| Subject: dmaengine: pl330: report BURST residue granularity |
| |
| From: Marek Szyprowski <m.szyprowski@samsung.com> |
| |
| [ Upstream commit e3f329c600033f011a978a8bc4ddb1e2e94c4f4d ] |
| |
| 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") |
