2022-06-21mips: lantiq: falcon: Fix refcount leak bug in sysctrlLiang He
In ltq_soc_init(), of_find_compatible_node() will return a node pointer with refcount incremented. We should use of_node_put() when it is not used anymore. Signed-off-by: Liang He <windhl@126.com> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2022-03-30MIPS: lantiq: check the return value of kzalloc()Xiaoke Wang
kzalloc() is a memory allocation function which can return NULL when some internal memory errors happen. So it is better to check the return value of it to prevent potential wrong memory access or memory leak.

2017-09-04MIPS: lantiq: Replace ltq_boot_select() with dummy implementation.Ralf Baechle
This will only be used until the last usage of ltq_boot_select() has been removed. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2017-09-04MIPS: lantiq: remove ltq_reset_cause() and ltq_boot_select()Hauke Mehrtens
Do not export the ltq_reset_cause() and ltq_boot_select() function any more. ltq_reset_cause() was accessed by the watchdog driver before to see why the last reset happened, this is now done through direct access of the register over regmap. The bits in this register are anyway different between the xrx200 and the falcon SoC. ltq_boot_select() is not used any more and was used by the flash drivers to check if the system was booted from this flash type, now the drivers should depend on the device tree only.
