[PATCH 0/5] arm: dts: sc5xx: device tree updates and fixes

[ozndrgt]

From: Ozan Durgut <ozan.durgut@analog.com>

This series introduces updates for Analog Devices SC5xx boards.

It cleans up device trees by renaming GPIO expanders and removing
incorrect SPI flash definitions from the common include file.

For the SC598, this series updates the EZLITE board to the latest
Revision E hardware. It also adds missing GPIO hogs and enables
additional commands for the EZKIT configuration.

[PATCH 3/5] arm: dts: sc5xx: drop SPI flash from common dtsi

[ozndrgt]

From: Philip Molloy <philip.molloy@analog.com>

SPI flash devices are not common across all SC5xx boards. They
already defined in the SoM-specific dtsi files. Keeping the
definition in the common dtsi is therefore incorrect.

[PATCH 4/5] arm: dts: adi: rename GPIO expanders

[ozndrgt]

From: Ozan Durgut <ozan.durgut@analog.com>

The current naming convention for GPIO expanders across ADI SC5xx
device trees is inconsistent. This patch updates the node names to
correct indexing and clarify hardware location.

For SC573, SC584, and SC589 evaluation SBCs, switch to zero-based
indexing to align with standard conventions.

For SC594 and SC598 SoM + carrier evaluation kits, rename the nodes to
crr_gpio_expander. This prefix indicates which board the expander is on.

I tried this series on top of 2026.04-rc1 and ran my usual tests
against an sc573 ezkit and an sc598 rev D som + ezkit carrier board.
Note that to test the rev D board I have to omit dtsi switch to rev E,
but other than that everything looks good to me functionality-wise.
Some commit messages could be expanded (such as adding info about why
wget/fat/gpt/mtd are being enabled), but I don't see a need to
resubmit just for that.

For the series,
