v5 cover Add QSPI and QUPv3 DT nodes for SC7280 SoC

Changes in V5:
- As per Matthias' comments, I've split the patches as below:
1. Add QSPI node
2. Configure SPI-NOR FLASH for sc7280-idp
3. Add QUPv3 wrapper_0 nodes
4. Update QUPv3 UART5 DT node
5. Configure debug uart for sc7280-idp
6. Configure uart7 to support bluetooth on sc7280-idp
7. Add QUPv3 wrapper_1 nodes

Changes in V4:
- As per Stephen's comment updated spi-max-frequency to 37.5MHz, moved qspi_opp_table from /soc to / (root).
- As per Bjorn's comment, added QUP Wrapper_0 nodes
as separate patch and debug-uart node as separate patch.
- Dropped interconnect votes for wrapper_0 and wrapper_1 node
- Corrected QUP Wrapper_1 SE node's pin control functions like below QUP Wrapper_0: SE0-SE7 uses qup00 - qup07 pin-cntrl functions. QUP Wrapper_1: SE0-SE7 uses qup10 - qup17 pin-cntrl functions.

Changes in V3:
- Broken the huge V2 patch into 3 smaller patches.
1. QSPI DT nodes
2. QUP wrapper_0 DT nodes
3. QUP wrapper_1 DT nodes

Changes in V2:
- As per Doug's comments removed pinmux/pinconf subnodes.
- As per Doug's comments split of SPI, UART nodes has been done.
- Moved QSPI node before aps_smmu as per the order.

For now I am keeping qspi_opp_table and qup_opp_table outside the SoC and posting V6. I will continue the discussion with DT folks and once concluded I will update as required.

Do you have a link to that discussion so that people can follow along or chime in?

Shouldn't the OPP table live outside of /soc, analogous to the discussion about the QSPI OPP table (https://lkml.org/lkml/2021/7/19/3063)?

nit: the general convention seems to be 'clocks' followed by 'clock-names'. Applicable to all nodes if you decide to change it.

What is the story behind 'qup_spiN_cs' and 'qup_spiN_cs_gpio'? Both configure the CS pin with a different function:

  qup_spi0_cs: qup-spi0-cs {
  	pins = "gpio3";
  	function = "qup00";
  };

  qup_spi0_cs_gpio: qup-spi0-cs_gpio {
  	pins = "gpio3";
  	function = "gpio";
  };

Wait, why does uart5 use the pins of qup13? Is see this is 'fixed' by '[4/7] arm64: dts: sc7280: Update QUPv3 UART5 DT node' but I'm still surprised ...

Doesn't 'fixing' this break devices that are currently using 'uart5'? It seems those devices would need to change from 'uart5' to 'uart11'.

Apparently the above configuration is bogus. I checked the schematic of the IDP which uses uart5, the debug UART is on pins 22 and 23, aka qup05. It seems uart5 works in spite of the bogus pinconf because the default for the pins is their QUP function.

Shouldn't the OPP table live outside of /soc, analogous to the discussion about the QSPI OPP table (https://lkml.org/lkml/2021/7/19/3063)?

nit: the general convention seems to be 'clocks' followed by 'clock-names'. Applicable to all nodes if you decide to change it.

What is the story behind 'qup_spiN_cs' and 'qup_spiN_cs_gpio'? Both configure the CS pin with a different function:

As per discussion here [1], we have split like this.

Wait, why does uart5 use the pins of qup13? Is see this is 'fixed' by '[4/7] arm64: dts: sc7280: Update QUPv3 UART5 DT node' but I'm still surprised ...

Doesn't 'fixing' this break devices that are currently using 'uart5'? It seems those devices would need to change from 'uart5' to 'uart11'.

What is the story behind 'qup_spiN_cs' and 'qup_spiN_cs_gpio'? Both configure
the CS pin with a different function:

As per discussion here [1], we have split like this.

[1] https://lore.kernel.org/patchwork/patch/1393353/#1591826

IIUC that's only about having separate configs for each pin, instead of groups like 'qup-spi0-default'. What you are doing above with 'qup_spi0_cs' and 'qup_spi0_cs_gpio' is to configure the same pin (GPIO 3) both as SPI chip select and as GPIO. Which one is it?

I imagine we want to have both pinctrl definitions to allow a board to configure the pin either as SPI CS or GPIO. However it should be only one of the two at a time, and the SoC .dtsi should provide a reasonable default, which probably is SPI CS.

Maybe I'm missing something, if so please provide details on why it is necessary to have this config.

Not a full review of your patch (I think Matthias has already looked in a bunch of detail), but can I also request that you add i2c and spi aliases in your next spin (I think you have to spin this anyway, right?) Add these under the "aliases" mode before the mmc ones (to keep sort order good):

i2c0 = &i2c0;
i2c1 = &i2c1;
i2c2 = &i2c2;
i2c3 = &i2c3;
i2c4 = &i2c4;

i2c12 = &i2c12;
i2c13 = &i2c13;
i2c14 = &i2c14;
i2c15 = &i2c15;

...and these after:

spi0 = &spi0;
spi1 = &spi1;
spi2 = &spi2;
spi3 = &spi3;
spi4 = &spi4;
spi5 = &spi5;
spi6 = &spi6;

spi11 = &spi11;
spi12 = &spi12;
spi13 = &spi13;
spi14 = &spi14;
spi15 = &spi15;

The "Quad SPI" doesn't get an alias, but that's OK. It doesn't have a well-defined number in the manual and it's fine to have it be auto-assigned. It's really just confusing when there's something with a well-defined number in the manual and it's a _different_ one in the logs. ;-)
