2.43.0
Add various clock controllers found in the MT7988 SoC to existing
bindings (if applicable) and add files for the new ethwarp, mcusys
and xfi-pll clock controllers not previously present in any SoC.
Signed-off-by: Daniel Golle <[email protected]>
---
v4:
* add subnodes for controllers acting as MFD
v3:
* move clock bindings to clock folder
* drop ti,syscon-reset from bindings and example
* merge mcusys with topckgen bindings
v2:
* dropped unused labels
* add 'type: object' declaration for reset-controller found in new
ethwarp controller and represented as ti,syscon-reset
* rebase on top of
"dt-bindings: arm: mediatek: move ethsys controller & convert to DT schema"

From: Sam Shih <[email protected]>
Introduce pcw_chg_shfit control to replace hardcoded PCW_CHG_MASK macro.
This will needed for clocks on the MT7988 SoC.

2.43.0
From: Sam Shih <[email protected]>
Add APMIXED, ETH, INFRACFG and TOPCKGEN clock drivers which are
typical MediaTek designs.
Also add driver for XFIPLL clock generating the 156.25MHz clock for
the XFI SerDes. It needs an undocumented software workaround and has
an unknown internal design.

I think that there was a bit of misunderstanding here: I said 100cols, and that's
fine, but I wanted you to do that with everything but the macros, following what
was done in all the other MediaTek clock drivers.
Can you please change the macros again?
Also, there's some discrepancy in the usage of tabulations vs spaces, please fix.
#define PLL(....)*TAB*\
....
{ \
.id = _id, \
.name = _name, \
.reg = _reg, \
.pwr_reg = _pwr_reg, \
.en_mask = _en_mask, \
...etc etc etc... \
}
Thanks,
Angelo

NACK! This is not the right way to do it. Please do *not* use ti,syscon-reset.
Declare your resets in the relevant clock controller driver, like was done with
all (or the vast majority of) the other MediaTek clock drivers.
This means that you don't need simple-mfd here (and probably syscon as well).

Ok this is better - please call this "pcw_chg_bit" (same for the definition).
Also, since it is impossible for PCW_CHG to be 0, please add a sanity check at
the beginning of function mtk_clk_register_pll_ops(), like so:
if (!data->pcw_chg_bit) {
pr_warn("Invalid PCW_CHG bit for pll %s", data->name);
return ERR_PTR(-EINVAL);
}
...like that, we're fully covered for eventual mistakes during porting (etc).
Cheers,
Angelo

You probably don't need these 2 headers and the implicit includes
of_device.h makes are dropped now in linux-next. Please check what you
actually need and make them explicit.
