2022-07-25arm: mach-k3: Rename SOC_K3_AM6 to SOC_K3_AM654Andrew Davis1-1/+1
The first AM6x device was the AM654x, but being the first we named it just AM6, since more devices have come out with this same prefix we should switch it to the normal convention of using the full name of the first compatibility device the series. This makes what device we are talking about more clear and matches all the K3 devices added since. Signed-off-by: Andrew Davis <afd@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>

Enable DRAM ASR, auto self-refresh, conditionally, based on DT PWRCTL register bits. While ASR does save considerable amount of power at runtime automatically, it also causes LTDC underruns on large panels.

The support of a predefined DDR PHY tuning result is removed for STM32MP1 driver because it is not needed at the supported frequency when built-in calibration is executed. The calibration parameters were provided in the device tree by the optional node "st,phy-cal", activated in ddr helper file by the compilation flag DDR_PHY_CAL_SKIP and filled with values generated by the CubeMX DDR utilities. This patch - updates the binding file to remove "st,phy-cal" support - updates the device trees and remove the associated defines - simplifies the STM32MP1 DDR driver and remove the support of the optional parameter "st,phy-cal" After this patch, the built-in calibration is always executed and the calibration registers are moved in the phy dynamic part; that allows manual tests.
