| * | ARM: at91: PIT: Use of_have_populated_dt instead of CONFIG_OFMaxime Ripard2014-09-021-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, the machines, even when CONFIG_OF was enabled, were calling at91sam926x_ioremap_pit to try to map the PIT address using the defined physical address. Obviously, with DT, it's not appropriate anymore, and some code was added to the function to deal with this case. Unfortunately, this code was conditionned on CONFIG_OF, which can be enabled, even though no DT was actually used, which would result in such a case, to this code being executed, without any reason. Moreover, the logic that was here before to bail out of the function just check in the DT to see if the PIT node is there, which is the case in all our DTSI. All this can be made much more straightforward just by using of_have_populated_dt to bail out.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, the pit_cycle computation was dividing the rate by HZ, rounding to the closest integer, but without using the appropriate macro.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The generic.h header file doesn't have any safe guards against multiple inclusion. It only worked so far because all the symbols defined in it were extern, but this is a rather fragile assumption.

| * | ARM: at91: fix ramc standby function registrationAlexandre Belloni2014-09-011-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the for_each_matching_node loop, we end up with a null value for np. Then, of_match_node() is not matching anything and we can't register the standby function and "ramc no standby function available" is printed. Fix that by selecting the first available standby function. For now, at91_pm_set_standby doesn't support multiple different standby functions and no existing SoCs have different RAM controllers.

This patch adds the ability to set one of three hardware options for drive strengths of low, medium or high for the each pin. The actual current output of the chip based on the setting is defined in the datasheets and varies per pins separate from banks and with supply voltage. This patch adds three new dt-bindings that allow setting the strength when configuring pins. By default, no change will be made to the drive strength of a pin from its reset value. Due to the difference between the register addresses of the SAMA5 and SAM9x5 series, a new sama5d3-pinctrl id was added.

The rationale is: well what were we supposed to do if there is an error code? Not much: print an error message. And gpiolib already does that. So make this function return void eventually - Some cleanups of hairy gpiolib code, make some functions not to be used outside the library private and make sure they are not exported, remove gpiod_lock/unlock_as_irq() as the existing function is for driver-internal use and fine as it is, delete gpio_ensure_requested() as it is not meaningful anymore - Support the GPIOF_ACTIVE_LOW flag from gpio_request_one() function calls, which is logical since this is already supported when referencing GPIOs from e.g. device trees - Switch STMPE, intel-mid, lynxpoint and ACPI (!) to use the gpiolib irqchip helpers cutting down on GPIO irqchip boilerplate a bit more - New driver for the Zynq GPIO block - The usual incremental improvements around a bunch of drivers - Janitorial syntactic and semantic cleanups by Jingoo Han, and Rickard Strandqvist especially" * tag 'gpio-v3.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (37 commits) MAINTAINERS: update GPIO include files gpio: add missing includes in machine.h gpio: add flags argument to gpiod_get*() functions MAINTAINERS: Update Samsung pin control entry gpio / ACPI: Move event handling registration to gpiolib irqchip helpers gpio: lynxpoint: Convert to use gpiolib irqchip gpio: split gpiod board registration into machine header gpio: remove gpio_ensure_requested() gpio: remove useless check in gpiolib_sysfs_init() gpiolib: Export gpiochip_request_own_desc and gpiochip_free_own_desc gpio: move gpio_ensure_requested() into legacy C file gpio: remove gpiod_lock/unlock_as_irq() gpio: make gpiochip_get_desc() gpiolib-private gpio: simplify gpiochip_export() gpio: remove export of private of_get_named_gpio_flags() gpio: Add support for GPIOF_ACTIVE_LOW to gpio_request_one functions gpio: zynq: Clear pending interrupt when enabling a IRQ gpio: drop retval check enforcing from gpiochip_remove() gpio: remove all usage of gpio_remove retval in driver/gpio devicetree: Add Zynq GPIO devicetree bindings documentation ...
