Mirroring issues

[antirez]

Hi @devbis

While using this driver with the T-WATCH S3 I ran into the problem that the display is rotated 180 degrees.
Reading your code and the datasheet of the device, I tried to set MADCTL_MX and MADCTL_MY in the MADCTL register, however while in this way I can see the device oriented correctly, there is a odd offset: it shows only 2/3 of the display 240x240 area. I don't know if it's some issue with the scrolling feature of the chip or what. I wonder if you know anything about it. Thanks.
