[ Upstream commit 02aeb2f21530c98fc3ca51028eda742a3fafbd9f ]
pinmux_func_gpios[] contains a hole due to the missing function GPIO
definition for the "CTX0&CTX1" signal, which is the logical "AND" of the
first two CAN outputs.
A closer look reveals other issues:
- Some functionality is available on alternative pins, but the
PINMUX_DATA() entries is using the wrong marks,
- Several configurations are missing.
Fix this by:
- Renaming CTX0CTX1CTX2_MARK, CRX0CRX1_PJ22_MARK, and
CRX0CRX1CRX2_PJ20_MARK to CTX0_CTX1_CTX2_MARK, CRX0_CRX1_PJ22_MARK,
resp. CRX0_CRX1_CRX2_PJ20_MARK for consistency with the
corresponding enum IDs,
- Adding all missing enum IDs and marks,
- Use the right (*_PJ2x) variants for alternative pins,
- Adding all missing configurations to pinmux_data[],
- Adding all missing function GPIO definitions to pinmux_func_gpios[].
