[v2] mtd: onenand: omap2: add dependency on GPMC

[PATCH v2] mtd: onenand: omap2: add dependency on GPMC

Posted by Krzysztof Kozlowski 3 years, 5 months ago

OMAP2 OneNAND driver uses gpmc_omap_onenand_set_timings() provided by
OMAP_GPMC driver, so the latter cannot be module if OneNAND driver is
built-in:

  /usr/bin/arm-linux-gnueabi-ld: drivers/mtd/nand/onenand/onenand_omap2.o: in function `omap2_onenand_probe':
  onenand_omap2.c:(.text+0x520): undefined reference to `gpmc_omap_onenand_set_timings'

The OMAP_GPMC is also a runtime dependency.

Reported-by: kernel test robot <lkp@intel.com>
Fixes: 854fd9209b20 ("memory: omap-gpmc: Allow building as a module")
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

---

Changes since v1:
1. Always require OMAP_GPMC (drop !OMAP_GPMC).
2. Adjust commit msg.
