Subject: [PATCH RESEND v7 6/7] drm: atmel-hlcdc: add vertical and horizontal scaling support for XLCDC
Date: Mon, 29 Jan 2024 14:53:18 +0530	[thread overview]
Message-ID: <20240129092319.199365-7-manikandan.m@microchip.com> (raw)
In-Reply-To: <20240129092319.199365-1-manikandan.m@microchip.com>

Update the LCDC_HEOCFG30 and LCDC_HEOCFG31 registers of XLCDC IP which
supports vertical and horizontal scaling with Bilinear and Bicubic
co-efficients taps for Chroma and Luma componenets of the Pixel.
