[PATCH] soc: renesas: Provide dummy rcar_rst_read_mode_pins() for compile-testing
From: Geert UytterhoevenIf the R-Car RST driver is not included, compile-testing R-Car clock drivers fails with a link error: undefined reference to `rcar_rst_read_mode_pins' To fix this, provide a dummy version. Use the exact same test logic as in drivers/soc/renesas/Makefile, as there is no Kconfig symbol (yet) to control compilation of the R-Car RST driver.

Let me know if you'd like me to revisit that decision. I had hoped you could still queue it as a fix for v4.12... This is one of the blockers for enabling compile-testing of the R-Car clock drivers in v4.13. Of course some of the other blockers may not make v4.12 neither. Instead of postponing it to v4.13, you could as well drop it, and wait for the better solution in "[RFC] soc: renesas: Rework Kconfig and Makefile logic".

Given that it doesn't appear that the problem resolved by this fix manifests at this time I have queued it up for v4.13 rather than as a fix for v4.12. Let me know if you'd like me to revisit that decision.

I went with this quick fix, as drivers/soc/renesas doesn't have a Kconfig file yet, and introducing a Kconfig symbol would thus be more intrusive.

[PATCH] soc: renesas: Provide dummy rcar_rst_read_mode_pins() for compile-testing
If the R-Car RST driver is not included, compile-testing R-Car clock drivers fails with a link error: undefined reference to `rcar_rst_read_mode_pins' To fix this, provide a dummy version. Use the exact same test logic as in drivers/soc/renesas/Makefile, as there is no Kconfig symbol (yet) to control compilation of the R-Car RST driver. Fixes: 527c02f66d263d2e ("soc: renesas: Add R-Car RST driver") Signed-off-by: Geert Uytterhoeven--- This isn't an issue now, but it does prevent enabling compile-testing of the R-Car clock drivers. As this is a dependency between two different subsystems, I think this patch should be fast-tracked. The #ifdef condition will be revised later, when the R-Car RST driver gains its own Kconfig symbol. --- include/linux/soc/renesas/rcar-rst.h | 5 + 1 file changed, 5 insertions(+) diff --git a/include/linux/soc/renesas/rcar-rst.h b/include/linux/soc/renesas/rcar-rst.h index a18e0783946b66ec..787e7ad53d45f61c 100644 --- a/include/linux/soc/renesas/rcar-rst.h +++ b/include/linux/soc/renesas/rcar-rst.h @@ -1,6 +1,11 @@ #ifndef __LINUX_SOC_RENESAS_RCAR_RST_H__ #define __LINUX_SOC_RENESAS_RCAR_RST_H__ +#if defined(CONFIG_ARCH_RCAR_GEN1) || defined(CONFIG_ARCH_RCAR_GEN2) || \ +defined(CONFIG_ARCH_R8A7795) || defined(CONFIG_ARCH_R8A7796) int rcar_rst_read_mode_pins(u32 *mode); +#else +static inline int rcar_rst_read_mode_pins(u32 *mode) { return -ENODEV; } +#endif #endif /* __LINUX_SOC_RENESAS_RCAR_RST_H__ */ -- 2.7.4
