Subject: [U-Boot] [PATCH v3 04/12] net: macb: Fix clk API usage for RISC-V systems
Date: Wed, 23 Jan 2019 04:25:40 +0000	[thread overview]
Message-ID: <20190123042442.106038-5-anup.patel@wdc.com> (raw)
In-Reply-To: <20190123042442.106038-1-anup.patel@wdc.com>

This patch does following fixes in MACB ethernet driver
for using it on RISC-V systems (particularly QEMU sifive_u
machine):
1. asm/arch/clk.h is not available on RISC-V port so include
   it only for non-RISC-V systems.
2. Don't fail in macb_enable_clk() if clk_enable() returns
   -ENOSYS because we get -ENOSYS for fixed-rate clocks.
