2023-05-29pinctrl: Switch i2c drivers back to use .probe()Uwe Kleine-König
After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

2023-04-14pinctrl: sx150x: Convert to immutable irq_chipLinus Walleij
Convert the driver to immutable irq-chip with a bit of intuition. I switched to consistently using irqd_to_hwirq() consistently while we are at it. As the driver now needs to get the gpio_chip in the .irq_mask and .irq_unmask callbacks, I switched to a pattern where we first fetch the gpio_chip and then the state container from that in two steps. The compiler will do the same thing anyway.

2023-03-13pinctrl: sx150x: drop of_match_ptr for ID tableKrzysztof Kozlowski
The driver will match mostly by DT table (even thought there is regular ID table) so there is little benefit in of_match_ptr (this also allows ACPI matching via PRP0001, even though it might not be relevant here).

2017-01-26pinctrl / gpio: Introduce .set_config() callback for GPIO chipsMika Westerberg
Currently we already have two pin configuration related callbacks available for GPIO chips .set_single_ended() and .set_debounce(). In future we expect to have even more, which does not scale well if we need to add yet another callback to the GPIO chip structure for each possible configuration parameter. Better solution is to reuse what we already have available in the generic pinconf. To support this, we introduce a new .set_config() callback for GPIO chips. The callback takes a single packed pin configuration value as parameter. This can then be extended easily beyond what is currently supported by just adding new types to the generic pinconf enum. If the GPIO driver is backed up by a pinctrl driver the GPIO driver can just assign gpiochip_generic_config() (introduced in this patch) to .set_config and that will take care configuration requests are directed to the pinctrl driver. We then convert the existing drivers over .set_config() and finally remove the .set_single_ended() and .set_debounce() callbacks.

2016-11-08pinctrl-sx150x: Replace sx150x_*_cfg by means of regmap APIAndrey Smirnov
The difference between 8 and 16 pin GPIO expanders can be accomodated by the means of regmap API without resorting to using driver-specific read/write accessors. This change, IMHO, brings the following benefits: - Replaces driver's idiosyncratic way of dealing with mult-register fields with regmap API, which, hopefuly, makes the code a bit easier for a new reader to understand - Removes various multi-read for-loop register read logic from various places in the code and puts it in a signle place - Removes ad-hoc IRQ register caching code in sx150x_irq_bus_sync_unlock, since that functionality is provided by regmap Besided aforementioned benefits this change also implements necessary RegSense byte swap necessary for SX1503 and SX1506 variants of the chip.

2016-10-24pinctrl: Add SX150X GPIO Extender Pinctrl DriverNeil Armstrong
Since the I2C sx150x GPIO expander driver uses platform_data to manage the pins configurations, rewrite the driver as a pinctrl driver using pinconf to get/set pin configurations from DT or debugfs. The pinctrl driver is functionnally equivalent as the gpio-only driver and can use DT for pinconf. The platform_data confirmation is dropped. This patchset removed the gpio-only driver and selects the Pinctrl driver config instead. This patchset also migrates the gpio dt-bindings to pinctrl and add the pinctrl optional properties. The driver was tested with a SX1509 device on a BeagleBone black with interrupt support and on an X86_64 machine over an I2C to USB converter. This is a fixed version that builds and runs on non-OF platforms and on arm based OF. The GPIO version is removed and the bindings are also moved to the pinctrl bindings. Changes since v2 - rebased on v4.9-rc1 - removed MODULE_DEVICE_TABLE as in upstream bb411e771b0e ("gpio: sx150x: fix implicit assumption module.h is present") Changes since v1 - Fix Kconfig descriptions on pinctrl and gpio - Fix Kconfig dependency - Remove oscio support for non-789 devices - correct typo in dt bindings - remove probe reset for non-789 devices Changes since RFC - Put #ifdef CONFIG_OF/CONFIG_OF_GPIO to remove OF code for non-of platforms - No more rely on OF_GPIO config - Moved and enhanced bindings to pinctrl bindings - Removed gpio-sx150x.c - Temporary select PINCTRL_SX150X when GPIO_SX150X - Temporary mark GPIO_SX150X as deprecated Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Tested-by: Peter Rosin <peda@axentia.se> Acked-by: Rob Herring <robh@kernel.org> ested-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
