Add support for PERIC0 clocks. Use them for USI in serial and I2C
configurations. Tested the serial at different baudrates (115200,
1M, 3M) and the I2C with an at24 eeprom, all went fine.
Apart of the DT and defconfig changes, the patch set spans through the tty
and clk subsystems. The expectation is that Krzysztof will apply the whole
series through the Samsung SoC tree. If the tty and clk subsystem
maintainers can give an acked-by or reviewed-by on the relevant patches
that would be most appreciated!
Thanks!
ta
changes in v2:
- gs101 serial - infer the reg-io-width from the compatible as the entire
PERIC block allows just 32-bit register accesses.
- identify the critical clocks from PERIC0 and mark them accordingly
(if disabled these clocks hang the system even if their parents are
still enabled).
- update dtsi and use USI's gate clocks instead of the dividers clocks
- move hsi2c_8 cells and pinctrls into dtsi
- address Sam's cosmetic changes in the device tree files
- drop defconfig patches (savedefconfig output & at24 eeprom enablement)
- collect Acked-by and Reviewed-by tags
- changes log in each patch as well, in the comments section under

- fix comments as per Sam's suggestion and collect his R-b tag
- Rob's suggestion of renaming the clock-names to just "bus" and "ip"
was not implemented as I felt it affects readability in the driver
and consistency with other exynos clock drivers. I will happily update
the names in the -rc phase if someone else has a stronger opinion than
mine.

GS101's Connectivity Peripheral blocks (peric0/1 blocks) which
include the I3C and USI (I2C, SPI, UART) only allow 32-bit
register accesses. If using 8-bit register accesses, a SError
Interrupt is raised causing the system unusable.
Instead of specifying the reg-io-width = 4 everywhere, for each node,
the requirement should be deduced from the compatible.
Prepare the samsung tty driver to allow IO types different than
UPIO_MEM. ``struct uart_port::iotype`` is an unsigned char where all
its 8 bits are exposed to uapi. We can't make NULL checks on it to
verify if it's set, thus always set it from the driver's data.

Infer UPIO_MEM32 iotype from the "google,gs101-uart" compatible.
Update the uart info name to be GS101 specific in order to
differentiate from the other exynos platforms. All the other settings
are not changed.
exynos_fifoszdt_serial_drv_data was replaced by gs101_serial_drv_data
because the iotype restriction is gs101 specific and there was no other
user of exynos_fifoszdt_serial_drv_data.

CLK_GOUT_PERIC0_IP (not enough info in the datasheet).
Few clocks are marked as critical because when either of them is
disabled, the system hangs even if their clock parents are enabled.

Get rid of the dummy clock and start using the cmu_peric0 clocks
for the usi_uart and serial_0 nodes.
Tested the serial at 115200, 1000000 and 3000000 baudrates,
everthing went fine.

USI8 I2C is used to communicate with an eeprom found on the battery
connector. Define USI8 in I2C configuration.
USI8 CONFIG register comes with a 0x0 reset value, meaning that USI8
doesn't have a default protocol (I2C, SPI, UART) at reset. Thus the
selection of the protocol is intentionally left for the board dts file.

Remove the reg-io-width property in order to comply with the bindings.
The entire bus (PERIC) on which the GS101 serial resides only allows
32-bit register accesses. The reg-io-width dt property is disallowed
for the "google,gs101-uart" compatible and instead the iotype is
inferred from the compatible.

Given the clock-names, shouldn't the clock indices be the other way around? Also see below.

Here, pclk == CLK_GOUT_PERIC0_CLK_PERIC0_USI8_USI_CLK (which is correct, I believe), whereas
above pclk == CLK_GOUT_PERIC0_PERIC0_TOP0_IPCLK_7

You're right, they should have been the other way around! Didn't make
any difference at testing because the usi driver uses
clk_bulk_prepare_enable(), what matters is the order of clocks in the
i2c node, and those are fine.

Indeed, I'll reverse the order for the USI clocks and do some more
testing. Thanks!

These ones look sane to me. The clocks on the USI parent as well. USI
datasheet says that IPCLK is the protocol operating clock and PCLK the
APB clock. In the serial driver clk_uart_baud0 (IPCLK) is used as the
operating clock, all fine here.
Tell if you still think otherwise. Thanks!

FYI, I reversed the order of the USI clocks, tested again with the
eeprom at 100 KHz and 10KHz, everything went fine. I'll wait for some
other feedback and probably submit a v3 next week.

Is there a reason you are trying to add unused memory spaces to this
structure for no valid reason? I don't think you could have picked a
more incorrect place in there to add this :)
Please fix.

If you do, spend some time with the tool, pahole, and see if that's
really the best place for it or not. Might be, might not be, but you
should verify it please.

Thanks!
I played with pahole a bit. For arm32 this struct is not as bad defined
as for arm64, all members fit in the same cacheline. There are some
holes though and 2 cachelines for arm64 where this struct needs some
love. The best and minimum invasive change for my iotype member would be
to put it before the "has_divslot" member, as the has_divslot bitfield
will be combined with the previous field.
But I think the entire struct has to be reworked and the driver
butchered a bit so that we get to a better memory footprint and a single
cacheline. I volunteer to do this in a separate patch set so that we
don't block this series. I think the final struct can look as following:
struct s3c24xx_uart_info {
const char * name; /* 0 8 */
enum s3c24xx_port_type type; /* 8 4 */
unsigned int port_type; /* 12 4 */
unsigned int fifosize; /* 16 4 */
u32 rx_fifomask; /* 20 4 */
u32 rx_fifoshift; /* 24 4 */
u32 rx_fifofull; /* 28 4 */
u32 tx_fifomask; /* 32 4 */
u32 tx_fifoshift; /* 36 4 */
u32 tx_fifofull; /* 40 4 */
u32 clksel_mask; /* 44 4 */
u32 clksel_shift; /* 48 4 */
u32 ucon_mask; /* 52 4 */
u8 def_clk_sel; /* 56 1 */
u8 num_clks; /* 57 1 */
u8 iotype; /* 58 1 */
u8 has_divslot:1; /* 59: 0 1 */
/* size: 64, cachelines: 1, members: 17 */
/* padding: 4 */
/* bit_padding: 7 bits */
};
This looks a lot better than what we have now:
/* size: 120, cachelines: 2, members: 17 */
/* sum members: 105, holes: 2, sum holes: 8 */
/* sum bitfield members: 1 bits (0 bytes) */
/* padding: 4 */
/* bit_padding: 23 bits */
/* last cacheline: 56 bytes */
I'll put iotype before has_divslot and then follow up with a patch set
to clean the driver. Cheers,
ta

It would be good to get Krzysztof and Robs view on whether they agree
with the above rationale or whether they would still like to see the
names updated.
Personally I like the consistency, grepability and the fact the
current name encodes whether it is a gate, divider into the name.
Seeing 'sss' or 'ip' as a clock name in the driver code doesn't tell
you a lot without having to then cross reference with the dts.
Is there some rationale and/or benefit behind having the shorter
names? The only thing I could think of is trying to partially re-use
this file on future SoCs like gs201 which might be clocked
differently, but then these exynos clock drivers seem to be SoC
specific anyway.
Anyways apart from that:

That's a nice addition to avoid folks shooting themselves in the foot

The point of -names is to identify one entry from another in the list.
Having the name of the block is just redundant.
I like consistency, but not when it's a pattern we don't want.

I miss the point why clock-names cannot be fixed now. This is the name
of property, not the input clock name.

They can be fixed now. I've just aired the fixes at:
https://lore.kernel.org/linux-arm-kernel/[email protected]/
Preparing v3 for this patch set to include the updated names here too.

I think I was not that clear enough. I did not get your current patchset
- so PERIC0 clock controller - cannot use new naming.

Ok, I understand that the fixes from
https://lore.kernel.org/linux-arm-kernel/[email protected]/
are NACK-ed and I shall use the full clock-names in this patch set as
well, thus "dout_cmu_peric0_bus", and "dout_cmu_peric0_ip". I don't mind
changing them back, will send a v4 using the full clock names.
Out of curiosity, why can't we change the names? All gs101 patches are
for v6.8, thus they haven't made a release yet. We still have the -rc
phase where we can fix things.
Thanks for the guidance.

They are not rejected, it is just independent thing. At least looks like
independent.

We can change. I would not bother that much with doing that, because I
sent already them to arm-soc. That means I need to consider this as
fixes and I just did not want to deal with it.
The question is quite different for a new clock controller - peric0.
What parts of driver readability is affected by using "bus" name?

Krzysztof

The datasheet is not so verbose, but as I understand, CMU_MISC and
CMU_PERIC0 are clock domains of the same clock controller, thus I think
they should be treated the same. We should either get rid of the name of
the block in the clock names or keep it, but be consistent across all
the clock domains.

As Peter pointed out, if keeping the shorter names, one would have to
cross reference with the device tree in order to determine which clock
is used, its type, whether it's a gate or a divider. Whereas if we keep
the full name, one can see what's the clock about with a glance. The
full name coincides with the clock names that are defined in the clock
driver, thus one can grep for the full name from the device tree and hit
the clock definition from the clock driver.
The cons of keeping the full name is that keeping the name of the block
in the DT's clock name is just redundant. Rob was clear and said that
including the block name in the -names is a pattern we don't want.
In what concerns my personal preference, I like the full name. At the
same time, I see Rob's point, and if that turns out to be a rule, let's
respect it. So I'm fine with both, but let's be consistent across the
driver and have the same clock name scheme for all the clock domains,
otherwise it will just look weird.
