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	[thread overview]
Message-ID: <20200416174309.34044-6-kdasu.kdev@gmail.com> (raw)
In-Reply-To: <20200416174309.34044-1-kdasu.kdev@gmail.com>

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.
