Subject: [PATCH 0/2] am335x: set pinmux registers from pins debug file
Date:   Sun, 16 May 2021 15:55:29 +0200
Message-Id: <20210516135531.2203-1-dariobin@libero.it>
Precedence: bulk


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.
