2021-04-27drm/msm/dsi: fix msm_dsi_phy_get_clk_provider return codeDmitry Baryshkov
msm_dsi_phy_get_clk_provider() always returns two provided clocks, so return 0 instead of returning incorrect -EINVAL error code.

2021-04-07drm/msm/dsi: stop passing src_pll_id to the phy_enable callDmitry Baryshkov
Phy driver already knows the source PLL id basing on the set usecase and the current PLL id. Stop passing it to the phy_enable call. As a reminder, dsi manager will always use DSI 0 as a clock master in a slave mode, so PLL 0 is always a clocksource for DSI 0 and it is always a clocksource for DSI 1 too unless DSI 1 is used in the standalone mode.
