| Subject: ARM: dts: ls1021a: fix QuadSPI-memory reg range |
| |
| From: Matthias Schiffer <matthias.schiffer@ew.tq-group.com> |
| |
| [ Upstream commit 81dbbb417da4d1ac407dca5b434d39d5b6b91ef3 ] |
| |
| According to the Reference Manual, the correct size is 512 MiB. |
| |
| Without this fix, probing the QSPI fails: |
| |
| fsl-quadspi 1550000.spi: ioremap failed for resource |
| [mem 0x40000000-0x7fffffff] |
| fsl-quadspi 1550000.spi: Freescale QuadSPI probe failed |
| fsl-quadspi: probe of 1550000.spi failed with error -12 |
| |
| Fixes: 85f8ee78ab72 ("ARM: dts: ls1021a: Add support for QSPI with ls1021a SoC") |
