2019-09-16media: cec/v4l2: move V4L2 specific CEC functions to V4L2Hans Verkuil2-3/+3
[ 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. The problem was that if the CEC_CORE config option was not set, then these functions would become stubs, but that's not right: they should always be valid. So replace the cec_ prefix by v4l2_ and move them to v4l2-dv-timings.c. Update all drivers that call these accordingly.

2019-09-06omap-dma/omap_vout_vrfb: fix off-by-one fi valueHans Verkuil1-2/+1
[ Upstream commit d555c34338cae844b207564c482e5a3fb089d25e ] The OMAP 4 TRM specifies that when using double-index addressing the address increases by the ES plus the EI value minus 1 within a frame. When a full frame is transferred, the address increases by the ES plus the frame index (FI) value minus 1. The omap-dma code didn't account for the 'minus 1' in the FI register. To get correct addressing, add 1 to the src_icg value. This was found when testing a hacked version of the media m2m-deinterlace.c driver on a Pandaboard. The only other source that uses this feature is omap_vout_vrfb.c, and that adds a + 1 when setting the dst_icg. This is a workaround for the broken omap-dma.c behavior. So remove the workaround at the same time that we fix omap-dma.c. I tested the omap_vout driver with a Beagle XM board to check that the '+ 1' in omap_vout_vrfb.c was indeed a workaround for the omap-dma bug.

2019-07-26media: coda: fix last buffer handling in V4L2_ENC_CMD_STOPMarco Felsch1-0/+2
[ Upstream commit f3775f89852d167990b0d718587774cf00d22ac2 ] coda_encoder_cmd() is racy, as the last scheduled picture run worker can still be in-flight while the ENC_CMD_STOP command is issued. Depending on the exact timing the sequence numbers might already be changed, but the last buffer might not have been put on the destination queue yet. In this case the current implementation would prematurely wake the destination queue with last_buffer_dequeued=true, causing userspace to call streamoff before the last buffer is handled. Close this race window by synchronizing with the pic_run_worker before doing the sequence check.

[ Upstream commit c5ff0edb8e2270a75935c73217fb0de1abd2d910 ] There is a block of code in rvin_group_link_notify() that prevents enabling a link to a VIN node if any entity in the media graph is in use. This prevents enabling a VIN link even if there is an in-use entity somewhere in the graph that is independent of the link's pipeline. For example, the code block will prevent enabling a link from the first rcar-csi2 receiver to a VIN node even if there is an enabled link somewhere far upstream on the second independent rcar-csi2 receiver pipeline. If this code block is meant to prevent modifying a link if any entity in the graph is actively involved in streaming (because modifying the CHSEL register fields can disrupt any/all running streams), then the entities stream counts should be checked rather than the use counts. (There is already such a check in __media_entity_setup_link() that verifies the stream_count of the link's source and sink entities are both zero, but that is insufficient, since there should be no running streams in the entire graph). Modify the code block to check the entity stream_count instead of the use_count (and elaborate on the comment). VIN node links can now be enabled even if there are other independent in-use entities that are not streaming.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc Pull char/misc driver updates from Greg KH: "Here is the bit set of char/misc drivers for 4.19-rc1 There is a lot here, much more than normal, seems like everyone is writing new driver subsystems these days... Anyway, major things here are: - new FSI driver subsystem, yet-another-powerpc low-level hardware bus - gnss, finally an in-kernel GPS subsystem to try to tame all of the crazy out-of-tree drivers that have been floating around for years, combined with some really hacky userspace implementations. This is only for GNSS receivers, but you have to start somewhere, and this is great to see. Other than that, there are new slimbus drivers, new coresight drivers, new fpga drivers, and loads of DT bindings for all of these and existing drivers. All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (255 commits) android: binder: Rate-limit debug and userspace triggered err msgs fsi: sbefifo: Bump max command length fsi: scom: Fix NULL dereference misc: mic: SCIF Fix scif_get_new_port() error handling misc: cxl: changed asterisk position genwqe: card_base: Use true and false for boolean values misc: eeprom: assignment outside the if statement uio: potential double frees if __uio_register_device() fails eeprom: idt_89hpesx: clean up an error pointer vs NULL inconsistency misc: ti-st: Fix memory leak in the error path of probe() android: binder: Show extra_buffers_size in trace firmware: vpd: Fix section enabled flag on vpd_section_destroy platform: goldfish: Retire pdev_bus goldfish: Use dedicated macros instead of manual bit shifting goldfish: Add missing includes to goldfish.h mux: adgs1408: new driver for Analog Devices ADGS1408/1409 mux dt-bindings: mux: add adi,adgs1408 Drivers: hv: vmbus: Cleanup synic memory free path Drivers: hv: vmbus: Remove use of slow_virt_to_phys() Drivers: hv: vmbus: Reset the channel callback in vmbus_onoffer_rescind() ...

Without the MFD driver, we run into a link error: drivers/media/platform/cros-ec-cec/cros-ec-cec.o: In function `cros_ec_cec_transmit': cros-ec-cec.c:(.text+0x474): undefined reference to `cros_ec_cmd_xfer_status' drivers/media/platform/cros-ec-cec/cros-ec-cec.o: In function `cros_ec_cec_set_log_addr': cros-ec-cec.c:(.text+0x60b): undefined reference to `cros_ec_cmd_xfer_status' drivers/media/platform/cros-ec-cec/cros-ec-cec.o: In function `cros_ec_cec_adap_enable': cros-ec-cec.c:(.text+0x77d): undefined reference to `cros_ec_cmd_xfer_status' As we can compile-test all the dependency, the extra '| COMPILE_TEST' is not needed to get the build coverage, and we can simply turn MFD_CROS_EC into a hard dependency to make it build in all configurations.
