Hardware issue: - Reading register RCPM_IPPDEXPCR1 always return zero, this causes system firmware could not get correct information and wrongly do clock gating for all wakeup source IP during system suspend. Then those IPs will never get chance to wake system. Workaround: - Copy register RCPM_IPPDEXPCR1's setting to register SCFG_SPARECR8 to allow system firmware's psci method read it and do things accordingly.

ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mripard/linux into arm/drivers Allwinner MBUS and DMA-ops rework The Allwinner SoCs have a number of high-bandwidth devices connected to a memory bus with a different RAM mapping than the CPU. This was addressed before through drivers setting the DMA offsets directly, and subsequently changed to calls to dma_direct_set_offset. However that wasn't really meant to be exported to modules (and thus drivers). The duplicated code also led to small inconsistencies across drivers in how we dealt with DT backward compatibility. Move all that DMA setup code into a platform bus notifier to share that code and remove the export on dma_direct_set_offset. * tag 'sunxi-rework-mbus' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mripard/linux: dma-mapping: remove the dma_direct_set_offset export media: sun8i-di: Remove the call to of_dma_configure media: cedrus: Remove the MBUS quirks media: sun6i: Remove the MBUS quirks media: sun4i: Remove the MBUS quirks drm/sun4i: backend: Remove the MBUS quirks soc: sunxi: Deal with the MBUS DMA offsets in a central place drm/sun4i: backend: Fix probe failure with multiple backends Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2020-11-21soc: ti: Fix reference imbalance in knav_dma_probeZhang Qilong1-2/+11
The patch fix two reference leak. 1) pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to call put operation will result in reference leak. 2) The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced. We fix it by: 1) adding call pm_runtime_put_noidle or pm_runtime_put_sync in error handling. 2) adding pm_runtime_disable in error handling, to keep usage counter and disable depth balanced.
