This is a follow-up for the series[1] adding new bus and memory drivers to better support the TI LCD controller on the da850-lcdk board. The general consensus of the discussion that followed was that DT is not the right tool for this kind of SoC performance tweaks. In order to avoid committing to stable DT bindings, we only introduce two common properties (compatible and reg) while the configuration register values are hard-coded for each board (currently only lcdk). In the future, once linux gets a proper framework for performance knobs, we'll convert this driver to using the better solution. I'm sending a single patch this time as RFC to get some reviews and see it the approach is viewed as correct. [1] https://lkml.org/lkml/2016/10/17/613 v1 -> v2: - changed the compatible string to make it more descriptive - changed the DT bindings description to describe the device, not the driver's functionalities - switched to using of_machine_is_compatible() instead of handcoding the same functionality - used platform_get_resource() instead of ioremapping registers by hand Bartosz Golaszewski (1): ARM: memory: da8xx-ddrctl: new driver .../memory-controllers/ti-da8xx-ddrctl.txt | 20 +++ drivers/memory/Kconfig | 8 + drivers/memory/Makefile | 1 + drivers/memory/da8xx-ddrctl.c | 175 +++++++++++++++++++++ 4 files changed, 204 insertions(+) create mode 100644 Documentation/devicetree/bindings/memory-controllers/ti-da8xx-ddrctl.txt create mode 100644 drivers/memory/da8xx-ddrctl.c -- 2.9.3 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
