[PATCH 0/3] fixes and sanity checks for mxs pinmuxing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

this series helped me to find pinmuxing problems on an i.MX28 machine.

The pins either have a pull up, a bit keeper or neither. For example the pin
ENET0_RXD2 has a bit keeper, and so doing

	imx_gpio_mode(ENET0_RXD2 | VE_3_3V | STRENGTH(S8MA) | PULLUP(1))

obviously couldn't enable the pull up as requested. Instead it enabled the bit
keeper. With this series the above call results in a message that the mode is
invalid and the pullup and bitkeeper register settings are not touched.

Note that I didn't test on i.MX23 even though this SoC is affected, too. I
currently don't have an i.MX23 handy, so I couldn't test this part.

  mxs: iomux-imx28: Fix keeper/pullup/drive strength/voltage flags
  mxs: iomux-imx23/imx28: unify mode definition
  mxs: iomux-imx23/imx28: add additional checks on mode
