| * ARM: zynq: reserve space for jump target in secondary trampolineNathan Lynch2015-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a zero argument to the .word directive in zynq_secondary_trampoline. Without an expression the assembler emits nothing for the .word directive. This makes it so that the intended range is communicated to ioremap and outer_flush_range in zynq_cpun_start; e.g. for LE trampoline_code_size evaluates to 12 now instead of 8. Found by inspection. I'm not aware of any real problem this fixes. Tested by doing on online/offline loop on ZC702.

| * ARM: zynq: Set bit 22 in PL310 AuxCtrl register (6395/1)Thomas Betker2015-07-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is based on the commit 1a8e41cd672f ("ARM: 6395/1: VExpress: Set bit 22 in the PL310 (cache controller) AuxCtlr register") Clearing bit 22 in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption. For Zynq, this fix avoids memory inconsistencies between Gigabit Ethernet controller (GEM) and CPU when DMA_CMA is disabled.

The System Control Processor System (SCPSYS) has several power management related tasks in the system. The tasks include thermal measurement, dynamic voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control. The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power domain control. For now this driver only adds power domain support, the more advanced features are not yet supported. The driver implements the generic PM domain device tree bindings, the first user will most likely be the Mediatek AFE audio driver.

Furthermore, the kerneldoc for of_node_put() explicitly supports passing in a NULL pointer as its argument. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.

This is to prevent any spurious writes from changing the register values. This patch adds optional lock and unlock function pointers to the IP block's hwmod data. These unlock and lock function pointers are called by hwmod code before and after writing sysconfig registers.

Cleanup all the module related references both from the code and in the build. While at it, also relocate a comment around the initcall to avoid a checkpatch strict warning about using a blank line after function/struct/union/enum declarations.
