* merge patches from rockchip and rk322x families for current and edge kernels * adjust patches for tinkerboard to remove some cruft and overclocking * rework kernel configs * fix rk322x dmc to avoid lockup on rk3288 * migrate rockchip-6.6 into patch series, rename all patches with more understandable names * add gen-series.sh script in tools directory (it is a naive tool to create patch series when you don't want to rebase everything)

Subject: [PATCH 06/28] ARM: dts: rockchip: add the MiQi board's fan definition
|
|
|
|
The MiQi board is sold with an enclosure in which a fan is connected
|
|
to the second LED output, and configured by default in "heartbeat"
|
|
mode so that it rotates slowly and increases when the CPU load
|
|
increases, ensuring appropriate cooling by default. This LED output
|
|
is called "Fan" in the original kernel and connected to GPIO18
|
|
(gpiochip 0, pin 18). Here we called it "miqi:green:fan" to stay
|
|
consistent with the kernel's naming conventions.
|
|
|
|
It's worth noting that without this patch the fan doesn't work at
|
|
all, risking to make the board overheat.
|
|
