Subject: [PATCH v4 4/4] soc: amlogic: meson-ee-pwrc: add support for the Meson GX SoCs
Date: Fri, 15 May 2020 22:47:09 +0200 [thread overview]
Message-ID: <20200515204709.1505498-5-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20200515204709.1505498-1-martin.blumenstingl@googlemail.com>
Add support for the Meson GX SoCs to the meson-ee-pwrc driver.
The power domains on the GX SoCs are very similar to G12A. The only
known differences so far are:
- The GX SoCs do not have the HHI_VPU_MEM_PD_REG2 register (for the
VPU power-domain)
- The GX SoCs have an additional reset line called "dvin"
