2018-07-17MIPS: loongson64: cs5536: Fix PCI_OHCI_INT_REG readsPaul Burton1-1/+1
The PCI_OHCI_INT_REG case in pci_ohci_read_reg() contains the following if statement: if ((lo & 0x00000f00) == CS5536_USB_INTR) CS5536_USB_INTR expands to the constant 11, which gives us the following condition which can never evaluate true: if ((lo & 0xf00) == 11) At least when using GCC 8.1.0 this falls foul of the tautoligcal-compare warning, and since the code is built with the -Werror flag the build fails. Fix this by shifting lo right by 8 bits in order to match the corresponding PCI_OHCI_INT_REG case in pci_ohci_write_reg().

2017-04-14MIPS: clockevent drivers: Set ->min_delta_ticks and ->max_delta_ticksNicolai Stange1-0/+2
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.

2017-02-14MIPS: Audit and remove any unnecessary uses of module.hPaul Gortmaker1-1/+1
Historically a lot of these existed because we did not have a distinction between what was modular code and what was providing support to modules via EXPORT_SYMBOL and friends. That changed when we forked out support for the latter into the export.h file. This means we should be able to reduce the usage of module.h in code that is obj-y Makefile or bool Kconfig. In the case of some code where it is modular, we can extend that to also include files that are building basic support functionality but not related to loading or registering the final module; such files also have no need whatsoever for module.h The advantage in removing such instances is that module.h itself sources about 15 other headers; adding significantly to what we feed cpp, and it can obscure what headers we are effectively using. Since module.h might have been the implicit source for init.h (for __init) and for export.h (for EXPORT_SYMBOL) we consider each instance for the presence of either and replace/add as needed. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. Build coverage of all the mips defconfigs revealed the module.h header was masking a couple of implicit include instances, so we add the appropriate headers there.

2015-09-03MIPS: loongson64/timer: Migrate to new 'set-state' interfaceViresh Kumar1-25/+21
Migrate loongson driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED.

2015-06-21MIPS: Loongson: Naming style cleanup and reworkHuacai Chen8-0/+1283
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.
