      ARM: dts: am57xx-idk: Select pull down for mmc1_clk line in default mode · 18aa0f4b
      Kishon Vijay Abraham I 提交于
      During a short period when the bus voltage is switched from 3.3v to 1.8v,
      (to enumerate UHS mode), the mmc module is disabled and the mmc IO lines
      are kept in a state according to the programmed pad mux pull type.
      
      According to 4.2.4.2 Timing to Switch Signal Voltage in "SD Specifications
      Part 1 Physical Layer Specification Version 5.00 February 22, 2016", the
      host should hold CLK low for at least 5ms.
      
      In order to keep the card line low during voltage switch, the pad mux of
      mmc1_clk line should be configured to pull down.
      
      This is specific to am57xx-idk (and not all dra72/dra74 based boards)
      since mmc1_clk line in am57xx-idk is not connected to an external
      pullup.
      
      While at that change the order of header files in am571x-idk.dts and
      am572x-idk.dts so that the modified pinctrl values in am57xx-idk-common
      could take effect.

      - Dual 1Gbps Ethernet
      - HDMI,
      - PRU-ICSS
      - uSD
      - 16GB eMMC
      - CAN
      - RS-485
      - PCIe
      - USB3.0
      - Video Input Port
      - Industrial IO port and expansion connector

      This patch creates a common dtsi file that will provide a common board
      dtsi file to define the nodes that are common to AM57xx (including the
      upcoming AM5718) IDK boards.
      
      Initial support is only for basic peripherals
