Patch 1/2 mentions reset-gpio polarity in DT binding example. Patch 2/2 fixes the logical value of reset-gpio during power-on/power-off sequence. --- Changes in v4: - rework 2/2 commit message - Explain conclusions for 2/2 patch, in the '---' section. Changes in v3: - Rework 1/2 commit message - Fix gpio include in DT example in 1/2 - Remove not-so-informative XCLR comment in 2/2 Changes in v2: - Also include reset-gpio polarity, mention in DT binding - Add Fixes tag in 2/2 - Set the reset line to high during init time in 2/2 Link to v2: https://lore.kernel.org/linux-media/20240729110437.199428-1-umang.jain@ideasonboard.com/ Link to v1: https://lore.kernel.org/linux-media/tyo5etjwsfznuk6vzwqmcphbu4pz4lskrg3fjieojq5qc3mg6s@6jbwavmapwmf/T/#m189ccfa77ddceda6c3b29be3306f1a27ed0934d6 Signed-off-by: Umang Jain --- Umang Jain (2): dt-bindings: media: imx335: Add reset-gpios to the DT example media: imx335: Fix reset-gpio handling Documentation/devicetree/bindings/media/i2c/sony,imx335.yaml | 4 ++++ drivers/media/i2c/imx335.c | 9 ++++----- 2 files changed, 8 insertions(+), 5 deletions(-) --- base-commit: 393556c9f56ced8d9776c32ce99f34913cfd904e change-id: 20240830-imx335-vflip-7f5d4b4d00fe Best regards,
