[v3 0/5] Mediatek MT8195 power domain support

[Chun-Jie Chen]

This patch series adds power domain support for MT8195
and is based on 5.13-rc3.

change since v2:
- move modification of wakeup capacity to single patch

reason for resend v2:
- miss patch version in series

changes since v1:
- fix signed-off name
- describe more detail in patch 3
- move modification of removing redundant macro to single patch

Chun-Jie Chen (5):
  soc: mediatek: pm-domains: Move power status offset to power domain
    data
  dt-bindings: power: Add MT8195 power domains
  soc: mediatek: pm-domains: Add support for mt8195
  soc: mediatek: pm-domains: Add wakeup capacity support in power domain
  soc: mediatek: pm-domains: Remove unused macro

[v3 1/5] soc: mediatek: pm-domains: Move power status offset to power domain data

[Chun-Jie Chen]

MT8195 has more than 32 power domains so it needs
two set of pwr_sta and pwr_sta2nd registers,
so move the register offset from soc data into power domain data.

[v3 4/5] soc: mediatek: pm-domains: Add wakeup capacity support in power domain

[Chun-Jie Chen]

Due to some power domain needs to keep on for wakeup in system suspend,
so add GENPD_FLAG_ACTIVE_WAKEUP support in Mediatek power domain driver.

[v3 5/5] soc: mediatek: pm-domains: Remove unused macro

[Chun-Jie Chen]

Due to clk resource data will be allocated dynamically by
searching parent count of clk in power domain node, so remove
the unused marco MAX_SUBSYS_CLKS for static allocation.

Future advice: cleanups like this and other fixes should be put in the
front of the series, before any patches that introduce support for new
features or hardware. That way if the new code still needs work,
maintainers can optionally apply the fixes so you don't have to carry
a large patch series forward.

The SCPSYS block is not documented in the datasheets available. However
I did look at all the register and bit offsets and confirmed nothing
overlapped.

There's significant overlap within this block. This means when the base
VDOSYS0 power domain is on, all the overlapped protection bits get turned
off. I'm not sure that's correct.

Same goes for IMG, which overlaps with IPE.

And here, IMG and IPE are the same.

All these MT8195_TOP_AXI_PROT_EN_* bit offsets aren't documented. Besides
the huge overlap above, it seems NNA also includes NNA0 and NNA1.

I think this patch should have a fixes tag:

Fixes: 59b644b01cf4 ("soc: mediatek: Add MediaTek SCPSYS power domains")

And it should be either the first or second patch of the series, either
before or just after the cleanup (remove unused macro) patch.

Otherwise,

Ok, I will re-order the patches in next series.
Thanks for your comment.

Because the timing of enable & disable protection are different, we
duplicate some control bit in different power domain.

For example: IMG & IPE are parent and child relation, so IMG must power
on before IPE, IPE must power off before IMG.
We want to clear some bits (protection disable) when power on IMG and
set some bits (protection enable) when power off IPE.

The detail of MT8195_TOP_AXI_PROT_EN_* bit is related to the bus
design, so we don't descript the detail in datasheet.

I will remove the unused power domain and data (like NNA) because these
are not used in 8195 chrome project.
