Subject: [RFC PATCH v2 0/6] Add Pinctrl driver for Starfive JH8100 SoC
Date: Tue, 20 Feb 2024 14:42:40 +0800 [thread overview]
Message-ID: <20240220064246.467216-1-yuklin.soo@starfivetech.com> (raw)
Starfive JH8100 SoC consists of 4 pinctrl domains - sys_east,
sys_west, sys_gmac, and aon. This patch series adds pinctrl
drivers for these 4 pinctrl domains and this patch series is
depending on the JH8100 base patch series in [1] and [2].
The relevant dt-binding documentation for each pinctrl domain has
been updated accordingly.

Changes in v2:
- Add "(always-on)" to document title to clarify acronym AON.
- Replace "drive-strength" by "drive-strength-microamp".
- Update "slew-rate" property in sys-east, sys-west, and aon document.
- remove redundant "bindings" from commit subject and message.
- Change regular expression "-[0-9]+$" to "-grp$" to standardize client
node names to end with suffix "-grp" instead of "-<numerical _number>".
- Use 4 spaces indentation for DTS examples.
- Update DTS examples in sys-east, sys-west, and aon document with client
driver pinmuxing.
- Remove redundant syscon and gmac macros from dt-binding header file.
- Remove redundant register macros from dt-binding header file.
- Add "wakeup-gpios" and "wakeup-source" to aon document.
- Add "gpio-line-names" to sys-east and sys-west document.
- Update the description of syscon register usage in each document.
- Update sys-gmac and aon document with information of GMAC voltage.
reference syscon and GMAC pad syscon.
- Fix the pinctrl device nodes compatible string too long issue.
- Move all common codes from subdrivers to the main driver.
- Change the commit log to "add main and sys_east driver" to indicate
the commit of both main and sys-east driver.
- Turn pin_to_hwirq macro to a static inline function to hide gpio
internal detail, and also, for easier code readability.
- Change "JH8100_PADCFG_BIAS" to "JH8100_PADCFG_BIAS_MASK".
- Change "#define JH8100_PADCFG_DS_4MA BIT(1)" to
#define JH8100_PADCFG_DS_4MA (1U << 1)".
- Replace "jh8100_gpio_request" by "pinctrl_gpio_request".
- Replace "jh8100_gpio_free" by "pinctrl_gpio_free".
- Replace "jh8100_gpio_set_config" by "gpiochip_generic_config".
- Use irq_print_chip function to display irqchip name to user space.
- Use girq to represent GPIO interrupt controller.
- Update code to ensure wakeup-gpios is always an input line.
- Remove the jh8100_gpio_add_pin_ranges function and use gpio-ranges
in device tree to provide information for GPIO core to add pin range
for each pinctrl.
- Change "StarFive GPIO chip registered" to "StarFive JH8100 GPIO chip
registered".
