Description

media: fix firefly-rk3399 mini-pcie slot.

Problem description: The 3G/4G module is not available on the firefly-rk3399.

  1. According to the schematic, the "MINI PCIE" on the firefly-rk3399 only has USB2 functionality. firefly-rk3399-mini-pcie-slot
  2. Comparing with the official kernel device tree, it is found that the vcc3v3-3g-regulator power supply node is missing.
  3. However, the pins used by this node conflict with the leds node referenced in the kernel device tree for roc-rk3399-pc. This node is redundant in firefly-rk3399, so it is defined as "node deletion".

Summary of modifications:

  1. Added vcc3v3-3g-regulator power supply node.
  2. Defined node deletion.
