But CAL DPHY require LVDSRX_96M_GFCLK to be active. When this domain is set to HWSUP the LVDSRX_96M_GFCLK is on;y active when VIP1 clock is also active. If only CAL on DRA72x (which uses the VIP2 clkctrl) probes the CAM domain is enabled but the LVDSRX_96M_GFCLK is left gated. Since LVDSRX_96M_GFCLK is sourcing the input clock to the DPHY then actual frame capture cannot start as the phy are inactive. So we either have to also enabled VIP1 even if we don't intend on using it or we need to set the CAM domain to use SWSUP only. This patch implements the latter.
