Subject: [PATCH] dmaengine: pl330: report BURST residue granularity
Git-commit: e3f329c600033f011a978a8bc4ddb1e2e94c4f4d
Patch-mainline: v4.18-rc4
References: bsc#1051510
The reported residue is already calculated in BURST unit granularity, so
advertise this capability properly to other devices in the system.
Fixes: aee4d1fac887 ("dmaengine: pl330: improve pl330_tx_status() function")
