Subject: [PATCH] clk: sifive: restrict Kconfig scope for the FU540 PRCI driver
Date: Mon, 13 May 2019 13:07:58 -0700
Message-ID: <20190513200758.15241-1-paul.walmsley@sifive.com> (raw)

Restrict Kconfig scope for SiFive clock and reset IP block drivers
such that they won't appear on most configurations that are unlikely
to support them.  This is based on a suggestion from Pavel Machek
<pavel@ucw.cz>.  Ideally this should be dependent on
CONFIG_ARCH_SIFIVE, but since that Kconfig directive does not yet
exist, add dependencies on RISCV or COMPILE_TEST for now.
