From c536a9aa7c14d22a9ee9acb6311a32c9c477665f Mon Sep 17 00:00:00 2001 From: Palmer Dabbelt Date: Tue, 25 Jun 2019 01:48:27 -0700 Subject: [PATCH] net: macb: Kconfig: Make MACB depend on COMMON_CLK commit c218ad559020 ("macb: Add support for SiFive FU540-C000") added a dependency on the common clock framework to the macb driver, but didn't express that dependency in Kconfig. As a result macb now fails to compile on systems without COMMON_CLK, which specifically causes a build failure on powerpc allyesconfig. This patch adds the dependency, which results in the macb driver no longer being selectable on systems without the common clock framework. All known systems that have this device already support the common clock framework, so this should not cause trouble for any uses. Supporting both the FU540-C000 and systems without COMMON_CLK is quite ugly. I've build tested this on powerpc allyesconfig and RISC-V defconfig (which selects MACB), but I have not even booted the resulting kernels.
