[PATCH 0/3] iio: adc: rcar-gyroadc: Misc improvements

[Geert Uytterhoeven]

	Hi Jonathan, Marek,

This patch series contains a few improvements for the driver for the
R-Car GyroADC block, which can be found on R-Car Gen2 (arm32) and Gen3
(arm64) SoCs.

Thanks!

[PATCH 1/3] iio: adc: rcar-gyroadc: Cast pointer to uintptr_t to fix warning on 64-bit

[Geert Uytterhoeven]

On 64-bit:

    drivers/iio/adc/rcar-gyroadc.c: In function 'rcar_gyroadc_parse_subdevs':
    drivers/iio/adc/rcar-gyroadc.c:352:15: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
       childmode = (unsigned int)of_id->data;
		   ^

Cast the pointer to uintptr_t instead of unsigned int to fix this.

Currently this driver can be enabled on arm32 only, but the hardware
block can be found in some R-Car Gen3 SoCs, which are arm64.

[PATCH 2/3] iio: adc: rcar-gyroadc: Enable compile-testing on non-ARM

[Geert Uytterhoeven]

The rcar-gyroadc driver compiles fine on other platforms, hence increase
compile coverage.

[PATCH 3/3] iio: adc: rcar-gyroadc: Use of_device_get_match_data() helper

[Geert Uytterhoeven]

Use the of_device_get_match_data() helper instead of open coding.
Note that the rcar-gyroadc driver is used with DT only, so there's
always a valid match.

Applied to the togreg branch of iio.git and pushed out as testing for the
autobuilders to play with it.
