Handling timing parameters in a driver's own way should be avoided
because it duplicates efforts of drivers/mtd/nand/nand_timings.c
Besides, this driver hard-codes Intel specific parameters such as
CLK_X=5, CLK_MULTI=4. Taking a certain device (Samsung K9WAG08U1A)
into account by get_samsung_nand_para() is weird as well.
Now, the core framework provides .setup_data_interface() hook, which
handles timing parameters in a generic manner.
While I am working on this, I found even more issues in the current
code, so fixed the following as well:
- In recent IP versions, WE_2_RE and TWHR2 share the same register.
Likewise for ADDR_2_DATA and TCWAW, CS_SETUP_CNT and TWB. When
updating one, the other must be masked. Otherwise, the other will
be set to 0, then timing settings will be broken.
- The recent IP release expanded the ADDR_2_DATA to 7-bit wide.
This register is related to tADL. As commit

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
