| |
Starting from commit e45f243409db ("firmware: meson_sm: populate platform devices from sm device tree data") pwrc is probed successfully and disables unused pwr domains. By A1 SoC family design, any TEE requires DMA pwr domain always enabled.
Signed-off-by: Alexey Romanov <avromanov@sberdevices.ru> --- I'm not entirely sure if this domain should always be enabled on or it should be separately enabled in dts file. Comments are welcome. --- drivers/soc/amlogic/meson-secure-pwrc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
