Ticket Name: DRA756: EMMC linux driver issue

Query Text:
Part Number: DRA756 Hi. sdk: PROCESSOR_SDK_VISION_03_05_00_00 For the same software, only the SOC of the two boards is different. One uses tda2s and the other uses dra756. Tda2s can use EMMC ddr50 mode.while dra756 cannot use ddr50 mode,Dra756 can use EMMC HS mode dts: &mmc2 { status = "okay"; vmmc-supply = <&evm_3v3_sw>; bus-width = <8>; max-frequency = <192000000>; pinctrl-names = "default", "hs", "ddr_1_8v-rev11", "ddr_1_8v","ddr50"; pinctrl-0 = <&mmc2_pins_default>; pinctrl-1 = <&mmc2_pins_hs>; pinctrl-2 = <&mmc2_pins_ddr_1_8v &mmc2_iodelay_ddr_1_8v_rev11_conf>; pinctrl-3 = <&mmc2_pins_ddr_1_8v &mmc2_iodelay_ddr_1_8v_rev20_conf>; pinctrl-4 = <&mmc2_pins_hs200_1_8v &mmc2_iodelay_hs200_1_8v_rev11_conf>; pinctrl-5 = <&mmc2_pins_hs200_1_8v &mmc2_iodelay_hs200_1_8v_rev20_conf>; }; dr756 emmc ddr50 mode log: [ 1.072168] ldousb: disabling [ 1.073427] omap8250 4806a000.serial: failed to request DMA [ 1.074258] Waiting for root device PARTUUID=dda7f685-03...
