Calling acpi_bus_get_device() may end allocating resources that aren't freed. So, add a notice about that, as, if those drivers get out of staging, we may need some changes.

2020-05-20media: atomisp: disable the dynamic and reserved poolsMauro Carvalho Chehab1-0/+6
The memory management code for atomisp is complex: it has 2 extra pools (plus some ION-specific code). The code for those extra pools are complex, and there are even some parts of code over there that were forked from some mm/ code, probably from Kernel 3.10. Let's just use a single one, in order to make the driver simpler. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

There is an ov2680 driver mainstream. Use the read/write routines from it, as the ones inside this driver are generating some errors: ov2680 i2c-OVTI2680:00: ov2680_i2c_write: i2c write reg=0x3086, value 0x00, error -121 Maybe the code that changes from/to BE are not right.

2020-05-20media: atomisp: change the code to properly wait for sensorMauro Carvalho Chehab3-11/+20
The sensor should finish its init before atomisp driver, as otherwise the atomisp driver won't be able to talk with it. So, we need to turn atomisp_gmin_platform into a module again, for it to not depend on atomisp driver to finish probing, and add some delay at atomisp to let the sensor driver to finish probing. Yeah, this is hacky. The real solution here would be to use the async framework, but for now, our goal is to make the driver to work. So, let's postpone such change to be done later.

2020-05-20media: atomisp: keep the ISP powered on when setting itMauro Carvalho Chehab1-2/+6
The current code causes ISP2401 to power down and never return back to live, causing the driver to crash. Fix it by commenting out the bad code. It should be noticed that the Yocto Aero code has something similar to it. Maybe the issue is related to an ISP bug (or maybe PM is controlled on a different way for this hardware).

2020-05-20media: atomisp: fix a slab error due to a wrong freeMauro Carvalho Chehab1-1/+4
The mmu mapping logic uses a different logic depending on the RAM size: if it is lower than 2GB, it uses kmem_cache_zalloc(), but if memory is bigger than that, it uses its own way to allocate memory. Yet, when freeing, it uses kmem_cache_free() for any cases. On recent Kernels, slab tracks the memory allocated on it, with causes those warnings: virt_to_cache: Object is not a Slab page!

2020-05-20media: atomisp: add support for different PMIC configurationsMauro Carvalho Chehab1-50/+225
This patch required lots of research and work. The existing atomisp driver at staging assumed that all Intel PMIC would be using regulators, but upstream didn't follow it. Instead, the intel_pmic.c driver added a hack, instead of using i2c_transfer, it writes I2C values directly via regmapped registers. Oh, well... At least, it provided a common API for doing that. The PMIC settings used here came from the driver at the yocto Aero distribution: https://download.01.org/aero/deb/pool/main/l/linux-4.4.76-aero-1.3/ The logic itself was re-written, in order to use the I2C address detected by the probing part.

2020-05-20media: atomisp: move atomisp_gmin_platform.c to pci/ dirMauro Carvalho Chehab5-11/+2
The atomisp_gmin_platform.c is not a platform driver anymore, but it is, instead, part of the atomisp driver. Move it to be together with the driver. As a bonus, as the atomisp i2c drivers depends on its contents, probing them should load automatically the atomisp core. This should likely avoid some possible race conditions.

2020-05-20media: atomisp: detect the PMIC typeMauro Carvalho Chehab1-10/+64
Sub-device's power management can be provided via different ways. Instead of hardcoding it, add a code that would be detecting it. This uses a code similar to what's found at the atomisp driver inside the Intel Aero repository: https://github.com/intel-aero/meta-intel-aero.git (driver was removed on some commit, but it can be found on git history).

2020-05-20media: atomisp: reduce the risk of a race conditionMauro Carvalho Chehab1-2/+23
This driver is really on bad shape. One of the problems is that, as soon as the I2C transfers start to happen, it timeouts detecting a camera: ov2680 i2c-OVTI2680:00: ov2680_probe: ACPI detected it on bus ID=CAM1, HID=OVTI2680 atomisp-isp2 0000:00:03.0: no camera attached or fail to detect ov2680 i2c-OVTI2680:00: gmin: initializing atomisp module subdev data using PMIC regulator ...

2020-05-20media: atomisp: fix clock rate frequency settingMauro Carvalho Chehab1-3/+11
changeset d5426f4c2eba ("media: staging: atomisp: use clock framework for camera clocks") removed a platform-specific code to set the clock rate, in favor of using the Kernel clock framework. However, instead of passing the frequency for clk_set_rate(), it is passing either 0 or 1. Looking at the original patchset, it seems that there are two possible configurations for the ISP: 0 - it will use a 25 MHz XTAL to provide the clock; 1 - it will use a PLL with is set to 19.2 MHz (only for the CHT version?) Eventually, different XTALs and/or PLL frequencies might be possible some day, so, re-implent the logic for it to be more generic.

2020-05-20media: atomisp: print a better message when fw version is wrongMauro Carvalho Chehab6-134/+21
The printed message when a firmware version is wrong says nothing usefull: atomisp-isp2 0000:00:03.0: Fw version check failed. atomisp-isp2: probe of 0000:00:03.0 failed with error -22 Print the expected and the received firmware version instead. In order to do that, the firmware functions will need at least a struct device pointer, so pass it. While writing this patch, it was noticed that some of the abstraction layers of this driver have functions that are never called, but use this interface. Get rid of them.

2020-05-20media: atomisp: fix querycap initialization logicMauro Carvalho Chehab4-58/+48
Some recent changes at V4L2 core changed the way querycap is handled. Due to that, this warning is generated: WARNING: CPU: 1 PID: 503 at drivers/media/v4l2-core/v4l2-dev.c:885 __video_register_device+0x93e/0x1120 [videodev] as introduced by this commit: commit 3c1350501c21db8e3b1a38d9e97db29694305c3b Author: Hans Verkuil <hverkuil-cisco@xs4all.nl> Date: Tue Jul 23 04:21:25 2019 -0400 media: v4l2-dev/ioctl: require non-zero device_caps, verify sane querycap results Now that all V4L2 drivers set device_caps in struct video_device, we can add a check for this to ensure all future drivers fill this in. The fix is simple: we just need to initialize dev_caps before registering the V4L2 dev. While here, solve other problems at VIDIOC_QUERYCAP ioctl.
