Subject: [PATCH v2 0/9] Tegra114: implement EMC support
Date: Wed, 20 Aug 2025 18:13:14 +0300 [thread overview]
Message-ID: <20250820151323.167772-1-clamor95@gmail.com> (raw)
Add support for External Memory Controller found in Tegra 4 SoC along
with adjustments required for it to work properly.
Tested on ASUS TF701T (T40X) and Nvidia Tegratab (T40S). Both work fine.
This patchset requires DFLL patches to be applied first to avoid
issues https://patchwork.ozlabs.org/project/linux-tegra/list/?series=464976

Changes in v2:
- fix programming completion detection (changed EMC reg to MC reg reading)
- Tegra114 incorporated into Tegra124 dt-bindings schema
