Sascha Hauer 3d705d14fe mmc: implement Driver Stage Register handling ... Some eMMC and SD cards implement a DSR register that allows to tune raise/fall times and drive strength of the CMD and DATA outputs. The values to use depend on the card in use and the host. It might be needed to reduce the drive strength to prevent voltage peaks above the host's specification. Implement a 'dsr' devicetree property that allows to specify the value to set the DSR to. For non-dt setups the new members of mmc_host can be set by board code. This patch was initially authored by Sascha Hauer. It contains improvements authored by Markus Niebel and Uwe Kleine-König.
