[PATCH 2/2] mmc: sdhci-acpi: AMDI0040: Allow changing HS200/HS400 driver strength

2020-09-28 Thread Raul E Rangel
This change will allow platform designers better control over signal integrity by allowing them to tune the HS200 and HS400 driver strengths. The driver strength was previously hard coded to A to solve boot problems with certain platforms. This driver strength does not universally apply to all pla
