[PATCH v3 08/17] OMAP2,3: DSS2: Create platform_driver for each DSS HW IP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Senthilvadivu Guruswamy <svadivu@xxxxxx>

Hwmod adaptation design requires each of the DSS HW IP to be a platform driver. 
Platform driver of dsshw has to be registered before of dispc, rfbi, dsi1,
venc and omapdisplay driver should be after all the HW IPs. Sequence it with
arch_initcall and device_initcall_sync.
