[PATCH v7 0/8] Add a panel API to set orientation properly
by Hsin-Yi Wang 21 Jun '22

21 Jun '22

Panels usually call drm_connector_set_panel_orientation(), which is later than drm/kms driver calling drm_dev_register(). This leads to a WARN()[1]. The orientation property is known earlier. For example, some panels parse the property through device tree during probe. The series add a panel API drm_connector_set_orientation_from_panel() for drm/kms drivers. The drivers can call the API to set panel's orientation before drm_dev_register(). Panel needs to implement .get_orientation callback to return the property.

[PATCH v7, 00/15] media: mtk-vcodec: support for M8192 decoder
by Yunfei Dong 21 Jun '22

21 Jun '22

This series adds support for mt8192 h264/vp8/vp9 decoder drivers. Firstly, refactor power/clock/interrupt interfaces for mt8192 is lat and core architecture. Secondly, add new functions to get frame buffer size and resolution according to decoder capability from scp side. Then add callback function to get/put capture buffer in order to enable lat and core decoder in parallel. Then add to support MT21C compressed mode and fix v4l2-compliance fail. Next, extract H264 request api driver to let mt8183 and mt8192 use the same code, and adds mt8192 frame based h264 driver for stateless decoder. Lastly, add vp8 and vp9 stateless decoder drivers. Patches 1 refactor power/clock/interrupt interface. Patches 2~4 get frame buffer size and resolution according to decoder capability. Patches 5~6 enable lat and core decode in parallel.

[PATCH v2] drm: shmobile: Use backlight helper
by Stephen Kitt 21 Jun '22

21 Jun '22

This started with work on the removal of backlight_properties' deprecated fb_blank field, much of which can be taken care of by using helper functions provided by backlight.h instead of directly accessing fields in backlight_properties. This patch series doesn't involve fb_blank, but it still seems useful to use helper functions where appropriate. Instead of retrieving the backlight brightness in struct backlight_properties manually, and then checking whether the backlight should be on at all, use backlight_get_brightness() which does all this and insulates this from future changes.

[PATCH v2 0/2] Improve vfio-pci primary GPU assignment behavior
by Alex Williamson 21 Jun '22

21 Jun '22

When assigning a primary graphics device to VM through vfio-pci device assignment, users often prevent binding of the native PCI graphics driver to avoid device initialization conflicts, however firmware console drivers may still be attached to the device which can often be cumbersome to manually unbind or exclude via cmdline options. This series proposes to move the DRM aperture helpers out to drivers/video/ to make it more accessible to drivers like vfio-pci, which have neither dependencies on DRM code nor a struct drm_driver to present to existing interfaces. vfio-pci can then trivially call into the aperture helpers to remove conflicting drivers, rather than open coding it ourselves as was proposed with a new symbol export in v1 of this series[1]. Thanks to Thomas for splitting out the aperture code with new documentation. Thomas had proposed this going through the vfio tree with appropriate stakeholder acks, that's fine with me, but I'm also open to it going through the DRM tree given that the vfio-pci-core change is even more trivial now and the bulk of the changes are DRM/video paths.

From: ChiaEn Wu <chiaen_wu(a)richtek.com> This patch series add Mediatek MT6370 PMIC support. The MT6370 is a highly-integrated smart power management IC, which includes a single cell Li-Ion/Li-Polymer switching battery charger, a USB Type-C & Power Delivery (PD) controller, dual Flash LED current sources, a RGB LED driver, a backlight WLED driver, a display bias driver and a general LDO for portable devices. Among with this we took some changes and refined the device tree files to comply with DT specifications. Thank you, ChiaEn Wu --- Changes in v2: - In patch 01/15: - Add "unevaluatedProperties: false". - Delete "DT bindings". - Refine the description to fit in 80 columns. - Skip the connector description. - In patch 02/15: - Refine items description of interrupt-name - Rename "usb-otg-vbus" to "usb-otg-vbus-regulator" - Add constraint properties for ADC - In patch 03/15: - Skip not useful description of "^(multi-)?led@[0-3]$" and reg. - Due to the dependency, remove the mention of mfd document directory. - Delete Soft-start property. In design aspect, we think soft-restart should always be enabled, our new chip has deleted the related setting register , also, we don’t allow user adjust this parameter in this chip. - Refine the commit message. - In patch 04/15: - Skip not useful description of "^led@[0-1]$" and reg. - Add apace after '#'. - Refine the commit message. - In patch 05/15: - Remove "binding documentation" in subject title - Refine description of mt6370 backlight binding document - Refine properties name(bled-pwm-hys-input-bit, bled-ovp-microvolt, bled-ocp-microamp) and their description - In patch 06/15: - Refine ADC and Regulator descriptions - Refine include header usage in example - Refine node name to generic node name("pmic@34") - Refine led example indentation - Refine license of mediatek,mt6370_adc.h - Rename the dts example from IRQ define to number. - Remove mediatek,mt6370.h - In patch 07/15: - Add ABI documentation for mt6370 non-standard ADC sysfs interfaces. - In patch 08/15: - Add all IRQ define into mt6370.c. - Refine include header usage - In patch 09/15: - No changes. - In patch 10/15: - Use 'gpiod_get_from_of_node' to replace 'fwnode_gpiod_get_index'. - In patch 11/15: - Refine Kconfig mt6370 help text - Refine mask&shift to FIELD_PREP() - Refine mutex lock name ("lock" -> "adc_lock") - Refine mt6370_adc_read_scale() - Refine mt6370_adc_read_offset() - Refine mt6370_channel_labels[] by using enum to index chan spec - Refine MT6370_ADC_CHAN() - Refine indio_dev->name - Remove useless include header files - In patch 12/15: - Refine mt6370_chg_otg_rdesc.of_match ("mt6370,otg-vbus" -> "usb-otg-vbus-regulator") to match DT binding - In patch 13/15: - Refine Kconfig description. - Remove include "linux/of.h" and use "linux/mod_devicetable.h". - Place a comma for the last element of the const unsigned int array. - Add a comment line for the mutex 'lock'. - In probe function, use 'dev_err_probe' in some judgement to reduce the LOC. - Refine include header usage. BIT/GENMASK -> linux/bits.h FIELD_GET -> linux/bitfield.h - In patch 14/15: - Add blank line. - Replace container_of() with to_mt6370_led() . - Refine description of ramping. - Refine the mt6370_init_common_properties function. - Refine the probe return. - In patch 15/15: - Refine MT6370 help text in Kconfig - Refine DT Parse function - Remove useless enum - Add comment for 6372 backward compatible in bl_update_status() and check_vendor_info() - Using dev_err_probe(); insteads dev_err()&return; in the probe() Alice Chen (2): dt-bindings: leds: Add Mediatek MT6370 flashlight leds: flashlight: mt6370: Add Mediatek MT6370 flashlight support ChiYuan Huang (8): dt-bindings: usb: Add Mediatek MT6370 TCPC dt-bindings: leds: mt6370: Add Mediatek mt6370 current sink type LED indicator dt-bindings: backlight: Add Mediatek MT6370 backlight dt-bindings: mfd: Add Mediatek MT6370 mfd: mt6370: Add Mediatek MT6370 support usb: typec: tcpci_mt6370: Add Mediatek MT6370 tcpci driver regulator: mt6370: Add mt6370 DisplayBias and VibLDO support leds: mt6370: Add Mediatek MT6370 current sink type LED Indicator support ChiaEn Wu (5): dt-bindings: power: supply: Add Mediatek MT6370 Charger Documentation: ABI: testing: mt6370: Add ADC sysfs guideline iio: adc: mt6370: Add Mediatek MT6370 support power: supply: mt6370: Add Mediatek MT6370 charger driver video: backlight: mt6370: Add Mediatek MT6370 support .../ABI/testing/sysfs-bus-iio-adc-mt6370 | 36 + .../backlight/mediatek,mt6370-backlight.yaml | 107 ++ .../leds/mediatek,mt6370-flashlight.yaml | 44 + .../leds/mediatek,mt6370-indicator.yaml | 48 + .../bindings/mfd/mediatek,mt6370.yaml | 279 ++++ .../power/supply/mediatek,mt6370-charger.yaml | 60 + .../bindings/usb/mediatek,mt6370-tcpc.yaml | 36 + drivers/iio/adc/Kconfig | 9 + drivers/iio/adc/Makefile | 1 + drivers/iio/adc/mt6370-adc.c | 262 ++++ drivers/leds/Kconfig | 11 + drivers/leds/Makefile | 1 + drivers/leds/flash/Kconfig | 9 + drivers/leds/flash/Makefile | 1 + drivers/leds/flash/leds-mt6370-flash.c | 657 ++++++++++ drivers/leds/leds-mt6370.c | 989 ++++++++++++++ drivers/mfd/Kconfig | 13 + drivers/mfd/Makefile | 1 + drivers/mfd/mt6370.c | 349 +++++ drivers/power/supply/Kconfig | 11 + drivers/power/supply/Makefile | 1 + drivers/power/supply/mt6370-charger.c | 1132 +++++++++++++++++ drivers/regulator/Kconfig | 8 + drivers/regulator/Makefile | 1 + drivers/regulator/mt6370-regulator.c | 388 ++++++ drivers/usb/typec/tcpm/Kconfig | 8 + drivers/usb/typec/tcpm/Makefile | 1 + drivers/usb/typec/tcpm/tcpci_mt6370.c | 212 +++ drivers/video/backlight/Kconfig | 9 + drivers/video/backlight/Makefile | 1 + drivers/video/backlight/mt6370-backlight.c | 339 +++++ .../dt-bindings/iio/adc/mediatek,mt6370_adc.h | 18 + 32 files changed, 5042 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-bus-iio-adc-mt6370 create mode 100644 Documentation/devicetree/bindings/leds/backlight/mediatek,mt6370-backlight.yaml create mode 100644 Documentation/devicetree/bindings/leds/mediatek,mt6370-flashlight.yaml create mode 100644 Documentation/devicetree/bindings/leds/mediatek,mt6370-indicator.yaml create mode 100644 Documentation/devicetree/bindings/mfd/mediatek,mt6370.yaml create mode 100644 Documentation/devicetree/bindings/power/supply/mediatek,mt6370-charger.yaml create mode 100644 Documentation/devicetree/bindings/usb/mediatek,mt6370-tcpc.yaml create mode 100644 drivers/iio/adc/mt6370-adc.c create mode 100644 drivers/leds/flash/leds-mt6370-flash.c create mode 100644 drivers/leds/leds-mt6370.c create mode 100644 drivers/mfd/mt6370.c create mode 100644 drivers/power/supply/mt6370-charger.c create mode 100644 drivers/regulator/mt6370-regulator.c create mode 100644 drivers/usb/typec/tcpm/tcpci_mt6370.c create mode 100644 drivers/video/backlight/mt6370-backlight.c create mode 100644 include/dt-bindings/iio/adc/mediatek,mt6370_adc.h -- 2.25.1
