| Subject | [PATCH v3 08/14] MIPS: JZ4740: Qi LB60: Add pinctrl configuration for several drivers |
| Date | 2017-01-25 20:00 +0100 |
| Message-ID | <t3AXw-5pP-21@gated-at.bofh.it> (permalink) |
| References | <t1iV4-Qv-5@gated-at.bofh.it> <t3AXv-5pP-3@gated-at.bofh.it> |
| Organization | linux.* mail to news gateway |
We set the pin configuration for the jz4740-nand, jz4740-mmc,
jz4740-fb, jz4740-pwm and jz4740-uart drivers.
This will permit those drivers to be cleaned out of the custom GPIO code
that they currently use.
