Currently this driver is used by VEXPRESS platform which doesn't support Driver Model. ARM_PL180_MMCI IP is embedded on STM32F4 and F7 platforms. In order to add SD support on these 2 STM32 family SoCs, the following reworks are needed: _ update arm_pl180_mmci_init() prototype to make this driver working with DM and none DM platforms _ addapt driver to driver model _ add bus_width device tree support _ add clock support _ add .get_cd callback support
This series has been tested internally on both STM32F4 and STM32F7 SoCs family. Future SD support for these 2 platforms will be added soon.
v2: _ add defines for clock min and max value in patch 2 _ remove useless return in bus_width switch case in patch 3
