ram: Introduce K3 AM654 DDR Sub System driver K3 based AM654 devices has DDR memory subsystem that comprises Synopys DDR controller, Synopsis DDR phy and wrapper logic to intergrate these blocks into the device. This DDR subsystem provides an interface to external SDRAM devices. Adding support for the initialization of the external SDRAM devices by configuring the DDRSS registers and using the buitin PHY routines.

arm: k3: Add a wrapper to get tisci handle Create a wrapper to get the ti sci handle. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> 2019-03-08 06:17:33 +00:00			`struct ti_sci_handle *get_ti_sci_handle(void);`
arm: k3: Add support for updating msmc dt node Certain parts of msmc sram can be used by DMSC or can be marked as L3 cache. Since the available size can vary, changing DT every time the size varies might be painful. So, query this information using TISCI cmd and fixup the DT for kernel. Fixing up DT does the following: - Create a sram node if not available - update the reg property with available size - update ranges property - loop through available sub nodes and delete it if: - mentioned size is out if available range - subnode represents l3 cache or dmsc usage.
