2020-01-17media: ov6650: Fix .get_fmt() V4L2_SUBDEV_FORMAT_TRY supportJanusz Krzysztofik1-3/+9
commit 39034bb0c26b76a2c3abc54aa28c185f18b40c2f upstream. Commit da298c6d98d5 ("[media] v4l2: replace video op g_mbus_fmt by pad op get_fmt") converted a former ov6650_g_fmt() video operation callback to an ov6650_get_fmt() pad operation callback. However, the converted function disregards a format->which flag that pad operations should obey and always returns active frame format settings. That can be fixed by always responding to V4L2_SUBDEV_FORMAT_TRY with -EINVAL, or providing the response from a pad config argument, likely updated by a former user call to V4L2_SUBDEV_FORMAT_TRY .set_fmt(). Since implementation of the latter is trivial, go for it.

2020-01-17media: ov6650: Fix some format attributes not under controlJanusz Krzysztofik1-12/+39
commit 1c6a2b63095154bbf9e8f38d79487a728331bf65 upstream. User arguments passed to .get/set_fmt() pad operation callbacks may contain unsupported values. The driver takes control over frame size and pixel code as well as colorspace and field attributes but has never cared for remainig format attributes, i.e., ycbcr_enc, quantization and xfer_func, introduced by commit 11ff030c7365 ("[media] v4l2-mediabus: improve colorspace support"). Fix it. Set up a static v4l2_mbus_framefmt structure with attributes initialized to reasonable defaults and use it for updating content of user provided arguments. In case of V4L2_SUBDEV_FORMAT_ACTIVE, postpone frame size update, now performed from inside ov6650_s_fmt() helper, util the user argument is first updated in ov6650_set_fmt() with default frame format content. For V4L2_SUBDEV_FORMAT_TRY, don't copy all attributes to pad config, only those handled by the driver, then fill the response with the default frame format updated with resulting pad config format code and frame size.

Since the driver initial submission, crop rectangle width and height settings are not updated correctly when rectangle offset settings are applied on hardware.

Later on, commit 10d5509c8d50 ("[media] v4l2: remove g/s_crop from video ops") replaced s_crop() video operation using that const argument with set_selection() pad operation which had a corresponding argument not constified, however the original behavior of the driver was not restored. Since that time, any hardware alignment applied on a user requested crop rectangle is not passed back to the user calling .set_selection() as it should be.

This means that a media device driver that it's waiting for this subdevice to be bound, will prematurely expose its media device node to userspace because if something goes wrong the media entity will be cleaned up again on the ov2680 probe function.

[ Upstream commit 9cfd2753f8f3923f89cbb15f940f3aa0e7202d3e ] Several CEC functions are actually specific for use with receivers, i.e. they should be part of the V4L2 subsystem, not CEC. These functions deal with validating and modifying EDIDs for (HDMI) receivers, and they do not actually have anything to do with the CEC subsystem and whether or not CEC is enabled.

[ Upstream commit bccb89cf9cd07a0690d519696a00c00a973b3fe4 ] This driver returns an error if unsupported media bus pixel code is requested by VIDIOC_SUBDEV_S_FMT. But according to Documentation/media/uapi/v4l/vidioc-subdev-g-fmt.rst, Drivers must not return an error solely because the requested format doesn't match the device capabilities. They must instead modify the format to match what the hardware can provide. So select default format code and return success in that case. This is detected by v4l2-compliance.

commit 933c1320847f5ed6b61a7d10f0a948aa98ccd7b0 upstream. After removal of clock_start() from before soc_camera_init_i2c() in soc_camera_probe() by commit 9aea470b399d ("[media] soc-camera: switch I2C subdevice drivers to use v4l2-clk") introduced in v3.11, the ov6650 driver could no longer probe the sensor successfully because its clock was no longer turned on in advance. The issue was initially worked around by adding that missing clock_start() equivalent to OMAP1 camera interface driver - the only user of this sensor - but a propoer fix should be rather implemented in the sensor driver code itself. Fix the issue by inserting a delay between the clock is turned on and the sensor I2C registers are read for the first time. Tested on Amstrad Delta with now out of tree but still locally maintained omap1_camera host driver.

commit 61da76beef1e4f0b6ba7be4f8d0cf0dac7ce1f55 upstream. The following commits: commit f6dd927f34d6 ("[media] media: ov7670: calculate framerate properly for ov7675") commit 04ee6d92047e ("[media] media: ov7670: add possibility to bypass pll for ov7675") introduced the ability to bypass PLL multiplier and use input clock (xvclk) as pixel clock output frequency for ov7675 sensor. PLL is bypassed using register DBLV[7:6], according to ov7670 and ov7675 sensor manuals. Macros used to set DBLV register seem wrong in the driver, as their values do not match what reported in the datasheet. Fix by changing DBLV_* macros to use bits [7:6] and set bits [3:0] to default 0x0a reserved value (according to datasheets). While at there, remove a write to DBLV register in "ov7675_set_framerate()" that over-writes the previous one to the same register that takes "info->pll_bypass" flag into account instead of setting PLL multiplier to 4x unconditionally. And, while at there, since "info->pll_bypass" is only used in set/get_framerate() functions used by ov7675 only, it is not necessary to check for the device id at probe time to make sure that when using ov7670 "info->pll_bypass" is set to false.

[ Upstream commit 12aceee1f412c3ddc7750155fec06c906f14ab51 ] The runtime PM of this device is enabled after v4l2_ctrl_handler_setup(), and this makes this device's runtime PM usage count a negative value. The ov7740_set_ctrl() tries to do something only if the device's runtime PM usage counter is nonzero. ov7740_set_ctrl() { if (!pm_runtime_get_if_in_use(&client->dev)) return 0; <do something>; pm_runtime_put(&client->dev); return ret; } However, the ov7740_set_ctrl() is called by v4l2_ctrl_handler_setup() while the runtime PM of this device is not yet enabled. In this case, the pm_runtime_get_if_in_use() returns -EINVAL (!= 0). Therefore we can't bail out of this function and the usage count is decreased by pm_runtime_put() without increment. This fixes this problem by enabling the runtime PM of this device before v4l2_ctrl_handler_setup() so that the ov7740_set_ctrl() is always called when the runtime PM is enabled.

commit aa4bb8b8838ffcc776a79f49a4d7476b82405349 upstream. Rework the MIPI interface startup sequence with the following changes: - Remove MIPI bus initialization from the initial settings blob - At set_power(1) time power up MIPI Tx/Rx and set data and clock lanes in LP11 during 'sleep' and 'idle' with MIPI clock in non-continuous mode. - At s_stream time enable/disable the MIPI interface output. - Restore default settings at set_power(0) time. Before this commit the sensor MIPI interface was initialized with settings that require a start/stop sequence at power-up time in order to force lanes into LP11 state, as they were initialized in LP00 when in 'sleep mode', which is assumed to be the sensor manual definition for the D-PHY defined stop mode. The stream start/stop was performed by enabling disabling clock gating, and had the side effect to change the lanes sleep mode configuration when stream was stopped. Clock gating/ungating: - ret = ov5640_mod_reg(sensor, OV5640_REG_MIPI_CTRL00, BIT(5), - on ? 0 : BIT(5)); - if (ret) Set lanes in LP11 when in 'sleep mode': - ret = ov5640_write_reg(sensor, OV5640_REG_PAD_OUTPUT00, - on ? 0x00 : 0x70); This commit fixes an issue reported by Jagan Teki on i.MX6 platforms that prevents the host interface from powering up correctly: https://lkml.org/lkml/2018/6/1/38 It also improves MIPI capture operations stability on my testing platform where MIPI capture often failed and returned all-purple frames.
