[PATCH v1 1/5] dt-bindings: dmaengine: qcom: gpi: Add additional arg to dma-cell property

[PATCH v1 1/5] dt-bindings: dmaengine: qcom: gpi: Add additional arg to dma-cell property
Posted by Jyothi Kumar Seerapu 1 month, 1 week ago 
When high performance with multiple i2c messages in a single transfer
is required, employ Block Event Interrupt (BEI) to trigger interrupts
after specific messages transfer and the last message transfer,
thereby reducing interrupts.

For each i2c message transfer, a series of Transfer Request Elements(TREs)
must be programmed, including config tre for frequency configuration,
go tre for holding i2c address and dma tre for holding dma buffer address,
length as per the hardware programming guide. For transfer using BEI,
multiple I2C messages may necessitate the preparation of config, go,
and tx DMA TREs. However, a channel TRE size of 64 is often insufficient,
potentially leading to failures due to inadequate memory space.

Add additional argument to dma-cell property for channel TRE size.
With this, adjust the channel TRE size via the device tree.
The default size is 64, but clients can modify this value based on
their specific requirements.

This is a firmware /software property, why should this be in hardware

Hi, Yes, this is a software property and added as a 4th argument of 
"dma-cells" for configuring channel tre size, so added the description 
for dma-cells.
In V2 patch, i reverted the changes and will handle with the default 
channel tre size present in the GPI driver.

This is a software property and here trying to add channel tre size as a 
4th argument of dma-cells property.

In V2, i have reverted the DT and binding changes related to adding new 
argument for dma-cells property and used GPI driver defined value.

No such property 'dma-cell'

Thanks for pointing it out, yeah it should be 'dma-cells'.

Please kindly test the patches before you sent them. Upstream is not a

The base for the series is generally the latest rc1. A different dependency

If you already ran 'make dt_binding_check' and didn't see the above

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Thanks, i followed the instructions and resolved errors which observed 
with 'make dt_binding_check'.
But in V2 patch, i have reverted the DT and binding changes related to 
adding new argument for dma-cells property and instead used existing 
value for channel TRE size in GPI driver.
