Merge tag 'soc-fsl-next-v4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/leo/linux into next/drivers
NXP/FSL SoC drivers updates for v4.20 take 2
- Update qbman driver to better work with CPU hotplug
- Add Kconfig dependency of 64-bit DMA addressing for qbman driver
- Use last reponse to determine valid bit for qbman driver
- Defer bman_portals probe if bman is not probed
- Add interrupt coalescing APIs to qbman driver
* tag 'soc-fsl-next-v4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/leo/linux:
soc: fsl: qbman: add interrupt coalesce changing APIs
soc: fsl: bman_portals: defer probe after bman's probe
soc: fsl: qbman: Use last response to determine valid bit
soc: fsl: qbman: Add 64 bit DMA addressing requirement to QBMan
soc: fsl: qbman: replace CPU 0 with any online CPU in hotplug handlers
soc: fsl: qbman: Check if CPU is offline when initializing portals
soc: fsl: qman_portals: defer probe after qman's probe
soc: fsl: qbman: add APIs to retrieve the probing status
soc: fsl: qe: Fix copy/paste bug in ucc_get_tdm_sync_shift()
soc: fsl: qbman: qman: avoid allocating from non existing gen_pool
