2023-03-28clk: xilinx: Convert to platform remove callback returning voidUwe Kleine-König2-8/+4
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.

2023-03-28clk: xilinx: Drop if block with always false conditionUwe Kleine-König1-2/+0
xvcu_remove() is only called for a device after after xvcu_probe() completed successfully. In that case dev_set_drvdata() was called for that device with a non-NULL parameter, so platform_get_drvdata() won't return NULL and the if condition is never true. Drop the if, preparing a conversion to make platform driver's remove callback return void.

2023-03-27clocking-wizard: Support higher frequency accuracyShubhrajyoti Datta1-24/+204
Change the multipliers and divisors to support a higher frequency accuracy if there is only one output. Currently only O is changed now we are changing M, D and O. For multiple output case the earlier behavior is retained.

2022-10-17clk: xilinx: Drop duplicate depends on COMMON_CLKStephen Boyd1-2/+2
This entire Kconfig file is only included within the if COMMON_CLK section of the drivers/clk/Kconfig file. That makes the depends on COMMON_CLK here redundant. Remove it.

2022-10-03clk: clocking-wizard: Depend on HAS_IOMEMStephen Boyd1-0/+1
This driver uses devm_platform_ioremap_resource() and thus depends on HAS_IOMEM. Add the Kconfig dependency to avoid build issues.

The 5.2 the reconfig is triggered by writing 7 followed by 2 to the reconfig reg. Add the same. Also 6.0 is backward compatible so it should be fine.

2021-02-08clk: xilinx: move xlnx_vcu clock driver from socMichael Tretter3-0/+764
The xlnx_vcu driver is actually a clock controller driver which provides clocks that can be used by a driver for the encoder/decoder units. There is no reason to keep this driver in soc. Move the driver to clk. NOTE: The register mapping actually contains registers for AXI performance monitoring, but these are not used by the driver.
