Subject: [PATCH] powerpc: 85xx: add support for the TP-Link TL-WDR4900 v1
|
||||
board
|
||||
|
||||
This patch adds support for the TP-Link TL-WDR4900 v1
|
||||
concurrent dual-band wireless router. The devices uses

Subject: spi-fsl-espi: avoid frequent high order allocations
|
||||
|
||||
The driver allocates 64KiB of memory fro a local buffer before
|
||||
each transfer and releases that afterwards. When the memory is
|
||||
fragmented this allocation often fails and causes a warning like
|
||||
this:
|
||||
|
||||
kworker/u2:2: page allocation failure: order:4, mode:0x10c0d0
|
||||
