Subject: [PATCH v4 0/7] ASPEED sgpio driver enhancement.
Date: Mon, 7 Jun 2021 15:15:05 +0800 [thread overview]
Message-ID: <20210607071514.11727-1-steven_lee@aspeedtech.com> (raw)
AST2600 SoC has 2 SGPIO master interfaces one with 128 pins another one
with 80 pins, AST2500/AST2400 SoC has 1 SGPIO master interface that
supports up to 80 pins.
In the current driver design, the max number of sgpio pins is hardcoded
in macro MAX_NR_HW_SGPIO and the value is 80.
For supporting sgpio master interfaces of AST2600 SoC, the patch series
contains the following enhancement:
- Convert txt dt-bindings to yaml.
- Update aspeed-g6 dtsi to support the enhanced sgpio.
- Define max number of gpio pins in ast2600 platform data. Old chip
uses the original hardcoded value.
- Support muiltiple SGPIO master interfaces.
- Support up to 128 pins.
- Support wdt reset tolerance.
- Fix irq_chip issues which causes multiple sgpio devices use the same
irq_chip data.
- Replace all of_*() APIs with device_*().
Changes from v3:
* Split dt-bindings patch to 2 patches
* Rename ast2600-sgpiom1 compatible with ast2600-sgiom-128
* Rename ast2600-sgpiom2 compatible with ast2600-sgiom-80
* Correct the typo in commit messages.
* Fix coding style issues.
* Replace all of_*() APIs with device_*().
Changes from v2:
* Remove maximum/minimum of ngpios from bindings.
* Remove max-ngpios from bindings and dtsi.
* Remove ast2400-sgpiom and ast2500-sgpiom compatibles from dts and
driver.
* Add ast2600-sgpiom1 and ast2600-sgpiom2 compatibles as their max
number of available gpio pins are different.
* Modify functions to pass aspeed_sgpio struct instead of passing
max_ngpios.
* Split sgpio driver patch to 3 patches
Changes from v1:
* Fix yaml format issues.
* Fix issues reported by kernel test robot.
Please help to review.
Thanks,
Steven
