Subject: [Patch v2 6/9] spi: bcm-qspi: Make PM suspend/resume work with SCMI clock management
Date: Sun, 19 Apr 2020 15:23:35 -0400 [thread overview]
Message-ID: <20200419192339.32023-7-kdasu.kdev@gmail.com> (raw)
In-Reply-To: <20200419192339.32023-1-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.
