From: Sunyun Yang <[email protected]> This series introduces: - A device tree binding YAML file describing the hardware - A new DRM bridge driver implementing the basic functionality
LT9611C(EX/UXD) is an I2C-controlled chip that Receiver signal/dual port mipi dsi and output hdmi, differences in hardware features: - LT9611C: supports 1-port mipi dsi to hdmi 1.4 - LT9611EX: supports 2-port mipi dsi to hdmi 1.4 - LT9611UXD: supports 2-port mipi dsi to hdmi 1.4/2.0 Signed-off-by: Sunyun Yang<[email protected]> --- Changes in v4: - dt-binding: 1. fix commit message [Krzysztof] - drm/bridge: 1. use lt9611c_fw.bin [Dmitry] 2. use drm_bridge::next_bridge 3. use enum lt9611_chip_type 4. remove *fw from the lt9611c struct 5. "bool hdmi_connected;" variable add comment 6. use read_poll_timeout and -ETIMEDOUT in the "lt9611c_read_write_flow" function 7. replace mutex_lock(<9611c->ocm_lock) with guard(mutex)(<9611c->ocm_lock) in some place 8. switch to ARRAY_SIZE instead of specifying lengths directly 9. use dev_err_probe 10. add clear functions for AVI and audio infoframes 11. add DRM_BRIDGE_OP_HDMI and remove .hpd_notify 12. remove the sample_rate validation code 13. fix MODULE_DESCRIPTION 14. replace "GPL v2" with "GPL" - Link to v3: https://lore.kernel.org/lkml/[email protected]/ Changes in v3: - dt-binding: 1. lt9611c(ex/uxd) content merged into lontium,lt9611.yaml - drm/bridge: 1. Drop the licence text, only use SPDX header 2. Sort the headers 3. Use library functions for crc8 4. Drop i2c_read_byte and i2c_write_byte 5. Lowercase all hex values 6. Use paged writes as implemented for LT9611C(EX/UXD) 7. Drop dev_info, use dev_dbg 8. Modify lt9611c_get_edid_block, don't store EDID in the long-term structures 9. Use HDMI audio helpers. 10.Remove unnecessary flags,Implement proper cleanup path, unwinding resources one by one. 11.Replace devm_kzalloc with devm_drm_bridge_alloc. 12.Remove extra kthread. - Link to v1: https://lore.kernel.org/lkml/[email protected]/ Changes in v2: 1. Forget modify code, operation error, Please disregard this submit. Changes in v1: - dt-binding: 1. Submit the first version of the code. - drm/bridge: 1. Submit the first version of the code. --- Sunyun Yang (2): dt-bindings: bridge: Add Lontium LT9611C(EX/UXD) MIPI DSI to HDMI driver drm/bridge: Add Lontium LT9611C(EX/UXD) MIPI DSI to HDMI driver .../display/bridge/lontium,lt9611.yaml | 8 +- drivers/gpu/drm/bridge/Kconfig | 18 + drivers/gpu/drm/bridge/Makefile | 1 + drivers/gpu/drm/bridge/lontium-lt9611c.c | 1211 +++++++++++++++++ 4 files changed, 1236 insertions(+), 2 deletions(-) create mode 100644 drivers/gpu/drm/bridge/lontium-lt9611c.c -- 2.34.1
