[PATCH 0/2] Subject: [PATCH v5 0/2] arm64: Add LECARC ACPI IDs for DesignWare GPIO, SPI

[Thomas Lin]

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

[PATCH 1/2] gpio: dwapb: Add ACPI ID LECA0001 for LECARC SoCs

[Thomas Lin]

Add ACPI ID "LECA0001" for LECARC SoCs that use the DesignWare
GPIO controller with V1 register offsets.

[PATCH 2/2] spi: dw-mmio: Add ACPI ID LECA0002 for LECARC SoCs

[Thomas Lin]

This ID requires a custom initialization function
dw_spi_hssi_no_dma_init() that sets dws->dws.ip to DW_HSSI_ID.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
