ARM: mach-omap2: board-generic: fix undefined symbol
Since dra7 reuses the function 'omap5_realtime_timer_init' in arch/arm/mach-omap2/board-generic.c as timer init function, it has to be built for this SoC as well. Signed-off-by: Simon Barth <Simon.Pe.Barth@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com> |

ARM: SoC platform changes for 3.12
This branch contains mostly additions and changes to platform enablement
and SoC-level drivers. Since there's sometimes a dependency on device-tree
changes, there's also a fair amount of those in this branch.
Pieces worth mentioning are:
- Mbus driver for Marvell platforms, allowing kernel configuration
and resource allocation of on-chip peripherals.
- Enablement of the mbus infrastructure from Marvell PCI-e drivers.
- Preparation of MSI support for Marvell platforms.
- Addition of new PCI-e host controller driver for Tegra platforms
- Some churn caused by sharing of macro names between i.MX 6Q and 6DL
platforms in the device tree sources and header files.
- Various suspend/PM updates for Tegra, including LP1 support.
- Versatile Express support for MCPM, part of big little support.
- Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7)
- OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
The code that touches other architectures are patches moving
MSI arch-specific functions over to weak symbols and removal of
ARCH_SUPPORTS_MSI, acked by PCI maintainers.

ARM: SoC cleanups for 3.12
This branch contains code cleanups, moves and removals for 3.12.
There's a large number of various cleanups, and a nice net removal of
13500 lines of code.
Highlights worth mentioning are:
- A series of patches from Stephen Boyd removing the ARM local timer API.
- Move of Qualcomm MSM IOMMU code to drivers/iommu.
- Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM driver
and switching over to the drivers/pwm one.
- Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).
There's also a move of a header file out of include/linux/i2c/ to
platform_data, where it really belongs. It touches mostly ARM platform
code for include changes so we took it through our tree.

ARM: OMAP2+: fix wrong address when loading PRM_FRAC_INCREMENTOR_DENUMERATOR_RELOAD
The denominator should be load from INCREMENTOR_DENUMERATOR_RELOAD_OFFSET rather than INCREMENTER_NUMERATOR_OFFSET. This is more likely a typo, since INCREMENTER_DENUMERATOR_RELOAD[23:17] is reserved. It seems that it won't make much trouble without this fix, because the useful [11:0] bits are mask and set the right value. Anyway, reading from a right address is better choice.

- A handful of build and warning fixes from Arnd
- A collection of OMAP fixes
- defconfig updates to make the default configs more useful for real use

And a couple of other small fixes. Some of these have been recently
applied but it's normally how we deal with fixes, with less bake time
in -next needed.

of_property_read_string_index(...,&oh_name) in omap_dm_timer_init_one does not alter the value of 'oh_name' even if the relevant function fails and as 'oh_name' in stack may have a non-zero value, it would be misunderstood by timer code that DT has specified "ti,hwmod" property for timer.

ARM: arm-soc: late cleanups
These are cleanups and smaller changes that either depend on earlier
feature branches or came in late during the development cycle.
We normally try to get all cleanups early, so these are the exceptions:
- A follow-up on the clocksource reworks, hopefully the last time
we need to merge clocksource subsystem changes through arm-soc.
A first set of patches was part of the original 3.10 arm-soc cleanup
series because of interdependencies with timer drivers now moved out
of arch/arm.
- Migrating the SPEAr13xx platform away from using auxdata for DMA
channel descriptions towards using information in device tree,
based on the earlier SPEAr multiplatform series
- A few follow-ups on the Atmel SAMA5 support and other changes
for Atmel at91 based on the larger at91 reworks.
- Moving the armada irqchip implementation to drivers/irqchip
- Several OMAP cleanups following up on the larger series already
merged in 3.10.

- A follow-up on the clocksource reworks, hopefully the last time we
need to merge clocksource subsystem changes through arm-soc.
A first set of patches was part of the original 3.10 arm-soc
cleanup series because of interdependencies with timer drivers now
moved out of arch/arm.
- Migrating the SPEAr13xx platform away from using auxdata for DMA
channel descriptions towards using information in device tree,
based on the earlier SPEAr multiplatform series
- A few follow-ups on the Atmel SAMA5 support and other changes for
Atmel at91 based on the larger at91 reworks.
- Moving the armada irqchip implementation to drivers/irqchip
- Several OMAP cleanups following up on the larger series already
merged in 3.10."

This converts arm and arm64 to use CLKSRC_OF DT based initialization for the arch timer. A new function arch_timer_arch_init is added to allow for arch specific setup.

ARM: OMAP3: Update clocksource timer selection
When booting with device-tree for OMAP3 and AM335x devices and a gptimer is used as the clocksource (which is always the case for AM335x), a gptimer located in a power domain that is not always-on is selected. Ideally we should use a gptimer for clocksource that is located in a power domain that is always on (such as the wake-up domain) so that time can be maintained during a kernel suspend without keeping on additional power domains unnecessarily. In order to fix this so that we can select a gptimer located in a power domain that is always-on, the following changes were made ... 1. Currently, only when selecting a gptimer to use for a clockevent timer, do we pass a timer property that can be used to select a specific gptimer. Change this so that we can pass a property when selecting a gptimer to use for a clocksource timer too. 2. Currently, when selecting either a gptimer to use for a clockevent timer or a clocksource timer and no timer property is passed, then the first available timer is selected regardless of the properties it has. Change this so that if no properties are passed, then a timer that does not have additional features (such as always-on, dsp-irq, pwm, and secure) is selected. For OMAP3 and AM335x devices that use a gptimer for clocksource, change the selection of the gptimer so that by default the gptimer located in the always-on power domain is used for clocksource instead of clockevents. Please note that using a gptimer for both clocksource and clockevents can have a system power impact during idle. The reason being is that OMAP and AMxxx devices typically only have one gptimer in a power domain that is always-on. Therefore when the kernel is idle both the clocksource and clockevent timers will be active and this will keep additional power domains on. During kernel suspend, only the clocksource timer is active and therefore, it is better to use a gptimer in a power domain that is always-on for clocksource.

ARM: OMAP2+: Simplify system timers definitions
There is a lot of redundancy in the definitions for the various system timers for OMAP2+ devices. For example, the omap3_am33xx_gptimer_timer_init() function is the same as the omap3_gp_gptimer_timer_init() function and the function omap4_sync32k_timer_init() can be re-used for OMAP5 devices. Therefore, consolidate the definitions to simplify the code.

ARM: OMAP2+: Remove hard-coded test on timer ID
Currently, when configuring the clock-events and clock-source timers for OMAP2+ devices, we check whether the timer ID is 12 before attempting to set the parent clock for the timer. This test was added for OMAP3 general purpose devices (no security features enabled) that a 12th timer available but unlike the other timers only has a single functional clock source. Calling clk_set_parent() for this 12th timer would always return an error because there is only one choice for a parent clock. Therefore, this hard-coded timer ID test was added. To avoid this timer ID test, simply check to see if the timer's current parent clock is the desired parent clock and only call clk_set_parent() if this is not the case. Also if clk_get() fails, then use PTR_ERR() to return the error code. Signed-off-by: Jon Hunter <jon-hunter@ti.com> Acked-by: Santosh Shilimkar <santosh.shilimkar@ti.com> |

ARM: OMAP2+: Display correct system timer name
Currently on boot, when displaying the name of the gptimer used for clockevents and clocksource timers, the timer ID is shown. However, when booting with device-tree, the timer ID is not used to select a gptimer but a timer property. Hence, it is possible that the timer selected when booting with device-tree does not match the ID shown. Therefore, instead display the HWMOD name of the gptimer and use the HWMOD name as the name of clockevent and clocksource timer (if a gptimer is used).

ARM: OMAP: clocks: Delay clk inits atleast until slab is initialized
clk inits on OMAP happen quite early, even before slab is available. The dependency comes from the fact that the timer init code starts to use clocks and hwmod and we need clocks to be initialized by then. There are various problems doing clk inits this early, one is, not being able to do dynamic clk registrations and hence the dependency on clk-private.h.

It was a know issue, that slab allocations would fail when common clock core tries to cache parent pointers for mux clocks on OMAP, and hence a patch 'clk: Allow late cache allocation for clk->parents, commit 7975059d' was added to work this problem around. A BUG() within kmalloc() with CONFIG_DEBUG_SLAB enabled was completely overlooked causing this regression. More details on the issue reported can be found here, http://www.mail-archive.com/linux-omap@vger.kernel.org/msg85932.html With all these issues around clk inits happening way too early, it makes sense to at least move them to a point where dynamic memory allocations are possible. So move them to a point just before the timer code starts using clocks and hwmod. This should at least pave way for clk inits on OMAP moving to dynamic clock registrations instead of using the static macros defined in clk-private.h. The issue with kernel panic while CONFIG_DEBUG_SLAB is enabled was reported by Piotr Haber and Tony Lindgren and this patch fixes the reported issue as well.

ARM: OMAP: use consistent error checking
Consistently check errors using the usual method used in the kernel
for much of its history. For instance:
int gpmc_cs_set_timings(int cs, const struct gpmc_timings *t)
{
int div;
div = gpmc_calc_divider(t->sync_clk);
if (div < 0)
return div;
static int gpmc_set_async_mode(int cs, struct gpmc_timings *t)
{
...
return gpmc_cs_set_timings(cs, t);
.....
ret = gpmc_set_async_mode(gpmc_onenand_data->cs, &t);
if (IS_ERR_VALUE(ret))
return ret;
So, gpmc_cs_set_timings() thinks any negative return value is an error,
but where we check that in higher levels, only a limited range are
errors...
There is only _one_ use of IS_ERR_VALUE() in arch/arm which is really
appropriate, and that is in arch/arm/include/asm/syscall.h:
static inline long syscall_get_error(struct task_struct *task,
struct pt_regs *regs)
{
unsigned long error = regs->ARM_r0;
return IS_ERR_VALUE(error) ? error : 0;
}
because this function really does have to differentiate between error
return values and addresses which look like negative numbers (eg, from
mmap()).
So, here's a patch to remove them from OMAP, except for the above.

arm-soc: cleanups
A large number of cleanups, all over the platforms. This is dominated largely by the Samsung platforms (s3c, s5p, exynos) and a few of the others moving code out of arch/arm into more appropriate subsystems. The clocksource and irqchip drivers are now abstracted to the point where platforms that are already cleaned up do not need to even specify the driver they use, it can all get configured from the device tree as we do for normal device drivers. The clocksource changes basically touch every single platform in the process. We further clean up the use of platform specific header files here, with the goal of turning more of the platforms over to being "multiplatform" enabled, which implies that they cannot expose their headers to architecture independent code any more. It is expected that no functional changes are part of the cleanup. The overall reduction in total code lines is mostly the result of removing broken and obsolete code. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUSUyKmCrR//JCVInAQIN8RAAnb/uPytmlMjn5yCksF4Mvb/FVbn/TVwz KRIGpCHOzyKK1q7pM8NRUVWfjW2SZqbXJFqx6zBGKSlDPvFTOhsLyyupU+Tnyu5W IX4eIUBwb+a6H7XDHw0X2YI8uHzi5RNLhne0A1QyDKcnuHs1LDAttXnJHaK4Ap6Y NN2YFt3l3ld7DXWXJtMsw5v8lC10aeIFGTvXefaPDAdeMLivmI57qEUMDXknNr7W Odz/Rc0/cw3BNBVl/zNHA0jw7FOjKAymCYYNUa4xDCJEr+JnIRTqizd0N/YIIC7x aA2xjJ3oKUFyF51yiJE6nFuTyJznhwtehc+uiMOSIkjrPLym52LEHmd7G5Yqlmjz oiei09qBb870q3lGxwfht9iaeIwYgQFYGfD0yW5QWArCO5pxhtCPLPH7YZNZtcQd ZJRSGGqT/ljBz3bm0K9OLESeeTTN7+Nxvtpiz/CD+Piegz0gWJzDYJRTzkJ3UWpA WTVhVQdWUeX2JrNkgM7Z3Tu8iXOe+LIEs7kVXGJZSREmIIZiRvR36UrODZtAkp9I 7YQ+srX/uaR832pgK0RrHK0zY0psU6MmIvhYxJZFbx7keiPA9eH6drb0x7tGqcUD FzEUzvcZvyqppndfBi+R60H/YKAhJDEXdwxzo6dyCpPQaW1T9GnzIqXuE1zin+Aw X7Y8YywMbHI= =DvgJ -----END PGP SIGNATURE----- Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Arnd Bergmann: "A large number of cleanups, all over the platforms.

ARM: OMAP2+: omap_device: remove obsolete pm_lats and early_device code
Remove now-obsolete code from arch/arm/mach-omap2/omap_device.c. This mostly consists of removing the first attempt at device PM latency handling. This was never really used, has been replaced by the common dev_pm_qos code, and needs to go away as part of the DT conversion. Also, the early platform_device creation code has been removed, as it appears to be unused. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Kevin Hilman <khilman@deeprootsystems.com> |

ARM: OMAP2+: DT node Timer iteration fix
The iterator correctly handles of_node_put() calls. Remove it before continue'ing the loop.
