Subject: [PATCH v3 0/5] powerpc/pm: QorIQ deep sleep
Date: Tue, 2 Aug 2016 19:59:28 +0800 [thread overview]
Message-ID: <1470139172-12699-2-git-send-email-chenhui.zhao@nxp.com> (raw)
In-Reply-To: <1470139172-12699-1-git-send-email-chenhui.zhao@nxp.com>
Changes for v3:
* add mcke-gpios in dts to specify the GPIO pin which works as MCKE signal
Changes for v2:
* Ioremap every dts node used in the patches.
* Check the board compatible string to see if the board supports deep sleep.
* Can not reserve the first page of DDR memory, because PPC64 doesn't support
changing the kernel base address. So still save and restore the first 128 bytes
of DDR memory.
* Still save and restoer CCSR registers in kernel, because bootloader doesn't
know what register values to restore
* Changed copyright and email address from freescale to NXP
Please refer to the version 1:
[1/4] powerpc/85xx: support sleep feature on QorIQ SoCs with RCPM
http://patchwork.ozlabs.org/patch/502549/
[2/4] powerpc: get the physical base address of DCSR
