What keeps MIPI clock enabled after completion of the
tegra_mipi_calibrate() invocation?
MIPI clock is disabled at end of tegra_mipi_calibrate and is re-enabled
during tegra_mipi_wait.
I think I should fix this to keep the clock enabled till calibration
results are latched.
All consumers of tegra_mipi_calibrate() will call tegra_mipi_wait().
So will remove clk_disable mipi clk at end of tegra_mipi_calibrate() and
clk_enable mipi_clk at beginning of tegra_mipi_wait()
Isn't it possible to perform the calibration after enabling CSI and
before of starting the sensor streaming?
Currently this is what I am doing. Triggering calibration start during
CSI receiver being ready and then sensor streaming will happen where
internal MIPI CAL detects for LP -> HS transition and applies results to
pads. So checking for calibration results after sensor stream is enabled
