Commit 6e6aac75 "ARM: EXYNOS: Migrate clock support to common clock framework" from Thomas Abraham removed the Exynos5 specific register definitions as they were unused at the time, but the cpufreq driver actually still uses them.

2013-04-20irqchip: exynos: pass irq_base from platformArnd Bergmann2-2/+3
The platform code knows the IRQ base, while the irqchip driver should really not. This is a littly hacky because we still hardwire the IRQ base to 160 for the combiner in the DT case, when we should really use -1. Removing that line will cause a linear IRQ domain to be use, as we should. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Thomas Gleixner <tglx@linutronix.de>
2013-04-20irqchip: exynos: pass max combiner number to combiner_initArnd Bergmann2-2/+16
We can find out the number of combined IRQs from the device tree, but in case of ATAGS boot, the driver currently uses hardcoded values based on the SoC type. We can't do that in general for a multiplatform kernel, so let's instead pass this information from platform code directly in case of ATAGS boot.

2013-04-20clocksource: exynos_mct: remove platform header dependencyArnd Bergmann2-2/+2
For the non-DT case, the mct_init() function requires access to a couple of platform specific constants, but cannot include the header files in case we are building for multiplatform. This changes the interface to the platform so we pass all the necessary data as arguments to mct_init.

2013-04-20clk: exynos: prepare for multiplatformArnd Bergmann2-2/+2
The new common clock drivers for exynos are using compile time constants and soc_is_exynos* macros to provide backwards compatibility for pre-DT systems, which is not possible with multiplatform kernels. This moves all the necessary information back into platform code and removes the mach/* header inclusions. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Mike Turquette <mturquette@linaro.org>

2013-04-19Merge branch 'samsung/exynos-multiplatform' into next/multiplatformArnd Bergmann12-47/+56
These patches get us closer to adding multiplatform support on the Exynos platform, they are part of a longer series of patches. This would get all the simple stuff out of the way, and I don't think there is a big risk of introducing regressions with these. A lot of the other patches have already been merged into subsystem trees. After this series in in arm-soc, what is left comes down to * The ASoC conversion to dmaengine won't make it unless someone who knows that code better steps up to do it right away. This means that we won't have audio in a 3.10 multiplatform kernel on Exynos, but it will still work for users that don't enable multiplatform. * The irqchip (combiner), clk and clksource patches are all based on top of other changesets we pulled in from your trees, so I would not make them part of the next/multiplatform branch. We can apply them on top of the next/drivers branch once they are tested successfully. * A trivial patch is needed in the end to actually make CONFIG_ARCH_EXYNOS visible in multiplatform configurations. We will do that as a separate patch once everything else is there. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2013-04-19ARM: exynos: enable multiplatform supportArnd Bergmann3-6/+30
This makes it possible to enable the exynos platform as part of a multiplatform kernel, in addition to keeping the single-platform exynos support. The multiplatform variant has a number of limitations at the moment: * It only supports DT-enabled machines. This is not a problem in the long run, as non-DT machines for exynos are going away. The main problem here is that the gpio code and the exynos_eint irqchip are not multiplatform capable but still required for ATAGS based boot. * The watchdog driver is still missing a conversion. * sparsemem and memory_holes are currently not supported in multiplatform. The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled for now, as dependent patches are still pending in other subsystem trees. We will enable it once everything comes together.

2013-04-19mmc: sdhci-s3c: remove platform dependenciesArnd Bergmann1-1/+1
plat/regs-sdhci.h is not used anywhere but in the sdhci-s3c driver, so it can become a local file there and all other inclusions removed. plat/sdhci.h is used only to define the platform devices, and with the exception of the platform_data structure not needed by the driver, so we can split out the platform_data definition instead and leave the rest to platform code.

2013-04-19ARM: exynos: move debug-macro.S to include/debug/Arnd Bergmann1-39/+0
The move is necessary to support early debug output on exynos with multiplatform configurations. This implies also moving the plat/debug-macro.S file, but we are leaving the remaining users of that file in place, to avoid adding large numbers of extra configuration options to Kconfig.debug Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2013-04-19ARM: exynos: prepare for sparse IRQArnd Bergmann7-1/+10
When we enable CONFIG_SPARSE_IRQ, we have to set the value of NR_IRQS in the machine_desc for legacy IRQ domains, and any file referring to the number of interrupts or a specific number must include the mach/irqs.h header file explicitly. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2013-04-19ARM: exynos: introduce EXYNOS_ATAGS symbolArnd Bergmann1-0/+15
As a preparation for multiplatform support, this introduces a new Kconfig symbol to split the ATAGS based EXYNOS platforms from the DT based ones. Turning off CONFIG_EXYNOS_ATAGS disables all platforms that are not yet converted to DT, and we can have code that relies on DT checking for this symbol being disabled.

2013-04-09ARM: Push selects for TWD/SCU into machine entriesStephen Boyd1-0/+2
The TWD and SCU configs are selected by default as long as MSM_SCORPIONMP is false and/or MCT is false. Implementing the logic this way certainly saves lines in the Kconfig but it precludes those machines which select MSM_SCORPIONMP or MCT from participating in the single zImage effort because when those machines are combined with other SMP capable machines the TWD and SCU are no longer selected by default. Push the select out to the machine entries so that we can compile these machines together and still select the appropriate configs.

2013-03-22ARM: EXYNOS: drop "select HAVE_SCHED_CLOCK"Paul Bolle1-1/+0
The Kconfig symbol HAVE_SCHED_CLOCK got removed in v3.4, with commit 6905a65879b5 ("ARM: Make the sched_clock framework mandatory"). Drop the last two select statements for that symbol too. They're useless now. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

With device tree support enabled for MCT controller, the staticio-remapping of the MCT controller address space is removed for Exynos5 platforms (which supports only device tree based boot).

2013-03-09ARM: EXYNOS: allow dt based discovery of mct controller using ↵Thomas Abraham10-16/+18
clocksource_of_init Add entries to __clksrc_of_table so that Exynos MCT controller is discoverable using call to clocksource_of_init. With this change, it would be appropriate to rename the function 'exynos4_timer_init' as 'mct_init' since it aptly describes this function. Additionally, the 'init_time' callback of all machine descriptors for exynos platforms that were previously set to 'exynos4_timer_init' are now set to either 'mct_init' or 'clocksource_of_init'.
