category: feature (SPI ACPI for Hi1620)
bugzilla: 5443
CVE: NA

TPM chip on D06 is SPI based, so we need to add SPI ACPI support
for Hi1620.

Two patches already merged for 4.21, but the core support for spi
has another patchset needs lots of refactor, so just use the patch
from Fang Jian to enable this feature on 4.19

[PATCH 1/4] spi: dw-mmio: add ACPI support
[PATCH 2/4] ACPI / APD: Add clock frequency for Hisilicon Hip08 SPI controller
[PATCH 3/4] spi: add ACPI support for SPI controller chip select lines(cs-gpios)
[PATCH 4/4] hulk_defconfig: ensble SPI designware driver for Hi1620
--------------------------------------------------

The SPI clock frequency of Designware IP for Hisilicon Hip08 is 250M.

The ACPI ID used is "HISI0173".
