* | of/irq: Fix lookup to use 'interrupts-extended' property firstFlorian Fainelli2014-08-161-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case the Device Tree blob passed by the boot agent supplies both an 'interrupts-extended' and an 'interrupts' property in order to allow for older kernels to be usable, prefer the new-style 'interrupts-extended' property which conveys a lot more information. This allows us to have bootloaders willingly maintaining backwards compatibility with older kernels without entirely deprecating the 'interrupts' property. Update the bindings documentation to describe a situation where both the 'interrupts-extended' and the 'interrupts' property are present, and which one takes precedence over the other.

This patch reconfigures dat1 as a GPIO before going to suspend. SDIO interrupts are detected with the GPIO, the GPIO will only wake the module from suspend, SDIO irq detection will still happen through the IP block. Idea of remuxing the pins by Tony Lindgren.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There have been various patches floating around for enabling the SDIO IRQ for hsmmc, but none of them ever got merged. Probably the reason for not merging the SDIO interrupt patches has been the lack of wake-up path for SDIO on some omaps that has also needed remuxing the SDIO DAT1 line to a GPIO making the patches complex. This patch adds the minimal SDIO IRQ support to hsmmc for omaps that do have the wake-up path. For those omaps, the DAT1 line need to have the wake-up enable bit set, and the wake-up interrupt is the same as for the MMC controller. This patch has been tested on am3730 es1.2 with mwifiex connected to MMC3 with mwifiex waking to Ethernet traffic from off-idle mode. Note that for omaps that do not have the SDIO wake-up path, this patch will not work for idle modes and further patches for remuxing DAT1 to GPIO are needed. Based on earlier patches [1][2] by David Vrabel <david.vrabel@csr.com>, Steve Sakoman <steve@sakoman.com> For now, only support SDIO interrupt if we are booted with a separate wake-irq configued via device tree. This is because omaps need the wake-irq for idle states, and some omaps need special quirks. And we don't want to add new legacy mux platform init code callbacks any longer as we are moving to DT based booting anyways. To use it, you need to specify the wake-irq using the interrupts-extended property.

We should have had the flags there from the beginning it seems, now we need to clean up the mess. There is a plan on how to move forward here devised by Alexandre Courbot and Mark Brown - Split off a special <linux/gpio/machine.h> header for the board gpio table registration, as per example from the regulator subsystem - Start to kill off the return value from gpiochip_remove() by removing the __must_check attribute and removing all checks inside the drivers/gpio directory. 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 ...
