* MIPS: ralink: export rt_sysc_membase for rt2880_wdt.cRandy Dunlap2021-06-03
| | | | | | | | | | | | | | | | | | | | | | [ Upstream commit fef532ea0cd871afab7d9a7b6e9da99ac2c24371 ] rt2880_wdt.c uses (well, attempts to use) rt_sysc_membase. However, when this watchdog driver is built as a loadable module, there is a build error since the rt_sysc_membase symbol is not exported. Export it to quell the build error. ERROR: modpost: "rt_sysc_membase" [drivers/watchdog/rt2880_wdt.ko] undefined!

* MIPS: ralink: Fix mt7620 nd_sd pinmuxMathias Kresin2018-12-13
| | | | | | | | | | | | | | | | | | | | | | commit 7d35baa4e9ec4b717bc0e58a39cdb6a1c50f5465 upstream. In case the nd_sd group is set to the sd-card function, Pins 45 + 46 are configured as GPIOs. If they are blocked by the sd function, they can't be used as GPIOs.

* MIPS: ralink: Remove ralink_halt()NeilBrown2018-03-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 891731f6a5dbe508d12443175a7e166a2fba616a upstream. ralink_halt() does nothing that machine_halt() doesn't already do, so it adds no value. It actually causes incorrect behaviour due to the "unreachable()" at the end. This tells the compiler that the end of the function will never be reached, which isn't true. The compiler responds by not adding a 'return' instruction, so control simply moves on to whatever bytes come afterwards in memory. In my tested, that was the ralink_restart() function. This means that an attempt to 'halt' the machine would actually cause a reboot. So remove ralink_halt() so that a 'halt' really does halt.

* MIPS: ralink: Fix clearing the illegal access interruptJonas Gorski2015-06-01
| | | | | | | | | | | | | | | | | | Due to a typo the illegal access interrupt is never cleared in by the interupt handler, causing an effective deadlock on the first illegal access. This was broken since the code was introduced in 5433acd81e87 ("MIPS: ralink: add illegal access driver"), but only exposed when the Kconfig symbol was added, thus enabling the code.
