[cip-dev] [PATCH 4.4.y-cip 2/5] spi: rspi: Add r8a77470 to the compatible list

[Biju Das]

From: Fabrizio Castro <fabrizio.castro@bp.renesas.com>

commit df80e0478972260bf285c5ed33f99b2424fba2af upstream.

Add r8a77470 to the list of examples with soctypes.
No driver change is needed as "renesas,qspi" will activate
the right code within the corresponding driver.

[cip-dev] [PATCH 4.4.y-cip 3/5] mtd: spi-nor: Add support for is25lp016d

[Biju Das]

commit b422847877e35d6818f65cb359a60f529fe22c4b upstream.

The is25lp016d is found on the iwg23s from iWave, therefore
add driver support for it so that we can upstream board support.
