Subject: [PATCH v3 0/4] riscv: rtc: sophgo: add mfd and rtc support for CV1800
Date: Tue, 26 Dec 2023 18:04:27 +0800 [thread overview]
Message-ID: <20231226100431.331616-1-qiujingbao.dlmu@gmail.com> (raw)
This patch serises are to add rtc driver and providers by writing
and reading syscon registers for the CV1800 RISC-V SoC. And add
documentation and nodes to describe System Controller(syscon).
This patch series depends on the clk patch support for Sophgo CV1800 SoC
patch series which can be found at below link:
https://lore.kernel.org/all/IA1PR20MB495354167CE560FC18E28DC5BB90A@IA1PR20MB4953.namprd20.prod.outlook.com/
Changes since v2:
- add mfd support for CV1800
- add rtc to mfd
- using regmap replace iomap
- merge register address in dts
v2: https://lore.kernel.org/lkml/20231217110952.78784-1-qiujingbao.dlmu@gmail.com/
Changes since v1
- fix duplicate names in subject
- using RTC replace RTC controller
- improve the properties of dt-bindings
- using `unevaluatedProperties` replace `additionalProperties`
- dt-bindings passed the test
- using `devm_platform_ioremap_resource()` replace
`platform_get_resource()` and `devm_ioremap_resource()`
- fix random order of the code
- fix wrong wrapping of the `devm_request_irq()` and map the flag with dts
- using devm_clk_get_enabled replace `devm_clk_get()` and
`clk_prepare_enable()`
- fix return style
- add rtc clock calibration function
- use spinlock when write register on read/set time
v1: https://lore.kernel.org/lkml/20231121094642.2973795-1-qiujingbao.dlmu@gmail.com/
