ARM: dove: Remove CLK_IS_ROOT

2016-04-27T11:55:52+00:00

This flag is a no-op now (see commit 47b0eeb3dc8a "clk: Deprecate CLK_IS_ROOT", 2016-02-02) so remove it. Cc: Andrew Lunn Signed-off-by: Stephen Boyd Signed-off-by: Gregory CLEMENT

ARM: orion: only select I2C_BOARDINFO when using I2C

2016-02-25T14:37:16+00:00

If we select I2C_BOARDINFO and I2C is disabled, we get a harmless Kconfig warning: warning: (MACH_DOVE_DB && MACH_DB88F5281 && MACH_RD88F5182 && MACH_RD88F5182_DT && MACH_KUROBOX_PRO && MACH_DNS323 && MACH_LINKSTATION_PRO && MACH_LINKSTATION_LSCHL && MACH_LINKSTATION_LS_HGL && MACH_NET2BIG) selects I2C_BOARDINFO which has unmet direct dependencies (I2C) Making the select itself conditional avoids the warning and makes the kernel slightly smaller as the compiler will be able to drop the unused board info.

ARM: dove: convert legacy dove to PMU support

2015-12-08T12:23:14+00:00

Since Dove has non-DT support for various facilities in the PMU, convert the legacy support to use the new PMU driver. Acked-by: Arnd Bergmann Signed-off-by: Russell King Signed-off-by: Gregory CLEMENT

ARM: orion: use SPARSE_IRQ everywhere

2015-12-07T17:17:07+00:00

As a preparation for multiplatform support, this moves all the code using plat-orion over to use sparse irq support, which is enabled implicitly for multiplatform. In particular, the hardcoded NR_IRQS macro gets replaced with a machine specific one that is set in the machine descriptor in order to set up a static mapping for all legacy interrupts.

ARM: orion: always use MULTI_IRQ_HANDLER

2015-12-07T17:16:42+00:00

As a preparation for multiplatform support, this enables the MULTI_IRQ_HANDLER code unconditionally on dove and orion5x, and introduces the respective code on mv78xx0, which did not have it so far. The classic entry-macro.S files are removed as they are now obsolete. Signed-off-by: Arnd Bergmann Acked-by: Andrew Lunn Signed-off-by: Gregory CLEMENT

ARM: orion: move watchdog setup to mach-orion5x

2015-12-07T17:09:32+00:00

The watchdog device node is created in plat-orion/common.c but depends on the bridge address that is platform specific, so as a preparation for orion multiplatform support, we move it out of the common code into orion5x and dove. At the moment, dove does not use the watchdog, so I'm marking the function as __maybe_unused for the moment. The compiler will be able to compile out the device definition this way, and we can easily add it later. Signed-off-by: Arnd Bergmann Acked-by: Andrew Lunn Signed-off-by: Gregory CLEMENT

genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51+00:00

Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help! Signed-off-by: Thomas Gleixner Cc: Julia Lawall Cc: Jiang Liu

ARM: kill off set_irq_flags usage

2015-07-28T11:58:13+00:00

set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

ARM/dove: Prepare pmu_irq_handler for irq argument removal

2015-07-13T12:59:15+00:00

The irq argument of most interrupt flow handlers is unused or merily used instead of a local variable. The handlers which need the irq argument can retrieve the irq number from the irq descriptor.
