Why are you mapping individual registers? At least half of these are
continuous.
Hi, this is by design because of the register placement in the gpio
block and the fact that the pwm functionality is intermixed in there
also. As example the following registers are all GPIOCTRL:
<0x0 0x1fbf0200 0x0 0x4>,
<0x0 0x1fbf0220 0x0 0x4>,
<0x0 0x1fbf0260 0x0 0x4>,
<0x0 0x1fbf0264 0x0 0x4>,
To simplify the driver code logic the complexity is moved to the dts
because of that.
