This is a companion to u-boot,noautostart. If one has a single
watchdog device that one does want to have auto-started, but several
others that one doesn't, the only way currently is to set the
CONFIG_WATCHDOG_AUTOSTART and then use the opt-out for the majority.
The main motivation for this is to add an autostarted watchdog device
to the sandbox (to test a fix) without having to set AUTOSTART in
sandbox_defconfig and add the noautostart property to the existing
devices. But it's also nice for symmetry, and the logic in
init_watchdog_dev() becomes simpler to read because we avoid all the
negations.

Clock patches for 2023.01
This contains various fixes (some long overdue) for the next release.
|
|
Beside some rather unexciting sync of the DTs from the kernel tree, and
some Kconfig cleanup, there are some improvements for the ARMv5 Allwinner
family, to support boards with the F1C200s (64MB DRAM) better. We will
get actual board support as soon as the DTs have passed the Linux review
process.
There is also support for the X96 Mate TV Box, featuring the H616 SoC and
a full 4GB of DRAM.
Also we found the secret to enable SPI booting on the H616 (pin PC5 must
be pulled to GND), so the SPI boot support patch is now good to go.
Passed the gitlab CI, plus briefly tested on Pine64-LTS, LicheePi Nano,
X96 Mate and OrangePi Zero.

In clk_clean_rate_cache, clk->rate should update the private clock
struct, in particular when CCF is activated, to save the cached
rate value.
When clk_get_parent_rate is called, the cached information
is read from pclk->rate, with pclk = clk_get_parent(clk).
As the cached is read from private clk data, the update should
be done also on it.

All functions getting and setting clock rate use ulong for rate, only
clk_get_parent_rate is an exception. Change the return value to match
other clock rate funcrions.
Most users directly assign the rate to unsigned long anyway, and the few
users that use u64 (not s64) multiply the rate so they may need the
extra bits for the result in their use case.

The original code set up the DDR clock to 48 MHz, not 50MHz as
requested, and did it in a way that didn't satisfy the Application
Notes in RK3399 TRM [1]. 2.9.2.B says:
PLL frequency range requirement
[...]
FOUTVCO: 800MHz to 3.2GHz
2.9.2.A :
PLL output frequency configuration
[...]
FOUTVCO = FREF / REFDIV * FBDIV
FOUTPOSTDIV = FOUTVCO / POSTDIV1 / POSTDIV2
FREF = 24 MHz
The original code gives FOUTVCO: 24MHz/1 * 12 = 288MHz < 800MHz
And the resulting FOUTPOSTDIV is 288MHz / 3 / 2 = 48MHz
but the requested frequency was 50MHz
Note:
2.7.2 Detail Register Description
PMUCRU_PPLL_CON0 says
fbdiv
Feedback Divide Value
Valid divider settings are:
[16, 3200] in integer mode
So .fbdiv = 12 wouldn't be right. But 2.9.2.C says:
PLL setting consideration
[...]
The following settings are valid for FBDIV:
DSMPD=1 (Integer Mode):
12,13,14,16-4095 (practical value is limited to 3200, 2400, or 1600
(FVCOMAX / FREFMIN))
[...]
So .fbdiv = 12 would be right.
In any case FOUTVCO is still wrong. I thank YouMin Chen for
confirmation and explanation.
Despite documentation, I don't seem to be able to reproduce a
practical problem with the wrong FOUTVCO. When I initially found it I
thought some problems with detecting the RAM capacity in my Rock Pi 4B
could be related to it and my patch seemed to help. But since I'm no
longer able to reproduce the issue, it works with or without this
patch. And meanwhile a patch[2] by Lee Jones and YouMin Chen addresses
this issue. Btw, shouldn't that be commited?
So this patches solves no visible problem. Yet, to prevent future
problems, I think it'd be best to stick to spec.
An alternative to this patch could be
{.refdiv = 1, .fbdiv = 75, .postdiv1 = 6, .postdiv2 = 6};
This would theoretically consume more power and yield less jitter,
according to 2.9.2.C :
PLL setting consideration
[...]
For lowest power operation, the minimum VCO and FREF frequencies
should be used. For minimum jitter operation, the highest VCO and
FREF frequencies should be used.
[...]
But I haven't tried it because I don't think it matters much. 50MHz
for DDR is only shortly used by TPL at RAM init. Normal operation is
at 800MHz. Maybe it's better to use less power until later when more
complex software can control batteries or charging or whatever ?

The _err variant iterators use the simple iterators without suffix as
basis.
However, there is no user that uclass_next_device_err for iteration,
many users of uclass_first_device_err use it to get the first and
(assumed) only device of an uclass, and a couple that use
uclass_next_device_err to get the device following a known device in the
uclass list.
While there are some truly singleton device classes in which more than
one device cannot exist these are quite rare, and most classes can have
multiple devices even if it is not the case on the SoC's EVB.
In a later patch the simple iterators will be updated to not stop on
error and return next device instead. With this in many cases the code
that expects the first device or an error if it fails to probe may get
the next device instead. Use the _check iterators as the basis of _err
iterators to preserve the old behavior.

Although the function names superficially match the return value from

In the following patch the semantic of

There is a number of users that use uclass_first_device to access the
first and (assumed) only device in uclass.
Some check the return value of uclass_first_device and also that a
device was returned which is exactly what uclass_first_device_err does.
Some are not checking that a device was returned and can potentially
crash if no device exists in the uclass. Finally there is one that
returns NULL on error either way.
Convert all of these to use uclass_first_device_err instead, the return
value will be removed from uclass_first_device in a later patch.

A recent change to regmap breaks building of phycore-rk3288 for me. The
difference is only a few bytes. Somehow CI seems to pass, even though it
fails when I run docker locally. But it prevents me from sending any more
pull requests.
In any case this board is clearly near the limit. We could revert the
offending change, but it is needed for sandbox tests.
Instead, add a way to drop the range checks in SPL, since they end up
doing nothing if everything is working as expected.
This makes phycore-rk3288 build again for me and reduces the size of SPL

When host issues "fastboot reboot fastboot", it's expected that the
board drops the USB connection before resetting.
On some boards, such as Khadas VIM3L and SEI610, this is not the case.
We observe the following error:
$ fastboot reboot fastboot
Rebooting into fastboot OKAY [ 0.004s]
fastboot: error: Failed to boot into userspace fastboot; one or more components might be unbootable.
This does not happen when we use the RST button on the board.
It can be reproduced in linux with:
# echo b > /proc/sysrq-trigger
In this case, we hit a undefined hardware behavior, where D+ and D-
are in an unknown state. Therefore the host can't detect usb
disconnection.
Make sure we always call usb_gadget_release() when a "fastboot reboot"
command is issued.
Note: usb_gadget_release() should be called before g_dnl_unregister()
because g_dnl_unregister() triggers a complete() call on each
endpoint (thus calling do_reset()).
