Subject: [PATCH v2 0/4] memory: tegra: Add MC error logging support for Tegra264 SoC

In Tegra264, different components from memory subsystems like Memory
Controller Fabric (MCF), HUB, HUB Common (HUBC), Side Band Shim (SBS)
and MC Channels have different interrupt lines for receiving memory
controller error interrupts. This patch set includes changes to add
support and enable Memory Controller error logging for Tegra264.

Ketan Patil (4):
  memory: tegra: Group mc-err related registers
  memory: tegra: Group register and fields
  memory: tegra: Add support for multiple irqs
  memory: tegra: Add MC error logging support for Tegra264

Changes in v2:
- Fixed warning due to use of uninitialized variable by returning back
from the function
- Removed unnecessary extern declaration of tegra264_mc_ops
- Updated tegra20_mc_irq_handlers, tegra264_mc_irq_handlers and
tegra264_mc_ops to static
