* ARM: OMAP: remove unused variableArnd Bergmann2013-04-231-3/+1
| | | | | | | | Commit 0583fe478a7 "ARM: convert arm/arm64 arch timer to use CLKSRC_OF init" has left the omap5_realtime_timer_init() function with a stale variable and broken whitespace. This fixes both. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

It should have been sorted out by this merge though.
| * ARM: integrator-cp: convert use CLKSRC_OF for timer initRob Herring2013-04-113-37/+38
| | | | | | | | | | | | | | | | | | | | | | | | Move the integrator-cp timer init to timer-sp.c and use CLKSRC_OF. There is no reason to use the aliases, so drop them from the init code. The integrator-cp timers are mistakenly called sp804 timers in the dts, but in fact they are not sp804 dual timers, but single timers with the same programming model. Fix the dts to reflect this.

With device tree support for MCT controller, it is possible to remove the static remap of the MCT controller address space and do the remap during the initialization of the MCT controller with the physical address obtained from the device tree. So in preparation of adding device tree support for MCT controller, add a new register base address variable that will hold the remapped MCT controller base address and convert all MCT register read/writes to use this new variable as the base address instead of the fixed S5P_VA_SYSTIMER. While at it, the MCT register offset and bit mask definitions are moved into the MCT controller driver file since there are no other consumers of these definitions.

Also the interrupts of the second full interrupt controller on the s3c2416 are really handled now, which was forgotten when adding them. The handling itself does the same as the previous assembler-code in that it tries to get the interrupt offset from the offset register first and if that produces wrong results manually searches for the interrupt bit in the pending register value. It also saves the historic comment which explains the reason behind this. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

This does of course not work when the parent irq sits in the bit 0 of the parent register. This only affects the eint0 interrupt of the s3c2412. To fix this behaviour, check for the presence of a parent_intc in the structure. In an s3c24xx interrupt controller either all interrupts have parent interrupts or none have, so if a parent controller is available the parent_irq value always points to a parent_irq.

The interrupt controller structs always contain an irq_data array with 32 entries and the only possible error could be a parent_irq assignment of >31. As this would point to outside the irq_data array this could contain anything including non-NULL values. Therefore correct this to check the parent_irq value to be in the right range. With the same explanation of a valid interrupt controller always having a full irq_data array, the topmost irq_data check in s3c24xx_irq_map can also go away. Finally the mapping function is only called thru the irq_domain ops, in which case the intc struct is already successfully created, so there is no need to check for it again.

Mike's branch is based on v3.9-rc3, which includes a USB change which causes problems on Tegra. That problem was fixed in v3.9-rc4. Hence, this branch pulls in v3.9-rc4 to ensure bisectability as much as possible. This branch is based on v3.9-rc4, followed by a merge of previous Tegra "soc" pull request, followed by a merge of clk-for-3.10. * tag 'tegra-for-3.10-clk' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra: clk: tegra: fix enum tegra114_clk to match binding clk: tegra: Remove forced clk_enable of uartd ARM: dt: Add references to tegra_car clocks clk: tegra: devicetree match for nvidia,tegra114-car clk: tegra: Implement clocks for Tegra114 ARM: tegra: Define Tegra114 CAR binding clk: tegra: Workaround for Tegra114 MSENC problem clk: tegra: Add flags to tegra_clk_periph() clk: tegra: Add new fields and PLL types for Tegra114 clk: tegra: move from a lock bit idx to a lock mask clk: tegra: Add PLL post divider table clk: tegra: introduce TEGRA_PLL_HAS_LOCK_ENABLE clk: tegra: Add TEGRA_PLL_BYPASS flag clk: tegra: Refactor PLL programming code clk: tegra: provide dummy cpu car ops clk: tegra: defer application of init table clk: tegra: Fix cdev1 and cdev2 IDs clk: tegra: Make gr2d and gr3d clocks children of pll_c clk: tegra: Export peripheral reset functions clk: tegra: Fix periph_clk_to_bit macro Signed-off-by: Arnd Bergmann <arnd@arndb.de>

It can't be initialized earlier, since dynamic memory usage is required. It can't be initialized later, since the .init_timer() hook needs the clocks initialized. However, at this time, udelay() doesn't work. The Tegra clock initialization table may enable some PLLs. Enabling a PLL may require usage of udelay(). Hence, this can't happen right when the clock driver is initialized. To solve this, separate the clock driver initialization from the clock table processing, so they can execute at separate times.
