2023-07-19spi: rzv2m-csi: Improve data types, casting and alignmentFabrizio Castro1-23/+23
"unsigned int" is more appropriate than "int" for the members of "struct rzv2m_csi_priv". Using void* rather than u8* for txbuf and rxbuf allows for the removal of some type casting. Remove the unnecessary casting of "data" to "struct rzv2m_csi_priv*" in function "rzv2m_csi_irq_handler". Also, members "bytes_per_word" and "errors" introduce gaps in the structure. Adjust "struct rzv2m_csi_priv" and its members usage accordingly.

2023-07-17spi: rzv2m-csi: Rework CSI_CKS_MAX definitionFabrizio Castro1-1/+6
Clock "csiclk" gets divided by 2 * CSI_CLKSEL_CKS in order to generate the serial clock (output from master), with CSI_CLKSEL_CKS ranging from 0x1 (that means "csiclk" is divided by 2) to 0x3FFF ("csiclk" is divided by 32766). CSI_CKS_MAX is used for referring to the setting corresponding to the maximum frequency divider. Value 0x3FFF for CSI_CKS_MAX doesn't really means much to the reader without an explanation and a more readable definition. Add a comment with a meaningful description and also replace value 0x3FFF with the corresponding GENMASK, to make it very clear what the macro means.

2023-07-14spi: Explicitly include correct DT includesRob Herring43-48/+26
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-07-10spi: rzv2m-csi: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-07-10spi: sun6i: add quirk for dual and quad SPI modes supportMaksim Kiselev1-4/+25
New Allwinner's SPI controllers can support dual and quad SPI modes. To enable one of these modes, we should set the corresponding bit in the SUN6I_BURST_CTL_CNT_REG register. DRM (28 bits) for dual mode and Quad_EN (29 bits) for quad transmission.

We just sorted the entries and fields last release, so just out of a perverse sense of curiosity, I decided to see if we can keep things ordered for even just one release. The answer is "No. No we cannot". I suggest that all kernel developers will need weekly training sessions, involving a lot of Big Bird and Sesame Street. And at the yearly maintainer summit, we will all sing the alphabet song together. I doubt I will keep doing this. At some point "perverse sense of curiosity" turns into just a cold dark place filled with sadness and despair.
