Subject: [U-Boot] [PATCH 04/11] net: macb: Fix clk API usage for RISC-V systems
Date: Thu, 17 Jan 2019 16:33:49 +0530 [thread overview]
Message-ID: <20190117110356.36753-5-anup@brainfault.org> (raw)
In-Reply-To: <20190117110356.36753-1-anup@brainfault.org>
From: Anup Patel <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.
