Subject: [PATCH v3 0/5] pinctrl: samsung: exynos9 cleanups and fixes
Date: Tue,  2 Dec 2025 18:36:07 +0900	[thread overview]
Message-ID: <20251202093613.852109-1-youngmin.nam@samsung.com> (raw)
In-Reply-To: CGME20251202093024epcas2p1567dddf09e3599867e9dc14a9a234d38@epcas2p1.samsung.com

Several SoCs carried near-duplicate pin bank macro families, making
tables verbose and hard to share when only the bank type (alive/off)
differs.

GS101 had its own helpers even though the newer EXYNOS9_* helpers cover
the same semantics, including per-bank filter control (FLTCON) offsets.

Some pin-bank tables didn't match the SoC TRMs (bank type, EINT class,
or bank names), and FLTCON wasn't always at a contiguous offset from
EINT.

This series does
- Consolidate on EXYNOS9_* pin-bank macros. Pass bank_type explicitly.
- Fix table errors on Exynos2200/7885/8890/8895 per TRM.
- Add explicit per-bank FLTCON offsets and update affected tables.
- Drop GS101-specific macros in favor of EXYNOS9_*.
- Rename gs101_pinctrl_{suspend,resume} ->
  exynos9_pinctrl_{suspend,resume}.

This series was based on the pinctrl/samsung tree [1].

I tested on Exynos850 through boot and verified the pin values as
follows:

$:/sys/kernel/debug/pinctrl/139b0000.pinctrl-samsung-pinctrl# cat pins
registered pins: 42
pin 0 (gpg0-0) 0:gpg0 CON(0x0) DAT(0x0) PUD(0x1) DRV(0x2) CON_PDN(0x2) PUD_PDN(0x1)
pin 1 (gpg0-1) 1:gpg0 CON(0x0) DAT(0x0) PUD(0x1) DRV(0x2) CON_PDN(0x2) PUD_PDN(0x1)
...

Additional testing on the affected Exynos9-era platforms would be
appreciated.

Changes in v2:
  - Added base tree for this series (pinctrl/samsung).
  - Renamed the macro parameter from 'types' to 'bank_type' for clarity
    (struct member remains 'type').
  - Reflowed commit messages (wrap at ~72 cols).
  - Replaced non-ASCII characters with ASCII equivalents.
  - Collected tags:

  - Normalized hex literals to lowercase and removed double spaces.
  - Aligned backslashes in macro definitions to form a vertical column
    for readability.
  - Added missing mailing lists (including linux-kernel) to Cc per
    scripts/get_maintainer.pl.
