- *	This driver allows use of the real time clock (built into

- *
- *	The ioctls can be used to set the interrupt behaviour where

- *
- *	The /dev/rtc interface will block on reads until an interrupt
- *	has been received. If a RTC interrupt has already happened,
- *	it will output an unsigned long and then block. The output value
- *	contains the interrupt status in the low byte and the number of
- *	interrupts since the last read in the remaining high bytes. The
- *	/dev/rtc interface can also be used with the select(2) call.

- * DMA driver for Xilinx Video DMA Engine
- *
- * Copyright (C) 2010-2014 Xilinx, Inc. All rights reserved.
- *
- * Based on the Freescale DMA driver.
- *
- * Description:
- * The AXI Video Direct Memory Access (AXI VDMA) core is a soft Xilinx IP
- * core that provides high-bandwidth direct memory access between memory
- * and AXI4-Stream type video target peripherals. The core provides efficient
- * two dimensional DMA operations with independent asynchronous read (S2MM)
- * and write (MM2S) channel operation. It can be configured to have either
- * one channel or two channels. If configured as two channels, one is to
- * transmit to the video device (MM2S) and another is to receive from the
- * video device (S2MM). Initialization, status, interrupt and management
- * registers are accessed through an AXI4-Lite slave interface.
- *
- * The AXI Direct Memory Access (AXI DMA) core is a soft Xilinx IP core that
- * provides high-bandwidth one dimensional direct memory access between memory
- * and AXI4-Stream target peripherals. It supports one receive and one
- * transmit channel, both of them optional at synthesis time.
- *
- * The AXI CDMA, is a soft IP, which provides high-bandwidth Direct Memory
- * Access (DMA) between a memory-mapped source address and a memory-mapped
- * destination address.
- *
- * This program is free software: you can redistribute it and/or modify
- * it under the terms of the GNU General Public License as published by
- * the Free Software Foundation, either version 2 of the License, or

- * Modularized and updated for 1.1.16 kernel - Mitch Dsouza 28th May 1994
- * Adapted for 1.3.59 kernel - Andries Brouwer, 1 Feb 1996
- *
- * Fixed do_loop_request() re-entrancy - Vincent.Renardias@waw.com Mar 20, 1997
- *
- * Added devfs support - Richard Gooch <rgooch@atnf.csiro.au> 16-Jan-1998
- *
- * Handle sparse backing files correctly - Kenn Humborg, Jun 28, 1998
- *
- * Loadable modules and other fixes by AK, 1998
- *
- * Maximum number of loop devices now dynamic via max_loop module parameter.
- * Russell Kroll <rkroll@exploits.org> 19990701
- *
- * Maximum number of loop devices when compiled-in now selectable by passing
- * max_loop=<1-255> to the kernel on boot.
- * Erik I. Bols?, <eriki@himolde.no>, Oct 31, 1999
- *
- * Completely rewrite request handling to be make_request_fn style and
- * non blocking, pushing work to a helper thread. Lots of fixes from
- * Al Viro too.
- * Jens Axboe <axboe@suse.de>, Nov 2000
- *
- * Support up to 256 loop devices
- * Heinz Mauelshagen <mge@sistina.com>, Feb 2002
- *
- * Support for falling back on the write file operation when the address space
- * operations prepare_write and/or commit_write are not available on the
- * backing filesystem.
- * Anton Altaparmakov, 16 Feb 2005
- *
- * Still To Fix:
- * - Advisory locking is ignored here.
- * - Should use an own CAP_* category instead of CAP_SYS_ADMIN

-	 * 1. Define a new operation in cl_object_operations{}, says clo_depth,

-	 *    speaking, the depth would be 2, one for llite, and one for lovsub.
-	 *    However, for SNS, there will be more since we need additional page
-	 *    to store parity;
-	 * 2. Reserve the # of (page_count * depth) cl_pages from the reserved
-	 *    pool. Afterwards, the clio would allocate the pages from reserved
-	 *    pool, this guarantees we needn't allocate the cl_pages from
-	 *    generic cl_page slab cache.
-	 *    Of course, if there is NOT enough pages in the pool, we might
-	 *    be asked to write less pages once, this purely depends on
-	 *    implementation. Anyway, we should be careful to avoid deadlocking.

-Driver general quality is not good enough for mainline. Also, other
-device drivers (USB-bridge, tuner) needed for Astrometa receiver in
-question could need some changes. However, if that driver is mainlined
-due to some other device than Astrometa, unrelated TODOs could be
-skipped. In that case rtl28xxu driver needs module parameter to prevent
-driver loading.
-
-Required TODOs:
-* missing lock flags
-* I2C errors
-* tuner sensitivity
-
-*Do not* send any patch fixing checkpatch.pl issues. Currently it passes
-checkpatch.pl tests. I don't want waste my time to review this kind of
-trivial stuff. *Do not* add missing register I/O error checks. Those are
-missing for the reason it is much easier to compare I2C data sniffs when
-there is less lines. Those error checks are about the last thing to be added.
-
-Patches should be submitted to:
-linux-media@vger.kernel.org and Antti Palosaari <crope@iki.fi>
