Subject: [v2 resend 00/10] arm/arm64: mediatek: Fix mmsys device probing
Date: Tue, 24 Apr 2018 11:46:57 +0200 [thread overview]
Message-ID: <cover.1524563001.git.mbrugger@suse.com> (raw)
From: Matthias Brugger <mbrugger@suse.com>
Changes since v1:
- add binding documentation
- ddp: use regmap_update_bits
- ddp: ignore EPROBE_DEFER on clock probing
- mfd: delete mmsys_private
- add Reviewed-by and Acked-by tags
---
MMSYS in Mediatek SoCs has some registers to control clock gates (which is
used in the clk driver) and some registers to set the routing and enable
the differnet blocks of the display subsystem.
Up to now both drivers, clock and drm are probed with the same device tree
compatible. But only the first driver get probed, which in effect breaks
graphics on mt8173 and mt2701.
This patch set introduces a new mfd device, which binds against the mmsys
compatible and takes care of probing the needed devices. It was tested on the
bananapi-r2 and the Acer R13 Chromebook.
Matthias Brugger (10):
dt-bindings: mediatek: mmsys: Add support for mfd
drm/mediatek: Use regmap for register access
mfd: mtk-mmsys: Add mmsys driver
drm/mediatek: mt2701: switch to mfd probing.
clk: mediatek: mt2701-mm: switch to mfd device
mfd: mtk-mmsys: Add mt8173 nodes
drm/mediatek: Add mfd support for mt8173
clk: mediatek: mt8173-mm: switch to mfd device
drm: mediatek: Omit warning on probe defers
