Re: [PATCH] pinctrl: rockchip: rk3328: rk3328_mux_recalced_data: fix bit alignment

here is a fun and easy way to prove how broken the current calculation is using both of the bug reports i have made combined together

using a unmodified kernel with an unmodified dtb, take note of the grf iomux gpio2b registers, it should look like this

00000200 00000001

then modifiy the device tree, change the mode of the otp-out pin from 1 to 2 and then reboot and check the registers again, they will look like this

00000200 00000002

now if you've been playing along, you will be aware that the second 32 bit chunk represents the high-side of gpio2b, which is only pin 7, but otp-out is pin 5, which resides in the first 32 bit chunk which represents the low-side of gpio2b

you can try this on any rk3328 based device
