Subject: serial: 8250_dw: add ACPI support for uart on Hisilicon Hip05 SoC
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e06b6b854163a7f9931d6e0d859b9378a23fe7af;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

serial: 8250_dw: add ACPI support for uart on Hisilicon Hip05 SoC

Add ACPI identifier for UART on Hisilicon Hip05 SoC, be careful that
it is not 16550 compatible, and "reg-io-width" and "reg-shift" need
be set properly by _DSD method in DSDT.
