From 9f7e55d235b62e95043917fcb86a87064678074c Mon Sep 17 00:00:00 2001 From: Petr Cvek Date: Thu, 13 Dec 2018 10:39:13 -0500 Subject: media: i2c: ov9640: drop soc_camera code and switch to v4l2_async This patch removes the dependency on an obsoleted soc_camera from ov9640 driver and changes the code to be a standalone v4l2 async subdevice. It also adds GPIO allocations for power and reset signals (as they are not handled by soc_camera now). The values for waiting on GPIOs (reset and power) settling down were taken from the datasheet (> 1 ms after HW/SW reset). The upper limit was chosen as an arbitrary value. Also one occurrence of mdelay() was changed to msleep(). The delays were successfully tested on a real hardware. The patch makes ov9640 sensor again compatible with the pxa_camera driver.
