Hi folks -- particularly TIers working on mainline,

There are several regressions that started with v3.10-rc that no one's
fixed for over a month.  Some of them should be quite easy:

* 37xx EVM: boot fails
   - as of v3.10-rc1
   - Cause unknown

* 2420N800, 2430sdp: failed to get counter_32k resource
   - "omap2_sync32k_clocksource_init: failed to get counter_32k resource"
   - Cause unknown

* 2430SDP, 3730 Beagle XM, 3530 Beagle, 3517EVM, CM-T3517: {dmic,mcpdm} lookup failure
   - Cause unknown
   - These IP blocks don't exist on OMAP3xxx/AM35xx chips

* 3730 Beagle XM, am335xbone, CM-T3517: uart4_rx.uart4_rx mux failure
   - Cause unknown
I am able to reproduce this issue on 37xx EVM using non-dt boot (dt boot doesn't throw this error). But this is not started with v3.10-rc, it has been present on older kernels also( I verified on 3.9 kernel). This is because that for all instances of uart, serial driver expects a pad with default
mode which is not the case for uart4 in 37xx EVM.
Correct me if I am wrong.

Thanks and regards,
Lokesh

(For more details, see the logs at the link below.)

It would be good if people could step up to fix these before v3.10 comes
out.

Failing tests: fixed by posted patches
--------------------------------------

(none)


Failing tests: needing investigation
------------------------------------

Boot tests:

* 3517EVM & CM-T3517: boot hangs with NFS root
   - Likely some Kconfig, board file, and PM issues with EMAC
   - Longstanding bug
   - Not currently part of the automated test suite

* 37xx EVM: boot fails
   - as of v3.10-rc1
   - Cause unknown

Boot warnings:

* 2420N800, 2430sdp: failed to get counter_32k resource
   - "omap2_sync32k_clocksource_init: failed to get counter_32k resource"
   - Cause unknown

* CM-T3517: L3 in-band error with IPSS during boot
   - Cause unknown but see http://marc.info/?l=linux-omap&m=134833869730129&w=2
   - Longstanding issue; does not occur on the 3517EVM

* 2430SDP, 3730 Beagle XM, 3530 Beagle, 3517EVM, CM-T3517: {dmic,mcpdm} lookup failure
   - Cause unknown
   - These IP blocks don't exist on OMAP3xxx/AM35xx chips

* 3730 Beagle XM, am335xbone, CM-T3517: uart4_rx.uart4_rx mux failure
   - Cause unknown

PM tests:

* 2430sdp: power domains not entering retention
   - Cause unknown

* 3730 Beagle XM: does not serial wake from off-idle suspend when console
   UART doesn't clock-gate ("debug ignore_loglevel")
   - Cause unknown
   - Not yet part of the automated test suite
   - Re-tested at v3.7; still failing:
     http://www.pwsan.com/omap/transcripts/20121211-3730beaglexm-3.7-pm-offmode-fail-debug.txt

* 4430es2panda: pwrdm state mismatch on CAM, DSS

* 4430es2panda: CORE, TESLA, IVAHD, L3INIT didn't enter target state
   - Probably due to lack of reset code for M3, DSP, SL2IF, FSUSB
     per discussion with Tero Kristo
   - Likely dependent on the bootloader version
     - fails with 2012.07-00136-g755de79
   - http://marc.info/?l=linux-arm-kernel&m=136432340618226&w=2

* 4430es2panda: MPU, ABE didn't enter target state
   - New for v3.10-rc

* 4460pandaes: pwrdm state mismatch on DSS, ABE, IVAHD, TESLA

* 4460pandaes: chip not entering retention in dynamic idle
   - Presumably 4430es2panda also fails this
   - Suspend-to-RAM enters full chip retention

Other:

* 4430es2panda: omap_hwmod: l3_instr: _wait_target_disable failed
   - Unknown cause; could be due to the lack of hierarchical enable/disable
     in hwmod code
   - Jon Hunter and Santosh Shilimkar report this does not appear with
     the same X-loader/bootloader on his 4430ES2.3 Panda, so could be
     ES-level dependent


Failing tests: reported by others
---------------------------------

- RTC wakeup from suspend broken on 3730beaglexm
   - as of v3.10-rc1
