[PATCH 0/5] MIPS: Alchemy updates for 4.20+

[PATCH 0/5] MIPS: Alchemy updates for 4.20+

[Manuel Lauss]

Here's a bunch of fixes to restore almost all functionality to the
Alchemy devboards, against 4.20-rc7+.

#1 gets rid of a warning in the clockevent code,
#2 let's the Alchemy on-chip ethernet driver build again,
#3 removes board-specific IrDA code, as the driver is gone,
#4 sync up overrides with latest cpu-features
#5 adds dma_masks to sound and mmc devices to get them
   working again.

Verified on the DB1300 and DB1500 boards.

Manuel Lauss (5):
  MIPS: alchemy: cpu_all_mask is forbidden for clock event devices
  net: drivers/amd: restore access to MIPS Alchemy platform
  MIPS: Alchemy: drop DB1000 IrDA support bits
  MIPS: Alchemy: update cpu-feature-overrides
  MIPS: Alchemy: update dma masks for devboard devices

[PATCH 1/5] MIPS: alchemy: cpu_all_mask is forbidden for clock event devices

[Manuel Lauss]

change alchemy clock event device cpu_all_mask to cpu_possible_mask.
Gets rid of a warning, which then does the same substitution:
WARNING: CPU: 0 PID: 0 at kernel/time/clockevents.c:468 clockevents_register_device+0x130/0x140
rtcmatch2 cpumask == cpu_all_mask, using cpu_possible_mask instead

[PATCH 2/5] net: drivers/amd: restore access to MIPS Alchemy platform

[Manuel Lauss]

The MIPS Alchemy platform needs access to the au1000_eth.c
driver, which resides in the AMD driver directory (as the
chips were at a time made by AMD).
