| * ARM: S3C64XX: Fix possible clock look in EPLL and MPLL clock chainsBen Dooks2010-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a possibility of a loop happening in the PLL output clock chain on the S3C64XX series. clk_mpll's parent was set to be clk_mout_mpll, but this is fed from clk_fout_epll (which is also clk_mpll). clk_mpll is meant to be the output from the MPLL, and clk_mout_mpll is a seperate clock derived from the mux of clk_mpll and clk_fin_mpll and thus should be considered a seperate clock. Anything using clk_mpll directly really should not be relying on this being the clock that is eventually routed to a peripheral, so remove the loop and ensure that the clocks accurately represent the clock chain in the device. The clk_mpll is not being used outside of the s3c6400-clock.c code, so this change should not break anything else. Do the same for the EPLL. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

With this change, we can run into a situation where an irq cleanup interrupt on a cpu can cleanup the vector mappings associated with multiple irqs, of which one of the irq's migration might be still in progress. As such when that irq hits the old cpu, we get the "No IRQ handler" messages. Fix this by checking for the irq_cfg's move_in_progress and if the move is still in progress delay the vector cleanup to another irq cleanup interrupt request (which will happen when the irq starts arriving at the new cpu destination).

Although this is against the PCI specification, we can handle it quite easily by allowing drivers to define arbitrary D3 delays for devices known to require extra time for switching power states. Introduce additional field d3_delay in struct pci_dev and use it to store the value of the device's D0->D3 delay, in miliseconds. Make the PCI PM core code use the per-device d3_delay unless pci_pm_d3_delay is greater (in which case the latter is used). [This also allows the driver to specify d3_delay shorter than the 10 ms required by the PCI standard if the device is known to be able to handle that.] Make the sky2 driver set d3_delay to 150 for devices handled by it.

In the event of other errors, we generally want the initiating task to retry the upcall so we set msg.errno to -EAGAIN. An unexpected error code here is a bug however, so BUG() in that case.

Instead, use the G4X DPLL calculator, which does a better job at it. So we use the intel_g4x_find_best_pll to calculate the DPLL for CRT/HDMI/LVDS on ironlake. At the same time to consider the dpll setting for display port, we add the display port DPLL limit on ironlake, which will directly use the function of intel_find_pll_ironlake_dp to get the corresponding dpll setting.
