* genalloc: add name arg to gen_pool_get() and devm_gen_pool_create()Vladimir Zapolskiy2015-09-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change modifies gen_pool_get() and devm_gen_pool_create() client interfaces adding one more argument "name" of a gen_pool object. Due to implementation gen_pool_get() is capable to retrieve only one gen_pool associated with a device even if multiple gen_pools are created, fortunately right at the moment it is sufficient for the clients, hence provide NULL as a valid argument on both producer devm_gen_pool_create() and consumer gen_pool_get() sides. Because only one created gen_pool per device is addressable, explicitly add a restriction to devm_gen_pool_create() to create only one gen_pool per device, this implies two possible error codes returned by the function, account it on client side (only misc/sram). This completes client side changes related to genalloc updates.

* ARM: appropriate __init annotation for const dataNicolas Pitre2015-07-281-1/+1
| | | | | | | | | | Init data marked const should be annotated with __initconst for correctness and not __initdata. In some cases the array gathering references to that data has to be marked const as well. This fixes LTO builds that otherwise fail with section mismatch errors.

* genalloc: rename dev_get_gen_pool() to gen_pool_get()Vladimir Zapolskiy2015-06-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | To be consistent with other genalloc interface namings, rename dev_get_gen_pool() to gen_pool_get(). The original omitted "dev_" prefix is removed, since it points to argument type of the function, and so it does not bring any useful information.

* ARM: at91: cpuidle: Convert to platform driverDaniel Lezcano2013-10-161-8/+19
| | | | | | | | | | | | | | | | | | | | | | | | | Using the platform driver model is a good way to separate the cpuidle specific code from the low level pm code. It allows to remove the dependency between these two components. The platform_device is located in the pm code and a 'set' function has been added to set the standby function from the AT91_SOC_START initialization function. Each SoC with a cpuidle driver will set the standby function in the platform_data field at init time. Then pm code will register the cpuidle platform device. The cpuidle driver will register the platform_driver and use the device's platform_data as a standby callback in the idle path. The at91_pm_enter function contains a { if then else } based on cpu_is_xx similar to what was in cpuidle. This is considered dangerous when adding a new SoC. Like the cpuidle driver, a standby ops is defined and assigned when the SoC init function specifies what is its standby function and reused in the at91_pm_enter's 'case' block.

* ARM: at91: unused variable in at91_pm_verify_clocksArnd Bergmann2012-10-041-2/+3
| | | | | | | | | | | | | | | | The code using the variable 'i' in this function is conditional which results in a harmless compiler warning. Using the IS_ENABLED macro instead of #ifdef makes the code look nicer and gets rid of the warning. Without this patch, building at91sam9263_defconfig results in: /home/arnd/linux-arm/arch/arm/mach-at91/pm.c: In function 'at91_pm_verify_clocks': /home/arnd/linux-arm/arch/arm/mach-at91/pm.c:137:6: warning: unused variable 'i' [-Wunused-variable] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Cc: Nicolas Ferre <nicolas.ferre@atmel.com>
* ARM: at91: sparse irq supportLudovic Desroches2012-07-021-0/+1
| | | | | | | | | | | Enable sparse irq support for multisoc image. It involves to add the NR_IRQS_LEGACY offset to static SoC irq number definitions since NR_IRQS_LEGACY irq descs are allocated before AIC requests irq descs allocation. Move NR_AIC_IRQS macro to a more appropiate place with the purpose to remove mach/irqs.h later.

* ARM: at91/pm_slowclock: function slow_clock() accepts parametersJean-Christophe PLAGNIOL-VILLARD2012-02-231-3/+17
| | | | | | | | | | | | | | Change slow_clock()/at91_slow_clock() prototype to accept the PMC base address and one or two RAM controller addresses by parameters. The r0, r1 and r2 registers are used differently and preserved during function call. Those values are defined in pm.c and slow_clock() function is called from there with its new parameters. This will allow to have a soc independent pm_slowclock. Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Ached-by: Nicolas Ferre <nicolas.ferre@atmel.com>
