Hi, this is the 4th series adding support for OV9281 which is quite similar to OV9282. This includes: * a small cleanup (Patch 1) * adding a new compatible (Patch 2 & 3) * adding support for regulators (Patch 4 & 5) * Fixing v4l2 subdev name depending on actual model name (Patch 6) * Add regmap support (Patch 7) Thanks for anyone doing review and giving a feedback. Here are the changes in v4: * Use platform data to set sensor name (Patch 6) * Fixed some style issues (Patch 7) Here are the changes in v3: * Removed struct field documentation as well (Patch 1) * Dropped v2 Patch 6 (wrong approach) * Added new Patch 6 to set subdev name according to model parsed form compatible * Added new Patch 7 adding regmap support This is a preparation to solve the defunct auto-increment using regmap's 'use_single_read' (still WIP) Here are the changes in v2: * Added Krzysztof's a-b for Patch 2 & 4 * Added Daniele's a-b for Patch 1 & 3 * Removed additional error message in ov9282_power_off * Renamed function from ov9282_configure_regulators to ov9282_get_regulators * Cleaned-up reading ID registers The regulator support is based on the driver from Raspberry Pi downstream kernel [1], the ID register read fix as well. Please refer to [2] why this fix is required. I can confirm this is necessary by checking with a Logic analyzer on the i2c bus.
