soc: renesas: rz-sysc: Populate readable_reg/writeable_reg in regmap config

2025-12-18T13:02:59+00:00

[ Upstream commit c432180a7d95081353a96fd6d5bd75b0fc8a27c3 ] Not all system controller registers are accessible from Linux. Accessing such registers generates synchronous external abort. Populate the readable_reg and writeable_reg members of the regmap config to inform the regmap core which registers can be accessed. The list will need to be updated whenever new system controller functionality is exported through regmap.

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.

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. Signed-off-by: Bartosz Golaszewski

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.
