When bam dma is "controlled remotely", thus far clocks were not controlled from the Linux. In this scenario, Linux was disabling runtime pm in bam dma driver and not doing any clock management in suspend/resume hooks. With introduction of crypto engine bam dma, the clock is a rpmh resource that can be controlled from both Linux and TZ/remote side. Now bam dma clock is getting enabled during probe even though the bam dma can be "controlled remotely". But due to clocks not being handled properly, bam_suspend generates a unbalanced clk_unprepare warning during system suspend. To fix the above issue and to enable proper clock-management, this patch enables runtim-pm and handles bam dma clocks in suspend/resume hooks if the clock node is present irrespective of controlled_remotely property.
