arm64: dts: renesas: Eagle V3M PFC/GPIO update and SPI NOR flash bitbang hack
[PATCH/RFC 01/03] arm64: dts: renesas: r8a77970: Add PFC node for Eagle V3M
[PATCH/RFC 02/03] arm64: dts: renesas: r8a77970: Add GPIO nodes
[PATCH/RFC 03/03] arm64: dts: renesas: eagle: NOR flash SPI bitbang prototype
This series gives the R-Car V3M SoC and the Eagle board an update when
it comes to PFC and GPIO support. Also to test the two QSPI channels are
configured as GPIOs and via SPI bitbang the SPI NOR flash chips are probed.
Patch 1 and 2 are rather ready for upstream merge:
Signed-off-by: Magnus Damm <damm+renesas@opensource.se>
Patch 3 is just for testing purpose and shall not be picked up:
