2022-04-13staging: wfx: fix an error handling in wfx_init_common()Xiaoke Wang1-1/+6
[ Upstream commit 60f1d3c92dc1ef1026e5b917a329a7fa947da036 ] One error handler of wfx_init_common() return without calling ieee80211_free_hw(hw), which may result in memory leak. And I add one err label to unify the error handler, which is useful for the subsequent changes.

off on some boards [ Upstream commit 2c39a01154ea57d596470afa1d278e3be3b37f6a ] The TrekStor SurfTab duo W1 10.1 has a hw bug where turning eldo2 back on after having turned it off causes the CPLM3218 ambient-light-sensor on the front camera sensor's I2C bus to crash, hanging the bus. Add a DMI quirk table for systems on which to leave eldo2 on. Note an alternative fix is to turn off the CPLM3218 ambient-light-sensor as long as the camera sensor is being used, this is what Windows seems to do as a workaround (based on analyzing the DSDT). But that is not easy to do cleanly under Linux.

[ Upstream commit c8c80c996182239ff9b05eda4db50184cf3b2e99 ] As the possible failure of the kzalloc(), the 'new_ts' could be NULL pointer. Therefore, it should be better to check it in order to avoid the dereference of the NULL pointer. Also, the caller esparser_queue() needs to deal with the return value of the amvdec_add_ts().

[ Upstream commit 2c45e343c581091835c9047ed5298518aa133163 ] The atomisp driver originally used the s_parm command to initialize the run_mode type to the driver. So, before start setting up the streaming, s_parm should be called. So, even having 5 "normal" video devices, one meant to be used for each type, the run_mode was actually selected when s_parm is called. Without setting the run mode, applications that don't call VIDIOC_SET_PARM with a custom atomisp parameters won't work, as the pipeline won't be set: atomisp-isp2 0000:00:03.0: can't create streams atomisp-isp2 0000:00:03.0: __get_frame_info 1600x1200 (padded to 0) returned -22 However, commit 8a7c5594c020 ("media: v4l2-ioctl: clear fields in s_parm") broke support for it, with a good reason, as drivers shoudn't be extending the API for their own purposes. So, as an step to allow generic apps to use this driver, put the device's run_mode in preview after open. After this patch, using v4l2grab starts to work on preview mode (/dev/video2): $ v4l2grab -f YUYV -x 1600 -y 1200 -d /dev/video2 -n 1 -u $ feh out000.pnm So, let's just setup the default run_mode that each video devnode should assume, setting it at open() time.

[ Upstream commit 2e81948177d769106754085c3e03534e6cc1f623 ] As the possible alloc failure of devm_kcalloc(), it could return null pointer. Therefore, 'strings' should be checked and return NULL if alloc fails to prevent the dereference of the NULL pointer. Also, the caller should also deal with the return value of the gb_generate_enum_strings() and return -ENOMEM if returns NULL. Moreover, because the memory allocated with devm_kzalloc() will be freed automatically when the last reference to the device is dropped, the 'gbe' in gbaudio_tplg_create_enum_kctl() and gbaudio_tplg_create_enum_ctl() do not need to free manually. But the 'control' in gbaudio_tplg_create_widget() and gbaudio_tplg_process_kcontrols() has a specially error handle to cleanup. So it should be better to cleanup 'control' when fails.

2022-01-27media: hantro: Hook up RK3399 JPEG encoder outputChen-Yu Tsai4-4/+23
[ Upstream commit 230d683ae04894933720425c8dead9508a09ebc3 ] The JPEG encoder found in the Hantro H1 encoder block only produces a raw entropy-encoded scan. The driver is responsible for building a JPEG compliant bitstream and placing the entropy-encoded scan in it. Right now the driver uses a bounce buffer for the hardware to output the raw scan to. In commit e765dba11ec2 ("hantro: Move hantro_enc_buf_finish to JPEG codec_ops.done"), the code that copies the raw scan from the bounce buffer to the capture buffer was moved, but was only hooked up for the Hantro H1 (then RK3288) variant. The RK3399 variant was broken, producing a JPEG bitstream without the scan, and the capture buffer's .bytesused field unset. Fix this by duplicating the code that is executed when the JPEG encoder finishes encoding a frame. As the encoded length is read back from hardware, and the variants having different register layouts, the code is duplicated rather than shared.

2022-01-27media: atomisp: fix ifdefs in sh_css.cTsuchiya Yuto1-16/+11
[ Upstream commit 5a1b2725558f8a3b4cbf0504f53cffae8e163034 ] ## `if (pipe->stream->config.mode == IA_CSS_INPUT_MODE_TPG) {` case The intel-aero atomisp has `#if defined(IS_ISP_2400_SYSTEM)` [1]. It is to be defined in the following two places [2]: - css/hive_isp_css_common/system_global.h - css/css_2401_csi2p_system/system_global.h and the former file is to be included on ISP2400 devices, too. So, it is to be defined for both ISP2400 and ISP2401 devices. Because the upstreamed atomisp driver now supports only ISP2400 and ISP2401, just remove the ISP version test again. This matches the other upstream commits like 3c0538fbad9f ("media: atomisp: get rid of most checks for ISP2401 version"). While here, moved the comment for define GP_ISEL_TPG_MODE to the appropriate place. [1] https://github.com/intel-aero/linux-kernel/blob/a1b673258feb915268377275130c5c5df0eafc82/drivers/media/pci/atomisp/css/sh_css.c#L552-L558 [2] https://github.com/intel-aero/linux-kernel/search?q=IS_ISP_2400_SYSTEM ## `isys_stream_descr->polling_mode` case This does not exist on the intel-aero atomisp. This is because it is based on css version irci_stable_candrpv_0415_20150521_0458. On the other hand, the upstreamed atomisp is based on the following css version depending on the ISP version using ifdefs: - ISP2400: irci_stable_candrpv_0415_20150521_0458 - ISP2401: irci_master_20150911_0724 The `isys_stream_descr->polling_mode` usage was added on updating css version to irci_master_20150701_0213 [3]. So, it is not a ISP version specific thing, but css version specific thing. Because the upstreamed atomisp driver uses irci_master_20150911_0724 for ISP2401, re-add the ISP version check for now. I say "for now" because ISP2401 should eventually use the same css version with ISP2400 (i.e., irci_stable_candrpv_0415_20150521_0458) [3] https://raw.githubusercontent.com/intel/ProductionKernelQuilts/cht-m1stable-2016_ww31/uefi/cht-m1stable/patches/cam-0439-atomisp2-css2401-and-2401_legacy-irci_master_2015070.patch ("atomisp2: css2401 and 2401_legacy-irci_master_20150701_0213") Link to Intel's Android kernel patch. ## `coord = &me->config.internal_frame_origin_bqs_on_sctbl;` case it was added on commit 4f744a573db3 ("media: atomisp: make sh_css_sp_init_pipeline() ISP version independent") for ISP2401. Because the upstreamed atomisp for the ISP2401 part is based on irci_master_20150911_0724, hence the difference. Because the upstreamed atomisp driver uses irci_master_20150911_0724 for ISP2401, revert the test back to `if (IS_ISP2401)`.

2022-01-27media: atomisp: fix punit_ddr_dvfs_enable() argument for mrfld_power up caseTsuchiya Yuto1-4/+4
[ Upstream commit 5bfbf65fcca7325e4d89d289b3c286e11220e386 ] When comparing with intel-aero atomisp [1], it looks like punit_ddr_dvfs_enable() should take `false` as an argument on mrfld_power up case. Code from the intel-aero kernel [1]: int atomisp_mrfld_power_down(struct atomisp_device *isp) { [...] /*WA:Enable DVFS*/ if (IS_CHT) punit_ddr_dvfs_enable(true); int atomisp_mrfld_power_up(struct atomisp_device *isp) { [...] /*WA for PUNIT, if DVFS enabled, ISP timeout observed*/ if (IS_CHT) punit_ddr_dvfs_enable(false); This patch fixes the inverted argument as per the intel-aero code, as well as its comment. While here, fix space issues for comments in atomisp_mrfld_power(). Note that it does not seem to be possible to unify the up/down cases for punit_ddr_dvfs_enable(), i.e., we can't do something like the following: if (IS_CHT) punit_ddr_dvfs_enable(!enable); because according to the intel-aero code [1], the DVFS is disabled before "writing 0x0 to ISPSSPM0 bit[1:0]" and the DVFS is enabled after "writing 0x3 to ISPSSPM0 bit[1:0]".
