2021-01-07MIPS: Remove empty prom_free_prom_memory functionsThomas Bogendoerfer
Most of the prom_free_prom_memory functions are empty. With a new weak prom_free_prom_memory() we can remove all of them. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Acked-by: Florian Fainelli <f.fainelli@gmail.com>
2020-10-12MIPS: replace add_memory_region with memblockThomas Bogendoerfer
add_memory_region was the old interface for registering memory and was already changed to used memblock internaly. Replace it by directly calling memblock functions. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2020-03-05MIPS: Replace setup_irq() by request_irq()afzal mohammed
request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq(). remove_irq() has been replaced by free_irq() as well. There were build error's during previous version, couple of which was reported by kbuild test robot <lkp@intel.com> of which one was reported by Thomas Bogendoerfer <tsbogend@alpha.franken.de> as well. There were a few more issues including build errors, those also have been fixed.

2019-11-11MIPS: Loongson{2ef, 32, 64} convert to generic fw cmdlineJiaxun Yang
All of Loongson firmwares are passing boot cmdline/env in the manner of YAMON/PMON. Thus we can remove duplicated cmdline initialize code and convert to generic fw method.

2017-04-14MIPS: clockevent drivers: Set ->min_delta_ticks and ->max_delta_ticksNicolai Stange
In preparation for making the clockevents core NTP correction aware, all clockevent device drivers must set ->min_delta_ticks and ->max_delta_ticks rather than ->min_delta_ns and ->max_delta_ns: a clockevent device's rate is going to change dynamically and thus, the ratio of ns to ticks ceases to stay invariant. Make the MIPS arch's clockevent drivers initialize these fields properly. This patch alone doesn't introduce any change in functionality as the clockevents core still looks exclusively at the (untouched) ->min_delta_ns and ->max_delta_ns. As soon as this has changed, a followup patch will purge the initialization of ->min_delta_ns and ->max_delta_ns from these drivers.

2015-06-21MIPS: Loongson: Naming style cleanup and reworkHuacai Chen
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.
