Series arm64: meson-g12: enable support for SPIFC | expand


Neil Armstrong March 13, 2020, 9:07 a.m. UTC
On the Amlogic G12A and compatible SoCs, the SPI NOR pins are shared with the
eMMC data 4 to 7 pins, thus the DT needs some tweaking to allow setting
on the data 0 to 3 pins for the eMMC controller to enable the eMMC in the
same time as the SPIFC controller.

Since this lowers the performance of the eMMC, the SPIFC is left disabled
and intructions to enable the SPIFC controller as added like done for
the Khadas VIM2 SPIFC support.

This adds SPI NOR support for Khadas VIM3 boards (S922X, A311A and S905D3)
and Odroid-N2 using the same scheme.

Neil Armstrong (4):
  arm64: dts: meson-g12: split emmc pins to select 4 or 8 bus width
  arm64: dts: meson-g12: add the SPIFC nodes
  arm64: dts: khadas-vim3: add SPIFC controller node
  arm64: dts: meson-g12b-odroid-n2: add SPIFC controller node
