2024-10-17phy: Switch back to struct platform_driver::remove()Uwe Kleine-König1-1/+1
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/phy/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files.

2024-03-29phy: qualcomm: phy-qcom-eusb2-repeater: Add support for SMB2360Abel Vesa1-0/+17
The SMB2360 PMICs contain the same repeater as the PM8550B, but requiring different settings, so add dedicated compatible for SMB2360.

2024-02-07phy: qualcomm: eusb2-repeater: Rework init to drop redundant zero-out loopAbel Vesa1-104/+62
Instead of incrementing the base of the global reg fields, which renders the second instance of the repeater broken due to wrong offsets, use regmap with base and offset. As for zeroing out the rest of the tuning regs, avoid looping though the table and just use the table as is, as it is already zero initialized.

2023-09-21phy: qualcomm: phy-qcom-eusb2-repeater: Add tuning overridesKonrad Dybcio1-1/+16
There are devices in the wild, like the Sony Xperia 1 V that *require* different tuning than the base design for USB to work. Add support for overriding the necessary tuning values.

The vendor kernel zeroes out all tuning data outside the init sequence as part of initialization. Follow suit to avoid UB.

2023-09-21phy: qualcomm: phy-qcom-eusb2-repeater: Use regmap_fieldsKonrad Dybcio1-30/+61
Switch to regmap_fields, so that the values written into registers are sanitized by their explicit sizes and the different registers are structured in an iterable object to make external changes to the init sequence simpler.

2023-07-17phy: Explicitly include correct DT includesRob Herring1-1/+0
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.

2023-03-20phy: qualcomm: phy-qcom-eusb2-repeater: Convert to platform remove callback ↵Uwe Kleine-König1-5/+3
returning void 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 (mostly) ignored 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. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
