Subject: [PATCH] ahci_qoriq: bug fix for ecc_addr
|
|
|
|
Original driver expect a register node with name "sata-ecc"
|
|
this node is of 64 bit wide.
|
|
In ACPI such nodes can be provided with QWordMemory, but
|
|
QWordMemory can not hold DescriptorName more than 4 characters.
|
|
|
|
Therefore this patch changes platform property retrival based
|
|
upon index instead of named.
