uses the same register address for input and
output data. Reading the register will always return current inputs
rather than the previously set outputs (regardless of the current
direction setting). Therefore, using a RMW pattern does not make sense
when setting output values. Instead, the previously set output register
value needs to be stored as a shadow register.
As there is no reliable way to get the current output values from the
hardware, also initialize all channels to 0, to ensure that stored and
actual output values match. This should usually not have any effect in
practise, as the TQMx86 UEFI sets all outputs to 0 during boot.
Also prepare for extension of the driver to more than 8 GPIOs by using
DECLARE_BITMAP.

Now that the PLIC uses a platform driver, the driver is probed later in the
boot process, where interrupts from peripherals might already be pending.
As a result, plic_handle_irq() may be called as early as the call to
irq_set_chained_handler() completes. But this call happens before the
per-context handler is completely set up, so there is a window where
plic_handle_irq() can see incomplete per-context state and crash.
Avoid this by delaying the call to irq_set_chained_handler() until all
handlers from all PLICs are initialized.

When reading token data from sysfs on my Inspiron 3505, the token
locations and values are wrong. This happens because match_attribute()
blindly assumes that all entries in da_tokens have an associated
entry in token_attrs.
This however is not true as soon as da_tokens[] contains zeroed
token entries. Those entries are being skipped when initialising
token_attrs, breaking the core assumption of match_attribute().
Fix this by defining an extra struct for each pair of token attributes
and use container_of() to retrieve token information.

The silead touchscreen driver now defaults to 10 fingers, so it is no
longer necessary to have a "silead,max-fingers=10" property for each
silead touchscreen model. Drop this property from all the configs.

When support for Silead touchscreens was orginal added some touchscreens
with older firmware versions only supported 5 fingers and this was made
the default requiring the setting of a "silead,max-fingers=10" uint32
device-property for all touchscreen models which do support 10 fingers.
There are very few models with the old 5 finger fw, so in practice the
setting of the "silead,max-fingers=10" is boilerplate which needs to
be copy and pasted to every touchscreen config.
Reporting that 10 fingers are supported on devices which only support
5 fingers doesn't cause any problems for userspace in practice, since
at max 4 finger gestures are supported anyways. Drop the max_fingers
configuration and simply always assume 10 fingers.

Add check for the return value of of_drm_get_panel_orientation() and
return the error if it fails in order to catch the error.

The GMAC of Loongson chips cannot insert the correct 1.5-2ns delay. So
we need the PHY to insert internal delays for both transmit and receive
data lines from/to the PHY device. Fix this by changing the "phy-mode"
from "rgmii" to "rgmii-id" in dts.

In JUMP_VIRT_ADDR we are performing an or calculation on address value
directly from pcaddi.
This will only work if we are currently running from direct 1:1 mapping
addresses or firmware's DMW is configured exactly same as kernel. Still,
we should not rely on such assumption.
Fix by overriding higher bits in address comes from pcaddi, so we can
get rid of or operator.

Currently kernel entry in head.S is in DMW address range, firmware is
instructed to jump to this address after loading the kernel image.
However kernel should not make any assumption on firmware's DMW
setting, thus the entry point should be a physical address falls into
direct translation region.
Fix by converting entry address to physical and amend entry calculation
logic in libstub accordingly.
BTW, use ABSOLUTE() to calculate variables to make Clang/LLVM happy.

NUMA enabled kernel on FDT based machine fails to boot because CPUs
are all in NUMA_NO_NODE and mm subsystem won't accept that.
Fix by adding them to default NUMA node at FDT parsing phase and move
numa_add_cpu(0) to a later point.

fdt_check_header(__dtb_start) will always success because kernel
provides a dummy dtb, and by coincidence __dtb_start clashed with
entry of this dummy dtb. The consequence is fdt passed from firmware
will never be taken.
Fix by trying to utilise __dtb_start only when CONFIG_BUILTIN_DTB is
enabled.

Both acpi_table_upgrade() and acpi_boot_table_init() are defined as
empty functions under !CONFIG_ACPI_TABLE_UPGRADE and !CONFIG_ACPI in
include/linux/acpi.h, there are no implicit declaration errors with
various configs.
#ifdef CONFIG_ACPI_TABLE_UPGRADE
void acpi_table_upgrade(void);
#else
static inline void acpi_table_upgrade(void) { }
#endif
#ifdef CONFIG_ACPI
...
void acpi_boot_table_init (void);
...
#else /* !CONFIG_ACPI */
...
static inline void acpi_boot_table_init(void)
{
}
...
#endif /* !CONFIG_ACPI */
As Huacai suggested, CONFIG_ACPI_TABLE_UPGRADE is ugly and not necessary
here, just remove it. At the same time, just keep CONFIG_ACPI to prevent
potential build errors in future, and give a signal to indicate the code
is ACPI-specific. For the same reason, we also put acpi_table_upgrade()
under CONFIG_ACPI.
