Initially there was only one DSI bridge with one panel attached to this
device. This explained the call to uclass_first_device_err(UCLASS_PANEL,
...) which worked fine at the time.
Now that multiple bridges and panels, with different technologies, can
be plugged onto the board this way to get the panel device is outdated.
The lookup is done is two steps. First we circle through the
UCLASS_VIDEO_BRIDGE, and once we get one, we search through its
endpoints until we get a UCLASS_PANEL device available.

The devicetree of Samsung devices typically have the pin controller and
GPIO bank descriptors under the same pinctrl node. In U-Boot, these are
handled by two separate drivers. It is not possible to invoke both
drivers from a single node compatible.
Bind the GPIO driver on pinctrl driver bind, with the same OF node as
the pinctrl driver. This solution is already being used in other pinctrl
drivers. The hierarchy, as represented in `dm tree`, is as follows:
pinctrl@13750000
|-- gpio-banks
| |-- gpr0-gpio-bank
| |-- gpr1-gpio-bank
| |-- gpr2-gpio-bank
| |-- gpr3-gpio-bank
| `-- gpr4-gpio-bank
|-- sd0-bus-width1-pins
|-- sd0-bus-width4-pins
|-- sd0-bus-width8-pins
`-- sd0-clk-pins
Since a bind function doesn't exist, create and add it to all pinctrl
drivers.

lookup"
Rasmus Villemoes <[email protected]> says:
Hopefully third time's the charm.
I merely wanted to add support (mostly for use by the 'gpio' shell
command) for looking up a gpio via the gpio-line-names DT property. We
already have a "gpio_request_by_line_name()", but cmd/gpio.c does a
separate "lookup + request", so it felt more natural to teach the
lookup machinery this as well. That ran into
OF_CONTROL-but-not-OF_LIBFDT being a thing for SPL, so here's yet
another attempt.
Now, when trying to do my civic duty and add tests for this, I found
that test/dm/gpio.c has been defunct for a couple of years, and
reinstating it is not entirely trivial.
After a couple of rounds CI is now happy with this:
https://github.com/u-boot/u-boot/pull/828
Link: https://lore.kernel.org/r/[email protected]
|
|
In scripts as well as interactively, it's much nicer to be able to
refer to GPIOs via their names defined in the device tree property
"gpio-line-names", instead of the rather opaque names derived from the
bank name with a _xx suffix. E.g.
gpio read factory_reset FACTORY_RESET
if test $factory_reset = 1 ; then ...
versus
gpio read factory_reset gpio@481ac000_16
if test $factory_reset = 1 ; then ...
This is also consistent with the move on the linux/userspace side towards
using line names instead of legacy chip+offset or the even more legacy
global gpio numbering in sysfs.
As dev_read_stringlist_search() depends on both OF_CONTROL and
OF_LIBFDT (which matters for the SPL case), we need some .config
conditional. However, it only adds about ~50 bytes of code to U-Boot
proper, and dm_gpio_lookup_name() most often ends up being GC'ed for
SPL, thus adds no overhead there, so for now make it a hidden symbol
which is merely a convenient shorthand for
CONFIG_IS_ENABLED(OF_CONTROL) && CONFIG_IS_ENABLED(OF_LIBFDT).

Instead of resolving clock control flags using SCMI_CLOCK_ATTRIBUTES
during probe for each and every clock, resolve the clock control
flags using SCMI_CLOCK_ATTRIBUTES when the clock control flags are
first used. Because most clock are never used by U-Boot, this allows
reducing the amount of SCMI_CLOCK_ATTRIBUTES considerably, and this
improve probe time of the scmi clock driver and U-Boot start up time.

The clock names are retrived via SCMI_CLOCK_ATTRIBUTES, called for each
clock ID. This may take a lot of time to complete and is not strictly
necessary. Register each clock as "scmi-%zu" instead, and let the first
call of SCMI_CLOCK_ATTRIBUTES fill in the actual clock name.
This has a side effect, which can be considered both an upside and also
a downside. Unused clock are never renamed and retain their placeholder
"scmi-%zu" name, which avoids empty clock names for nameless SCMI clock,
and avoids the name resolution and improves boot time. But for those
SCMI clock which do have name, that name is not listed until the clock
are used.

Allocate all sub-driver instance data at once. The amount of data that
have to be allocated is known up front, so is the size of the data, so
there is no need to call malloc() in a loop, mallocate all data at once.
The upside is, less heap fragmentation and fewer malloc() calls overall,
and a faster boot time.
The downside is, if some of the clock fail to register, then the clock
driver cannot free parts of the bulk allocated sub-driver instance data.
Such a failure can only occur if clk_register() were to fail, and if that
happens, the system has more significant problems. Worse, if a core clock
driver fails to probe, the system has even bigger problem.

able to run 32-bit OS only.
This patch series adds support for the following hardware:
* console UART
* ethernet controller/switch
* spinand flash (in non-dma mode)
The following issues may be expected:
* Extra slow UBI attaching in U-Boot (up to 20 sec with fastmap enabled).
This is caused by the lack of DMA support in the U-Boot airoha-snfi driver.
* Linux airoha-snfi driver in some cases might damage you flash data
(see: https://lore.kernel.org/lkml/[email protected]/)
* Latest linux kernel is recommended to properly support flashes
with more than one plane per lun
(see: https://lore.kernel.org/lkml/[email protected]/)
* It's NOT recommended to use flashes working in continuous mode because
U-Boot airoha-snfi driver does not support such flashes properly.

- RAM: 512 MB
