2019-06-12drm/stm: dsi: add power on/off phy opsYannick Fertré
These new physical operations are helpful to power_on/off the dsi wrapper. If the dsi wrapper is powered in video mode, the display controller (ltdc) register access will hang when DSI fifos are full.

Bridge drivers/helpers shouldn't be clobbering the drvdata, since a parent driver might need to own this. Instead, let's return our 'dw_mipi_dsi' object and have callers pass that back to us for removal.

2017-09-08drm/stm: fix warning about multiplication in conditionArnd Bergmann
gcc-7 complains about multiplying within a condition being suspicious: drivers/gpu/drm/stm/dw_mipi_dsi-stm.c: In function 'dsi_pll_get_clkout_khz': drivers/gpu/drm/stm/dw_mipi_dsi-stm.c:117:10: error: '*' in boolean context, suggest '&&' instead [-Werror=int-in-bool-context] The code here is correct, but can be easily rephrased to make that more obvious. I also swap out the error handling and the normal code path for clarity.
