2011-03-11omap2+: mux: Remove the use of IDLE flagR Sricharan
Currently OMAP_DEVICE_PAD_IDLE flag is used to mux pins dynamically. This can be simplified by using the enabled state variable of each pad. This also fixes the issue of the static pads not getting muxed after idling and disable/enable state transitions.

and fix overflow. If we have a guest that asked for: memory=1024 maxmem=2048 Which means we want 1GB now, and create pagetables so that we can expand up to 2GB, we would have this E820 layout: [ 0.000000] BIOS-provided physical RAM map: [ 0.000000] Xen: 0000000000000000 - 00000000000a0000 (usable) [ 0.000000] Xen: 00000000000a0000 - 0000000000100000 (reserved) [ 0.000000] Xen: 0000000000100000 - 0000000080800000 (usable) Due to patch: "xen/setup: Inhibit resource API from using System RAM E820 gaps as PCI mem gaps." we would mark the memory past the 1GB mark as unusuable resulting in: [ 0.000000] BIOS-provided physical RAM map: [ 0.000000] Xen: 0000000000000000 - 00000000000a0000 (usable) [ 0.000000] Xen: 00000000000a0000 - 0000000000100000 (reserved) [ 0.000000] Xen: 0000000000100000 - 0000000040000000 (usable) [ 0.000000] Xen: 0000000040000000 - 0000000080800000 (unusable) which meant that we could not balloon up anymore. We could balloon the guest down. The fix is to run the code introduced by the above mentioned patch only for the initial domain. We will have to revisit this once we start introducing a modified E820 for PCI passthrough so that we can utilize the P2M identity code. We also fix an overflow by having UL instead of ULL on 32-bit machines. [v2: Ian pointed to the overflow issue] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
2011-03-11perf: add OMAP support for the new power eventsJean Pihet
The patch adds the new power management trace points for the OMAP architecture. The trace points are for: - default idle handler. Since the cpuidle framework is instrumented in the generic way there is no need to add trace points in the OMAP specific cpuidle handler; - SoC clocks changes (enable, disable, set_rate), - power domain states: the desired target state and -if different- the actually hit state. Because of the generic nature of the changes, OMAP3 and OMAP4 are supported. Tested on OMAP3 with suspend/resume, cpuidle, basic DVFS.

2011-03-11OMAP: DSS2: Have separate irq handlers for DISPC and DSIarchit taneja
Currently, the core DSS platform device requests for an irq line for OMAP2 and OMAP3. Make DISPC and DSI platform devices request for a shared IRQ line. On OMAP3, the logical OR of DSI and DISPC interrupt lines goes to the MPU. There is a register DSS_IRQSTATUS which tells if the interrupt came from DISPC or DSI. On OMAP2, there is no DSI, only DISPC interrupts goto the MPU. There is no DSS_IRQSTATUS register. Hence, it makes more sense to have separate irq handlers corresponding to the DSS sub modules instead of having a common handler. Since on OMAP3 the logical OR of the lines goes to MPU, the irq line is shared among the IRQ handlers. The hwmod irq info has been removed for DSS to DISPC and DSI for OMAP2 and OMAP3 hwmod databases. The Probes of DISPC and DSI now request for irq handlers.

So the device name is changed from omapdss to omapdss_dss in 2420, 2430, 3xxx clock database files. Now the core driver "omapdss" only takes care of panel registration with the custom bus. core driver also uses the clk_enable() / clk_disable() APIs exposed by DSS for clock management.

2011-03-11futex: Sanitize cmpxchg_futex_value_locked APIMichel Lespinasse
The cmpxchg_futex_value_locked API was funny in that it returned either the original, user-exposed futex value OR an error code such as -EFAULT. This was confusing at best, and could be a source of livelocks in places that retry the cmpxchg_futex_value_locked after trying to fix the issue by running fault_in_user_writeable(). This change makes the cmpxchg_futex_value_locked API more similar to the get_futex_value_locked one, returning an error code and updating the original value through a reference argument.

2011-03-11arm: tcc8k: Fix bus clock calculationOskar Schirmer
There are two dividers used to derive bus clock from system clock: system clock is divided by SCKDIV+1, then by BCKDIV+1. SCKDIV divider has been ignored up to now, which is no problem as long as it is 0. Take SCKDIV into account for bus clock calculation.

2011-03-11arm: tcc8k: Fix indent, coding syleOskar Schirmer
Remove double definition of ACLKUSBH, change parameter name in root_clk_disable, as there is no reason to have a different name than in root_clk_enable. No functional change.

2011-03-11arm: tcc8k: Avoid reading clock register twiceOskar Schirmer
There is no reason why in case of PLL2 the configuration register should be read twice, while for PLL0/1 using the value previously read is used. Do the same for PLL2. Signed-off-by: Oskar Schirmer <oskar@linutronix.de> Cc: bigeasy@linutronix.de Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-03-11arm: tcc8k: Fix clock rate calculationHans J. Koch
The calculation of the best divider value for a requested clock rate always returned a value that was slightly too large. It was also not protected against possible divisions by zero. Request for very low, but non zero rates would cause the ACLK divisor field to overflow. Catch this situation by using the maximum value. The internal function aclk_set_rate() calculates the correct divider value, but doesn't write it back to the register. Add the write back. Signed-off-by: Hans J.

2011-03-11arm: tcc8k: Choose PLL settings conforming to board layoutOskar Schirmer
The evaluation board is driven with 1.2V core voltage, so system clock must not exceed 192 MHz, bus clock must not exceed 110 MHz. Choose appropriate values and set DTCMWAIT accordingly. Adapt UART setting to avoid console log interruption and wait for the specified locking time of 300us to pass.
