2023-09-27mmc: starfive: Change tuning implementationWilliam Qiu
Before, we used syscon to achieve tuning, but the actual measurement showed little effect, so the tuning implementation was modified here, and it was realized by reading and writing the UHS_REG_EXT register.

2023-06-12mmc: dw_mmc: Make dw_mci_pltfm_remove() return voidUwe Kleine-König
dw_mci_pltfm_remove() returned zero unconditionally. Make it return void instead which makes its semantics a bit clearer. Convert the drivers that use this function as .remove() callback to .remove_new() which has the right prototype. This helps getting rid of the platform_driver's remove callback that returns an int (which is error prone). The other users didn't check the return value anyhow.
