2020-03-04powerpc/83xx: Add some error handling in 'quirk_mpc8360e_qe_enet10()'Christophe JAILLET1-1/+4
In some error handling path, we should call "of_node_put(np_par)" or some resource may be leaking in case of error. Fixes: 8159df72d43e ("83xx: add support for the kmeter1 board.")

2019-12-09soc: fsl: qe: move calls of qe_ic_init out of arch/powerpc/Rasmus Villemoes1-1/+0
Having to call qe_ic_init() from platform-specific code makes it awkward to allow building the QE drivers for ARM. It's also a needless duplication of code, and slightly error-prone: Instead of the caller needing to know the details of whether the QUICC Engine High and QUICC Engine Low are actually the same interrupt (see e.g. the machine_is() in mpc85xx_mds_qeic_init), just let the init function choose the appropriate handlers after it has parsed the DT and figured it out. If the two interrupts are distinct, use separate handlers, otherwise use the handler which first checks the CHIVEC register (for the high priority interrupts), then the CIVEC. All existing callers pass 0 for flags, so continue to do that from the new single caller. Later cleanups will remove that argument from qe_ic_init and simplify the body, as well as make qe_ic_init into a proper init function for an IRQCHIP_DECLARE, eliminating the need to manually look up the fsl,qe-ic node.

2016-09-25powerpc/83xx: factor out the common codes of setup arch functionsKevin Hao1-4/+1
Factor out the common codes of setup arch functions to a separate function. It does make no sense to print a board specific info in setup arch functions, so use a more general one. For ASP8347E board, there is no pci device node. So it is safe to invoke mpc83xx_setup_pci() in its setup arch function even there is no such invocation in its original setup arch function.

2016-07-21powerpc: Move 32-bit probe() machine to later in the boot processBenjamin Herrenschmidt1-2/+1
This converts all the 32-bit platforms to use the expanded device-tree which is a pretty mechanical change. Unlike 64-bit, the 32-bit kernel didn't rely on platform initializations to setup the MMU since it sets it up entirely before probe_machine() so the move has comparatively less consequences though it's a bigger patch.
