Subject: [Patch 6/9] spi: bcm-qspi: Make PM suspend/resume work with SCMI clock management
Date:   Thu, 16 Apr 2020 13:43:06 -0400
Message-Id: <20200416174309.34044-6-kdasu.kdev@gmail.com>
In-Reply-To: <20200416174309.34044-1-kdasu.kdev@gmail.com>
References: <20200416174309.34044-1-kdasu.kdev@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

SCMI only passes clk_prepare_enable() and clk_disable_unprepare(), made
changes to suspend/resume ops to use the appropriate calls so that PM
works for ARM and ARM64 platforms.
