[PATCH 0/2] Subject: [PATCH v5 0/2] arm64: Add LECARC ACPI IDs for DesignWare GPIO, SPI
From: Thomas Lin
Date: Wed May 20 2026 - 22:35:16 EST
This patch series adds ACPI identification for LECARC SoCs that
integrate Synopsys DesignWare peripherals.
LECARC platforms use the following ACPI HIDs:
GPIO: LECA0001 (V1 register offsets)
SPI: LECA0002 (requires custom init function)
Patch 1: GPIO – add LECA0001 to dwapb_gpio ACPI match table.
Patch 2: SPI – add LECA0002 and dw_spi_lecarc_init() to spi-dw-mmio,
Changes since v1:
- Revised subject lines to match subsystem style guidelines
- No functional changes
- All the comments from reviews has been fixed
Changes since v2:
- Wrap long commit description lines to 72 columns
- Fix code indentation in spi-dw-mmio.c: use tabs + spaces for alignment
- No functional changes
Changes since v3:
- Start a new thread for each revision
Changes since v4:
- patch to strip away conflicts
