From a72149e82b65b76d2dae5428a6b211eb43933529 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Tue, 26 Feb 2013 11:34:07 +0900 Subject: pinctrl: core: use devres_release() instead of devres_destroy() devres_release() can simplify the code, because devres_release() will call the destructor for the resource as well as freeing the devres data.

In the pinctrl-single driver, it needs to configure pins with gpio function mode. A new gpio function range should be created in DTS file in below. pinctrl-single,gpio-range = ; range: gpio-range { #pinctrl-single,gpio-range-cells = <3>; }; The gpio-ranges property is used in gpio driver and the pinctrl-single,gpio-range property is used in pinctrl-single driver. 1. gpio-ranges is used for gpio driver in below. gpio-ranges = gpio-ranges = < &pmx0 0 89 1 &pmx0 1 89 1 &pmx0 2 90 1 &pmx0 3 90 1 &pmx0 4 91 1 &pmx0 5 92 1>; 2. gpio driver could get pin offset from gpio-ranges property. pinctrl-single driver could get gpio function mode from gpio_func that is stored in @gpiofuncs list in struct pcs_device. This new pinctrl-single,gpio-range is used as complement for gpio-ranges property in gpio driver.

It appears that what hardware +engineers mean with "GPIO mode" is not necessarily the use case that is +implied in the kernel interface : a pin that you grab from +kernel code and then either listen for input or drive high/low to +assert/deassert some external line. + +Rather hardware engineers think that "GPIO mode" means that you can +software-control a few electrical properties of the pin that you would +not be able to control if the pin was in some other mode, such as muxed in +for a device. + +Example: a pin is usually muxed in to be used as a UART TX line. But during +system sleep, we need to put this pin into "GPIO mode" and ground it. + +If you make a 1-to-1 map to the GPIO subsystem for this pin, you may start +to think that you need to come up with something real complex, that the +pin shall be used for UART TX and GPIO at the same time, that you will grab +a pin control handle and set it to a certain state to enable UART TX to be +muxed in, then twist it over to GPIO mode and use gpio_direction_output() +to drive it low during sleep, then mux it over to UART TX again when you +wake up and maybe even gpio_request/gpio_free as part of this cycle. This +all gets very complicated. + +The solution is to not think that what the datasheet calls "GPIO mode" +has to be handled by the interface. Instead view this as +a certain pin config setting. Look in e.g. +and you find this in the documentation: + + PIN_CONFIG_OUTPUT: this will configure the pin in output, use argument + 1 to indicate high level, argument 0 to indicate low level. + +So it is perfectly possible to push a pin into "GPIO mode" and drive the +line low as part of the usual pin control map. So for example your UART +driver may look like this: + +#include + +struct pinctrl *pinctrl; +struct pinctrl_state *pins_default; +struct pinctrl_state *pins_sleep; + +pins_default = pinctrl_lookup_state(uap->pinctrl, PINCTRL_STATE_DEFAULT); +pins_sleep = pinctrl_lookup_state(uap->pinctrl, PINCTRL_STATE_SLEEP); + +/* Normal mode */ +retval = pinctrl_select_state(pinctrl, pins_default); +/* Sleep mode */ +retval = pinctrl_select_state(pinctrl, pins_sleep); + +And your machine configuration may look like this: +-------------------------------------------------- + +static unsigned long uart_default_mode[] = { + PIN_CONF_PACKED(PIN_CONFIG_DRIVE_PUSH_PULL, 0), +}; + +static unsigned long uart_sleep_mode[] = { + PIN_CONF_PACKED(PIN_CONFIG_OUTPUT, 0), +}; + +static struct pinctrl_map __initdata pinmap[] = { + PIN_MAP_MUX_GROUP("uart", PINCTRL_STATE_DEFAULT, "pinctrl-foo", + "u0_group", "u0"), + PIN_MAP_CONFIGS_PIN("uart", PINCTRL_STATE_DEFAULT, "pinctrl-foo", + "UART_TX_PIN", uart_default_mode), + PIN_MAP_MUX_GROUP("uart", PINCTRL_STATE_SLEEP, "pinctrl-foo", + "u0_group", "gpio-mode"), + PIN_MAP_CONFIGS_PIN("uart", PINCTRL_STATE_SLEEP, "pinctrl-foo", + "UART_TX_PIN", uart_sleep_mode), +}; + +foo_init(void) { + pinctrl_register_mappings(pinmap, ARRAY_SIZE(pinmap)); +} + +Here the pins we want to control are in the "u0_group" and there is some +function called "u0" that can be enabled on this group of pins, and then +everything is UART business as usual. But there is also some function +named "gpio-mode" that can be mapped onto the same pins to move them into +GPIO mode. + +This will give the desired effect without any bogus interaction with the +GPIO subsystem. It is just an electrical configuration used by that device +when going to sleep, it might imply that the pin is set into something the +datasheet calls "GPIO mode" but that is not the point: it is still used +by that UART device to control the pins that pertain to that very UART +driver, putting them into modes needed by the UART. GPIO in the Linux +kernel sense are just some 1-bit line, and is a different use case. + +How the registers are poked to attain the push/pull and output low +configuration and the muxing of the "u0" or "gpio-mode" group onto these +pins is a question for the driver. + +Some datasheets will be more helpful and refer to the "GPIO mode" as +"low power mode" rather than anything to do with GPIO. This often means +the same thing electrically speaking, but in this latter case the +software engineers will usually quickly identify that this is some +specific muxing/configuration rather than anything related to the GPIO +API. + + Board/machine configuration ================================== -- cgit v0.10.2 From 62194200e5e383af2085faf35b6f009364446069 Mon Sep 17 00:00:00 2001 From: Haojian Zhuang Date: Wed, 13 Mar 2013 16:23:57 +0800 Subject: pinctrl: remove pxa pinctrl driver pinctrl-pxa driver doesn't support well on DT mode. Now pinctrl-single could support DT mode & pin configuration. Use pinctrl-single driver to support MMP/PXA silicons instead.

By default for all ABx500 family chip, pin default mode is selected by clearing corresponding bit in GPIOSELx register except for pins which support alternate function, in this case, corresponding bit must be set. But, due to an unlogical hardware implementation, for one particular pin (GPIO11) reverse setting must be done. For that, update the alternate function array by declaring that this pin supports alternate function.

Before this modification, by using a global mutex, deadlock appeared when, for example, a call to pinctrl_pins_show() locked the pinctrl_mutex, called the ops->pin_dbg_show of a particular pin controller. If this pin controller needs I2C access to retrieve configuration information and I2C driver is using pinctrl to drive its pins, a call to pinctrl_select_state() try to lock again pinctrl_mutex which leads to a deadlock. Notice that the mutex grab from the two direction functions was moved into pinctrl_gpio_direction(). For several cases, we can't replace pinctrl_mutex by pctldev->mutex, because at this stage, pctldev is not accessible : - pinctrl_get()/pinctrl_put() - pinctrl_register_maps() So add respectively pinctrl_list_mutex and pinctrl_maps_mutex in order to protect pinctrl_list and pinctrl_maps list instead. Reintroduce pinctrldev_list_mutex in find_pinctrl_by_of_node(), pinctrl_find_and_add_gpio_range() pinctrl_request_gpio(), pinctrl_free_gpio(), pinctrl_gpio_direction(), pinctrl_devices_show(), pinctrl_register() and pinctrl_unregister() to protect pinctrldev_list. Changes v2->v3: - Fix a missing EXPORT_SYMBOL_GPL() for pinctrl_select_state(). Changes v1->v2: - pinctrl_select_state_locked() is removed, all lock mechanism is located inside pinctrl_select_state(). When parsing the state->setting list, take the per-pin-controller driver lock. (Patrice). - Introduce pinctrldev_list_mutex to protect pinctrldev_list in all functions which parse or modify pictrldev_list. (Patrice). - move find_pinctrl_by_of_node() from pinctrl/devicetree.c to pinctrl/core.c in order to protect pinctrldev_list. (Patrice). - Sink mutex:es into some functions and remove some _locked variants down to where the lists are actually accessed to make things simpler. (Linus) - Drop *all* mutexes completely from pinctrl_lookup_state() and pinctrl_select_state() - no relevant mutex was taken and it was unclear what this was protecting against.
