[PATCH V4 2/4] arm64: dts: sc7280: Add QUPv3 wrapper_0 nodes

From: Rajesh Patil <hidden>
Date: 2021-07-26 13:42:52 

From: Roja Rani Yarubandi <redacted>

Add QUPv3 wrapper_0 DT nodes for SC7280 SoC.

Signed-off-by: Roja Rani Yarubandi <redacted>

---
Changes in V4:
 - As per Bjorn's comment, added QUP Wrapper_0 nodes
   other than debug-uart node
 - Dropped interconnect votes for wrapper_0 node

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.

Changes in V4:
 - As per Bjorn's comment, added QUP Wrapper_0 nodes
   other than debug-uart node
 - Dropped interconnect votes for wrapper_0 node

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.

How the patches of this series are split strikes me as a bit odd. Supposedly
this patch adds the QUPv3 wrapper_0 DT nodes for the SC7280, however the
above is the pin configuration for the Bluetooth UART of the SC7280 IDP board.
I don't see a good reason why that should be part of this patch. It should be
a separate change whose subject indicates that it configures the Bluetooth UART
of the SC7280 IDP.

Without this conflation of SoC and board DT it would seem perfectly reasonable
to squash this patch and '[4/4] arm64: dts: sc7280: Add QUPv3 wrapper_1 nodes'
into a single one, they are essentially doing the same thing, I see no need to
have different patches for the wrapper 0 and 1 nodes.

How the patches of this series are split strikes me as a bit odd. 
Supposedly
this patch adds the QUPv3 wrapper_0 DT nodes for the SC7280, however 
the
above is the pin configuration for the Bluetooth UART of the SC7280 IDP 
board.
I don't see a good reason why that should be part of this patch. It 
should be
a separate change whose subject indicates that it configures the 
Bluetooth UART
of the SC7280 IDP.
Okay will split this up.

Without this conflation of SoC and board DT it would seem perfectly 
reasonable
to squash this patch and '[4/4] arm64: dts: sc7280: Add QUPv3 wrapper_1 
nodes'
into a single one, they are essentially doing the same thing, I see no 
need to
have different patches for the wrapper 0 and 1 nodes.
Previously when QUP wrapper 0 and wrapper 1 nodes were added in single 
patch, we faced some git issues as the patch was huge. Hence we split it 
up.

That bug tracker entry isn't public, this is what the comment says:

I suspect that diff is just having a hard time since your patch touches so
much stuff. Presumably you could make it happier if you broke your patch
into smaller changes. For instance:

One patch that adds the quad SPI. After all the quad SPI isn't really
related to the other QUP stuff. One patch that fixes up the existing
"uart5" and the QUP it's on to be how it's supposed to be. One patch
that adds all the new stuff.
If I understand correctly the problem wasn't that the QUP wrappers are
added in a single patch (which should be pretty straightforward to
review), but that the previous patch(es) do too many things at once.
Adding both QUP wrappers is conceptionally a single thing, the problem
is intermingling that with adding board specific Bluetooth nodes, board
flash nodes, pinconf for UART, etc

How the patches of this series are split strikes me as a bit odd.
Supposedly
this patch adds the QUPv3 wrapper_0 DT nodes for the SC7280, however the
above is the pin configuration for the Bluetooth UART of the SC7280 IDP
board.
I don't see a good reason why that should be part of this patch. It
should be
a separate change whose subject indicates that it configures the
Bluetooth UART
of the SC7280 IDP.
Okay will split this up.

Without this conflation of SoC and board DT it would seem perfectly
reasonable
to squash this patch and '[4/4] arm64: dts: sc7280: Add QUPv3 wrapper_1
nodes'
into a single one, they are essentially doing the same thing, I see no
need to
have different patches for the wrapper 0 and 1 nodes.
Previously when QUP wrapper 0 and wrapper 1 nodes were added in single
patch, we faced some git issues as the patch was huge. Hence we
split it up.

That bug tracker entry isn't public, this is what the comment says:
quoted
I suspect that diff is just having a hard time since your patch
touches so
much stuff. Presumably you could make it happier if you broke your
patch
into smaller changes. For instance:

One patch that adds the quad SPI. After all the quad SPI isn't really
related to the other QUP stuff. One patch that fixes up the existing
"uart5" and the QUP it's on to be how it's supposed to be. One patch
that adds all the new stuff.
If I understand correctly the problem wasn't that the QUP wrappers are
added in a single patch (which should be pretty straightforward to
review), but that the previous patch(es) do too many things at once.
Adding both QUP wrappers is conceptionally a single thing, the problem
is intermingling that with adding board specific Bluetooth nodes, board
flash nodes, pinconf for UART, etc
Even after splitting the patches as suggested(i.e., additions and
modifications separately), if I add qup wrapper0 and wrapper1 nodes in
single patch the git diff is getting messed up. pasted the diff for
reference

This configures the SPI flash of the SC7280 IDP board, which is neither

Most of the above should be added by patch '[2/4] arm64: dts: sc7280: Add QUPv3
wrapper_0 nodes'.

I have to say I dislike that the SoC DT file dictates which UART to use for
the serial console. Technically it could be any of them, right? uart5 is
used because that's what the IDP does, and the rest of the world is expected
to follow. Why not configure uart5 as "qcom,geni-uart" by default and
overwrite the compatible string and pinctrl in the board file? You could even
add 'qup-uartN-all' (or similar) pinconfigs to sc7280.dtsi, which would make
the changes in the board file trivial.

Based on the comments on v3 [1], I have added this as a separate patch
[1] https://lore.kernel.org/patchwork/patch/1441257/

I have to say I dislike that the SoC DT file dictates which UART to use 
for
the serial console. Technically it could be any of them, right? uart5 
is
used because that's what the IDP does, and the rest of the world is 
expected
to follow. Why not configure uart5 as "qcom,geni-uart" by default and
overwrite the compatible string and pinctrl in the board file? You 
could even
add 'qup-uartN-all' (or similar) pinconfigs to sc7280.dtsi, which would 
make
the changes in the board file trivial.
Okay, will make the compatible as "qcom,geni-uart" in SoC dt and later 
modify it in idp dts as "qcom,geni-debug-uart".

Thanks,
Rajesh

[PATCH V4 4/4] arm64: dts: sc7280: Add QUPv3 wrapper_1 nodes

From: Rajesh Patil <hidden>
Date: 2021-07-26 13:43:13 

From: Roja Rani Yarubandi <redacted>

Add QUPv3 wrapper_1 DT nodes for SC7280 SoC.

Signed-off-by: Roja Rani Yarubandi <redacted>
Signed-off-by: Rajesh Patil <redacted>
---
Changes in V4:
 - Dropped interconnect votes for 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.
