Subject: [PATCH v2 00/15] media: microchip-isc: fixes and enhancements
Date: Tue, 12 May 2026 21:13:24 +0530 [thread overview]
Message-ID: <20260512154339.210444-1-balakrishnan.s@microchip.com> (raw)
In-Reply-To: <20251009155251.102472-1-balamanikandan.gunasundar@microchip.com>
Bug fixes and feature additions for the Microchip ISC/XISC driver.
Fixes:
- SBGGR10 Bayer pattern was mapped incorrectly (red/blue swap)
- WB register fields corrupted by sign extension
- Race between histogram IRQ and stream stop
- PM runtime reference leak in AWB work handler
Features:
- Driver documentation
- Gamma 1.8/2.4 curves, per-channel gamma LUT
- Hue/saturation controls for SAMA7G5
- Color correction matrix controls
- Grey World AWB with EMA smoothing
Split from v1 per review. Histogram stats follow as Series 2.
Tested on SAMA7G5-EK with IMX219 (RAW10 Bayer capture, AWB, color
controls verified). Build tested with COMPILE_TEST and W=1. All
patches pass checkpatch --strict.
Based on v6.19-rc8 (18f7fcd5e69a).
v1: https://lore.kernel.org/linux-media/20251009155251.102472-1-balamanikandan.gunasundar@microchip.com/
v2:
- Split series (histogram stats moved to Series 2)
- Bug fixes first, then features
- New fixes and features as listed above
- Commit message cleanups
- Rebased on v6.19-rc8
