Subject: gs101 oriole: peripheral block 1 (peric1) and i2c12 support

Hi,

This patch series implements support for the 2nd connectivity
peripheral block on gs101.
This block contains an additional 6 USI, 1 I3C and 1 PWM
interfaces/busses.

i2cdetect shows all expected devices on the one i2c bus that this patch
series enables.
Everything that's in scope in this series works also without the
clk_ignore_unused kernel command line argument.

While working on this, I noticed the existing peric0 support for gs101
has a couple issues. That explains why there are differences compared
to it and a separate patch series will be sent to fix up peric0
support.

Cheers,
Andre'

Subject: [PATCH 3/9] clk: samsung: gs101: add support for cmu_peric1

CMU_PERIC1 is the clock management unit used for the peric1 block which
is used for additional USI, I3C and PWM interfaces/busses. Add support
for muxes, dividers and gates of cmu_peric1, except for
CLK_GOUT_PERIC1_IP which isn't well described in the datasheet and
which downstream also ignores (similar to cmu_peric0).

Two clocks have been marked as CLK_IS_CRITICAL for the following
reason:
* disabling them makes it impossible to access any peric1
registers, (including those two registers).
* disabling gout_peric1_lhm_axi_p_peric1_i_clk sometimes has the
additional effect of making the whole system unresponsive.

The clocks marked as CLK_IGNORE_UNUSED need to be kept on until we have
updated the respective drivers for the following reasons:
* gout_peric1_gpio_peric1_pclk is required by the pinctrl
configuration. With this clock disabled, reconfiguring the pins
(for USI/I2C, USI/UART) will hang during register access.
Since pingctrl-samsung doesn't support a clock at the moment, we
just keep the kernel from disabling it at boot, until we have an
update for samsung-pinctrl, at which point we'll drop the flag.
* gout_peric1_sysreg_peric1_pclk needs to be hooked up to
sysreg_peric1 in DT which will be done in a followup-patch, at
which point we'll drop the special treatment from here. We're
adding the flag temporarily here so as to not break the boot (due
to pclk otherwise getting disabled).

Looks like PATCH [00/xx] is missing in the subject.

I remember Krzysztof asked me to put pinctrl-0 first in my recent
patches. Not sure how important it is, just saying. Other than that,
LGTM:

But there are no bus clients declared here? A bit of explanation about
how this bus is being currently used would be nice to have (in commit
message); e.g. maybe it's used in user space somehow, etc. Because
otherwise it doesn't have much sense to enable the bus with no users.

As Sam said, you could be a bit more verbose on what those USB devices
are on the bus as they aren't enabled in this series. But apart from
that

No, it's 81 characters. While I know it's not a hard rule in this case,
there are other cases in this file where the line was split in the same

As per the commit message, there are devices, but:
* most or all don't have an upstream driver at this stage
* it does make sense to enable the bus, as enabling it allows working on
the drivers for the devices that are attached to this bus

I didn't add it, because at the time &sysreg_peric1 was added, the clock
macro CLK_GOUT_PERIC1_SYSREG_PERIC1_PCLK didn't exist and &sysreg_peric1
wasn't in use until this series here anyway.
If this patch here gets backported to some older kernel due to the Fixes: tag,
without the whole peric1 series, it wouldn't build. Therefore I left it out.

Should it still be added?

Clk patches don't have fixes tag, so Fixes for this alone would be
confusing.

In patch #3 I'm hooking up all the clocks to Linux. If I don't CLK_IGNORE_UNUSED
for the 'sysreg' pclk in patch #3, then it'll hang on loading drivers that
require sysreg access (because Linux disabled the clock).

I can not change patch #8 to come between 2 and 3 either, because at that stage
neither the clock nor the DT node reference &cmu_peric1 actually exist, and the
clock and can't be claimed by sysreg.

Since we can not mix DT and driver changes in the same commit, I can not merge
patches #3 and #4 and #8 either.

I had to do it this way so that the platform always boots for every commit to keep
things bisectable.

Alternatively, I could merge patches #4 and #8 (but that seems wrong to me), or
drop patches #7, #8 and #9 from this series and apply it later in the -rc phase?


Is there a better way that you have in mind that we're missing, that keeps things
atomic and bootable/bisectable?

Andre'

Then add clk_ignore_unused to cmdline. That's anyway recommended for
development platforms without full clock and pd description
(pd_ignore_unused). Not mentioning that we might default to
clk_ignore_unused at some point soon.

At the point of me applying this patch, there will be no DTS node
either. This ordering fixes nothing.

But it is not bisectable - you did not fix anything. You can try by
yourself:
# git checkout drivers
# git am patch #1, #2, #3 and #9
# git checkout dt
# git am patch #4, #5, #6, #7, #8

and now try to bisect it. You will have the same problems you try to
avoid. So what is solved by this ordering? Nothing.

Probably the mistake was done in the way how you upstream things: adding
sysreg syscon without its clocks.

Additionally:
1. Disabling unused clocks is current OS policy, so why the policy
should affect DTS and driver ordering?
2. This is platform did not receive a release kernel, so glitches are okay.

For this case #9 must be squashed with #3. #4 with #9.

Hi, Andre',

I played with SPI and noticed that we have to propagate some clock rates
to parents here. If you don't play with all the peripherals from the
block you can't know what to propagate. So I think it's fine to not
handle this topic right now. I'll come with a patch on top of yours when
I finish the SPI validation. The patch is looking fine. I'll finish
reviewing the series after v2 is out.

Cheers,
ta
