Merge tag 'omap-for-v4.1/fixes-0' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/fixes-non-critical
Merge "omap non-urgent fixes for v4.1" from Tony Lindgren:
Fixes for omaps that were not considered urgent enough for the -rc cycle.
This is mostly to enable errata 798181 and thermal support for dra7,
configure ocp2scp for am437x, remove dead code for OMAP4_ERRATA_I688
and fix build warnings for omap1510 only config.
* tag 'omap-for-v4.1/fixes-0' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: DRA7: Enable Cortex A15 errata 798181
ARM: dts: am57xx-beagle-x15: Add thermal map to include fan and tmp102
ARM: dts: DRA7: Add bandgap and related thermal nodes
bus: ocp2scp: SYNC2 value should be changed to 0x6
ARM: dts: am4372: Add "ti,am437x-ocp2scp" as compatible string for OCP2SCP
ARM: OMAP2+: remove superfluous NULL pointer check
ARM: OMAP4: remove dead kconfig option OMAP4_ERRATA_I688
MAINTAINERS: add OMAP defconfigs under OMAP SUPPORT
ARM: OMAP1: PM: fix some build warnings on 1510-only Kconfigs

- If a data is stalled inside asynchronous bridge because of back

- until next reset of the system (No recovery procedure once the
- issue is hit, the path remains consistently broken). Async bridge
- can be found on path between MPU to EMIF and MPU to L3 interconnect.
- This situation can happen only when the idle is initiated by a
- Master Request Disconnection (which is trigged by software when
- executing WFI on CPU).
- The work-around for this errata needs all the initiators connected
- through async bridge must ensure that data path is properly drained
- before issuing WFI. This condition will be met if one Strongly ordered
- access is performed to the target right before executing the WFI.
- In MPU case, L3 T2ASYNC FIFO and DDR T2ASYNC FIFO needs to be drained.
- IO barrier ensure that there is no synchronisation loss on initiators
- operating on both interconnect port simultaneously.
