soc: mediatek: pm-domains: Add a power domain names for mt8183

2021-05-19T08:30:01+00:00

commit e57b8112258ed46dff23b49d6e400f54a8dbf1c3 upstream.

Add the power domains names for the mt8183 SoC. This removes the debugfs
errors like the following:

  debugfs: Directory 'power-domain' with parent 'pm_genpd' already present!

soc: mediatek: pm-domains: Add a meaningful power domain name

2021-05-19T08:30:00+00:00

commit 022b02b4505ecea5eda02b18683531e49f7d8eb7 upstream.

Add the power domains names to the power domain struct so we
have meaningful name for every power domain. This also removes the
following debugfs error message.

  [    2.242068] debugfs: Directory 'power-domain' with parent 'pm_genpd' already present!
  [    2.249949] debugfs: Directory 'power-domain' with parent 'pm_genpd' already present!

soc: mediatek: mmsys: Specify HAS_IOMEM dependency for MTK_MMSYS

2020-12-10T14:33:56+00:00

Because mtk-mmsys uses the 'devm_platform_ioremap_resource' function, it
should depend on HAS_IOMEM.

soc: mediatek: mmsys: Use devm_platform_ioremap_resource()

2020-11-27T23:37:12+00:00

For the common platform_get_resource()+devm_platform_ioremap() combination,
there is a helper, so use it and make the code a bit more compact.

MMSYS is the driver which controls the routing of these DDP components,
so the definition of the mtk_ddp_comp_id enum should be placed in mtk-mmsys.h

soc: mediatek: add mt6779 devapc driver

2020-11-27T23:28:25+00:00

MediaTek bus fabric provides TrustZone security support and data
protection to prevent slaves from being accessed by unexpected
masters.
The security violation is logged and sent to the processor for
further analysis or countermeasures.

Any occurrence of security violation would raise an interrupt, and
it will be handled by mtk-devapc driver. The violation
information is printed in order to find the murderer.

soc / drm: mediatek: cmdq: Remove timeout handler in helper function

2020-11-27T22:35:34+00:00

For each client driver, its timeout handler need to dump hardware register
or its state machine information, and their way to detect timeout are
also different, so remove timeout handler in helper function and
let client driver implement its own timeout handler.

soc: mediatek: pm-domains: Add default power off flag

2020-11-27T11:04:43+00:00

For some power domain, like conn on MT8192, it should be default OFF.
Because the power on/off control relies the function of connectivity chip
and its firmware. And if project choose other chip vendor solution,
those necessary connectivity functions will not provided.
