Subject: [PATCH v2 15/20] ARM: mmp: add support for MMP3 SoC
Date: Thu, 22 Aug 2019 11:26:38 +0200 [thread overview]
Message-ID: <20190822092643.593488-16-lkundrak@v3.sk> (raw)
In-Reply-To: <20190822092643.593488-1-lkundrak@v3.sk>
Similar to MMP2, which this patch is based on. Known differencies from MMP2
are:
* Two PJ4B cores instead of one PJ4
* Tauros 3 L2 cache controller instead of Tauros 2
* A GIC interrupt controller optionally used instead of the MMP one
* A TWD local timer
* Different USB2 PHY
* A USB3 SS controller
* More interrupt muxes
Hard to tell what else is different, because documentation is not
available.
Signed-off-by: Lubomir Rintel <lkundrak@v3.sk>

Changes since v1:
- Add CONFIG_COMMON_CLK_MMP2 to streamline the Makefile rule a tiny bit.
