Rockchip SoCs use 2 different numbering schemes. Where the gpio- controllers just count 0-31 for their 32 gpios, the underlying iomux controller splits these into 4 separate entities A-D. Device-schematics always use these iomux-values to identify pins, so to make mapping schematics to devicetree easier Andy Yan introduced named constants for the pins but so far we only used them on new additions. Using a sed-script created by Emil Renner Berthing bulk-convert the remaining raw gpio numbers into their descriptive counterparts and also gets rid of the unhelpful RK_FUNC_x -> x and RK_GPIOx -> x mappings: /rockchip,pins *=/bcheck b # to end of script :append-next-line N :check /^[^;]*$/bappend-next-line s/<RK_GPIO\([0-9]\) /<\1 /g s/<\([^ ][^ ]* *\)0 /<\1RK_PA0 /g s/<\([^ ][^ ]* *\)1 /<\1RK_PA1 /g s/<\([^ ][^ ]* *\)2 /<\1RK_PA2 /g s/<\([^ ][^ ]* *\)3 /<\1RK_PA3 /g s/<\([^ ][^ ]* *\)4 /<\1RK_PA4 /g s/<\([^ ][^ ]* *\)5 /<\1RK_PA5 /g s/<\([^ ][^ ]* *\)6 /<\1RK_PA6 /g s/<\([^ ][^ ]* *\)7 /<\1RK_PA7 /g s/<\([^ ][^ ]* *\)8 /<\1RK_PB0 /g s/<\([^ ][^ ]* *\)9 /<\1RK_PB1 /g s/<\([^ ][^ ]* *\)10 /<\1RK_PB2 /g s/<\([^ ][^ ]* *\)11 /<\1RK_PB3 /g s/<\([^ ][^ ]* *\)12 /<\1RK_PB4 /g s/<\([^ ][^ ]* *\)13 /<\1RK_PB5 /g s/<\([^ ][^ ]* *\)14 /<\1RK_PB6 /g s/<\([^ ][^ ]* *\)15 /<\1RK_PB7 /g s/<\([^ ][^ ]* *\)16 /<\1RK_PC0 /g s/<\([^ ][^ ]* *\)17 /<\1RK_PC1 /g s/<\([^ ][^ ]* *\)18 /<\1RK_PC2 /g s/<\([^ ][^ ]* *\)19 /<\1RK_PC3 /g s/<\([^ ][^ ]* *\)20 /<\1RK_PC4 /g s/<\([^ ][^ ]* *\)21 /<\1RK_PC5 /g s/<\([^ ][^ ]* *\)22 /<\1RK_PC6 /g s/<\([^ ][^ ]* *\)23 /<\1RK_PC7 /g s/<\([^ ][^ ]* *\)24 /<\1RK_PD0 /g s/<\([^ ][^ ]* *\)25 /<\1RK_PD1 /g s/<\([^ ][^ ]* *\)26 /<\1RK_PD2 /g s/<\([^ ][^ ]* *\)27 /<\1RK_PD3 /g s/<\([^ ][^ ]* *\)28 /<\1RK_PD4 /g s/<\([^ ][^ ]* *\)29 /<\1RK_PD5 /g s/<\([^ ][^ ]* *\)30 /<\1RK_PD6 /g s/<\([^ ][^ ]* *\)31 /<\1RK_PD7 /g s/<\([^ ][^ ]* *[^ ][^ ]* *\)0 /<\1RK_FUNC_GPIO /g s/<\([^ ][^ ]* *[^ ][^ ]* *\)RK_FUNC_\([1-9]\) /<\1\2 /g Suggested-by: Emil Renner Berthing <esmil@mailme.dk> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Tested-by: Katsuhiro Suzuki <katsuhiro@katsuster.net> Acked-by: Robin Murphy <robin.murphy@arm.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
