Subject: [PATCH 6/7] ARM:mstar: Add syscon node for "pmsleep" area
Date: Sun, 26 Jul 2020 13:39:47 +0900 [thread overview]
Message-ID: <20200726043948.1357573-7-daniel@0x0f.com> (raw)
In-Reply-To: <20200726043948.1357573-1-daniel@0x0f.com>
MStar v7 SoCs contain a region of registers that are in the always on
domain that the vendor code calls the "pmsleep" area.
This area contains registers for a broad range of functionality and
needs to be shared between drivers.
This patch adds a syscon node for the pmsleep area so that other
drivers can access registers in the area.
