2015-06-23Merge branch 'for-linus-clk' of git://ftp.arm.linux.org.uk/~rmk/linux-armLinus Torvalds1-1/+1
Pull clkdev updates from Russell King: "This series addresses some breakage in clkdev caused by a previous patch set from the clk tree which introduced per-user clk structures. This basically renamed the existing 'struct clk' to 'struct clk_hw', and introduced a new 'struct clk'. This change will break anyone using clk_add_alias() with the common clk code enabled. Thankfully, the intersection of users of clk_add_alias() and those using the common clk code is practically zero, but this is something which should be fixed to keep the code sane. The problem is that clk_add_alias() does this: r = clk_get(...); l = clkdev_alloc(r, ...); clk_put(...); which causes the alias to store a pointer to 'r', which has been freed. The original patch set tried to work around this problem incorrectly - at clk_get() time, it tried to convert the struct clk to a struct clk_hw, and then creating a new struct clk from that. Clearly, if the original struct clk has been freed, then we have a use-after-free bug. We have other places in the tree which do something similar, so this series also addresses those locations too. This series addresses this problem by converting clkdev to store and use the clk_hw pointer. This allows clk_get() to only have to create it's per-user struct clk from the clk_hw. We can also get to the desired clk_hw at clk_add_alias() or clk lookup creation time, when the struct clk is "alive". We also perform some cleanups of the code: - replacing looped calls to clkdev_add() with clkdev_add_table() - replacing open-coded lookup allocation (which should have been using clkdev_alloc()) and subsequent clkdev_add() with clkdev_create() - replacing open-coded clk_add_alias() with clk_add_alias()" * 'for-linus-clk' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: clk: s2mps11: use clkdev_create() ASoC: migor: use clkdev_create() ARM: omap2: use clkdev_add_alias() ARM: omap2: use clkdev_create() ARM: orion: use clkdev_create() ARM: lpc32xx: convert to use clkdev_add_table() SH: use clkdev_add_table() clkdev: add clkdev_create() helper clkdev: const-ify connection id to clk_add_alias() clkdev: get rid of redundant clk_add_alias() prototype in linux/clk.h clkdev: drop __init from clkdev_add_table() clk: update clk API documentation to clarify clk_round_rate() clkdev: use clk_hw internally
2015-05-21ARM: OMAP1: Fix section mismatch warnings for omap_cfg_regTony Lindgren1-4/+4

2015-05-21ARM: OMAP1: Fix randconfig builds if ARCH_OMAP15XX not selectedTony Lindgren7-1/+12
With the omap1 SPARSE_IRQ changes mach/irqs.h is no longer automatically included. Turns out now we rely on ARCH_OMAP15XX including hardware.h from memory.h, so without ARCH_OMAP15XX we get build failures. As we have legacy drivers still relying on these indirect includes, let's not add more mach includes to the drivers. Those have to be removed anyways for multiplatform support. Let's fix up mach-omap1 to include soc.h where cpu_is_omap checks are done, and common.h for board-*.c files. But let's keep the indirect memory.h include for now to avoid unnecessary churn in the drivers. Signed-off-by: Tony Lindgren <tony@atomide.com>
2015-05-20ARM: OMAP1: Change interrupt numbering for sparse IRQTony Lindgren7-71/+70
Change interrupt numbering for sparse IRQ. We do this using a fixed offset until we can drop irqs.h once all it's users have been updated. Note that this depends on the GPIO fix for the MPUIO IRQs "gpio: omap: Fix regression for MPUIO interrupts". Also note that this patch adds some extra irq alloc warnings that will go away when we stop calling irq_alloc_descs in gpio-omap.c with a follow-up patch.

2015-01-21ARM: 8271/1: omap1: Migrate debug_ll macros to use 8250.SDaniel Thompson1-101/+0
The omap1's debug-macro.S is similar to the generic 8250 code. Compared to the 8520 code the omap1 macro automatically determines what UART to use based on breadcrumbs left by the bootloader and automatically copes with the eccentric register layout on OMAP7XX. This patch drops both these features and relies instead on the generic 8250 macros: 1. Dropping support for the bootloader breadcrumbs is identical to the way the migration was handled for OMAP2 (see 808b7e07464d...). 2. Support for OMAP7XX still exists but it must be configured by hand (DEBUG_OMAP7XXUART1/2/3) rather than handled at runtime.

2014-07-29ARM: 8113/1: remove remaining definitions of PLAT_PHYS_OFFSET from ↵Uwe Kleine-König1-5/+0
<mach/memory.h> The platforms selecting NEED_MACH_MEMORY_H defined the start address of their physical memory in the respective <mach/memory.h>. With ARM_PATCH_PHYS_VIRT=y (which is quite common today) this is useless though because the definition isn't used but determined dynamically. So remove the definitions from all <mach/memory.h> and provide the Kconfig symbol PHYS_OFFSET with the respective defaults in case ARM_PATCH_PHYS_VIRT isn't enabled. This allows to drop the dependency of PHYS_OFFSET on !NEED_MACH_MEMORY_H which prevents compiling an integrator nommu-kernel. (CONFIG_PAGE_OFFSET which has "default PHYS_OFFSET if !MMU" expanded to "0x" because CONFIG_PHYS_OFFSET doesn't exist as INTEGRATOR selects NEED_MACH_MEMORY_H.)

2014-03-21ARM: omap1: don't rely on tps65010Arnd Bergmann2-0/+6
The code for h2 and osk implicitly assumes that the tps65010 driver is built-in, in order to perform the initial regulator setup. This is fine for most real uses, but it does get into the way of build testing with 'make randconfig', since we don't want platforms to implicitly select device drivers and subsystems such as I2C. This patch by contrast changes the board files to not call into the tps65010 driver when that is not built-in, allowing us to build all configurations including some that will not work properly on this hardware.

next/cleanup This cleanup series gets rid of <mach/timex.h> for platforms not using ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since 387798b (ARM: initial multiplatform support).) To make this work some code out of arch/arm needed to be adapted. The respective changes got acks by their maintainers to be taken via armsoc (with Andrew Morton substituting for Alessandro Zummo as rtc maintainer). Compared to the previous pull request there was another patch added that fixes a (non-critical) regression on ixp4xx. Olof Johansson asked to not squash this fix into the original commit to save him from the need to reverify the series. * tag 'dropmachtimexh-v2' of git://git.pengutronix.de/git/ukl/linux: ARM: ixp4xx: fix timer latch calculation ARM: drop <mach/timex.h> for !ARCH_MULTIPLATFORM, too ARM: rpc: stop using <mach/timex.h> ARM: ixp4xx: stop using <mach/timex.h> input: ixp4xx-beeper: don't use symbols from <mach/timex.h> ARM: at91: don't use <mach/timex.h> ARM: ep93xx: stop using mach/timex.h ARM: mmp: stop using mach/timex.h ARM: netx: stop using mach/timex.h ARM: sa1100: stop using mach/timex.h clocksource: sirf/marco+prima2: drop usage of CLOCK_TICK_RATE rtc: pxa: drop unused #define TIMER_FREQ rtc: at91sam9: include <mach/hardware.h> explicitly ARM/serial: at91: switch atmel serial to use gpiolib Signed-off-by: Olof Johansson <olof@lixom.net>
