In some cases (such as a boot from SPI) the bootloader or the ROM code may
leave a bias pull-down on the mmc pins. If so the MMC will fail during the
initialisation.
Explicitly disabling the pinmux solves the problem.

In the pinmux of the mmc clk_gate nodes, we define 2 subnodes. One for
the function definition, the other for the bias. This is not necessary
since we can define the function and the bias in the same subnode.

The AP6212 module used on the VIM basic has an ID clash with another

The Tanix TX3 Mini is a TV box based on the Amlogic S905W chipset.
There are two variants:
- 1 GiB or 2 GiB of DDR3 memory
- 8 GB or 16 GB eMMC flash
Both variants come with:
- 802.11 b/g/n wifi (Silicon Valley Microelectronics SSV6051, does not
support Bluetooth)
- an LED 7 segment display with an FD628 controller
- HDMI and AV (CVBS) output
- 2x USB (utilizing both USB ports provided by the SoC)
- micro SD card slot
- serial console (uart_AO) has to be soldered after opening the case
The board seems to be very similar to the P23x and Q20x reference
boards, which is why it includes meson-gx-p23x-q20x.dtsi:
- eMMC reset routed to BOOT_9
- the SDIO wifi chip's reset line is routed to GPIOX_6 and the reference
clock is 32.768KHz on PWM_E
- SD card detection is routed to CARD_6
- vqmmc of all MMC controllers is hard-wired to 1.8V (VDDIO_BOOT)
- uart_AO can be accessed after opening the case and soldering RX, TX
and GND lines onto the exposed solder points (marked with RX, TX and
GND)
