Subject: [PATCH v3 00/22] tegra-video: add CSI support for Tegra20 and Tegra30
Add support for MIPI CSI device found in Tegra20 and Tegra30 SoC along
with a set of changes required for that.
---
Changes in v2:
- vi_sensor gated through csus
- TEGRA30_CLK_CLK_MAX moved to clk-tegra30
- adjusted commit titles and messages
- clk_register_clkdev dropped from pad clock registration
- removed tegra30-vi/vip and used tegra20 fallback
- added separate csi schema for tegra20-csi and tegra30-csi
- fixet number of VI channels
- adjusted tegra_vi_out naming
- fixed yuv_input_format to main_input_format
- MIPI calibration refsctored for Tegra114+ and added support for
pre-Tegra114 to use CSI as a MIPI calibration device
- switched ENOMEM to EBUSY
- added check into tegra_channel_get_remote_csi_subdev
- moved avdd-dsi-csi-supply into CSI
- next_fs_sp_idx > next_fs_sp_value
- removed host1x_syncpt_incr from framecounted syncpoint
- csi subdev request moved before frame cycle
Changes in v3:
- tegra20 and tegra30 csi schema merged
- removed unneeded properties and requirements from schema
- improved vendor specific properties description
- added tegra20 csus parent mux
- improved commit descriptions
- redesigned MIPI-calibration to expose less SoC related data into header
- commit "staging: media: tegra-video: csi: add support for SoCs with integrated
MIPI calibration" dropped as unneeded
- improved tegra_channel_get_remote_device_subdev logic
- avdd-dsi-csi-supply moved from vi to csi for p2597 and p3450-0000
- software syncpoint counters switched to direct reading
- adjusted planar formats offset calculation
