[PATCH v2 0/2] gpio: rcar: Add-R-Car S4-8 GPIO support

[PATCH v2 0/2] gpio: rcar: Add-R-Car S4-8 GPIO support

[Geert Uytterhoeven]

	Hi Linus, Bartosz,

This patch series adds support for the Renesas R-Car S4-8 Soc to the
R-Car GPIO DT bindings and driver.  It has been tested with i2c-gpio,
by reading the contents from the I2C EEPROMs on the Spider development
board.

Changes compared to v1:
  - Drop RFC,
  - Split series in DT bindings+driver and DTS series.

Thanks!

[PATCH v2 1/2] dt-bindings: gpio: renesas,rcar-gpio: Add r8a779f0 support

[Geert Uytterhoeven]

Document support for the GPIO controller blocks in the Renesas R-Car
S4-8 (R8A779F0) SoC, including a new family-specific compatible value
for the R-Car Gen4 family.

[PATCH v2 2/2] gpio: rcar: Add R-Car Gen4 support

[Geert Uytterhoeven]

R-Car V3U (R8A779A0) was the first member of the R-Car Gen4 family.
Generalize the support for R-Car V3U to other SoCs in the R-Car Gen4
family by adding a family-specific compatible value.
