Subject[Patch v5 0/4] memory: tegra: Add MC channels and error logging
Date
From tegra186 onward, memory controllers support multiple channels.
Add memory controller channels in device tree and add support to map
address spaces of these channels in tegra MC driver.
When memory controller interrupt occurs, registers from these channels
are required to be read in order to get error information.
Add error logging support from tegra186 onward for memory controller
interrupts.

Ashish Mhetre (4):
memory: tegra: Add memory controller channels support
memory: tegra: Add MC error logging on tegra186 onward
dt-bindings: memory: Update reg maxitems for tegra186
arm64: tegra: Add memory controller channels

- Added newlines after every break statement of all switch cases
- Fixed compile error with W=1 build
- Fixed the interrupt mask bit logic

Changes in v3:
- Removed unnecessary ifdefs
