When a pin is muxed to a peripheral or as a GPIO, the only
configuration that can be set is the pullup. It is too restrictive
so this patch allows to give a full configuration.

Add support for the device tree property "default-state". This feature
might be useful for LEDs indicating "power on" or similar states.
Note: Even with this commit gpio-leds remain in reset state. That's
because the led_gpio is not probed until DM_FLAG_ACTIVATED is set.

mmc_set_clock() function has the disable argument as bool type.
When mmc_set_clock is called, it might be passed to "true" or "false".
But it's too confusion whether clock is enabled or disabled with only
"true" and "false".
To prevent the confusion, replace to MMC_CLK_ENABLE/DISABLE macro from
true/false.

Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under
armv7 folder. This led to a misconception of creating separate folders
for armv7m and armv7r. There is no reason to create separate folder for
other armv7 based architectures when it can co-exist with few Kconfig
symbols.
As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later
separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.

The syscon implementation in U-Boot is different from that in Linux.
Thus, DT files imported from Linux do not work for U-Boot.
In U-Boot driver model, each node is bound to a dedicated driver
that is the most compatible to it. This design gets along with the
concept of DT, and the syscon in Linux originally worked like that.
However, Linux commit bdb0066df96e ("mfd: syscon: Decouple syscon
interface from platform devices") changed the behavior because it is
useful to let a device bind to another driver, but still work as a
syscon provider.
That change had happened before U-Boot initially supported the syscon
driver by commit 6f98b7504f70 ("dm: Add support for generic system
controllers (syscon)"). So, the U-Boot's syscon works differently
from the beginning. I'd say this is mis-implementation given that
DT is not oriented to a particular project, but Linux is the canon
of DT in practice.
The problem typically arises in the combination of "syscon" and
"simple-mfd" compatibles.
In Linux, they are orthogonal, i.e., the order between "syscon" and
"simple-mfd" does not matter at all.
Assume the following compatible.
compatible = "foo,bar-syscon", "syscon", "simple-mfd";
In U-Boot, this device node is bound to the syscon driver
(driver/core/syscon-uclass.c) since the "syscon" is found to be the
most compatible. Then, syscon_get_regmap() succeeds.
However,
compatible = "foo,bar-syscon", "simple-mfd", "syscon";
does not work because this node is bound to the simple-bus driver
(drivers/core/simple-bus.c) in favor of "simple-mfd" compatible.
The compatible string "syscon" is just dismissed.
Moreover,
compatible = "foo,bar-syscon", "syscon";
works like the first case because the syscon driver populates the
child devices. This is wrong because populating children is the job
of "simple-mfd" (or "simple-bus").
This commit ports syscon_node_to_regmap() from Linux. This API
does not require the given node to be bound to a driver in any way.

Putting zero length array at the end of struct is a common technique
to embed arbitrary length of members. There is no good reason to let
regmap_alloc_count() branch by "if (count <= 1)".
As far as I understood the code, regmap->base is an alias of
regmap->ranges[0].start, but it is not helpful but make the code
just ugly.
Rename regmap_alloc_count() to regmap_alloc() because the _count
suffix seems pointless.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document. Note that parenthesis are
allowed so when they were used before we continue to use them.

The 'SDHCI_QUIRK_NO_HISPD_BIT' is used wrong here. The purpose of this
quirk is to tell the sdhci-driver that the IP-core doesn't have a "high-
speed-enable" bit in its registers.
With this commit we change this to the correct quirk:
SDHCI_QUIRK_BROKEN_HISPD_MODE
Signed-off-by: Hannes Schmelzer <[email protected]>
|

Some IP-core implementations of the SDHCI have different troubles on the
silicon where they are placed.
On ZYNQ platform for example Xilinx doesn't accept the hold timing of an
eMMC chip which operates in High-Speed mode and must be forced to
operate in non high-speed mode. To get rid of this
"SDHCI_QUIRK_BROKEN_HISPD_MODE" is introduced.
For more details about this refer to the Xilinx answer-recor #59999
https://www.xilinx.com/support/answers/59999.html
This commit:
- doesn't set HISPD bit on the host-conroller
- reflects this fact within the host-controller capabilities
Upon this the layer above (mmc-driver) can setup the card correctly.
Otherwise the MMC card will be switched into high-speed mode and causes
possible timing violation on the host-controller side.

Enable uart overrun feature which allows to benefits of uart
FIFO usage.
Previously overrun management was disabled, this has to effect
to bypassed the uart FIFO usage even if FIFO was enabled.
In particular configuration, for example when video console is
enabled, copy/pasting a long command line in console results in
corruption. This is due to the fact that a lot of time is consumed
in flushing the cache during frame buffer update, so uart chars are
not read fast enough.
By using uart FIFO and managing overrun, long command line can by
copy/paste in console without being corrupted.

when one wants to set PHY ADDR on a iMX board (FEC + driver model).
This shall be changed to CONFIG_FEC_MXC_PHYADDR, as only when we do have

As a side effect, when CONFIG_FEC_MXC_PHYADDR is not set, we scan PHY bus
