Commit Message

Shawn Guo March 10, 2021, 11:12 a.m. UTC
It adds ACPI probe support for pinctrl-sc8180x driver.  We have one
problem with ACPI table, i.e. GIO0 (TLMM) block has one single memory
resource to cover 3 tiles defined by SC8180X.  To follow the hardware
layout of 3 tiles which is already supported DT probe, it adds one
function to replace the original single memory resource with 3 named
ones for tiles.  With that, We can map memory for ACPI in the same way
as DT.

Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
---
Changes for 4:
 - Add sc8180x_pinctrl_add_tile_resources() to massage memory resource
   for ACPI probe.

Changes for v3:
- Remove the use of tiles completely.
- Drop unneed include of acpi.h.

Changes for v2:
- Pass soc_data pointer via .driver_data.
- Drop use of CONFIG_ACPI and ACPI_PTR().
- Add comment for sc8180x_acpi_reserved_gpios[] terminator.

You are reinventing a wheel, i.e. MFD framework. Can you simple utilize
devm_mfd_add_devices()?

Basically you may write an new pure MFD driver (drivers/mfd) that will
instantiate properly the pin control driver.

But wouldn't such driver need to do exactly this, and then set up the
mfd cell and register it? So the new wheel would still be there, just
wrapped in more code?

In contrast to typical MFDs this would still be a single mfd_cell, just
with different set of resources, derived from the mfd device itself.

Are you sure it will take more code?

Yes, I understand the current case, but in my proposal you will have a
separate driver for all quirks needed for this ACPI HID
implementation.

In any case, I just pointed out that MFD is worth considering.

As I said before, there really only is 190 things called "GPIO" on this
platform - the 191 thing is a hack of mine, but it's inclusion here
should depend on how the ACPI system would reset the UFS device - if it
does so at all.

A comment describing the purpose of this function (to split the
IORESOURCE_MEM into three) would be in its place.

sc8180x_pinctrl_add_tile_resources() already printed an error when we
get here, so no need to print another one.


Other than that, I think this looks good!

No, so far I do not see reset is required for ACPI boot.  I will keep it
as 190 to match hardware spec.
