MIPS: Loongson: Naming style cleanup and rework

2015-06-21T19:53:59Z

Currently, code of Loongson-2/3 is under loongson directory and code of Loongson-1 is under loongson1 directory. Besides, there are Kconfig options such as MACH_LOONGSON and MACH_LOONGSON1. This naming style is very ugly and confusing. Since Loongson-2/3 are both 64-bit general- purpose CPU while Loongson-1 is 32-bit SoC, we rename both file names and Kconfig symbols from loongson/loongson1 to loongson64/loongson32.

MIPS: Loongson-3: Add RS780/SBX00 HPET support

2014-11-24T06:45:02Z

CPUFreq driver need external timer, so add hpet at first. In Loongson 3, only Core-0 can receive external interrupt. As a result, timekeeping cannot absolutely use HPET timer. We use a hybrid solution: Core-0 use HPET as its clock event device, but other cores still use MIPS; clock source is global and doesn't need interrupt, so use HPET.

MIPS: Whitespace cleanup.

Having received another series of whitespace patches I decided to do this once and for all rather than dealing with this kind of patches trickling in forever. Signed-off-by: Ralf Baechle

MIPS: Lemote 2F: Add cs5536 MFGPT timer support

2009-12-17T01:57:19Z

CPUFreq support for Loongson 2F requires an external timer. Because the frequency of the MIPS Timer is related to the CPU frequency which itself is variable another timer of constant frequency is required. Export the mfgpt0 counter disable / enable operations for the coming suspend support to suspend / resume the timer.

loongson: fix cut-and-paste mis-merge

2009-09-20T22:57:28Z

Ingo points out that I screwed up when merging the 'timers-for-linus' branch in commit a03fdb7612874834d6847107198712d18b5242c7. A bit too much copy-and-pasting caused the end result to have an extraneous 'return' in the middle of an expression. That was obviously bogus. Blush.

MIPS: Loongson: Split common loongson source code out

2009-09-17T18:07:47Z

To share common loongson source code between all of the loongson-based machines. there is a need to split it out of the fuloong-2e/ directory. at the same time, other according tuning is needed. the machine-specific parts are defined as macros in relative header file, pci.h, mem.h, machine.h.
