Subject: [PATCH 03/18] media: hantro: make G1_REG_SOFT_RESET Rockchip specific
Date: Mon, 12 Oct 2020 23:59:42 +0300
Message-ID: <20201012205957.889185-4-adrian.ratiu@collabora.com> (raw)
In-Reply-To: <20201012205957.889185-1-adrian.ratiu@collabora.com>

This register is not documented in either the G1 or VC8000D register
maps and on VC8000D there is a conflict because at the same offset the
VPU IP defines another register with a very different meaning.

What likely happened is the HW integrator which uses only the G1 IP
core added some reset/control logic at the end of the VPU map, so
it makes sense to make this register RK-specific.
