The patch was born from the need to change the slew rate of the LCD pins of a custom AM335x board during EMC tests. The AM335x, as described in a note in section 9.1 of its reference manual [1], is unable to write pinmux registers from user space. The series now makes it possible to write these registers from the pins debug file. [1] https://www.ti.com/lit/ug/spruh73q/spruh73q.pdf Changes in v2: - Remove CONFIG_SOC_AM33XX dependency.
