- * Based on:
- * - linux/drivers/video/artistfb.c -- Artist frame buffer driver
- * Copyright (C) 2000 Philipp Rumpf <prumpf@tux.org>
- * - based on skeletonfb, which was

- * The following graphics display devices (NGLE family) are supported by this driver:
- *
- * HPA4070A known as "HCRX", a 1280x1024 color device with 8 planes
- * HPA4071A known as "HCRX24", a 1280x1024 color device with 24 planes,
- * optionally available with a hardware accelerator as HPA4071A_Z
- * HPA1659A known as "CRX", a 1280x1024 color device with 8 planes
- * HPA1439A known as "CRX24", a 1280x1024 color device with 24 planes,
- * optionally available with a hardware accelerator.
- * HPA1924A known as "GRX", a 1280x1024 grayscale device with 8 planes
- * HPA2269A known as "Dual CRX", a 1280x1024 color device with 8 planes,
- * implements support for two displays on a single graphics card.
- * HP710C internal graphics support optionally available on the HP9000s710 SPU,
- * supports 1280x1024 color displays with 8 planes.
- * HP710G same as HP710C, 1280x1024 grayscale only
- * HP710L same as HP710C, 1024x768 color only
- * HP712 internal graphics support on HP9000s712 SPU, supports 640x480,
- * 1024x768 or 1280x1024 color displays on 8 planes (Artist)
