Add support for NXP's LPC18xx (Cortex-M3) and LPC43xx (Cortex-M4) SoCs. These SoCs are NXP's high preformance MCU line and can run at clock speeds up to 180 MHz for LPC18xx and 204 MHz for LPC43xx. LPC43xx is more or less a LPC18xx with a Cortex-M4F core and a few extra peripherals. The LPC43xx series also features one or two Cortex-M0 cores that can be used to offload the main M4 core.

Merge "pxa changes for v4.2 cycle" from Robert Jarzmik: The main and only feature is the conversion of all pxa variants to clock framework. This encompasses pxa25x, pxa27x and pxa3xx, for all boards. This should be a disruptive cycle in the normally quiet pxa history, as the change can break any platform, and the test were performed on only 4 boards (lubbock, zylonite, mioa701, cm-x300). * tag 'pxa-for-4.2' of https://github.com/rjarzmik/linux: ARM: pxa: Constify irq_domain_ops ARM: pxa: Transition pxa25x, pxa27x, pxa3xx to clk framework ARM: pxa: convert eseries to clock framework ARM: pxa: Transition pxa25x and pxa27x to clk framework ARM: pxa: pxa27x skip default device initialization with DT clk: pxa: add missing pxa27x clocks for Irda and sa1100-rtc ARM: pxa: move gpio11 clock to board files ARM: pxa: change clocks init sequence

Since the WDT is what's used to drive restart and power off, it makes more sense to keep it there, where the regs are already mapped and definitions for them provided. Note that this means you may need to add CONFIG_BCM2835_WDT to retain functionality of your kernel. Signed-off-by:

The only thing we were using this 16MB mapping of IO peripherals for was the uart's early debug mapping. If we just drop the map_io hook, the kernel will call debug_ll_io_init() for us, which maps the single page needed for the device. Signed-off-by:

Transition the PXA25x, PXA27x and PXA3xx CPUs to the clock framework. This transition still enables legacy platforms to run without device tree as before, ie relying on platform data encoded in board specific files.

Transition the PXA25x and PXA27x CPUs to the clock framework. This transition still enables legacy platforms to run without device tree as before, ie relying on platform data encoded in board specific files. The transition breaks the previous clocks activation of pin control (gpio11 and gpio12). Machine files should be amended to take that into account. This is the last step of clock framework transition for pxa25x and pxa27x, leaving only pxa3xx for further work. Reviewed-by:

Since pxa clocks were ported to the clock framework, an ordering issue appears between clocks and clocksource initialization. As a consequence, the pxa timer clock cannot be acquired in pxa_timer, and is disabled by clock framework because it is "unused". The ordering issue is that in the kernel boot sequence : start_kernel() ... time_init() -> pxa_timer() -> here the clocksource is initialized ... rest_init() kernel_init() initcalls -> here the clocks are initialized In the current sequence, the clocks are initialized way after pxa_timer, which cannot acquire the OSTIMER0 clock. To solve this issue, the clocks initialization is moved to pxa_timer(), so that clocks are initialized before clocksource for non device-tree. For device-tree, the standard arm time_init() will take care of the ordering. Reviewed-by:

Since commit 844b03f2 we make sure that after vblank irq off, we return the last valid (vblank count, vblank timestamp) pair to clients, e.g., during modesets, which is good. An overlooked side effect of that commit for kms drivers without support for precise vblank timestamping is that at vblank irq enable, when we update the vblank counter from the hw counter, we can't update the corresponding vblank timestamp, so now we have a totally mismatched timestamp for the new count to confuse clients. Restore old client visible behaviour from before Linux 3.17, but zero out the timestamp at vblank counter update (instead of disable as in original implementation) if we can't generate a meaningful timestamp immediately for the new vblank counter. This will fix this regression, so callers know they need to retry again later if they need a valid timestamp, but at the same time preserves the improvements made in the commit mentioned above.
