2024-01-03clk: starfive: Add flags argument to JH71X0__MUX macroEmil Renner Berthing
This flag is needed to add the CLK_SET_RATE_PARENT flag on the gmac_tx clock on the JH7100, which in turn is needed by the dwmac-starfive driver to set the clock properly for 1000, 100 and 10 Mbps links. This change was mostly made using coccinelle: @ match @ expression idx, name, nparents; @@ JH71X0__MUX( -idx, name, nparents, +idx, name, 0, nparents, ...)

2023-04-17clk: starfive: Delete the redundant dev_set_drvdata() in JH7110 clock driversHal Feng
The dev_set_drvdata() is no longer needed after we used a wrapper struct to get the data in auxiliary driver.

2023-04-13clk: starfive: Avoid casting iomem pointersStephen Boyd
Let's use a wrapper struct for the auxiliary_device made in jh7110_reset_controller_register() so that we can stop casting iomem pointers. The casts trip up tools like sparse, and make for some awkward casts that are largely unnecessary. While we're here, change the allocation from devm and actually free the auxiliary_device memory in the release function. This avoids any use after free problems where the parent device driver is unbound from the device but the auxiliuary_device is still in use accessing devm freed memory.
