2021-09-23arm64: dts: rockchip: add phandles to muxed i2c buses on rk3368-lionJakob Unterwurzacher
Other DTS files that include the dtsi will want to to add children to the i2c buses from the i2c-mus. Without a label they would have to specify the full path.

2021-04-11arm64: dts: rockchip: move mmc aliases to board dts on rk3368Heiko Stuebner
As suggested by Arnd Bergmann, the newly added mmc aliases should be board specific, so move them from the general dtsi to the individual boards.

2020-06-17arm64: dts: rockchip: rename and label gpio-led subnodes part 2Johan Jonker
Current dts files with 'gpio-led' nodes were manually verified. In order to automate this process leds-gpio.txt has been converted to yaml. With this conversion a check for pattern properties was added. In part 2 rename and label gpio-led subnodes that passed the regex, but still don't have the preferred form. Any pin subnode that ends with '-gpio' in the pinctrl node generates a warning. Fix with help of the following rules: 1: Add nodename in the preferred form. 2: Always add a label that ends with '_led' to prevent conflicts with other labels such as 'power' and 'mmc' 3: If leds need pinctrl add a label that ends with '_led_pin' also to prevent conflicts with other labels. patternProperties: # The first form is preferred, but fall back to just 'led' # anywhere in the node name to at least catch some child nodes.

2020-06-17arm64: dts: rockchip: fix rk3368-lion gmac reset gpioHeiko Stuebner
The lion gmac node currently uses opposite active-values for the gmac phy reset pin. The gpio-declaration uses active-high while the separate snps,reset-active-low property marks the pin as active low. While on the kernel side this works ok, other DT users may get confused - as seen with uboot right now. So bring this in line and make both properties match, similar to the other Rockchip board.

2019-04-28dt-bindings: hwmon (pwm-fan) Remove dead "cooling-*-state" propertiesRobin Murphy
The old "cooling-{min,max}-state" properties for thermal bindings were ratified to "cooling-{min,max}-level" by commit eb168b70dea5 ("of: thermal: Fix inconsitency between cooling-*-state and cooling-*-level"), which were later removed entirely by commit e04907dbc259 ("dt-bindings: thermal: Remove "cooling-{min|max}-level" properties"). The pwm-fan binding, however, was apparently in-flight in parallel with that ratification, and so managed to introduce an example of the old properties which escaped the scope of the later cleanup and has thus continued to be dutifully copied for new boards despite being useless. Clean up these remaining undocumented anachronisms to minimise any further confusion.

2019-04-11arm64: dts: rockchip: bulk convert gpios to their constant counterpartsHeiko Stuebner
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>
