soc: renesas: rz-sysc: Add syscon/regmap support

2025-08-20T06:35:55+00:00

The RZ/G3E system controller has various registers that control or report
some properties specific to individual IPs. The regmap is registered as a
syscon device to allow these IP drivers to access the registers through the
regmap API.

As other RZ SoCs might have custom read/write callbacks or max-offsets,
register a custom regmap configuration.

[claudiu.beznea:
 - do not check the match->data validity in rz_sysc_probe() as it is
   always valid
 - dinamically allocate regmap_cfg]

treewide: rename GPIO set callbacks back to their original names

2025-08-07T08:07:06+00:00

The conversion of all GPIO drivers to using the .set_rv() and
.set_multiple_rv() callbacks from struct gpio_chip (which - unlike their
predecessors - return an integer and allow the controller drivers to
indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
one sweeping change.

soc: renesas: Sort Renesas Kconfig configs

2025-07-08T09:55:31+00:00

Renesas Kconfig is using "SoC serial number" for CONFIG symbol, but is
using "SoC chip name" for menu description. Because of it, it looks
random order when we run "make menuconfig".

commit 6d5aded8d57fc ("soc: renesas: Sort driver description title")
sorted Renesas Kconfig by menu description title order, but it makes
confusable to add new config.

Let's unify "ARMxx Platform support for ${CHIP_NUMBER} (${CHIP_NAME}),
and sort it again.

soc: renesas: pwc-rzv2m: Use new GPIO line value setter callbacks

2025-06-13T09:21:53+00:00

struct gpio_chip now has callbacks for setting line values that return
an integer, allowing to indicate failures. Convert the driver to using
them.
