2016-08-04tree-wide: replace config_enabled() with IS_ENABLED()Masahiro Yamada1-1/+1
The use of config_enabled() against config options is ambiguous. In practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the author might have used it for the meaning of IS_ENABLED(). Using IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc. makes the intention clearer. This commit replaces config_enabled() with IS_ENABLED() where possible. This commit is only touching bool config options. I noticed two cases where config_enabled() is used against a tristate option: - config_enabled(CONFIG_HWMON) [ drivers/net/wireless/ath/ath10k/thermal.c ] - config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE) [ drivers/gpu/drm/gma500/opregion.c ] I did not touch them because they should be converted to IS_BUILTIN() in order to keep the logic, but I was not sure it was the authors' intention.

2016-05-13MIPS: JZ4740: Probe OHCI platform device via DTMaarten ter Huurne1-25/+0
The DT fragment will select the ohci-platform driver, since that can handle the JZ4740 OHCI just fine. While I don't have a JZ4740-based board with anything connected to the USB host controller, I did test the generic OHCI driver successfully on a JZ4770-based board. The device is disabled by default; boards that want to use it can override the "status" property. The mass-production Qi LB60 boards don't use the USB host controller.

2015-09-03MIPS: Remove all the uses of custom gpio.hAlban Bedel1-12/+8
Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS machines, and each machine type provides its own gpio.h. However only a handful really implement the GPIO API, most just forward everythings to gpiolib. The Alchemy machine is notable as it provides a system to allow implementing the GPIO API at the board level. But it is not used by any board currently supported, so it can also be removed. For most machine types we can just remove the custom gpio.h, as well as the custom wrappers if some exists. Some of the code found in the wrappers must be moved to the respective GPIO driver. A few more fixes are need in some drivers as they rely on linux/gpio.h to provides some machine specific definitions, or used asm/gpio.h instead of linux/gpio.h for the gpio API.

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 ...
