| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main issue is that the current documentation talks about the non-existent function pwm_get_last_applied_state. (This was right in the context of https://lore.kernel.org/linux-pwm/20210406073036.26857-1-u.kleine-koenig@pengutronix.de/ but was then missed to adapt when this patch was reduced to a documentation update.) While at is also clarify "last applied PWM state" to "PWM state that was passed to the last invocation of pwm_apply_state()" to better distinguish to the last actually implemented state and reword to drop a word repetition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given that lowlevel drivers usually cannot implement exactly what a consumer requests with pwm_apply_state() there is some rounding involved. pwm_get_state() returns the setting that was requested most recently by the consumer (opposed to what was actually implemented in hardware in reply to the last request).

Core changes: - A semantic change to handle pinmux and pinconf in explicit order while up until now we depended on the semantic order in the device tree. The device tree is a functional programming language and does not imply any order, so the right thing is for the pin control core to provide these semantics. - Add a new pinmux-select debugfs file which makes it possible to go in and select functions for a pin manually (iteratively, at the prompt) for debugging purposes. - Fixes to gpio regmap handling for a new pin control driver making use of regmap-gpio. - Use octal permissions on debugfs files. New drivers: - A massive rewrite of the former custom pin control driver for MIPS Broadcom devices to instead use the pin control subsystem. New pin control drivers for BCM6345, BCM6328, BCM6358, BCM6362, BCM6368, BCM63268 and BCM6318 SoC variants are implemented. - Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and PMR735B in the Qualcomm PMIC GPIO driver. Also the two GPIOs on PM8008 are supported. - Support for the Rockchip RK3568/RK3566 pin controller. - Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and X2000. - Support for Mediatek MTK8195. - Add a new Xilinx ZynqMP pin control driver. Driver improvements and non-urgent fixes: - Modularization and improvements of the Rockchip drivers. - Some new pins added to the description of new Renesas SoCs. - Clarifications of the GPIO base calculation in the Intel driver. - Fix the function names for the MPP54 and MPP55 pins in the Armada CP110 pin controller. - GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350. - Support for ACPI probing of the Qualcomm SC8180x. - Fix interrupt clear status on rockchip - Fix some missing pins on the Ingenic JZ4770, some semantic fixes for the behaviour of the Ingenic pin controller. Add DMIC pins for JZ4780, X1000, X1500 and X1830. - A slew of janitorial like of_node_put() calls" * tag 'pinctrl-v5.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (99 commits) pinctrl: Add Xilinx ZynqMP pinctrl driver support firmware: xilinx: Add pinctrl support pinctrl: rockchip: do coding style for mux route struct pinctrl: Add PIN_CONFIG_MODE_PWM to enum pin_config_param pinctrl: Introduce MODE group in enum pin_config_param pinctrl: Keep enum pin_config_param ordered by name dt-bindings: pinctrl: Add binding for ZynqMP pinctrl driver pinctrl: core: Fix kernel doc string for pin_get_name() pinctrl: mediatek: use spin lock in mtk_rmw pinctrl: add drive for I2C related pins on MT8195 pinctrl: add pinctrl driver on mt8195 dt-bindings: pinctrl: mt8195: add pinctrl file and binding document pinctrl: Ingenic: Add pinctrl driver for X2000. pinctrl: Ingenic: Add pinctrl driver for JZ4775. pinctrl: Ingenic: Add pinctrl driver for JZ4755. pinctrl: Ingenic: Add pinctrl driver for JZ4750. pinctrl: Ingenic: Add pinctrl driver for JZ4730. dt-bindings: pinctrl: Add bindings for new Ingenic SoCs. pinctrl: Ingenic: Reformat the code. pinctrl: Ingenic: Add DMIC pins support for Ingenic SoCs. ...

Fill in the three required .driver members directly instead of copying data into them during mdev_register_driver(). Further the to_mdev_driver() function doesn't belong in a public header, just inline it into the two places that need it. Finally, we can now clearly see that 'drv' derived from dev->driver cannot be NULL, firstly because the driver core forbids it, and secondly because NULL won't pass through the container_of(). Remove the dead code.

Particularly in its struct mdev_driver functions, the whole point of a bus's struct device_driver wrapper is to provide type safety compared to the default struct device_driver. Further, the driver core standard is for bus drivers to expose their device structure in their public headers that can be used with container_of() inlines and '&foo->dev' to go between the class levels, and '&foo->dev' to be used with dev_err/etc driver core helper functions. Move 'struct mdev_device' to mdev.h Once done this allows moving some one instruction exported functions to static inlines, which in turns allows removing one of the two grotesque symbol_get()'s related to mdev in the core code.

| * | vfio: Split creation of a vfio_device into init and register opsJason Gunthorpe2021-04-061-13/+18

This is the first step to bring some type-safety to the vfio interface by allowing the replacement of 'void *' and 'struct device *' inputs with a simple and clear 'struct vfio_device *' For now the self-allocating vfio_add_group_dev() interface is kept so each user can be updated as a separate patch. The expected usage pattern is driver core probe() function: my_device = kzalloc(sizeof(*mydevice)); vfio_init_group_dev(&my_device->vdev, dev, ops, mydevice); /* other driver specific prep */ vfio_register_group_dev(&my_device->vdev); dev_set_drvdata(dev, my_device); driver core remove() function: my_device = dev_get_drvdata(dev); vfio_unregister_group_dev(&my_device->vdev); /* other driver specific tear down */ kfree(my_device); Allowing the driver to be able to use the drvdata and vfio_device to go to/from its own data. The pattern also makes it clear that vfio_register_group_dev() must be last in the sequence, as once it is called the core code can immediately start calling ops. The init/register gap is provided to allow for the driver to do setup before ops can be called and thus avoid races.

Introduce a new ioremap() variant to handle this case. ioremap_np() returns NULL on arches that do not implement this variant. sparc64 is the only architecture that needs to be touched directly, because it includes neither of the generic io.h or iomap.h headers. This adds the IORESOURCE_MEM_NONPOSTED flag, which maps to this variant and marks a given resource as requiring non-posted mappings. This is implemented in the resource system because it is a SoC-level requirement, so existing drivers do not need special-case code to pick this ioremap variant. Then this is implemented in devres by introducing devm_ioremap_np(), and making devm_ioremap_resource() automatically select this variant when the resource has the IORESOURCE_MEM_NONPOSTED flag set.
