soc: ti: QMSS: Fix usage of irq_set_affinity_hint

2018-11-21T08:24:09+00:00

commit 832ad0e3da4510fd17f98804abe512ea9a747035 upstream. The Keystone QMSS driver is pretty damaged, in the sense that it does things like this: irq_set_affinity_hint(irq, to_cpumask(&cpu_map)); where cpu_map is a local variable. As we leave the function, this will point to nowhere-land, and things will end-up badly. Instead, let's use a proper cpumask that gets allocated, giving the driver a chance to actually work with things like irqbalance as well as have a hypothetical 64bit future.

soc/tegra: pmc: Fix child-node lookup

2018-11-13T19:15:12+00:00

commit 1dc6bd5e39a29453bdcc17348dd2a89f1aa4004e upstream. Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children. To make things worse, the parent pmc node could end up being prematurely freed as of_find_node_by_name() drops a reference to its first argument.

soc: imx: gpcv2: Do not pass static memory as platform data

2018-08-03T05:50:40+00:00

[ Upstream commit 050f810e238f268670f14a8f8b793ba2dbf2e92f ] Platform device core assumes the ownership of dev.platform_data as well as that it is dynamically allocated and it will try to kfree it as a part of platform_device_release(). Change the code to use platform_device_add_data() n instead of a pointer to a static memory to avoid causing a BUG() when calling platform_device_put(). The problem can be reproduced by artificially enabling the error path of platform_device_add() call (around line 357). Note that this change also allows us to constify imx7_pgc_domains, since we no longer need to be able to modify it.

MIPS: lantiq: gphy: Drop reboot/remove reset asserts

commit 32795631e67e16141aa5e065c28ba03bf17abb90 upstream. While doing a global software reset, these bits are not cleared and let some bootloader fail to initialise the GPHYs. The bootloader don't expect the GPHYs in reset, as they aren't during power on. The asserts were a workaround for a wrong syscon-reboot mask. With a mask set which includes the GPHY resets, these resets aren't required any more.
